Today's briefing

Bangkok is looking toasty at 29 degrees right now but it'll feel closer to 34 with the humidity, and we're expecting a wet day ahead with a 92 percent chance of rain and a very high UV index of 8. Today's high will reach 31 degrees, so keep an umbrella handy but don't leave the sunscreen behind either. Grab a light, breathable shirt that dries quickly—you'll want something practical for the rain and heat combo that's coming our way. Come the weekend, Saturday's looking a touch drier at 49 percent rain chance with a high of 32, but Sunday will turn properly soggy again with 92 percent rain and a high of 31.

Bangkok weather, explained

How to read the Bangkok forecast

A good forecast is really three views at once. The current panel tells you what it feels like outside right now, which is what matters before you head out the door. The hourly strip is for planning the next part of your day: when the rain band arrives, when the wind picks up, when the heat eases enough for a walk. The seven-day outlook is for the week ahead, and it is most reliable in the first three or four days. Read it from the top down and you will almost always have what you need for Bangkok.

How the monsoons shape Bangkok

Bangkok has a tropical monsoon climate driven by two seasonal wind reversals. From roughly May to October the southwest monsoon carries warm, moisture-laden air off the Indian Ocean and Andaman Sea, producing the wet season: high humidity, towering afternoon build-ups and short, intense thunderstorms that can flood streets within an hour. From November to February the drier northeast monsoon brings the cool season, with lower humidity and the most comfortable days of the year. In between, March to May is the hot season, when temperatures climb into the high 30s before the rains return. The city sits low and flat on the Chao Phraya river delta near the Gulf of Thailand, so humidity stays high year-round and drainage matters as much as rainfall totals.

What the UV index means in Bangkok

Bangkok sits near 13.8 degrees north, close to the tropics, which puts the sun almost directly overhead for much of the year. UV is intense here: the index regularly reaches 11 or above (the 'extreme' band) around midday, even in the cooler months, and skin can burn in under ten minutes at that level. UV peaks at solar noon, not at the hottest part of the afternoon, so checking the number rather than judging by the temperature is the most reliable habit. Below 3 is low and you can be outside without extra protection. From 3 to 7 means sunscreen earns its keep. Above 8 means a hat, sunscreen and shade are all genuinely useful, not optional.
