Weather in Vietnam… a Hot topic


Ok here it is,  everything you wanted to know about the weather in Vietnam. I usually start my writings from South to north, so let me be a rebel and start in the north.


The climate of Sapa is highly seasonal, with a subtropical climate in the summer and a temperate climate during the winter. Average temperature for Sapa town is 15.4ºC, with a maximum of 29.4ºC and a minimum of 1ºC. Sapa also experiences a marked wet season from May to September, with the heaviest rainfall occurring in July and August. The weather is also notorious for changing frequently and quickly. It is said that only in Sapa, one can experience many different seasons within only one day.

December-Wet winter starts and gets worse in the later days of the month. It can get qite chilly.

Halong Bay

Halong’s climate is humid and tropical. With a hot, humid summer and dry, cold winter; Halong’s  temperature varies from 15ºC to 25ºC.Annual rainfall is between 2000mm and 2200mm. Ha Long  bay has typical diurnal tide system (tide amplitude ranges from 3.5-4m). The salinity is from 31 to 34.5MT in dry season and lower in rainy season. It is possible to visit Ha Long Bay year-round, with the best time to visit from October through April, although during the winter months of December, January and February, the weather can be cool and overcast with low visibility.  During the summer months from May to September, temperatures rise and storms are more likely during the rainy season.


Hanoi has typical North Vietnam climate, with a cold and dry winter (when temperatures can drop to as low as 6°C – 7°C) and a hot and extremely humid summer (temperatures can climb up to a maximum of 35°C). Spring is characterized with light drizzles while the summers bring heavy rain. The best time to visit Hanoi is around September to November or from March to April for their milder temperatures and pleasant weather.

The dry season (from March to August) has a maximum temperature of 400 C and the colder, rainy season (August to January) has temperatures that can go down to 19,70 C. In higher areas (on mountains, highlands) the temperature is generally cooler. From March to August will be the best time to visit Hue, especially between March and April when the temperature is more pleasant, though rainfalls are still likely. Hue sees fog and rain quite frequently, even when the weather across the Hai Van Pass in nearby Danang is sunny.  During the rainy season, between September and January, rain is more frequent and can be heavy.

Hoi An

Somewhere between tropical and climate. The temperature is warm throughout the year (average 29°C), yet hotter around months June and July and cooler around December. Hoi An is affected by monsoon winds. The city will be constantly raining from September till January, and dry for the rest of the year. Overall, the best time to visit Hoi An is between May and June. February and April are among the best time to visit Hoi an when rainfall is low and temperatures are pleasant. The temperatures can get hot during summer time and during the rainy season, particularly during October and November, rains can be frequent and heavy.


Nha Trang is extremely lucky to not be influenced by monsoon winds that turn the rest of southern Vietnam into water six months every year. Nha Trang has a warm, fair and beautiful climate nearly all year round, with the exception of late October, November and early December. The best time to visit Nha Trang would probably be March or April. The least windy months of the year are May, April and June. Nha Trang in general is not windy enough to windsurf, with the exception of Doc Let beach (35 km north of Nha Trang), which is usually reserved for experts.

Surrounded by mountains and pine forests, Da Lat has many characteristics of a temperate climate. The average temperature here is 18–21°C, with highest temperature 30°C and lowest 5°C. Dalat also has the two season climate typical of South Vietnam, with a monsoon season from May to October and a dry season from November to April. Dalat is never stormy and only has occasional heavy winds from the ocean through the mountainless East side of the city.

Mui Ne

Mui Ne lies in the monsoon tropical zone, with 2 district seasons. The rainy season is from May to October and the dry season from November to April. Dry season normally means NO RAIN. Mui Ne lies in the emerging Binh Thuan Desert and is prone to drought. Onset of rainy season can bring flash flooding and extensive errosion. Rainy season brings lush green foliage and the return of birds, butterflies and other wildlife (and takes away the tourists). Rain is usually for an hour, once or twice a day (typically afternoon and evening), during the rainy season. The yearly average rainfall varies between 50 and 100 cm. The average relative humidity is 79%. Because Mui Ne receives very little rain, it is also sunnier, and thus feels hotter than Nha Trang or Ho Chi Minh City.

