Bangkok Weather Guide

Despite being divided into hot, wet and cool seasons, Bangkok is really hot all year round with rain ranging from torrential to summer storms. So, whenever you decide to travel to Bangkok, just make sure your accommodation has air-conditioning and you've packed shoes you don't mind getting wet!

Season and Clothing

Cool Season: November to February

Bangkok's cool season is also high season when days are mostly sunny, clear and rain free, however, afternoon thunderstorms are common and nights are balmy. The cool season is regarded as the best time to visit the Thai capital with travellers heading to the city to celebrate the Western New Year as well as Chinese New Year, which both feature an array of festivities including spectacular fireworks displays. On New Year's Day it's customary for Buddhist Thais to make merit at shrines and wats.

Average temperatures: 21 - 31 degrees Celsius.
Appropriate clothing: Summer dresses, shorts and tees in lightweight fabrics.
Don't forget: Thongs or sandals, sunscreen, a hat and sunnies.

Hot Season: March to June

The hot season in Bangkok is when the mercury averages a very warm and humid 29 degrees Celsius. March can be windy and April is by far the hottest month.To put it mildly, it's not pleasant and you're bound to spend much of your time indoors in air-conditioning. You may want to come outside in April for Songkran though. The Thai New Year festival is a fun time to be in Bangkok with much of the city shutting down and locals taking to the streets for a water fight with buckets of water providing much relief from the heat. 

Average temperatures: 25- 33 degrees Celsius.
Appropriate clothing: Summer dresses, shorts and tees in lightweight fabrics, sandals.
Don't forget: Your cossie for the Songkran water fight.

Wet Season: July to October

Bangkok in the rainy or wet season is when the southwest monsoon arrives. During this time, temperatures still remain warm with an average of 28 degrees Celsius but days are shorter and experience torrential downpours with gentler rainfall in the evenings. On average, August and September are the wettest months in Bangkok with floods common in various parts of the city. If you don't mind spending most of your Bangkok holiday indoors (ahem, shopping), the wet season could be the best time to travel with accommodation prices much lower than the other seasons.

Average temperatures: 24 - 32 degrees Celsius.
Appropriate clothing: Shorts, tees, dresses and a rain poncho.
Don't forget: An umbrella and shoes that you don't mind getting wet.
