What is the weather like in Nha Trang in September — is it rainy season?

This year (2026) rains unusually continued until June, even though the dry season officially starts in April — weather can vary a lot from year to year.

In November the sea gets very rough and typhoons are possible, unlike October, which is considered a transitional month with variable weather.

One commenter claims Nha Trang's weather is similar to Danang's, and in both places the rainy season starts already in September — differing from other views in the discussion.

A traveler asking about early September — based on others' experience, rain is still rare at that time and the weather is generally fine.

The second half of September and October are considered among the best times to visit: heat eases, fewer tourists, and rain is still light. February–March is also a good period.

In March, rain can last several days in a row (up to 5 days), while in September it may rain only a couple of times total. Heavy rains typically start closer to November.

April is a transitional period with waves, rain, and possible beach debris — it marks the beginning of the off-season.

A trip from October 20 to November 20 showed great weather for the first three weeks, with storms and flooding only in the final week of November.

May and September see price drops on tours — good time to find last-minute deals. Peak season (June–August) has the highest prices.
