Thailand seasons from Summer to Winter
Thailand Seasons. The southwest Monsoon comes from the Indian Ocean with rain-laden clouds, from about June to October. It dose not rain every day so there is still plenty of sunshine. The humidity makes it feel hot and sticky. When it starts to rain, it only takes a few seconds for the roads flood and the traffic to come to a standstill. In most tropical countries there is no point in wearing raincoats as you will get wet from sweating than you will from the rain! “Monsoon comes from the Arabic mawsin (season)”. It refers to South Asia’s seasonal winds (not heavy rain). In Thailand, the southwest monsoon is the rainy season; the northeast monsoon is dry, called the cool season.
Cool Season: The northeast monsoon from central Asia usually blows from November to February, bringing relatively cool, dry conditions to Thailand. This is the best time to visit Thailand.
Hot Season: Between the two monsoons, March to May, the land heats up, creating an area of low pressure above it. Eventually the high pressure over the Indian Ocean moves inland, and the monsoon cycle begins again. This is the hottest time of the year so the school closes for a two month long break.
