Thailand in Winter

Winter in Thailand usually runs from November to February and is widely regarded as the best time to visit the country. During this period, the weather is cool and dry, with temperatures ranging between 20–30°C, making it ideal for beach holidays and city exploration.
A winter itinerary can include popular destinations such as Bangkok, Chiang Mai, Phuket, and Koh Samui. One of the highlights of this season is the Loi Krathong Festival, also known as the Festival of Lights, which usually takes place in November and transforms rivers and lakes into a magical sea of lanterns.
Although hotels and resorts are generally plentiful during this season, it is still recommended to book early, as winter is Thailand's peak tourist period.

Thailand in Summer

Summer in Thailand lasts from March to June, with hot weather and temperatures often exceeding 30°C. Despite the heat, summer offers unique cultural experiences and remains a good time to visit.
The most iconic event during this season is Songkran, the Thai New Year, celebrated with joyful nationwide water fights. Summer is also a great time to explore less crowded islands such as Koh Chang and Koh Kood.
Many resorts and hotels are well equipped with swimming pools, providing a refreshing escape from the tropical heat.

Thailand in the Monsoon Season

Thailand's monsoon season typically spans from July to October, bringing higher humidity and frequent rainfall. However, this season gives the country a different charm, as landscapes turn lush and vibrant green.
The monsoon months are ideal for visiting inland regions such as Chiang Mai, where travelers can enjoy waterfall hikes and nature experiences.
In August, Thailand celebrates the Queen's Birthday, also known as Mother's Day, during which cities are often decorated with beautiful lights, adding a festive atmosphere to the rainy season.
