Bangkok is an exciting city full of culture and activities, with something to suit all tastes. January is a great time to visit as the weather is mild and the city is less crowded. We've looked at the most up-to-date weather data for Bangkok, covering the last 12 years up to 2024, plus we've asked our team of travel bloggers for their first-hand experiences in order to answer the most frequently asked questions about Bangkok weather in January.

How hot is it in Bangkok during January?

Expect heat in Bangkok during January. The temperature hits about 33℃ during the day, falling away to a balmy 24℃ at night. The UV index will be high at this time of year, so protection against skin and eye damage is needed. Try to limit exposure between 10am and 4pm. Apply broad spectrum SPF 30+ sunscreen every few hours, even if it's cloudy, or more frequently after sweating or swimming, and wear UV-blocking sunglasses too, and bear in mind that bright surfaces, such as sand and water increase UV exposure.

Does it rain in Bangkok during January?

On average, there will be 2 rainy days during the month, amounting to 30.4mm in total. That's much drier than we see in England during August, and therefore not something to be concerned about. You're not likely to see a thunderstorm during your trip.

Is it windy in Bangkok during January?

You're unlikely to experience any strong winds. Expect a light breeze that picks up slightly at times in January. With moderate humidity, any breeze will have a welcome cooling effect.

How warm is the sea in Bangkok during January?

The water around Bangkok reaches a very pleasant 27℃ during January. This is very warm, and will feel bath-like. People who normally feel the cold will find this temperature perfectly acceptable. The hot air temperature will mean that you will feel comfortably warm when coming out of the water.
