Best time to visit Nha Trang
Vietnam · 20-year averages
February is the best month in Nha Trang, scoring 93 out of 100, with August the weakest at 51. The 42-point spread means timing is worth planning around without being decisive. The good window runs January to March — 3 months within ten points of the best.
May is the warmest month at 30 °C and January the coolest at 25.4 °C — a 4.6 °C spread across the year. Around 60 days a year top 30 °C, concentrated in May and the months either side.
There is a real wet season here. June to November carry the rain — up to 26 wet days in a month — while January to April drop as low as 3. That 23-day gap is the biggest single difference between a good month and a bad one in Nha Trang, and it moves further than the temperature does.
The sea never drops below 25.3 °C, so swimming is on the table year round. Daylight barely moves: about 12.8 hours whatever the month, which removes one variable from the decision entirely.
The three strongest months are February, March, January. The one to think twice about is August. Each month below has its own page with rainfall reliability, extremes, daylight, sea temperature and crowd levels.
