Our guests always ask us, "what is the best time to visit Bangkok?" The answer varies a bit depending on what you're looking to do in Bangkok, so we have put together some advice below so you can plan the perfect time to visit Bangkok.

Bangkok enjoys a tropical monsoon climate, meaning that it has three main seasons: the hot season from March to June, the rainy season from July to October, and the cool season between November and February. In one of the hottest cities in the world, expect daytime temperatures to be over 30°C for most of the year. An exception to this is when you visit in late December and early January, so the best time to go to Bangkok is completely dependent on your plans for your vacation.

The two periods – April to May and September to October – are when Bangkok is at its most humid. The southwestern monsoons arrive between May and October, bringing unsettled, cloudy skies. For many people, this is a welcome respite, though flash floods often occur in the outskirts and low areas of the city. Whether you’re going sightseeing or want to take some of the best tours in Bangkok, it’s important to decide the best time to visit Bangkok for your trip.
