Asia > Thailand: Weather, Map, Costs and Travel Guide

The country has an equatorial climate in the extreme south, while the central and northern areas have, in turn, a tropical monsoon climate.

The north is hilly and even mountainous in places, but most of the country is situated at low altitude.

The majority of Thailand suffers from heavy downpours, mainly from May to October.
During the monsoon, the winds of the Indian Ocean bring warm moist air and a lot of cloudy weather.

From November to April there is the dry season. This is the period of the northeast monsoon and the wind blows from China.

At the centre and south of the country, there is little climate variation, but it is generally colder in the northeast.

The hottest months are April and May.
Sunlight is less between June and September as it only shines between 4 to 5 hours a day.
The rest of the year, it shines 9 to 10 hours daily.

The wet season is quite oppressive in the majority of the country because of the combination between hot and moist weather.

A tropical climate clearly dominates the country: The rainy season lasts from June to October, but this does not prevent beautiful sunny periods, but with occasional storms and increased rainfall in the north. The dry season is between November and May with high temperatures from March. The south is colder between April and June. So you can best enjoy a visit between November and March before the hot weather, avoiding the major tourist areas which are quite numerous.
