Thailand can be visited year-round, though weather varies by region. November to February is the best time to go — cool, dry, and sunny nationwide, with the famous Loy Krathong and Yi Peng festivals. March to May is hot and sunny with little rain, and April gets lively with Songkran. June to October is the rainy season, bringing higher humidity and tropical showers. Note the Gulf side (Koh Samui, Koh Phangan, Koh Tao) differs slightly: dry with calm seas from February to July, wetter and rougher from August to December.
