Thailand Weather and Climate

General & Geography

According to COUNTRYAAH, the Kingdom of Thailand is a popular vacation destination in Southeast Asia. The capital and largest city of the country is Bangkok with around 8.4 million inhabitants.

Thailand borders on the neighboring states of Malaysia, Laos, Myanmar and Cambodia. The two adjoining seas are the Gulf of Thailand (Pacific Ocean) and the Andaman Sea (Indian Ocean).

More than 90 percent of the Thai population of currently around 68 million people profess Buddhism.

The national territory of Thailand extends from the southeastern foothills of the Himalayan Mountains to the Malay Peninsula. The center of the country with the capital Bangkok is dominated by the fertile Chao Phraya River.

In northern Thailand (e.g. Chiang Mai and Chiang Rai) are dominated by mountain ranges; Doi Inthanon is also the highest point in the country (2565 meters).

The East Thailand region includes Pattaya and the islands of Koh Chang and Koh Samet. The palm-fringed region of southern Thailand, which includes popular travel destinations such as Phuket, Krabi, Koh Samui, Koh Phi Phi, Koh Pha-ngan and Koh Tao, is of the greatest tourist importance.

Climate in Thailand

The climate in Thailand can generally be described as tropical, but there are regional differences. The north of Thailand has a humid savannah climate, which is monsoonal and makes three different seasons recognizable. The slightly cooler dry season in the north lasts from the beginning of November to the end of February.

Subsequently, the Thai summer runs from the beginning of March to around the end of May with very hot temperatures, before the rainy season in northern Thailand usually ensures heavy rainfall, high humidity and muggy and warm conditions in early June to late October.

The center around the capital Bangkok is climatically part of the tropical savannah zone in the north and is considered to be humid with a longer dry season. The south of Thailand, on the other hand, has more constant temperatures all year round, with only minor fluctuations.

The climate on the popular holiday islands is therefore rather humid and tropical all year round. So there is also tropical rainfall during the northeast monsoon in winter. With the summer southwest monsoons, however, there is a significant increase in humidity and rainfall.

This rainy season in the south runs similar to the north of Thailand from the beginning of June to the end of October. The islands in the southeast (especially Koh Samui) have less rainfall and a shorter rainy season than the areas in the southwest (e.g. Phuket). May, October and November in particular are very humid here.
