Thailand’s climate differs between the north and the south. In northern and central Thailand, it’s very hot and dry from March to June, with April being the hottest month; May to November is dominated by the southwest monsoon, and is when the region sees its heaviest rainfall; and from November to February, its cooler but dry. In the south, it rains intermittently all year long across the region, as the wet season does not run at the same time on both the east and west side of the peninsula. On the west coast of southern Thailand, rain is heaviest from April through October, and on the east coast of southern Thailand, the most rain falls between September and December. Overall, southern Thailand receives a greater amount of rain than northern and central areas of the country over the course of the year.