Ho Chi Minh City weather and climate

Located in South Vietnam, Ho Chi Minh City city has a tropical climate. The average humidity level is 75%, average temperature is 28 °C. The city is generally warm, and has a monsoon season from May to November and a dry season from December to April. During the rainy season starting from May to November, rains can be long and heavy, but often are short daily rains that clear quickly. Generally, the best time to visit is during the dry season from December and April, although the coolest months are October through December.

Phu Quoc

The island’s monsoonal sub-equatorial climate is characterized by distinct rainy (June to October) and dry seasons (November to May). The annual rainfall is high averaging 2,879 mm. In the northern mountains up to 4,000 mm have been recorded. April and May are the hottest months with temperature reaching 35 °C. Trips to Phu Quoc can be made all year round, but the best time is dry season when the sky is always sunny, clear and blue.

So there you have it!! I wish to thank all of the sites I copied from. It was a bit hard compiling this information into one place, and your sites helped immensly.

  1. Hi Owee

    We arrive into the region 28th August-10th September. Would like to visit Siam Reap, Phnom Penh, HCMC and another TBC destination in southern Vietnam.

    Would you suggest Vietnam or Cambodia first from a weather perspective? Ie. does the weather worsen in HCMC as September goes on, meaning it’d be sensible to go there first? Or vice versa?

    Also, any recommendations for another destination in Southern Vietnam, ideally on the coast/beach? Is the weather in Hoi An too unpredictable in late Aug/early Sept?

    Thanks in advance

    1. I think Vietnam first as mid September is the start of rainy season in central Vietnam. It will already be rainy seaon in Cambodia so perhaps the later the better. Hoi an is really not a beach destination. Look at Mui Ne, Nha Trang, Quy Nhon, Phu Quoc and also Sihanookville

  2. Hello Owee-
    I just discovered your site a few minutes ago as I am considering a last minute tour of Vietnam from July 17-July 27, starting in Hanoi, Halong Bay, Hue, Hoi An, finish Ho Chi Minh City. I would expect heat and humidity, but would I be miserable? Thanks for your thoughts.

  3. Wow wow wow what an awesomesite, you sure take much time out in carefully answering all queries / questions. I am a single 63year woman from South Africa wanting to travel in October. First to Bangkok then by train to Cambodia and finally to Vietnam. Firstly is it safe for a woman of my age travelling to Cambodia and Vietnam alone. Then comes the challenge of the weather. I am only able to travel in October, so where would it be best for me to head from Cambodia in Vietnam. Many thanks and much blessings

    1. Thanks.
      Vietnam is very safe. Most people here are respectful and friendly. Only tourist area scoundrels can be a bit of a pain but you need not worry about personal security. Just yell police if hassled and they run away. Sadly, October is not the best time but……… Saigon and the Mekong , Hanoi, Sapa and Halong Bay also ok. It will be rainy season starting from Mui Ne all the way up beyond Hue. Unfortunatly Hoi An and Hue can have very bad weather at that time. Nha Trang is 50/50. The central Highlands will be wet and dry with micro climates.

  4. I’ve been enjoying reading about the weather and ideas traveling to Vietnam and Cambodia. My husband and I want to take a 2-3 week trip, and would love to go on a Makong river boat cruise, since we are in our mid 60’s and want to take it easy traveling. But the touristy ones can be so expensive. What is this “non touristy” one I’m reading about above? Plus what would be the best time of year as far as weather to do the Makong? We would be coming from Hawaii and have to consider our flight costs also.
    Any other bits of advice?
    Thank you and aloha from Hawaii, berta

  5. Hi Owee,

    Thank you so much for this great info, me and my partner are looking to fly into Ho Chi Minh City on 17th April until the 3rd may for my birthday, we would like to do some cultural sight seeing and then on to a beech destination for the last 4-5 days as we both love to snorkell, is there anywhere that you can recommend, we do like going off of the beaten track a little, somewhere that is not so crowded and full of tourists,

    Many thanks

  6. Hi Owee
    Your site is wonderful, full of useful information and a credit to you.
    I am planning on visiting Vietnam at the end of August for 2 weeks and after a beach holiday. Which of the following places would have the best weather Danang Nha Trang , Phu Quoc or Con Dao island.

