Thailand in April

Heat, water and a national party

April is Thailand at full temperature. Afternoons pass 35°C almost everywhere and push higher inland; the air shimmers, and life sensibly retreats to shade, water and iced fruit. Then, in the middle of it all, comes Songkran — Thai New Year, celebrated 13–15 April — when the entire country cools itself down with a nationwide water fight that is impossible not to enjoy.

The coast is where April makes sense. On the Gulf, the sea is calm and genuinely bathwater-warm, and the beach towns catch a breeze the inland cities never see. Ban Krut does Songkran the small-town way — families, soaked pickup trucks along the beach road, and everyone back in the sea by late afternoon — while Bangkok and Chiang Mai throw the huge, famous versions.

Thailand's hottest month — 35°C+ is normal, more inland
Songkran, Thai New Year, is celebrated 13–15 April nationwide
The sea is bathwater-warm and calm on the Gulf coast
Book transport and rooms early around Songkran — the whole country travels

Good to know

Book everything around Songkran (13–15 April) early — transport and rooms sell out well ahead.
Carry a dry bag during Songkran; phones and passports will get splashed anywhere in public.
Beat the heat like locals do: out at sunrise, shade or sea at midday, active again after four.
April is peak mango season — mango sticky rice from a roadside stall is the month's essential taste.

Coast by coast: where the weather is best

Gulf coast: hot but liveable, and the sea is the payoff. Ban Krut, Hua Hin and Chumphon serve calm, warm water and breezy evenings; Koh Samui, Koh Phangan and Koh Tao stay settled, with Koh Tao's fine diving conditions running on from March. If you are in Thailand in April, being able to fall into the sea all day is the difference between suffering and holiday.

The Andaman coast is similarly hot, with its first pre-monsoon showers arriving late in the month as its season winds down. Bangkok is at its fiercest — 35°C+ and humid — so pace sightseeing hard. The north is hot, dry and often still hazy in early April; the burning season usually eases as the month ends, but it is not prime trekking time.

Songkran, and how to plan the month

Songkran (13–15 April) is the event. In Bangkok and Chiang Mai it becomes a vast, exuberant street water battle; in beach towns like Ban Krut and Hua Hin it is gentler and family-flavoured. Either way: everything wet-proof, phone in a dry bag, and surrender to it — staying dry is not an option. It is also Thailand's big travel holiday, so trains, buses and rooms fill well ahead; book that window early.

Outside the festival, build days around the heat. Sunrise is the Gulf coast's cool, beautiful hour — walk or cycle then. Spend midday in the sea, in the shade or over a long lunch, and re-emerge after four. Mango season peaks in April, so eat khao niao mamuang (mango sticky rice) shamelessly and often.

Frequently asked questions

How hot is Thailand in April?

April is the hottest month of the year. Afternoons of 35°C or more are normal, and inland cities can run hotter still. Coastal towns on the Gulf are more bearable thanks to the sea breeze and warm, swimmable water.

What is Songkran and when is it?

Songkran is Thai New Year, celebrated nationwide on 13–15 April, best known for its huge public water fights. Expect to get soaked anywhere near a town centre — and expect transport and hotels to be heavily booked around those dates.

Is April a good month for the Gulf coast beaches?

Yes, with the heat as the caveat. The sea at Ban Krut, Hua Hin, Samui and the islands is calm and bathwater-warm, mornings and evenings are lovely, and the swimming is the best answer to the temperature.

Should I book ahead for travel in April?

Around Songkran, absolutely — it is Thailand's biggest holiday and the whole country travels. Book trains, buses, flights and rooms for roughly 11–16 April as early as you can. The rest of the month is much easier.
