Best Time to Visit Thailand

Thailand remains tropical and humid for most of the year and overall the best time to visit is between November and February when temperatures are more manageable and rain is less common. There are three main seasons, the cool season (mentioned above) when temperatures in the North are lower for longer, the rainy season from May to October when warm humid air brought from the Indian Ocean causes the south to be wettest (low season and when fewer tourists travel) and the hot season from March to May. There are of course regional variations across the country, however generally there is little difference in temperature across the center and the south of the country, related to its proximity to the equator.

Our Experts Say...

"Thailand is a top travel destination for a reason. Between the fantastic food, beautiful blue waters, and rich culture the land of smiles is pure magic. When looking at the best time to plan a vacation to Thailand it is important to understand the weather patterns. If culture, countryside, and the angelic city of Chiang Mai in Northern Thailand are calling to you, visiting between November through March will give you cooler and dry weather. The rainy season in Northern Thailand is between June and October which, although can be a bit wet, will create a lush and green climate, and better prices. Moving onto the pulse of city life in Thailand, Bangkok is a city that never sleeps. The coolest season in Bangkok is going to be between November through February. The tropical weather in Bangkok causes humidity and a little rain throughout the year, with the wettest month being June through October. "

"The beaches have two distinct weather patterns. When one is rainy the other is usually dry, creating a year-round beach retreat for Thailand. First up is Phuket and its surrounding areas including Kao Lak and Yao Noi. The weather in this region area follows Northern Thailand and Bangkok quite similarly with November through April being the best times to visit while the rainy season takes place June through October. The east coast of Thailand, including the beautiful Koh Samui, experiences it's dry weather and sunny skies from December through August. The rainfall in Koh Samui falls between September to November. Again, because Thailand experiences tropical weather an occasional hour of rain in the afternoon can be expected year-round."
