Historical Weather Patterns for Hat Yai

Hat Yai has very constant temperatures with average highs and lows varying by less than five degrees over the course of the year.
 

The rainy season, which in Hat Yai coincides with the European and North American winters, is not an entirely bad time to visit, since the rain generally falls within the span of an hour or two in the late afternoons. The rain cools down the temperatures a bit and cleans the air quite nicely. With the high temperatures, the rain is not exactly cold. Sometimes it can be like a warm shower.

The rainy season is generally shorter and more pronounced in Hat Yai than it is in Bangkok. The rain increases sharply in October, but then tapers off just as quickly. February and March are the best months to visit if you want to avoid just about any possibility of rain.
