This article covers the weather in May in Thailand, including average temperatures, rainfall, and tips on what to wear and places to go.
Thailand Weather in May Overview
- Average temperature range: 29–35°C (84–95°F)
- Rainfall: 84 mm (10 inches)
- Rainy days: 25
- Sunny days: 5
As one of the hottest months in Thailand, the temperature in many places of Thailand can reach 35°C (95°F) on average daily. With an average of 16 rainy days, Thailand is quite wet during May. Sometimes, it rains cats and dogs in some places. So, remember to take an umbrella and waterproof jackets.
Thailand's Regional Weather
|Location||Min. Temp. (ºC)||Max. Temp. (ºC)||Rainfall (mm)|
Bangkok and Central Thailand: May gets extremely humid as the hot season gives way to the wet season. The rainfall starts to increase toward the end of the month with more than half of the month seeing short, thunderous bursts that last for about an hour.
Southern Thailand: Rainfall during May is much lower on the Gulf of Thailand than on the Andaman Coast. The Andaman Coast, where Phuket and Krabi are situated, starts to see the effects of the southwest monsoon, which begins in late May, but it isn't in full swing until June.
Seeing Bangkok with ease
In Bangkok, our tour guide, Ying, was wonderful. She navigated all the sights with ease, gave us interesting tidbits on Thai culture and history, helped us pick the right food at all the restaurants, and was just a pleasure to be around. We had a great time, and it was so nice to not have to worry about any of the details.More

Asia Highlights and Sharon
Asia Highlights, specifically Sharon, has been wonderfully helpful as we get ready for a 2024 excursion to Thailand.

Thailand, Singapore, Bali
In Thailand, Tanny and Nori(Suparp), were both incredible! They were both fun, funny, and full of knowledge and made sure we got the full experience. They went the extra mile and always made sure we had cold bottled water and towels to cleanse our hands. In Singapore, Nicole was an absolute gem. She was so kind and knowledgeable and guided us in the right direction to make our day as enjoyable as possible. She helped us choose a top notch local lunch and coffee spot in China Town and taught us so much about the country! In Bali, Emon was an absolute joy. He was very knowledgeable and kind and absolutely made sure we were feeling comfortable and was willing to be flexible with us. He was fun to converse with and made our time traveling between destinations so enjoyable! I cannot recommend Asia Highlights enough! Accommodations, travel arrangements and guided tours were all a breeze.More

Large multi-generational holiday in Thailand
The holiday was wonderful. Our guides, Mr Monchai (Bangkok), and Ms Tipagorn (Tippy) (Chiang Mai) were exceptional. Travelling in a large multigenerational group with many children requires patience and our guides truly understood that. Mr Monchai and Ms Tippy shared their extensive knowledge of the many wonderful places we visited, and were flexible to take us to additional places along the way based on discussions. While everyday was busy, having them greet us with patience and a smile truly made this a memorable holiday. The hotels we stayed at were equally wonderful and went above and beyond to celebrate not only my parents 50th anniversary but also celebrate 2 milestone birthdays that occurred. We will cherish this holiday for many years to come. We hope to use Asia Highlights again.More

The Best Places to Visit in Thailand in May
May is one of the hottest months in Thailand. We are selecting some suitable place in May for you. Read more about the best places to visit in Thailand in May.
Although it is quite hot during May, Bangkok is a must-visit city if you are traveling to Thailand. There are numerous historical attractions that are worth visiting including the famous Grand Palace, Bangkok National Museum, which is a mecca for Thai history and art, and Jim Thompson House Museum, a beautifully designed Sukhothai wooden house set in the heart of Bangkok's shopping district.
2. Chiang Mai
Located in the mountainous north, Chiang Mai is a good place for trekking among the greenery and villages and climbing some of the tallest mountains in Thailand or just visiting the elephant sanctuaries. Tourists can also take cooking classes and spa treatments, neither of which are weather dependent.
3. Chiang Rai
You can escape the heat and humidity during May in Chiang Rai by visiting the Huai Kaew and Huai Mae Sai waterfalls to cool down.
There are also numerous air-conditioned cafés and restaurants in town where you can grab a traditional iced tea or an authentic Lanna meal when the heat gets too much to handle.
As the rainfall starts to increase toward the end of the month, the already stunning Chiang Rai valleys and mountain ranges get greener and even more beautiful than before.
4. Hua Hin
Of all the mainland beach resort towns, Hua Hin has least rainfall and is a great place to spend your vacation in May. It's close enough to Bangkok that you don't have to fly and has a range of beaches and resorts to suit any taste.
5. Koh Samui
Koh Samui, along Thailand's Gulf Coast, does not see the full effect of the southwest monsoon until September, which makes May a great month to visit the island.
With the deteriorating weather comes less than ideal snorkeling and diving conditions. While diving is still possible on the sheltered east coast, it becomes far less practical on the west coast.
Although it is hot and often rains in May, you can still enjoy the beaches in late afternoon or early morning when the temperature is not unbearable. Phuket and Krabi sometimes experience torrential downpours and strong winds, meaning some boat services to other islands can be suspended.
Crowding and Costs in May
Due to its extreme heat and humidity, few people choose May to visit Thailand. Hotel and attraction rates are quite low during May. If you are looking for discounted tours in Thailand, May is a good time to save money for traveling.
Clothes to Wear in May
As one of the hottest months in Thailand, light and cool clothing is most comfortable to wear in May, including shorts, skirts, T-shirts, light trousers, and caps. It often rains in May, so umbrellas, light raincoats, rubber boots or sandals are needed from time to time.
If you are going to visit temples in Thailand, remember to wear long-sleeved clothes, and long skirts or trousers out of respect.
