Thailand weather in April

Wondering about the weather in Thailand in April? Read on for a run-down of everything you need to know. Here we cover everything from average air and sea temperatures, to what to expect in terms of costs and crowds, and what to wear. In addition, we share inspired itinerary suggestions that’ll help you make the most of your trip.

Is April a good time to visit Thailand?

April is a tantalising opportunity to experience Thailand, but at the same time, this month offers a mixed experience. On the one hand, it is the month of Songkran, the Thai New Year, which is celebrated with traditional customs and colourful processions. This cultural extravaganza offers a unique window into Thai traditions and should not be missed.

However, you should be prepared for tropical heat, especially in the northern and central regions, where temperatures can reach levels that may be uncomfortable for some travellers. The country also sees a surge in tourist numbers during Songkran, resulting in overcrowded tourist spots and higher accommodation and transport prices.

Overall, April can be a great time to visit Thailand if you want to experience the cultural splendour of Songkran and aren't afraid of the heat and crowds of tourists. For those looking for a more relaxed and comfortable holiday, other months may be worth considering.

What about the crowd & cost?

April is the peak tourist season in Thailand, associated with good weather and the famous Songkran festival. This means that large crowds can be expected in popular tourist destinations, especially in cities such as Bangkok and hotspots such as Phuket, Krabi and Chiang Mai. Accommodation and flight prices are usually higher during this period due to the increased demand.

Songkran, the Thai New Year, is one of the highlights of April. It is a nationwide water festival celebrated with water fights, traditional ceremonies and lively street festivities. 

While Songkran is an incredible cultural experience, it's important to note that this holiday can be quite stormy and wet, so be prepared to partake in a water-soaked celebration if you find yourself in Thailand during this time. If you prefer a more relaxed and budget-friendly holiday, you may want to read all about the weather in Thailand in March.

What to wear in Thailand in April?

The weather in Thailand in April is quite hot, so the right choice of clothing is essential for a comfortable trip. Choose light, breathable cotton or linen clothing and protect yourself from the intense sun with sunglasses, a wide-brimmed hat and sunscreen. If you plan to visit the beach or pool, don't forget swimwear. Comfortable sandals or flip-flops are ideal for walking in the heat. 

Remember that when visiting temples, you should have clothing that covers your shoulders, arms and knees, as well as a scarf or shawl for extra protection. Don't forget insect repellent and a reusable water bottle to stay hydrated. Also, remember that it's not uncommon to get wet during Songkran, so bring a change of clothes or a waterproof bag for valuables.
