Weather in Thailand in February
Hot and wet or hot and dry?
February represents the tail end of Thailand's peak Christmas season — the crowds thin out a little, but the weather remains excellent. Everywhere from Bangkok north will see a slight increase in the chance of rain, while in the South the chance of rain will recede even further. Temperatures will remain oscillating around the low 20s to low 30s mark.
Bangkok and Central Thailand
Bangkok and Central Thailand see a slight rise in temperatures, accompanied by a small uptick in the chance of rain. That said you're still only talking about one or two days of rain in the month. This is the last "cool" month till October or November.
Temperatures will be slightly lower than in Bangkok and Central Thailand, though there will be more rain — perhaps some rain every four to five days. February remains an especially popular time of the year to visit eastern Thai islands like Ko Chang and Ko Kut.
February sees Northern Thailand begin to make the transition from the cool to the hot season. Evenings will remain a little cool, but during the day it will warm up. Those going trekking should still check that blankets are a part of the package. Chance of rain remains very low. This is a good time in northern Thailand as the haze from the burning hasn't really got going and the weather is quite reasonable
The Northeast's weather in February is really an extension of Central Thailand, albeit a little cooler come the evenings. Daytime temperatures are beginning to rise. Expect a couple of days with rain month, but not more. This is probably the last month in which the heat isn't oppressive, to visit the Northeast until the rainy season ends.
On the Gulf Islands and the southeast coast, expect temperatures in the mid to high twenties. The rains of January should have backed off making for all round excellent beach weather. Ko Samui, Ko Pha Ngan and Ko Tao are excellent in February.
Like January, February is one of the best months of the year weather-wise to visit the Andaman Coast of Thailand. From Phuket to Trang and beyond, expect excellent weather, a lot of sunshine and perhaps just one or two days with rain. The temperature sits around the mid 20s to low 30s range.
