Thailand in April 2026: What to Prepare for Songkran Festival

2. Thailand Weather in April: What It Really Feels Like

If you're planning a trip to Thailand in April, it's worth knowing that the heat can be pretty intense. Temperatures average around 35°C, and in some regions they can climb to nearly 39°C.

3. Thailand in April by Region

3.1 Bangkok and the central Thailand

If you're heading to Bangkok in April, be ready for some serious heat as we're talking average temperatures around 30°C, often climbing past 35°C.

It gets pretty stifling out there, so trust me, you'll want to pack your lightest clothes and keep a water bottle on you at all times. The occasional shower does help take the edge off, but don't count on it to cool things down for long!

3.2 Chiang Mai & Northern Thailand

In Northern Thailand, April is hot during the day but noticeably cooler at night. In Chiang Mai, temperatures usually drop to around 22°C in the evening and can climb to about 36°C during the day.

Occasional showers may occur, but they are generally brief. I’d recommend bringing a light jacket for the evenings and plenty of sunscreen for the strong daytime sun.

Despite the heat, outdoor activities are still completely manageable if you pace yourself and stay hydrated.

3.3 Northeast Thailand (Isan)

Scorching hot! April is not really the ideal month to visit northeastern Thailand. Although occasional rainfall is possible, I can see that the countryside is generally arid and parched, often turning a dusty brown.

If you really like this area, I’d still suggest visiting Thailand’s “Grand Canyon,” Pha Taem National Park. The nearby Mekong River brings slightly cooler breezes and adds some dramatic riverside scenery, which makes the heat a bit more bearable.

3.4 Gulf Islands (Koh Samui, Koh Phangan, Koh Tao)

On the Gulf islands of Thailand, such as Koh Samui and Koh Phangan, April basically means heat and clear skies. Temperatures hover around 30°C, with plenty of sunshine and very little rain. The seas are generally calm, the sandy beaches look their best, and water activities are in full swing under a bright, radiant sun.

3.5 Andaman Coast (Phuket, Krabi, Khao Lak, Koh Lanta)

On the Andaman coast with Phuket and Krabi, the climate in April is conducive to relaxation. Pleasant temperatures, between 24°C and 34°C on average, as well as a low risk of rain, allow for full enjoyment of the beautiful white sandy beaches and nearby paradisiacal islands. It is the perfect time for swimming, boat trips, and discovering the splendid tropical landscapes.

4. Best Places to Visit in Thailand in April 

4.1 North: Chiang Mai and its surroundings

Between culture, celebration, and great food, Bangkok in April feels lively yet surprisingly relaxed, with plenty of small surprises along the way.

After the joy of the streets, nothing beats a traditional Thai massage to relax. The city then reveals itself in a new light, away from the usual tourists.

Khao Lak is all about absolute tranquility, Koh Lanta is postcard landscapes suitable for swimming and sporting activities. Koh Samui has its share of dream beaches for sunning and lolling, and Krabi has its incredible cliffs and well-kept coves for boating. Koh Phi Phi has an island with life and culture; pounding nightlife and calm zones for relaxing.
