When to go to each region in Thailand

Bangkok is always hot, although temperatures dip (especially at night) around Christmas and New Year, making this the most comfortable time to explore the city. The heat is intense from February to May, and it rains frequently from June to September/October.

North and Northeast
The north and northeast are cool from November to early February, and nights can be very cold around Christmas and New Year. Take warm clothing if you travel or go trekking here at this time. It rains in the north from July through September, so take light rain gear for trekking. However, these are the best times to visit, as the vegetation is rather parched during the hot season, from late February to early July.

South
The south is very wet from March through November, so if you want to catch the sun, go between February and October/early November.
