Thailand is an Asian country located east of Myanmar (Burma) and north of Malaysia. Thailand's climate is predominantly tropical and humid throughout the year. However, the state is divided into two different climatic zones: the area north of Bangkok generally has three seasons, and the southern peninsular area two. Tourists in Thailand must be prepared for hot, humid weather.
Northern Thailand
North of Bangkok, Thailand is experiencing three seasons. The dry season is divided into two periods: from November to February, when the weather is mostly dry with cool monsoon breezes, and from March to May, when the climate in Thailand is slightly warmer.
From May to November, the area is affected by the southwest monsoons, and precipitation tends to be at its peak during this time, especially in September. Rainfall in this region is about 55 inches annually.
During the cool dry season, the average temperature in Bangkok is 18 degrees Celsius. During the hotter dry season, temperatures rise to about 34 degrees on average. However, for this season, 40 degrees is not the maximum. During the monsoon season, temperatures drop to an average of 29 degrees Celsius, but an increase in humidity brings little relief as temperatures drop.
Southern thailand
South of Bangkok, especially along the peninsula near Phuket, the climate of Thailand has two distinct seasons. On the west coast, monsoon rains begin in April and last until October; on the east coast, the heaviest rainfall occurs from September to December. Annual rainfall is around 95 inches.
The temperature in Phuket is fairly constant throughout the year, averaging around 28 degrees Celsius. Unlike in the north, however, the southern region of Thailand does not experience the cool monsoon winds during the dry season, resulting in an always hot and humid climate in Thailand.
Peak tourist season
Depending on your itinerary, the best time to visit Thailand is between November and February, when temperatures are lower and the humidity in the atmosphere decreases. Be prepared for lightning freezes at this time, because temperatures can be cold early in the morning and late in the evening.
April in the climate of Thailand is considered the middle of summer, both in the north and in the south of the country. If you are traveling to Thailand primarily to sunbathe on the beach, then always remember the importance of applying sunscreen during this time, avoid the sun from 11am to 2pm, and often let your body cool off in the ocean to prevent discomfort.
