Best time to travel to Thailand – Weather in Thailand

Thailand is one of the most popular tourist destinations on the planet. Friendly people, incredible cuisine and beautiful tropical islands, whilst the weather in Thailand has earned it an enviable reputation. Bangkok itself vies with London every year for the number one place on the list of the worlds most popular tourist destinations. The weather in Thailand sees just two seasons the wet and the dry, temperatures remain high throughout the year. In the south the thin strip of the Thai peninsula proves to be the exception to the rule, with the east and west side having a more monsoon climate, than the tropical climate of the rest of the country. Neither side generally has the same weather as the other, meaning that you will be able to find the sun simply by driving across from east to west or vice versa. It is worth remembering that the wet months will make parts of rural Thailand off limits, as roads become impassable.

The best season for here is between the months of November and February. To the north, the dry season is between November and May, with the rest of the year experiencing heavy rains and cooler temperatures. In the south the west coast has a longer wet season April to October than the east, which runs from September to November. So the east experiences a full 8 months of hot dry weather. The weather in Thailand really is terrific.

The country has three main areas Northern and Central Thailand, The gulf of Thailand and the Andaman Sea area. However, to make these weather maps easier to understand we have grouped them slightly differently, preferring instead to go for North, Central and Southern Thailand. The weather in Thailand is not always easy to describe when sticking to the geographical map of the country.

Northern and Central Thailand

The main land mass of Thailand is the Northern and Central Region. It is home to the famous rice growing areas of the country and the vast majority of the population live in rural areas. To the north, the mountains around the pretty cities of Chiang Mai and Chiang Rai provide a cooler respite from the country’s often searing heat. In the northeast the huge area of Isaan provides a third of Thailand’s population. These people are of ethnic Lao origin and have over the years mixed with the Khmer to form a distinctive ethnic grouping that speak the Isaan language. To the south of the region the countries capital city, Bangkok is home to around 10 million people and receives approximately 18 millions visitors per year. Many cite the main reason for coming as the weather in Thailand.

Destinations include: Bangkok, Chiang Mai, Chiang Rai, Kanchanaburi and Issan

Koh-Phangan

Gulf of Thailand

The seaside resorts of Cha Am and Hua Hin are close enough together to visit both in one day. Hua Hin has for years been the favoured resort for Thailand’s Royal Family. Being just a 90 minute drive away from Bangkok, it is also a popular getaway for both expats and locals living in the capital. Many of the islands in this region are delightful tourist spots and offer everything from the tranquil beaches of Koh Tao to the uproarious, world famous monthly Full Moon Parties of Koh Phan Ngan. Thousands of young revellers flock here every month to party all night long on the main beach. Tourism in this region is the main source of economic growth and occupation. Koh Samui has both the lively Chewang Beach and the more sedate areas around the Big Buddha Beach.

Destinations include: Cha Am, Hua Hin, Koh Chang, Koh Phan Ngan, Koh Samui, Koh Tao, and Pranburi

Krabi

Andaman Sea

This is arguably the most beautiful region of Thailand. It includes Phuket with its rows of girlie bars, great seafood and fabulous beaches. After Bangkok this is the most popular tourist destination in the country. Koh Phi Phi has risen from the devastating effects of the 2004 Indian Ocean earthquake and Tsunami which totally destroyed huge parts of the islands.  Visiting today, it is impossible to believe how it has recovered. Some of the islands in this region have what many regard as the finest beaches in all of Southeast Asia. Typically white sandy strips of beach, fringed with palm trees and glorious crystal clear blue seas. The islands provide some truly great diving experiences and water sport activities, whilst the weather in Thailand makes this one of the world’s great destinations.

Destinations include: Phuket, Krabi, Koh Phi Phi, Khao Lak, Koh Lanta

North of Thailand

The north experiences perfect weather at this time with cool temperatures and no rainfall. This is an ideal time to visit the city of Chiang Mai with average temperatures staying around the 22ºC mark.

South of Thailand

This is the end of the wet season and there will be the odd shower, particularly on the east coast. Both coasts at this time of the year are experiencing a cooling breeze, which keeps the average temperatures down to about 28ºC. It is worth remembering that high tides in January can sometimes mean that there is very little beach left upon which to sunbathe.