    I would also love to do the non touristy Mekong River tour that you spoke about as well

    Look forward to your reply

    Cheers Sue

  7. Hi Owee,
    what a masterpiece you wrote about Vietnam’s weather! for couple of years now, I have the unexplained need to go and visit Vietnam. We (family with 2 teens) are experienced travelers, and have been also in some Asian countries (Thailand, Malaysia, Indonesia, Sri Lanka). Due to job requremetns only end of June till midd. of July holiday trip (arround 18-20 days) is possible, so I’m thinking about going to North (Sapa etc.) first and than prlong to South. Will work on detailed interary later on. What do you think about this idea? I really want to se the North of the county as well. We can handle some thunderstroms/rain, although wouldn’t be so great having pouring rain for days…
    thanks in advance and perhaps see you…Mojca

    1. Thanks for the compliment. June is a fine time with sunny days and often an afternoon shower to cool things down. July will be a bit more wet but still ok. June better because still slow season. July will get much busier.

  8. hi owee
    fantastic web site I have got some great info from it thank you!
    we are traveling down to danang 24th feb through to 4th march for a beach break . having done bit of research not so sure the weather is going to be sunny beach weather would you recommend having a back up plane like carry on down to Nha Trang or further south and is itpossible to fly down from danang or go by rd only in Vietnam for 2 weeks so time is a consideration
    thanks brian

    1. The weather should be just fine. Danang has resorts on the beach, however, Nha Trang is more known for beaches. There is also a lot to do. You could also look at Hoi An.

  9. Wow Owen..I wish I found your site earlier. Ive been doing sooo much research getting conflicting information from everywhere and then your site. Everything I need to know, it will make it alot easier to plan my family trip for mid oct- early nov. Thankyou soooooo much!!!!! (I must say that the website seat61 has also been a great help on planning the train journeys too) Basically Ive decided to make 2 plans incase of bad weather in danang & surrounding areas. If its bad weather I will go directly from Hanoi to HCMC and then visit warmer places like Mui ne & if weather is ok also fly in & out of Nha trang. If the weather is ok we will visit Danang etc then on to HCMC etc. If you have any input it would be much appreciated. Thanks again mate. 🙂

    1. Good idea to have a plan B. Danang Hue and Hoi An are often hit by very bad weather at that time. The weather is much more stable fron Nha Trang south. Feel free to email me if you need any help. I am not hard to find

  10. Hi Owee,

    Myself and my boyfriend are looking to travel to vietnam over the summer, but are unsure of when to go and where the best places would be for weather and value for money. We’re looking to see good sights such as at Halong bay, but also would like beaches too!


    1. I suggest March through June as the best time to visit Vietnam. The best of Vietnam in my opinion is the highlant route between Hoi An and Nha Trang. Check out the itinerary section for more ideas of where to travel.

  11. Hi Owee,

    very good info you have here.. really well written.

    I have a quick question. My self and my wife are travelling to the south for our honeymoon in July.
    will it rain a alot or be overcast?

    a reply will be greatly appreciated


    1. Typicly……….You will most likely wake up to sunny skies and at 2 or 3 pm, the rains or showers will move in tocool everything down for a few hours…..

  12. Hi, your website has given fantastic advice for travelling to Vietnam. I have just a quick question, we were originally planning to travel to Hanoi, to Halong Bay and then down to Hoi an in May. However, we are unable to travel at this time due to no-one looking after the dogs 🙁 so we are hoping to postpone until the end of July, what will the weather be like in these regions during this time? Is it worth coming for a beach holiday then?

    Thanks, any help would be great.


