What's the weather like in Thailand in October?

Thailand has a tropical climate with two distinct seasons: the rainy season from May to October, and the dry season for the rest of the year. October signals the shift from the rainy season to the dry one, bringing an end to the heaviest rains.

That said, the weather won't be completely dry and sunny right away. Rain still occurs, but it’s less frequent and lighter than in the previous months. Temperatures stay high at around 28°C, but a slight decrease begins to set in.

It's worth noting that Thailand spans a vast and diverse territory, resulting in variable climatic conditions from one region to another. Northern and northeastern regions may give you cooler temperatures and drier climates compared to the southern coastal areas.

Things to do in Thailand in October?

Chiang Mai and Northern Thailand

Like Bangkok, northern Thailand sees heavy rainfall from June to October, which can impact outdoor activities. But the rain brings lush landscapes and stunning waterfalls, that's why it is a great time to explore Chiang Mai, Chiang Rai, and Pai, especially before the tourist crowds arrive in November.

October in Chiang Mai is a unique experience, with the city transforming into a peaceful and serene place. Start by visiting Wat Phra Singh, the most famous temple in the Old Town, and make your way up to Doi Suthep for panoramic views and a chance to pray for good luck at Wat Phrathat. Bhubing Palace, a royal residence, is also worth a visit. If it rains, consider a relaxing Thai spa or a Muay Thai show indoors.

Next, head north to Chiang Rai to see elephants at the Elephant Valley Sanctuary, which rescues and rehabilitates abused animals. In Pai, explore the Pai Canyon or visit Pam Bok Waterfall, and if you're up for it, check out Tham Lod Cave nearby. But be aware that heavy rains can sometimes make the caves inaccessible.

Bangkok and Central Thailand

Arriving in Thailand, you’ll likely land in Bangkok, the country’s dynamic capital. In October, the weather is warm with occasional rainfall, so it’s a good idea to pack accordingly for both sunshine and showers.

The Grand Palace is a must-see because of its magnificent architecture and extensive history. Don't forget to visit Wat Phra Kaew, which is located inside the compound and is home to the Emerald Buddha, which is extremely significant to Thai culture. Rain or sunny, the temple's exquisite carvings will continue to awe.

October is a great time to explore Kanchanaburi, just a short drive from Bangkok. The weather is pleasant, with temperatures between 24°C and 32°C, making it ideal for a boat ride on the calm River Kwai or a visit to Erawan National Park to admire its stunning waterfalls.

The best islands in Thailand in October

July and October are typically considered low season months, often blending into the rainy season. This means that instead of a beach vacation, surfing on the mainland is a more stable and reliable option. October can be favorable for this reason, but keep in mind that weather patterns on the Thai islands can vary significantly during this month. In some cases, regular services don’t start until the end of the month.

For those seeking adventure, Khao Lak in October offers a bold option. Take the chance to explore Khao Sok National Park, a stunning and untouched area. The waterfalls will be at their best, and you can enjoy exciting hikes, boating on Cheow Lan Lake, and exploring caves. The rainforest will be lush and vibrant, providing a perfect setting for outdoor adventures.

Festivities that you shouldn’t miss out!

• Awk phansa

Awk Phansa is a Buddhist Lent-ending ceremony celebrated in various parts of Thailand, particularly among the Buddhists. The monks’ three-month stay is marked by this ceremony which takes place on the full moon of the 11th lunar month. The festival involves a lot of merit making, giving alms and visiting temples.

• Por Tor (Hungry Ghost Festival)

This month-long celebration is very important for Phuket’s Hokkien Chinese community. The Hungry Ghost Festival is a way of honoring the dead through merit-making ceremonies and Chinese shrines’ various activities. This event is best enjoyed in Phuket, where there are large celebrations, though smaller ones happen in other southern parts too.

• Vegetarian Festival

The Phuket Vegetarian Festival (aka Nine Emperor Gods Festival) will happen from 2nd till 12th of October 2025. Majority of the people celebrating this festival are Thai-Chinese descent during which also marks Taoism’s period of fasting. It usually takes place in Phuket town as well as in Bangkok’s China town where the most prominent celebrations can be found. 

Although this is referred to as a vegetarian festival, food served during these days is more like vegan cuisine since much of it contains meat extracts such as tofu targeting both vegetarians and non-vegetarians alike. Chicken wings or sausages shaped from mock meats taste more than real ones; even the deep fried snacks are all delicious food items that anyone can afford.

This involves wearing appropriate clothing for temples and religious sites, as well as observing rules of conduct in public places.
