Thailand Weather

In northern Thailand the seasons are clearly defined. Between November and May the weather is mostly dry, however this is broken up into the periods November to February and March to May. The later of these two periods has the higher relative temperatures as although the northeast monsoon does not directly effect the northern area of Thailand, it does cause cooling breezes from November to February.

The other northern season is from May to November and is dominated by the southwest monsoon, during which time rainfall in the north is at its heaviest.

The southern region of Thailand really has only two seasons — the wet and the dry. These seasons do not run at the same time on both the east and west side of the peninsular. On the west coast the southwest monsoon brings rain and often heavy storms from April through to October, whilst on the east coast the most rain falls between September and December.
