In the North, particularly in Chiang Rai, Mae Hong Son and Chiang Mai the dry season last six months, five months on most part of Central and North-eastern Thailand, and only two months in Surat Thani. In Mae Hong Son the temperatures fall as low as 2 C. In Phuket, it rains in May and in October. The rainy season in Central Thailand is during August and September. The north-east and north are commonly frigid than Bangkok in winter, and warm in summer. Bangkok’s temperature is mostly hot, intense in April around 35 C and decrease approximately 30 C in December.
