Thailand has a humid tropical climate and it is always hot; and very important:
A trip to Thailand can be enjoyed at any time of the year
However, three seasons can be distinguished:
Cool Season
November to February
The most pleasant temperatures and less probability of precipitation; therefore, the favorite of travelers and the one that corresponds to the high season in terms of tourism.
Summer
March to April
The season with the highest temperatures of the year. It’s mostly hot almost everywhere. On the other hand, the amazing Songkran festival starts on 13h April.
Rainy season
May to October
Temperatures drop compared to previous months but rain comes strong. Rainfall is usually short and intense, so it’s not the end of the world. Some marine national parks are closed.
When is the best time to visit Thailand?
Quick answer: Best time is from November to February
The best time to come to Thailand would be from November to February since it is when it rains less and is less hot, however, there are more tourists. If you cannot come at this time, don’t worry, in reality it also has its advantages to come during low tourist season: prices are cheaper, more accommodation is available, it is easier to find train tickets, there are offers and discounts, etc.
When is it the rainy season in Thailand?
From 1st May to 31st October.
Can I go to Thailand during the rainy season?
Quick answer: Of course, it’s not that bad
Traveling in Thailand in the rainy or monsoon season doesn’t have to be a problem. The rainy season is very unpredictable, and even if it rains, it rarely does it all day, if not it rains a couple of hours very hard, usually in the afternoon-night and then stops.
Thailand during the rainy season has some advantages: less tourist, cheaper hotels and cooler temperatures than in March or April
If you come to Thailand in August, don’t worry too much about the weather and go wherever you want. In the south, where are the beach destinations, when it rains on the East coast it does not usually do so on the West coast, so you can always enjoy a beautiful beach without problems.

During March and April in Thailand it’s still high season but not peak season, so prices of the hotels are on a medium range. Not as expensive as in December or January but not as cheap as May to October.
From 13th to 15th of April Thailand celebrates its new year, the Songkran Festival which is very interesting to experience.
