October marks the transition from Thailand's rainy season to the cool and dry season. While showers are still common early in the month, rainfall gradually decreases as October progresses. Temperatures stay warm between 24°C and 31°C, and the countryside looks lush and green after the monsoon. With fewer tourists and better hotel deals, October is a great time to explore Thailand before peak season begins.
