|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.
Overall the southern parts of Thailand get by far the most rain with around 2,400 millimetres every year, compared with the central and northern regions of Thailand, both of which get around 1,400 millimetres.
There are three seasons in Thailand, although many people would debate this fact. Summer runs essentially from March through to June, with temperatures between 33 C – 48 C in the day, and not below 27 C at night.
Rainy/Monsoon Season runs from July through to November with frequent heavy rain around 17.00pm. The temperatures range from 32 C during the day to 16 C at night.
Cool Season runs from November through to February with temperatures at 32C during the day, to a bearable 16 C at night, although in the North, it could be as low as 12 C. This also doubles up as the dry season.
During the months of July to November, we recommend that you pack a light waterproof jacket and a pair of closed shoes.
