Thailand in April: Weather & Where to Visit

Thailand in April: Weather & Where to Visit

By Chris QuanUpdated Oct. 19, 2021

April is the height of summer in Thailand with temperatures across the country soaring above 30ºC (86ºF). Regardless of where you head on your vacation, there is no escaping the blistering heat.

Luckily, Thailand is well equipped to deal with hot weather with air-conditioned shopping malls, restaurants, taxis, and hotel rooms across the country.

In this article, we are going to take a look at the weather conditions and the six best places to visit in Thailand in April. 

Average Weather in April

Location Min. Temp. (ºC) Max. Temp. (ºC)  Rainfall (mm) Min. Temp. (ºF) Max. Temp. (ºF)  Rainfall (in)
Bangkok 25 35 72 77 95 3
Chiang Mai 22 36 45 72 97 2
Phuket 24 34 157 75 93 6
Krabi 25 34 120 77 93 5
Hua Hin 25 33 35 77 93 1
Koh Samui 26 32 86 79 91 3

Central Thailand

The daily temperatures in Thailand"s capital city and the rest of Central Thailand regularly hit 38, 39, and even 40ºC (100–104ºF) throughout April.

Daytime outdoor sightseeing is not recommended for the elderly or anyone with underlying health issues. The saving grace for Bangkok is that it"s well prepared for the summer months.

If you are sensible and stick to early morning and evening walks and head to the many air-conditioned venues in the city, you can still have a fantastic time in Bangkok in April.

Northern Thailand

The heat in Chiang Mai during April gets even more oppressive than in Bangkok, with temperatures exceeding 36ºC (97ºF) almost daily.

It"s not ideal weather to walk around the city"s temples by foot but, as with Bangkok, there are plenty of air-conditioned coffee shops, malls, and restaurants to cool down in.

Chiang Rai is slightly cooler by a degree or two but is still hot nonetheless.

Southern Thailand

Whichever side you choose, the Gulf or the Andaman, you are almost guaranteed some blue skies and clear seas.

While the daily average temperatures in Southern Thailand range from 33–35ºC (91–95ºF) in April, if you are at one of the beach resorts, it feels at least 4 or 5 degrees cooler than in Bangkok or Chiang Mai.

You may experience some rain in the south but it will most likely come in the form of isolated showers, which happen mostly at night, so it shouldn"t have much effect on your overall vacation.

Why Visit Thailand in April?

If you can handle the heat, April is a fantastic time to visit Thailand, especially one of the beach destinations in the south. You are almost guaranteed to have clear blue skies and calm seas, even if you do get the odd rain shower toward the end of the month.

However, April in Thailand is all about the Songkran festival, which is Thailand"s New Year celebration. From April 13th to 15th, Thailand descends into one big water fight with seemingly the whole country taking to the streets armed with water guns and buckets ready to soak whoever they see. It"s a party like no other and one you"ll never forget.

6 Best Places to Celebrate Songkran in Thailand

1. Bangkok

Between the 13th and 15th, the capital city sees thousands of tourists and locals joining in the biggest water fight in the country for Thai New Year.

Getting a bucket of ice-cold water poured over you can be surprisingly refreshing given the extreme temperatures around the time of the festival.

The two main places in the city to celebrate Songkran are Khao San Road, which is the backpacker area, and Silom, the business district.

Both areas are closed off to vehicles and turned into giant party zones with loud pumping music, lively crowds, and plenty of water. It"s a fun experience and definitely something you should see, even if from afar.

One day is more than enough to celebrate Songkran, in our opinion, and anything more than that becomes a bit of an annoyance.

If crowds, loud music, and traffic are not your thing, we would suggest skipping Bangkok between the 13th and 15th as it"s almost impossible to escape the madness of Songkran.

2. Chiang Mai

Chiang Mai Chiang Mai

Chiang Mai is one of the most popular cities to visit in Thailand and also has one of the most prolonged and most enjoyable celebrations of Songkran in the country.

Lasting between 3 and 5 days, it"s quite remarkable to see how much energy the local people have, getting up every day and celebrating from morning until night. Chiang Mai is the place to celebrate Songkran in Northern Thailand.

The biggest celebrations and water fights take place at Tha Phae Gate and the big malls, such as the Central Kad Suan Kaew and MAYA malls.

There are also traditional processions in the city for Songkran along with events like the Miss Songkran Beauty Pageant. The area around the Three Kings Monument in the Old City has a Songkran parade on Charoen Muang Road in which a Buddha statue is carried through the street. Locals line the street to give praise and pray for good luck for the new year.

3. Phuket

Phuket Phuket

The ideal time to visit Phuket is between November and April when water conditions are suitable for activities such as swimming, snorkeling, and boating.

Toward the end of April, you may experience some rain showers and storms but these generally occur at night so shouldn"t have much of a negative impact on your vacation.

Phuket is Thailand"s biggest and most popular island and is one of the best places to experience Songkran. The festival can last for up to a week in Phuket and the major tourist destinations along the beaches turn into party central, especially in Patong.

4. Khao Lak

With its close proximity to Phuket, temperatures in Khao Lak during April are identical — hot and humid. During April, temperatures can soar up to highs of 35ºC (95ºF) so it"s best to avoid the hottest parts of the day to lower your risk of heatstroke or sunburn.

Luckily, Khao Lak boasts some of the best beachfront resorts in the country with most having at least one swimming pool to cool down in.

Khao Lak is an excellent alternative to Phuket if you like a more laid-back atmosphere, especially during the Songkran celebrations.

It"s a laid-back affair in this small town where Thai families and friends gather on the sides of the streets with buckets of water and water pistols to catch any passersby they can.

5. Krabi

Krabi"s daily temperatures hover around 34ºC (93ºF) but can feel much cooler when you are close to the sea breeze. Railay Beach is situated in a bay of the same name and the giant limestone cliffs that surround it can offer some shady respite from the day"s oppressive sun. The beach is so unique that it has consistently been voted in the top 10 beaches in Thailand for the last decade.

Phra Nang Cave, which connects east and west Railay, is considered to be one of the best natural attractions in Thailand with multicolored stalactites and stalagmites running the length of the cave. It takes a total of 15 minutes to walk from beach to beach and is excellent for breaking up your sunbathing sessions.

Krabi"s main tourist town of Ao Nang is the heart of the Songkran celebrations. Things get pretty wild on the main strip with trucks blaring music and hundreds of locals and tourists lining the main drag to participate in the area"s biggest party and water fight.

6. Koh Samui

Koh Samui, Thailand Koh Samui, Thailand

The weather in Koh Samui in April is so blisteringly hot that the Songkran soaking you will receive across the island will come as a welcome relief.

The daily average of 32ºC (90ºF) and minimal rainfall make Koh Samui a beach dweller"s dream in April. The water visibility is fantastic throughout this period, giving scuba divers and snorkelers a chance to see the area"s exciting and varied sea life at its finest.

Several other events take place on the island in April, such as the LGBT Pride Festival and the Koh Samui Triathlon, so there is plenty to see and do in Koh Samui throughout the month.
