What to know before you go to Thailand in April

Thailand in April is loud, hot, and completely unbothered by your plans to stay dry. The sun’s out, the humidity’s high, and the country throws its biggest party of the year right in the middle of it all. Songkran takes over the streets with water fights, parades, and public holidays, so expect price jumps and packed hotels. Still, outside the splash zones, you’ll find beach towns with breezy evenings, national parks before the rains hit, and a cheeky deal or two if you dodge the hot spots.

Is April a good time to visit Thailand?

April works well for travellers chasing festivals and beach escapes, but the intense heat requires some planning. If you're heading to Thailand for Songkran’s water fights and cultural celebrations, mid-April is unbeatable. 

Southern islands like Phuket and Koh Samui enjoy calmer seas before the monsoon hits, which makes it perfect for snorkelling and island-hopping. Northern cities like Chiang Mai get oppressively hot, sometimes with haze from agricultural burning, though the heat eases by evening. 

Families with young kids might struggle with temperatures often exceeding 35°C inland, so coastal areas offer breezier relief. April attracts moderate crowds outside Songkran week, giving you breathing room at popular temples and beaches. Plan the indoor activities for midday and save outdoor adventures for early morning or late afternoon.

Is April a cheap or expensive time to visit Thailand?

April sits in shoulder season territory, keeping costs lower than Thailand's peak months from November to February. You'll find better availability for flights and hotels, with prices dropping outside Songkran week. 

Saying that, accommodation and transport costs spike during the festival (13 - 15 April), particularly in Bangkok and Chiang Mai, where celebrations are biggest. Book early if you're planning to be there for the water fights. Outside those few days, you can expect solid deals on beachside resorts and city hotels as Thailand prepares for the quiet season ahead.

Weather in Thailand in April

Expect scorching conditions with daytime highs hitting 30 - 36°C nationwide, cooling slightly to 25 - 28°C at night. Humidity hovers around 70 - 80%, making it feel sticky and uncomfortable at times. Rainfall totals 40 - 80mm over 5 - 8 days, mostly arriving as short tropical showers or afternoon thunderstorms rather than all-day rain. 

Sunshine averages 8 - 9 hours daily, brilliant for beach days but brutal during midday. Sea temperatures sit at a comfortable 29°C, perfect for swimming and water sports. Southern islands see rising rain chances late in the month as monsoon season approaches, whilst northern and central regions stay drier but hotter.

Where to go in Thailand in April

Koh Samui, Phuket, and Krabi: Southern islands provide calmer seas and lower rain risks, ideal for beachgoers seeking clear waters and dry conditions before the monsoon season arrives.
