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.

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.
Update.
Here is another link to rainfall and temperature charts with more detailes information
Thanks for all your work
Thanks for this. Really helpful.
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.
Thanks
Margaret
I have emailed you Margaret
I AM PLANING TO RETIRE IN VIETNAM, AND I AM GOTHRING ALL I CAN INFO ABOUT LIVING IN VIETNAM, AND I WANA THANK YOU FOR YOUR HELP IN THIS MATER
You are very welcome…….. see you over here
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!
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
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!
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.
August is a good time for the central regions. I have sent you an email
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
im going to hochi minch city late november (25) is it heavy rain during this time?..tq
sol,

Fantastic information and tips .. throughly enjoyed reading of your ventures in vietnam!!
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?
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
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
If travelling to the Central area at that time, keep your options open
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.
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.
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.
June is a great time to travel. Weather should be nice with perhaps afternoon rains.
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
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.
