Thailand has a tropical and humid climate in much of the country and throughout the year.

To easily understand the weather and the best time to visit Thailand is by dividing the country into two parts: the north area above Bangkok and the islands, in the south of the country.

In northern Thailand, the seasons are more defined. Between November and February, the weather is drier, not being affected by the monsoons from the north-west area of the country, feeling from time to time a cold breeze.

Between March and May, the weather remains dry, as in previous months, but the temperature tends to warm up. It is the high season in Thailand, the tourism rises to its maximum, and you can celebrate the Songkran festival, curiously, with lots of water.

The other season still north of Thailand, occurs from June to November. The monsoon coming from the southwest dominates the country, and the precipitation reaches its highest level.

In the south of Thailand, there are only two climatic seasons (wet and dry), which, curiously, differs from east and west of the country.

On the west coast, where Krabi or Koh Phi Phi locates, the southwest monsoons reach in mid-April until October, while south-east Thailand, in the islands of Koh Samui and Koh Tao, the precipitation reaches the highest level between September and December.

Although there is all this variation of climate throughout the country, it is possible to go to Thailand at any time of the year.

Visit Thailand in January

New Year’s Eve in Thailand, a country with unique landscapes, worthy of being called paradise, take many tourists from all over the world to put this country as the primary option to pass this date.

January in Thailand has an excellent climate, sunshine throughout the country, perhaps a few showers in the islands, especially on the eastern side.

    23ºC to 33ºC in Bangkok
    25ºC to 33ºC in Krabi and Koh Phi Phi

It is a great reason to visit Thailand in January, especially at New Year’s Eve, escaping the crazy festivals of the islands and Bangkok, and relaxing in something more traditional in the north of the country.

You should expect accommodation prices, tours, events and even food and drinks at their maximum, due to the high tourism demand.

Visit Thailand in February

Temperatures in February continue to rise throughout Thailand, keeping the high season, consequently, the same high prices.

Mornings and evenings are still cold in the north of the country and Bangkok with a hot and humid climate.

March is undoubtedly the month where you will find the best weather in Thailand and, therefore, the best month to travel to this Southeast Asian country.

On this day, tourists and locals gather at an incredible party, throwing water at one another for three full days.

Restaurants and cafes provide plenty of water, often cold, so anyone can carry their water gun and shoot everyone they encounter.

Bangkok, or more specifically, Kao San Road, is the best place to be on this celebration and prepare yourself to be soaked wet all day.

But celebrating Songkran in Chiang Mai has a particular pleasure. Perhaps for the water channels that surround the Old City, or all the ceremonies you can witness while you are there, or just the amount of water you can get and throw to other people. It’s a crazy experience.

The Songkran lasts about three full days, with all the people there wholly soaked all day long. If you are looking to travel to Thailand one day, this is one of the celebrations not to be missed.
