Where to go in Thailand in January 2027

The short answer

January 2027 suits a route combining the north with one beach base. On average it is one of the driest months across much of the country, with the Andaman coast in its dry season and cool mornings in the north. Historical January averages help you compare regions, but they cannot tell you how the sea or the weather will be on a particular day. Before an outdoor or island trip, check current forecasts and marine warnings, then confirm your departure with the operator.

• Beaches: The Andaman side, including Phuket and Krabi, is in its dry season, which usually makes it the easier choice for island trips.
• Cool mornings: Northern towns like Chiang Mai average around 19 degrees Celsius, and early mornings are colder, so you need a light jacket before noon.
• Islands in the Gulf: Koh Samui and Koh Tao are drying out from their late-year monsoon, but you should still expect some passing showers.
• Watch for: This is peak season, so domestic flights and island ferries book up fast.

January weather at a glance

On average the north and the Andaman coast are in their dry seasons. Over in the Gulf, Koh Samui still averages about 135 mm of rain in January and Koh Tao about 116 mm, and February is much drier. These are monthly averages, not a forecast for your days: check the Thai Meteorological Department’s 7-day forecast, shipping forecast and weather warnings before you travel, and keep a flexible alternative for boat days.

What’s on in January 2027

• National Children’s Day: Expected on 9 January 2027. Military bases and zoos usually open up with family activities, making city traffic noticeably heavier; check local programmes nearer the day.
• Bo Sang Umbrella Festival: Locals decorate the streets with handmade paper crafts about 10 kilometres east of Chiang Mai. It is usually held over the third weekend of January; check the 2027 dates before you plan around it.
• Full Moon Party: The Haad Rin business-maintained calendar lists 22 January 2027, an expected date checked 19 October 2026. Our Full Moon Party guide explains the source and the choice of base. Reconfirm the event before booking ferries.
• Concert in the Park: The Royal Bangkok Symphony Orchestra has played free outdoor shows on Sunday evenings on the grass in Lumphini Park; check its 2027 schedule.

Phuket

Phuket gives you direct international flights and a long stretch of west-coast beaches, in their dry season in January. It is the easiest place to land and immediately start a beach trip without waiting for a ferry.

Best for

A straightforward arrival and plenty of direct transport to smaller islands.

Don’t miss

• West coast sunsets: January is one of the drier months, which gives you good odds of a clear evening for drinks on the sand.
• Island hopping: Speedboat trips to the Phi Phi islands and Phang Nga Bay are a dry-season staple, but any departure can be cancelled for weather, so check with your operator.
• Old Town: Walk past the restored Sino-Portuguese shophouses when the afternoon heat drops.
• Night markets: Eat outdoor street food without the high humidity of the rainy season.

Where to stay

Pick Kata or Karon for long, walkable beaches, or skip it if you hate heavy traffic and prefer a quiet, isolated island.

Krabi

Krabi sits across the bay from Phuket and trades the big-city feel for sheer limestone cliffs dropping into the ocean. January is usually dry, which helps when taking longtail boats out to the Railay peninsula, though any crossing depends on the sea on the day.

Best for

Dramatic coastal scenery and easy access to offshore islands.

Don’t miss

• Railay’s cliffs: Hire a longtail boat from Ao Nang to reach this roadless peninsula.
• Island tours: Join a boat trip to Koh Poda and Chicken Island.
• Tiger Cave Temple: Climb the 1,260 steps early in the morning before the sun gets too hot.
• Night market: Grab fresh seafood in Krabi Town on weekend evenings.

Where to stay

Pick Ao Nang for easy boat access and plenty of restaurants, or skip it if you want the beach right outside your door, as you often have to commute to the sand.

Stays in Krabi→

Koh Lipe

This small island in the far south is known for clear water and walkable beaches that shine in the January sun. January is in its dry season on average, and settled days make for good snorkeling right off the sand. Wind and sea still change from day to day, so check the forecast before a boat trip.

Best for

Clear water, coral reefs and a small-island feel without cars.

Don’t miss

• Sunrise Beach: Wake up early for a quiet stretch of sand.
• Snorkeling trips: Hire a boat to see the reefs around the nearby Tarutao National Marine Park.
• Walking Street: Eat grilled seafood and find a cold beer when the sun goes down.
• Sunset Beach: Grab a spot on the sand for a quiet end to the day.

Where to stay

Pick Sunrise Beach for immediate access to the water, or skip this island entirely if you hate long transit times, as it requires a 90-minute speedboat ride.

