Check the live forecast above for your destination before travelling, as Thailand’s tropical climate varies significantly by region and season, with the southwest monsoon bringing heavy rain to most areas from May to October.
What is the weather like in Thailand year round?
Thailand has a tropical monsoon climate, meaning it is hot and humid year-round with three distinct seasons. The cool season (November to February) offers the most comfortable conditions, while the hot season (March to May) can be oppressively warm, and the rainy season (June to October) brings frequent downpours, especially in the north and along the Andaman coast.
- Southern Gulf coast (Koh Samui, Phuket) has a different rhythm; it sees its heaviest rain from October to December.
- Northern Thailand (Chiang Mai) can experience smoky haze from agricultural burning from February to April.
- Sea temperatures are warm enough for swimming year-round, typically 27–30°C.
- Thailand weather by month shows April as the hottest nationally, with average highs of 35°C in Bangkok.
