❄️ Cool and Dry Season (November to February)
The period from November to February is widely considered the best time to visit Thailand. During these months, the weather is mostly dry, temperatures are comfortable and humidity levels are lower compared to the rest of the year. This makes it ideal for sightseeing, beach holidays, outdoor adventures and cultural exploration.
- Weather: Pleasant daytime temperatures ranging roughly between 20°C and 30°C.