    1. Yes, July will still be beach weather however, you are not going to the best beach locations. There will most likely be afternoon rains up north.

  13. I want to travel for 9 days in November would like culture markets and beach with sun bathing weather can you help?

    1. Take a look at Phu Quoc or Con Dao island. It probably has the best beach weather at that time. The mainland can be rainy and rough waters

  14. Hi, from reading your site, which is fantastic I must say, it appears that in December the weather is better is the south? We are really keen to visit Vietnam in December for a week and Hanoi is top of my travel partners list however I would really like some beach time. Do you have any recommendations?

    1. December is quite chilly in the north. December can be a hit and miss for Nha Trang beach, but the warmer weather usually starts from here south. Mui Ne will be very windy. I suggest looking at Phu Quoc for your warmest and calmest beach destination even though it might be peak season and a little pricey….. Otherwise right here in Nha Trang is your best bet.

  15. Thank you for your great site. We’d value you opinion on when to travel in North Vietnam – Hanoi, Ha Giang, Mai Chau areas.
    We can only go between February and August and would like to see rice growing ( maybe that is out of season ? ) and green countryside. We have been to Thailand and Cambodia in March and February and it was very dry.
    Maybe North Vietnam will be different ?

    1. Thanks for the compliment
      Do not worry, you will see a lot of green. Sepending on area, you will see new and old crops as you travel. The best months in my opinion are Mar-June. Check my weather chart page to dee where is wet and where is dry

  16. Hi Owee. first thank you for your fantastic and really helpful review.We are traveling to Vietnam/Cambodia @ end of Oct for 3 weeks , heading north to south ; Hanoi 3 nights /plus 1 over night Halong bay cruise / Hue 2 nights/ car and driver day trip over Hoi Van Pass /Hoi An 3 nights [fingers crossed for sun booked in @ beach resort] H.M.C . 3 nights/ Phnom Penh 2 nights/SiemReap 4 nights. You have ans. a lot of my questions already ,but we would like to know if we need warm clothing or light summer clothes for this trip? We want to travel as light as we can so would welcome your advice .Think we will bring light rain coats after reading your weather report, thanks again for the enjoyable read, Normaloulou. P.S. ever been in Cambodia?

    1. Sorry to see you will not be visiting us in Nha Trang…….Keep Nha Trang in mind as plan B if it is all typoons or terrible weather in the Hue/Hoi An area. Yes pack light. Even though the odds are very high you will get wet in Hue and Hoi An, rain gear is available everywhere for a low cost. Unless you are very large people, most clothing items can also be purchased. Try to do so away from the main tourist areas (perhaps market in Hue or Hanoi) as Hoi An is one of thwe priciest destinations for clothing in Vietnam. You should be fine with light cloths and shorts for your whole trip otherwise. I wear shorts and tee shirts all year around except in Dalat and Sapa where it can get cold.

  17. Owee – Many thanks for sharing your experience on here, TA, etc.

    We are planning a trip to Vietnam at the start of January and will be spending a few days in Hanoi, and then would ask for your advice about 1 week beach holiday before finishing in How Chi Minh City.

    Will it be too cold in the second week of January to go swimming in Nha Trang? Your weather / climate links show that it is a bit warmer in Phu Quoc, so maybe we should go there instead???


    1. January is often a month of harder waves and sometimes a bit of wind however, the beaches are in my opinion nicer in most instances. There is a lot more in the way of entertainment and such. Beach weather is most likely better in Phu Quoc and if staying at a resort, that might be a better choice. Be aware that it will be high season in Phu Quoc and much more expensive. There are a couple of very nice beaches on the south end of the island….. I would pick Nha Trang myself because of the many things to do besides the beach, but if calm waters are what you are looking for, the island is a better choice.

