The best time to visit Sukhothai is during the cool and dry season, which runs from November to February.During these months, the weather is most pleasant for exploring the ancient ruins. You can expect clear skies, lower humidity, and average daily temperatures ranging from 20°C to 30°C (68°F to 86°F). This makes walking or cycling through Sukhothai Historical Park very comfortable.The shoulder seasons, March to May (hot season) and September to October (rainy season), can also be suitable for visitors who prefer fewer crowds or are on a budget. During the hot season, temperatures can reach over 35°C (95°F), so early morning or late afternoon explorations are recommended. The rainy season brings occasional downpours, usually in the late afternoon, but the landscape is lush and green.For those planning to attend the Loi Krathong festival, a significant and visually stunning event, you'll want to visit in November.
