What would you like to know about the weather in Thailand?
Ever wanted to fry an egg on the road? Visit Thailand in April. April is, quite simply, blisteringly hot. Average temperatures can soar into the high 30s and the heat is just oppressive. The middle of April sees the Thai New Year (Songkran) celebrated and it thankfully involves a lot of water throwing — forming your single opportunity to cool off ever so slightly.
Temperature-wise April is by far the most unpleasant month of the year to be in either Bangkok or the central region. In Kanchanaburi to the west the daytime average high is over 38 degrees. That is hot — and all the more reason to get a room that floats on the river while you are there. There is little rain to speak of. Get an air-con room if at all possible.
The amount of rain in Eastern Thailand continues to slowly ratchet up through April and the temperatures in this area are not as high as elsewhere (though you can still expect temperatures in the mid 20s to mid 30s range). Ko Chang is hugely popular in April — both to escape the heat of the plains, but also for the Songkran holiday break.
Temperatures in the mid 20s to high 30s, a terrible eye-stinging haze and little rain all come together to make the northern capital of Chiang Mai thoroughly unpleasant in April. As it is also one of the most popular places to celebrate Songkran, the hordes descend in early April, making getting a reasonable room a little more of a challenge.
If you thought northern Thailand was hot in April, you should try the Northeast! Oppressive heat into the high 30s is the norm throughout April. You will need an air-con room. If you are touring this part of the country in April, try to spend some of your time along the Mekong as temperatures are ever so slightly lower and, well, there is a river to jump in!
April on the Andaman Coast sees more rain (expect rain every few days) but if you're in luck, you can have long stretches of good beach weather on this coast through April. This is generally the last month some places in the far south remain open as in May, with the commencement of the monsoon season, reduced availability of boats equates to fewer guests. Temperatures are low 20s to low 30s.
