and the West Weather: The climate in this region is very
similar to that in Bangkok and the central region; hot and dry from
November to February, hotter and dry from March to April and hot and
wet from May to October. Once again rain isn't usually constant in
the early wet season but can be in September and October. In the mountainous
areas, such as Chong Yen at Mae Wong National Park, the weather can
get quite chilly at night, particularly in December and January.
