Bangkok in August: Honest Thoughts from a Year-Round Resident
If you thought July was wet, well, August in Bangkok says hold my Chang. The monsoon is now officially in full swing — but the plus side of that is that the daytime temperatures are a bit lower, finally!
Admittedly, the rain is more intense. Storms come heavier, which means streets flood faster, which means — potentially! — some deeply unpleasant walks through the sois.
That said, August isn’t a total washout. In fact, in Bangkok, no time of year truly is. As a year-round Bangkokian, I have to say, the city is absolutely livable (and visitable!) this time of year.
In fact, I love being in Bangkok in August. It has several things going for it: fewer tourists, which means shorter lines and better hotel deals, in addition to cooler temperatures and more frequent breaks in the humidity. And honestly, if you don’t mind a tropical downpour or two, you can get quite into the moody monsoon vibes like I do!

- Average highs/lows: ~33 °C / 26 °C (92 °F / 79 °F). source
- Record extremes (observed in recent Augusts): up to 37 °C (Aug 11, 2023) and down to ~25 °C on cooler August nights. source

August is smack-dab in the middle of monsoon season, so while the temps dip a bit more compared to July, the humidity can sometimes be a bit more intense.
What I notice about August in Bangkok is that there are more cloudy days (softer sunlight and less UV index!), but more frequent rainstorms — sometimes multiple in a day, as opposed to one quick storm passing through.
The Honest Truth About Rain in Bangkok in August
While an August Bangkok downpour can be quite moody and unrelenting, all-day washouts are still rare. You’ll definitely still get some sunshine in between the rain.
My personal experience is that roughly every other day, you’ll get intense bursts of rain (think 1-2 hours, sometimes with thunder and lightning) as well as days that often are gray, and occasionally sunny.
It’s unpredictable, yes, but I think it’s rather manageable if you stay flexible and bring some rainy season essentials (shoes that can handle a bit of rain, an umbrella, and a poncho). You’ll be just fine.
Tips for Making the Most of Bangkok in August
- Carry a poncho or umbrella everywhere: The one day you don’t will be the day you get caught in a storm — I don’t make the rules.
- Front-load your days: Mornings are usually drier, so when it comes to making a rainy season day game plan, I tend to save indoor activities like shopping or going to the movies for the afternoons and evenings. I can also more easily shuffle my day’s plans this way, if it happens to rain in the morning instead.
- Trains over taxis: The BTS and MRT stay blissfully unaffected by gridlocked traffic caused by the rain. Also, when it rains, taxi surge prices climb almost as high as the water levels on a flooded soi!
- Don’t fight the rain: Café-hop, get a Thai massage, or just lean into Bangkok’s world-class indoor life (malls, movies, museums galore!)
Weather in the Rest of Thailand in August
This is where it gets tricky. August is one of the rainiest months across much of Thailand, so you won’t find too many places to escape.
However, I recently did a trip to Hua Hin in August and the weather there was gorgeous — so much sun and no rain until we left! It felt hotter than Bangkok due to the sun, but I didn’t mind as it made getting into the ocean that much more pleasant.
- Southern Andaman Coast (Phuket, Krabi, Koh Lanta, Koh Lipe): Rain-heavy, seas can be rough… just ask my stomach, which has definitely been emptied into a stormy August sea before.
- Gulf Islands (Koh Samui, Koh Phangan, Koh Tao): Your best bet if you want beaches with sunny days — though do still expect the occasional thunderstorm.
- Northern Thailand (Chiang Mai, Chiang Rai): Not the best season for travel especially closer to the Laos border, as flash floods can occur more often in Northern Thailand. Be careful if you’re thinking about road/moto trips like the Mae Hong Son Loop, etc.
