Thailand has a tropical monsoon climate, with temperatures normally ranging from an average annual high of 38 °C to a low of 19 °C.  In the southwest of the country monsoons that arrive between May and July (except in the far south of Thailand) signal the beginning of the rainy season, which lasts into October. November and December mark the onset of the dry season. Temperatures begin to climb in January, and a hot sun parches the landscape. The dry season is shortest in the South because of the proximity of the sea to all parts of the Malay Peninsula. With only minor exceptions, every area of the country receives adequate rainfall, but the duration of the rainy season and the amount of rain vary substantially from region to region and with altitude.