  18. Hi,
    This is really helpful info, just to be more specific for us. I ma travelling next july 2013 for 3 weeks but want to do a whole host of different bits and bobs, what do you think is better, north to south or south to north, would like to finish on some nice sun bathing weather on our honeymoon


  19. Hi Owee,

    I’ve been to Vietnam 7 times, especially around Danang/Hoi An for work. My fiancé and I love it so much we want to honeymoon there in mid march next year. Our plan is to hang out in Saigon a few days (cause we love it) and then chill out somewhere a bit special and private e.g. One of the six senses properties. But when I was in Danang last month I noticed the intercontinental danang was nearing completion and looks quite a special place. So here’s my question – Danang in mid march – is it hot enough yet for days lazing in the sun and swimming, or are we better off targeting one of those properties closer to nha trang/mui ne? Sitting in 16 degrees Sydney right now, it’s hard to get a good feel for what 24-27 average highs actually feels like!

    My other question is about nha trang. I was there as a back packer in about 1o years ago and remember it being fun, but it does get a lot of negative press these days. After 3-4 days away from the world, we want to stay at a place on the beach (nice hot days) but with reasonable nightlife options. In your opinion is nha trang the place or would we be better off in a place like mui ne? Loved Mui Ne but would want it to have a few more nightlife/bar options than what we had about 5 years ago.

    Sorry for all the questions, but looking for any advice to have the best honeymoon.


    1. The bad press is silly in my books. Some of it is from what Nha Trang used to be but the city has changed a lot and is not deserving of the bad rap. Most of the bad things that happen are in one square block surrounding the sSailing Club where the local scammers know drunk foreigners are.
      March can be fine but if windy 24 can feel really cold. I might book short term with intention to extend and head south if too miserable

  20. we arrive in Hanoi on 18th November 3 nights , will have a 1 night Halong Bay trip. we then fly to Da nang, Nha Trang for 4 nights and Ho Chi Min City leaving on 30 th November . Will we need to bring warm clothes, particularly for Hanoi? After recent reading, I guess that the weather wont be too beachy in Nha Trang . Can you give us an insight what to bring please. ( Husband and wife, first visit to Vietnam)

  21. Hi Owee, I’m planning a beach holiday for my family on 2nd week of dec. planning for 3 nights Hanoi, 2 nights Hue, and 4-5 nights in Fusion Maia. My concern is that given it is winter in vietnam, whether the weather will be too cold and rainy for us to chill out by the pool and beach and hence a waste to splash out that much money on a pool villa. I’m still really keen to visit Vietnam and hoping for your perspective.


  22. I and my family total 3 person already booked a flight to Danang from 23-09-1012
    to 30-09-2012.Is it nice and best time to visit Danang,Hue & Hoi An?Any typhoon,
    heavy rainfall?

    1. The rains often start in Mid September as do the storms. The best months to Visit that area is March – July. Hopefully it will be fine, but have a back up destination to go to is weather is bad.

  23. We’re visiting Vietnam for 2 weeks from September 9th, flying in and out of Ho Chi Minh.

    Our plans were to visit Phu Quoc, Hoi An and Halong Bay.

    We are hoping to see as much sun as possible and was wondering what order is best to travel in.

    Thanks so much for your help.

    1. Wow Katrina, a very long distance for 2 weeks. You will find 2 week sample itineraries on the link on top of the page. just replace one of the destinations with Phu Quoc, and be sure to fly everywhere

  24. Hi
    We are looking at coming to Vietnam from 7 september to 28th september. How is the rainfall then, we are worried its rainy season?
    Also which way should we travel?
    Should we start in Ho Chi Minh and head North to Hanoi? Or other way down?
    We also want to see Siem Reap and Ankgor Wat….should we do this at the beginning or the end?
    Thanks so much in advance

  25. Thanks so much for putting this together. We are heading over for first 3 weeks in August. Do you think start from the north, Sapa, HLB etc then head south?
    We want some beach time as well, would it be a relying on a good beach stay mid way down the coast? Or just be better to save our beach time for the south?
    Thanks heaps 🙂

    1. Nha Trang is about fun and beaches. Start wherever you can get the best deal on a flight. I usually prefer the south, but everyone has their own idea.

