Thailand's climate is tropical, high both in temperature and humidity, and dominated by monsoons. April and May are the hottest months of the year, when even the locals are moved to complain about the heat. June sees the beginning of the South West Monsoon, and brings with it the rainy season, which continues intermittently until the end of October.
From November to the end of February the climate is much less trying with a cooling North East breeze and a reduction in the humidity level. This is also the main tourist season, and the best time to visit Thailand.
The north and north-east are generally cooler than Bangkok in winter, and hotter in summer. In the far north, around Mae Hong Son temperatures can occasionally drop as low as 2 degrees.
