What people love about Thailand Tours in May
- Bangkok to Chiang Mai Express
Our tour guide Joey was amazing! So thoughtful and made sure we were all ok and happy. We stayed in a hotel in the river which was lovely and got a Thai massage in another hotel in Chiang Mei. We attended an amazing cooking class also
- Amazing Thailand Discovery in 12 Days
Easiest tour group I’ve been with. They get where you need to go with no worry. Highly recommended.
For me the Thai intro tour was a last minute decision - but it was the best decision I have ever made. I have made life long friendships, completed so much off of my bucket list and made unforgettable memories that words can’t come close to explaining. My favourite day was the half day boat trip where we boarded 2 speed boats and cruised around the postcard perfect seas of Thailand. We snorkelled with fishes, bathed on beaches and visited the monkeys on their home island. I can’t imagine there being better group leaders than Adam and Jack. They were funny, kind, organised and had everything under control the whole time - the tour was absolutely amazing on its own but with them guiding it was a huge bonus. Another group leader called Keeks was equally as wonderful, she made everyone feel 100% welcome and looked out for you like you’d been friends for years. I wish you could feel the memories through this writing but you can’t feel words, you have to experience it to feel it.

What our customers ask about Thailand Tours in May 2026
What are the best islands to visit in Thailand during May?
The eastern Gulf islands provide the most reliable weather conditions during May. Koh Samui Koh Phangan and Koh Tao see less rainfall than their Andaman coast counterparts making them prime destinations. These islands offer clear waters with good visibility for swimming and snorkeling especially at spots like Bottle Beach in Koh Phangan. Accommodations such as the Fern Resort in Mae Hong Son tend to offer competitive rates during this quieter shoulder season period.
Are there any special festivals or events in Thailand during May?
May brings two significant cultural celebrations to Thailand. Visakha Bucha Day honors Buddha's birth enlightenment and death with temple ceremonies across the country. The Royal Plowing Ceremony takes place in Bangkok's Sanam Luang where ancient Brahmin rituals mark the start of rice growing season. Both events give visitors a genuine look into Thai cultural traditions.
How crowded are tourist attractions in Thailand during May?
May falls within Thailand's shoulder season bringing noticeably smaller crowds to major attractions. Visitors can explore landmarks like Bangkok's Grand Palace and Chiang Mai's temples without the peak-season masses. The Century Park Hotel Bangkok and similar properties often have good availability. Recent visitors report being able to explore sites like Wat Rong Khun at a relaxed pace without the usual tourist congestion.
What are the best activities to do in Thailand during May?
The month presents good opportunities for cultural exploration and indoor activities. Early morning visits to temples like Wat Phra Singh work well before the day heats up. Floating markets draw fewer tourists and the Elephant Nature Park in Chiang Mai remains popular. The Sukosol Hotel Bangkok serves as a convenient base for these activities. Afternoon rain showers provide natural breaks for traditional Thai massages or exploring local markets.
What are the best regions to visit in Thailand during May?
Northern Thailand stands out as a prime destination during May. The cities of Chiang Mai and Chiang Rai offer pleasant temperatures and rich cultural experiences. Bangkok's extensive indoor attractions provide options during rain while the eastern Gulf coast sees less rainfall than western shores. Hotels like the Empress Chiang Mai offer strategic locations for exploring the region while providing shelter during occasional showers.
What is the weather like in Thailand during May?
May signals the start of Thailand's rainy season characterized by warm temperatures and periodic afternoon downpours. Bangkok sees average temperatures of 34°C (93°F) while coastal regions like Phuket run slightly cooler at 31°C (88°F). The afternoon rains tend to be brief but intense creating a rhythm to daily activities. The moisture keeps the landscape green and helps moderate the temperatures.
