If you’re planning a trip to Bangkok, make sure you’re aware of the weather and any events that might take place while you’re there. Bangkok might not have seasons in the same way the non-tropical world does, but some months are still far more enjoyable than others. Extreme heat and humidity and a long rainy season mean that some months are better for visiting Bangkok than others.
When to Go to Bangkok
- The best time to visit Bangkok is between November and February. This is Thailand’s cool season, with daytime temperatures slightly under 30°C and relatively low humidity. This is also Thailand’s peak season for tourism, which means prices are slightly higher overall.
- While November to February might be the best time of year to visit Bangkok, you’ll still have a good time in the city at any other time of year. There’s no “winter” in Bangkok like there is in a cooler country, so you’ll never need to pack a coat.
- Bangkok’s hottest months are from March until late June. In this period, daytime temperatures can reach 35-40°C and humidity can be extremely high. Expect to sweat if you visit during this time of year and pack some cool, comfortable clothing.
- Bangkok’s rainy season lasts from July until October. Although some people expect relentless all-day rain, the rainy season is usually a mix of drab, overcast weather and rainstorms in the late afternoon. When it’s not raining, it’s still easy to enjoy Bangkok’s sights and attractions.
- You’ll get the best value for money by visiting Bangkok during the rainy season, when hotel rooms are marked down significantly. You’ll pay the most to visit Bangkok from November until February, when hotel bookings and prices are at their highest.
- There are several major holidays that take place in Bangkok throughout the year, from the Chinese New Year to Songkran. Read on to find out when Bangkok’s major events occur so you can plan your trip to coincide with or avoid major holiday dates.
