What people love about Thailand Tours in May
- Thai Intro 9 Day
I have had the most AMZING time ever!!! Being a solo traveller, ThaIntro has been the best thing to do to make new friends and explore places that i may have never gone to. I will remember this trip for ever!! Will definately recommend it to friends, family and everyone i meet. Thanks Tom for an awesome time and looking after us xxxx
- Thai Intro 12 Day
Handy, safe and a social way for starting travelling in Thailand! ThaIntro was well organized and offered lots of experiences, for example from temple visits to thai food cooking class, travelling with night train, relaxing in lovely serene Khao Sok national park, enjoying beaches in Koh Phangan and even meeting elephants! There was also quite a lot party life available for those interested in joining, although our tour happened to end just before famous Full moon party next day after it, so maybe there were more party oriented people in our group than in some other tour. Accommodations were very good. I also joined add-on package to Phi Phi islands for 3 nights, whichwas also nice. Compared to ThaIntro it was very independent travelling by ourselves, but handy as we had nice accommodation and interesting tours booked for us. Sleepaboard experience for staying overnight in Maya Bay was great!
- Thailand Experience
We went on on the 8 day Thailand experience with Ewan and it was everything we expected and more! Right from the outset it felt different than other tours with Ewan giving us great guidance without telling everywhere exactly what to do. There was always options which is essential with a large group with different opinions. Whether you're partying in Bangkok or Koh phangan or chilling in a tube on the lake, some of the things you see on this trip are beyond words! You really do get a true backpacking experience whilst feeling comfortable that your guide knows what's going on. Ewan always went that extra mile to keep the group happy and safe, whether it was carrying people's luggage, going out looking for people who've wandered off, or coming up with extra activities for the group outside of the itinerary that he thinks they might enjoy. More than that he became a great mate and not only would I go on another tour with him, I'll also be popping back to grab another strawberry daquiri with him! Cheers for a great tour dude! ✌
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.
