The climate of Thailand can be divided into three types:
• Tropical Savanna climate in the North of Thailand
• Tropical monsoon climate in the South of Thailand
• Tropical Rainforest climate in some smaller parts of Thailand
Savannah climate: In the region where there is the Savannah climate they have relatively dry winters and wet summers. In this climate there are less differences between the seasons compared to the monsoon climate.
Monsoon climate: The monsoon climate, has a long dry period followed by a real rainy season where there are large amounts of rain (almost) daily.
Tropical rainforest climate: Where the Tropical rainforest climate is applicable, there are no real periods of drought. In this region there is a high humidity.
In Thailand, you should always take into account the high temperature. The coolest period is in winter (northern Thailand). Then the temperature at night drops to around 10°C. In higher regions it may even drop to freezing point. During the day the temperature will rise to around 25 to 30°C. Because of continuous high temperature and humidity Thailand feels as clammy and damp. This feeling is of course dependent on the time and location. On average April is the hottest month in Thailand. In May (until approximately September - October) begins in almost all of Thailand the rainseason. In the northeast this season falls between October and January.
During the rain season it rains almost daily. This means that every year during the monsoon about 2000 mm of rain falls in the southwest, 4000mm on the west coast and in the north approximately 1500mm. The majority of this rain falls in the afternoon and in the evening. This are usually short heavy downpours lasting, in most cases, no longer than 2 hours. At the border of Cambodia (south Thailand), there is a tropical rainforest climate. This results in rain during the entire year with aprox. 3000mm of rain a year.
In the summer Thailand is in many regions very muggy and humid due to the rain season. During this season the numbers of sunshine is around 5 to 6 hours a day and it is quite cloudy. In terms of climate it is best to visit Thailand during the winter. Thailand is in this period in many parts relatively dry and the temperatures are not too high. Thailand is not at its best during this period. Many crops will have dried out which give Thailand a dry and brown impression. Want to see a beautiful green Thailand then the period immediately after or at the beginning of the rain season is a better option. Every now and then you will then be surprised by rain.
From February and on the temperature rises steadily and peaks in April. Thailand is ideal for a holiday in the sun during the winter months. In particular, the islands in the south of Thailand are very suitable for this type of holiday. However, a few islands in the Gulf of Thailand have from reasonable to a lot of rainfall during these months. Especially Koh Samui and Koh Phangan. In December and January also these islands have less rainfall.
During your stay in Thailand, it is important to have proper protection against the sun. The sun is already very powerfull immediatly after sunrise, which increases the changes of sunburns. At noon the sun is at its strongest. Therefore, around this time, it is wise to avoid the sun and try to stay in the shadow.
Thailand is located in a region with a lot of hurricane activity (highest in the world). Although Thailand is in this region, the country seldom gets hit by a hurrican. In many cases, the hurricanes pass Thailand and head to the Philippines, China and Japan. In 2004 Thailand was hit by a tsunami, that unfortunately took many lives and left an enormous damage. It is difficult to predict when this natural phenomenon occurs. It is after the disaster of 2004, a tsunami warning system was installed which detects tsunamis and alarm the region. This system is installed for all destinations in the region.
