Description
Although May is the start of the rainy season in some regions, it remains a great time to visit Thailand, especially the Gulf of Thailand islands like Koh Samui, Koh Phangan, and Koh Tao, where the weather is sunny and dry. Bangkok hosts the Royal Ploughing Ceremony, a traditional event marking the beginning of the rice planting season. Travelers can also enjoy fewer crowds in Chiang Mai and Phuket, making it a good time for sightseeing, snorkeling, and island hopping before the heavier monsoon rains arrive in June.
