Thailand Annual Weather and Holiday Seasons 

Thailand’s tropical climate makes it a perfect year-round destination, with distinct Dry and Wet Seasons that offer unique experiences depending on when you visit.

Dry Season: November to April

The Dry Season is the most popular time to visit Thailand. Running from November to April, this period is characterized by clear skies, warm sunshine, and low humidity. Temperatures during the Dry Season range between 24°C to 34°C (75°F to 93°F), making it ideal for exploring beaches, islands, and cultural landmarks. December through February are the coolest and most comfortable months, offering a pleasant escape from colder climates elsewhere.

Wet Season: May to October

The Wet Season begins in May and continues through October. During this time, Thailand experiences frequent but short-lived rain showers, with temperatures ranging between 26°C to 33°C (79°F to 91°F). While the humidity is higher and the rains more intense, it’s still a beautiful time to visit, especially for travelers seeking fewer crowds and lush, green landscapes. The rain often falls in the afternoon, leaving mornings and evenings free to explore.

Annual Temperature Overview

Throughout the year, Thailand maintains warm tropical weather, with average annual temperatures hovering between 26°C to 32°C (79°F to 90°F). The country's southern islands and coastal regions tend to be warmer, while northern areas can be cooler, particularly in the mountainous regions around Chiang Mai and Chiang Rai during the winter months.

Best Time to Visit

For beach lovers, the best time to visit is during the Dry Season, particularly from November to February, when the weather is perfect for sunbathing, diving, and island hopping. However, the Wet Season is also great for adventure seekers, offering a quieter experience with lush rainforests, waterfalls, and lower hotel rates.

Thailand’s diverse climate means there’s always something to enjoy, no matter when you go!
