A month-by-month guide of when to visit Thailand
Thailand is one of those rare places that works brilliantly year-round—it just depends on what kind of trip you’re after.
The most popular time to visit is between November and February, when the weather is cooler (by Thai standards) and mostly dry. It’s a brilliant time for island-hopping, temple-hopping, or both. That said, it’s also when places book up fastest, so if you’ve got your heart set on a particular hotel or island, planning is key.
March to May is the hottest part of the year, and while that puts some travellers off, it’s also when you’ll find fewer crowds and better prices. If you don’t mind the heat, it can be a fantastic time to explore cultural sights or even join in with Songkran—the Thai New Year—which takes place in April and involves nationwide water fights and plenty of good-natured chaos.
The rainy season (June to October) has a reputation for being a washout, but it really depends on where you go. You’ll get lush, green landscapes and quieter beaches, and over on the Gulf side—think Koh Samui or Koh Phangan—you’ll often find sunnier days than expected. Prices drop too, so it can be a great time for a more budget-friendly trip if you’re happy to dodge the occasional downpour.
Whatever time of year you visit, Thailand’s mix of culture, food, nature and beaches always delivers.

January
January is one of the most delightful months to visit Thailand. The weather is characterized by pleasant temperatures and dry conditions. Daytime temperatures typically range from 25°C to 32°C, making it perfect for outdoor exploration.
The month kicks off with vibrant New Year's Eve celebrations in major cities, such as Bangkok and Chiang Mai. Spectacular fireworks displays light up the night sky, and many establishments host special parties and events. Towards the end of January, the Chiang Mai Flower Festival takes place, featuring colourful parades, floral exhibitions, and garden competitions, adding a touch of natural beauty to your visit.
February
February is a continuation of the pleasant weather experienced in January. The cool, dry conditions persist, creating a comfortable atmosphere for travellers.
Chinese New Year, celebrated in various Thai-Chinese communities, adds a dash of cultural festivities to the month. In Chiang Mai, the Lantern Festival coincides with this period, where you can release lanterns into the night sky for good luck.
March
March is still a great time to visit Thailand. While temperatures start to rise as the month progresses, it remains relatively comfortable with low humidity and minimal rainfall.
The highlight of March in Thailand is the Songkran Festival, marking the Thai New Year. This event is celebrated with water fights, parades, and traditional ceremonies. It's a unique cultural experience that's both fun and refreshing.
April
April marks the beginning of the hot season in Thailand. Temperatures can soar, reaching up to 40°C (104°F). It's generally dry but increasingly scorching.
The Songkran Festival celebrations often continue into the first half of April, making it a vibrant and festive time to visit. Be prepared to get drenched in friendly water fights as part of the festivities.
May
May is still part of the hot and dry season. However, temperatures might be slightly more bearable compared to April.
While May doesn't feature any major festivals, it's an excellent time to explore Thailand's beautiful beaches and islands without the peak-season crowds. The clear skies and warm waters make it ideal for beach vacations and water activities.
June
June is the start of the rainy season in most parts of Thailand. Humidity increases, and sporadic rainfall becomes more common.
While there are no major festivals in June, this quieter period allows you to explore popular tourist destinations with fewer crowds. Consider indoor and cultural activities during occasional downpours.
July
July is firmly within the rainy season in most of Thailand. Frequent downpours are expected, especially on the west coast and in northern regions.
July doesn't feature significant events, but it's a time to experience Thailand's lush green landscapes. You can visit national parks and enjoy the vibrant flora that thrives during the rainy season.
August
Rainfall continues in August, but the east coast islands like Koh Samui and Koh Phangan tend to have better weather during this period.
On August 12th, Thailand celebrates the Queen's Birthday, a national holiday. It's a time when Thais show their love and respect for the monarchy.
September
September marks the transition as the rainy season starts to wane. The weather gradually improves, particularly towards the latter part of the month.
Mahidol Day on September 24th is another national holiday, commemorating the life and contributions of Prince Mahidol, the father of modern medicine and public health in Thailand.
October
October is a great time to visit as the rainy season recedes, and the weather becomes more comfortable. You'll notice a decrease in rainfall, and conditions become ideal for travel.
November
November offers pleasant weather with less humidity. It's an excellent time for outdoor exploration and activities.
Loy Krathong, the Festival of Lights, is a major event in November. During this celebration, people release lanterns and float decorative krathongs (small rafts) on rivers and lakes, creating a magical, illuminated spectacle.
December
December is the peak tourist season in Thailand. The weather is cool and dry, providing ideal conditions for various outdoor activities.
Christmas and New Year's Eve are widely celebrated in major cities and tourist areas. You'll find festive decorations, special dinners, and lively parties to ring in the new year.
