Thailand's best travel time is from November to mid-April - taking into account regional variations.
In our winter, the weather in Thailand is warm and dry. When it shows us the summer, there is rainy season in Thailand. However, it should also be remembered that in the main season, the prices for accommodation rise sharply.
As the islands very often have their own microclimate, other travel times may apply to them and are discussed in detail here.
Take your time and read our extensive information on the recommended Thailand travel time, so that your Thailand tour does not fall into the water!
Rainy season in Thailand (June to October) does not mean that it rains like us permanently during the day. A tropical rain shower usually lasts only 30 minutes. However, you can fully enjoy the bathing holiday in the school holidays July / August only in the Koh Samui archipelago.
On the west coast of Thailand, the Andaman Sea, the monsoon rains between May and October, and swimming during the rainy season can be partly inedible - even dangerous! Trekking tours in the north, however, are a treat! Rich green rice fields and lush vegetation are in full glory
Thailand has two distinct climates: a tropical savanna climate in the northern part of the country and a tropical monsoon climate in the south and southeast. There are three seasons: the so-called "cool" season (November to February) with temperatures between 21 and 30 degrees, the hot season (March to the end of May) with average temperatures around 30 degrees and the rainy season (June to October) in which Sunshine alternated with short, heavy rain showers. The thermometer still remains at 32 degrees. (In the shade!)
The water temperatures are a maximum of 5 degrees lower. For families with schoolchildren - who have to "experience" Thailand in August - swimming in the monsoon season is only safe on Koh Samui, Koh Phangan and Koh Tao. The most pleasant climate especially for the elderly is between November and February. Thus, this is also the best travel time Thailand.
Summer time from March to the end of May. At this time begins a heat period that makes traveling to the areas of Bangkok and north of it sometimes cumbersome - sultry, hot 40 degrees. The summer remains mostly dry and brings high temperatures and humidity of 80-90%. Pleasant weather then prevails especially in higher mountain regions or in the traditional seaside resorts on the coast.
The "green season" from early June to late October. The rainy season can vary from region to region. In the Andaman Sea, most of the precipitation comes down from September to November, in the Gulf of Siam from October to December. Mostly it rains in the afternoon for one to two hours very strong, then the sun is shining again and the short cooling is quickly forgotten. Especially for nature lovers Thailand is recommended for the rainy season, because now everywhere lush vegetation prevails and all over Thailand in the lush green shines.
In the north, the rainy season usually begins at the end of June, and in the northeast, it is already over at the end of September. From May to August you can travel the north, northeast, central Thailand and the coast on the Gulf of Siam very well. The south is divided into two weather zones at this time. While more rain falls on the west coast, the east coast and the island regions around Koh Samui enjoy the best weather.
Cooler interval from November to February / March. In the north, there may actually be some cooler nights at this time - temperatures in the rest of the country are climbing to between 26 and 30 degrees Celsius. At night, it cools little.
