Thailand Seasons

Thailand's three broad seasons

Thailand's government sources broadly identify summer, rainy and winter periods, although regional weather varies.

Mid-February to Mid-May

Hot / Summer Season

Temperatures rise and April is typically among the hottest periods. Beach destinations can still be attractive, but sightseeing in Bangkok and inland areas can feel hot.

Mid-May to Mid-October

Rainy Season

The southwest monsoon brings increased rainfall across much of Thailand. Rain does not necessarily mean continuous rain all day, and some destinations can be especially green and less crowded.

Mid-October to Mid-February

Cooler / Winter Season

This is generally one of the most comfortable periods for sightseeing in many parts of Thailand, although southern coastal weather can differ.
