Thailand has a tropical climate characterized by three main seasons: hot  (March to May), rainy (June to October), and cool (November to February). The country’s climate can vary greatly depending on the region. Let IDC Travel help you understand more about these variations to plan your ideal beach holiday in Thailand! 

In northern Thailand, temperatures tend to be warm to hot for most of the year, except for winter, when the temperature drops slightly at night. In contrast, Bangkok and the eastern Thai coast experience warm to hot temperatures during the winter months, making them ideal for beach enjoyers.

In the spring, temperatures rise, and the heat becomes more intense. Summer and the first half of autumn are typically marked by rainfall, with temperatures slightly lower. The west coast of Thailand, also known as Peninsular Thailand, is hot for most of the year, but the rainy season occurs at different times depending on the location.

Interestingly, the eastern part of the peninsula, which faces the Gulf of Thailand, tends to experience more rainfall during the winter months, while the western side, which faces the Andaman Sea, is the opposite. This unique regional variation is just one of the many factors that make Thailand’s climate so fascinating.
