Weather
The Thais divide the year into three seasons: the cool season, hot season, and rainy season. For most westerners, this translates to "hot," "really hot," and "really hot and wet." Temperatures rarely drop below 25° C (70° F). See the banner below for current conditions.
Historical Weather Patterns for Hua Hin
Hua Hin 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 Hua Hin coincides with the European and North American summer and autumn, 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.
In all December and January are the best months to visit if you want to avoid just about any possibility of rain.