  26. Hi – we are doing some hurried planning right now to go visit Angkor, Hue, HoiAn, Halong and Hanoi in that order during last week of June and first week of July, what should we expect weather-wise ? Much appreciate to hear your comments . suggestions.
    thank you.

  27. Hi, All your info is excellent & I have read & re-read weather info for October. If we continue we our plan to come to Nha Trang in October (23rd) would we expect any warmth & sunshine for the beach or is that a big ask? You mentioned on your site that typhoons tend to head more to Hoi An so am hoping that leaves NT as a possibility still.I realize Mui Ne & Phu Quoc are options but do not really believe they have the best combinations of beach, shopping and sightseeing from all that I have researched.We are 1st timers for Vietnam hence the uncertainty.

    1. Hopefully you will have good weather, but it is a hit and miss. This year was quite nice where last year was awful. In my opion, Nt is a much better destination than Phu Quoc or Mui Ne for beaches, but be prepared to move south is bad weather hits.

  28. Thanks for your information. My sister and I are travelling early Oct to Vietnam and not sure whether to go North or South first. We will have nearly 3 weeks. Sometimes I think Oct looks great then in other areas it looks not so good!!!! Kate

  29. Hi Owee,
    Thanks for all the weather info, it’s been really helpful. We are flying in to HCMC mid-March and over a three week period making our way up north to Hanoi with side trips to Halong Bay and Sapa. My query is do we need to pack warm jackets for Sapa for early April? I gather for the rest of Vietnam over that period we will only need T shirts. Is this correct?

    1. You should not need jackets….. travel light. You can always purchase winter coasts donated by NGO’s for 1 or 2 dollars if you need them

  30. Thank you for such detailed information. We are in Vietnam from mid July to Mid Aughust – not the greatest of times but we are dictated by British school holidays! We fly to Hannoi – looking at your data it looks as though we need to head south – but be prepared for a sousing! Halong Bay was somewhere we wanted to go and may take a gamble.

    1. I think you will find that most morning will be sunny and nice until about 3 pm when the clouds will move in an give you a good cooling off 😉
      The Central regions will probably have the driest weather at that time of year

  31. I’m travelling to Vietnam in August, and would like to spend some time in the south (including the Mekong Delta) and the central regions. Does the Mekong Delta tend to flood at this time? I also wondered whether there is an area in Vietnam which is better suited to travelling in August. Thanks for your help!

  32. Hello,

    First of all, thanks for all the information! I am planning a trip to Vietnam, Laos and Cambodia in September and wanted to know if, given the weather patterns, it would be a better idea to go from South to North or vice versa. Thank you so much!

    1. At that time of year, from south to north might be the way to go as the Central regions start their rainy seasons in about Mid September


  34. Hi Owee
    I’ve spent ages reading your “weather” site – it’s fantastic and really helpful. We had intended to travel to Vietnam (going from north to south) in October but having read your comments we think it might be better if we delay our holiday to March/April next year. What would you advise? Our other date would be June.
    I would really appreciate your comments and suggestions.

        1. I do not want to discourage travelers from coming in October, but one must be aware that it is the middle of the rainy season. The odds are just as good in Nha Trang that you will get no rain. When it does rain, it can rain hard and heavy flooding the streets. As long as travel plands are not abrupted, it can be chalked up to part of the excitement. Further north in Hoi An/Danang/Hue are the hardest hit. I guess It all depends on your wet tolerance level. Check out my blog page here for rainfall charts

      1. Dear Owen
        My partner and I are planning to visit Vietnam, Cambodia and a two day cruise on Halong Bay.

        The trip consists of 3 nights in Ho Chi Minh City, 5 nights in Hoi An, 3 nights in Siemens Reap, 3 nights in Hanoi and I night cruising in Halong Bay.

        I would like to go in either Late August or late September and wondering what the weather would be like ie to sight see as well as sun bathing?


        Mick Drameh

        1. Weather should be ok. Hoi An can sometimes suffer from early rains. I suggest splitting up Hoi An and spending 2 nights in Hue. Hoi An is ok if you want a resort and lots of tourist gift stores but it can all be seen in 2 days.
