Weather in Thailand in October| First-Timer Tips (2025 Update)

October marks the end of the monsoon season in most parts of Thailand. If you're visiting Thailand in October, you're in that sweet, in-between season, where monsoon rains begin to ease, prices stay low, and crowds are blissfully thin.

It's not quite beach-perfect yet, but if you're open to some flexibility (and rain), October can be surprisingly rewarding, especially for couples looking for quiet escapes or cozy hideaways.

What's the Weather Like in Thailand in October?

October is a turning point in Thailand's weather. The monsoon season starts to retreat, but not all regions recover at the same pace. The north dries out first, followed by the center, while the south—especially the Andaman Coast—is still deep in rainy season.

For the daily weather, you'll still get those classic tropical downpours—short, intense bursts of rain, often in the late afternoon or early evening. But they're broken up by plenty of sunny spells, averaging 6–8 hours of sunshine a day.

Due to the tropical weather, the temperature in October remains around 31°C (88°F) in the daytime. With humidity at 75–85%, it can feel more like 35°C (95°F).

Here's a breakdown to help you pick the right region for your trip:

Chiang Mai and Northern Thailand—Best Weather & Value in October

• Chiang Mai, Chiang Rai, Pai, Mae Hong Son, Sukhothai

With about 9 rainy days, October in northern Thailand is that magical blend of low-season pricing and high-season weather. The further north you go, the drier the weather can get.

With higher altitude, you could get slightly cooler temperatures than the rest of the country. The mountains, like Doi Inthanon, could even drop to 20°C (68°F).

Best Places to Go:

Chiang Rai is a smart pick if you want to avoid crowds and stay dry. This gateway city to the Golden Triangle sees the least rain in the region. It's also home to some of the most exclusive elephant hotels in Thailand—ideal for a once-in-a-lifetime escape without the high-season price tag.

Chiang Mai offers richer experiences even on a rainy day. Meeting elephants, almsgiving, and cooking classes are rarely affected by rain. If you're into light trekking, the hills near Doi Inthanon offer gentle routes and cooler air. Just check ahead—some summit trails may still be off-limits in October.

Bangkok and Central Thailand — Still Wet but Manageable

• Bangkok, Kanchanaburi, Ayutthaya, Khao Yai, Pattaya,

Rain is still in the picture across central Thailand in October. Inland cities like Bangkok, Khao Yai, Kanchanaburi, and Ayutthaya see relatively little rainfall, averaging around 13 days of rain. Coastal areas such as Pattaya, Hua Hin, and Trat get more rain, though it's still only about half as much as in September.

Best Places to Go:

Bangkok is a year-round city. Rain barely slows it down. You can explore palaces and temples in the morning, then duck into museums, boxing stadiums, or luxury malls when the rain comes. It's also a great place for food lovers, with cooking classes and street eats that run rain or shine.

If you're looking to escape the heat or city buzz, Kanchanaburi is just a couple of hours away. Think floating raft houses, Erawan Waterfall, train rides along the Death Railway, waterfalls, and World War II history. Khao Yai National Park is another cool escape for hiking and wildlife.

History buffs should consider Ayutthaya for a day trip. Just an hour from Bangkok, the ancient ruins never lose their charm, whether it's a sunny or rainy day.

Can You Visit Thai Islands in October, Like Phuket or Koh Samui?

Short answer: Not ideal, but not impossible.

The southern islands are still deep in monsoon mode. On the Andaman Coast (Phuket, Krabi, Khao Lak), you'll see the heaviest rainfall of the year—up to 300 mm, with storms hitting 20+ days of the month.

That said, Koh Samui and nearby Koh Tao, sitting in the Gulf of Thailand, get slightly better weather in October. You may get a few dry mornings and occasional sun, but also expect gray skies and unpredictable showers, especially in the afternoons. Travel forums say you might get 2–3 sunny days out of 10.

Where Not to Go in October

Phuket, Krabi & the Andaman Coast get hit with frequent downpours, strong waves, and canceled boat tours in October. Around Koh Phi Phi & other small islands, diving/snorkeling sites have limited visibility and safety concerns. The popular Similan Islands are still closed until late this month.

Is October an Expensive Time to Visit Thailand?

Not at all. October is part of the shoulder season, so you'll find fewer tourists and better deals. So you get more space, whether that's on a jungle trail, in a boutique café, or at a mountaintop temple at sunrise. Flights and hotels are often 20–40% cheaper than in peak months (November to February).

On my last trip to Chiang Mai in September, which shares similar off-season perks with October, I stayed at the Bush Camp Chiang Mai, an elephant camp, and saved $110 per person compared to their December rates.

What's Happening in Thailand in October? (Events & Festivals)

October is quiet in terms of major festivals—another win if you dislike crowds—but there's one event that stands out: the Vegetarian Festival, especially in Chinatown.

Phuket goes all in, with fire-walking, body piercing, and a buzzing, almost eerie energy. Bangkok's Chinatown is a good bet too. For food lovers, it's pure gold—vegan pad Thai, grilled mushrooms, and all kinds of plant-based spins on Thai street food.

What to Pack for October in Thailand

• Light rain jacket or poncho
• Quick-dry clothing & foldable umbrella
• Non-slip sandals or walking shoes
• Sunscreen (yes, even when it's cloudy)
• Light sweater or jacket for cooler evenings up north
• Mosquito repellent, especially in mountain and jungle areas