Stays in Koh Lipe→

Koh Samui

The Gulf coast has a different climate pattern, and while the heavy late-year storms have usually moved on, Samui is still drying out. It still averages about 135 mm of rain in January, so expect some showers. Any ferry crossing can still be delayed or cancelled when the sea is rough, so check the shipping forecast and your operator’s notices before a ferry day. On average February is much drier.

Best for

A Gulf coast base with an airport and plenty of cafes.

Don’t miss

• Fisherman’s Village: Walk the Friday night market in Bophut for street food and clothes.
• Temple tours: See the Big Buddha on the northern coast when the skies clear.
• Beach clubs: Spend the afternoon on the sand in Chaweng or Lamai.
• Jungle safaris: Take a 4x4 tour up into the hills while the waterfalls are still flowing.

Where to stay

Pick Bophut for a calm beach and good restaurants, or skip Samui if you demand a zero percent chance of rain for your holiday.

Stays in Koh Samui→

Koh Tao

Koh Tao remains a major hub for scuba diving. Underwater visibility often improves as the wet season ends, but it changes with the weather, so ask your dive school about current conditions. It still catches around 116 mm of rain this month, so expect a few passing showers between dive sessions.

Best for

Scuba diving certification and a younger, backpacker-heavy crowd.

Don’t miss

• Diving courses: Get your open water certification at one of the dozens of dive schools.
• Sairee Beach: Watch the sunset and stay for the fire shows and beach bars.
• Koh Nang Yuan: Take a taxi boat to this nearby island for a short hike and snorkeling.
• Viewpoint hikes: Walk up to John-Suwan viewpoint for a look over the southern bays.

Where to stay

Pick Sairee Beach for nightlife and easy access to dive shops, or skip this island if you do not care about diving or snorkeling.

Stays in Koh Tao→

Chiang Mai

January is the smart window for a northern trip, usually giving you clear, sunny days before the smoky season, which this site’s season table flags from February to April. The month averages around 19 degrees Celsius across the day and early mornings are colder, making it a very comfortable time to explore the old city moat.

Best for

Cool mornings, hundreds of temples and a huge cafe scene.

Don’t miss

• Doi Suthep: Ride a red truck up the mountain to see the golden temple overlooking the city.
• Sunday Walking Street: Walk the length of the old city for crafts and street food.
• Coffee culture: Spend a morning in the Nimman area, which has a dense concentration of cafes.
• Elephant sanctuaries: Visit an ethical rescue center in the surrounding mountains.

Where to stay

Pick the Old City to be within walking distance of the major temples, or skip Chiang Mai if you only want beach time. To weigh the Old City against Nimman, see Old City or Nimman.

Stays in Chiang Mai→

Pai

Pai involves a winding mountain transfer, so decide whether the journey fits your trip before adding it to a northern route. January usually brings cool weather to the valley; pack a layer for early starts, as Pai averages around 18 degrees Celsius in January and the early mornings are colder still.

Best for

Mountain views, scooter trips and a relaxed, bohemian atmosphere.

Don’t miss

• Pai Canyon: Walk the narrow dirt ridges at sunset for a view over the valley.
• Hot springs: Soak in the warm water early in the morning when the air is still cold.
• Walking Street: Eat your way through the nightly street food market in the center of town.
• Waterfalls: Hike to Pam Bok or Mo Paeng while they still have water from the rainy season.

Where to stay

Pick a riverside bungalow for quiet mornings, or skip Pai if you get severe motion sickness on the 762 curves from Chiang Mai.

Stays in Pai→

Bangkok

Bangkok fits a January route for food, markets and onward transport. The city averages just 16 mm of rain in January, one of its driest months, so outdoor plans usually work out; check the forecast for your day anyway.

Best for

Street food, historical sites and easy transit connections to the rest of the country.

Don’t miss

• The Grand Palace: Arrive right when it opens to beat the crowds and the midday sun.
• Chinatown: Eat dinner on Yaowarat Road as the neon signs light up.
• Chao Phraya River: Take the public ferry to see the temples from the water.
• Chatuchak Market: Shop for clothes and souvenirs over the weekend.

Where to stay

Pick Sukhumvit to be right on the Skytrain line, or skip Bangkok entirely if you hate big crowds and concrete heat.

Stays in Bangkok→

What to watch for

• Peak season crowds: January is busy, so rooms in popular spots fill early. Book ahead.
• Air quality changes: The air in the north is usually clearer in January than later in the dry season, when smoke often builds from around February. Check current air-quality readings close to your trip. Our Chiang Mai burning season guide shows where to check them and how to read them.
• Chinese New Year: This major holiday falls on February 6, 2027, so you avoid the travel spike if you stick to January.

How long to stay

With 10 to 14 days, combine one beach base with time in Bangkok or Chiang Mai. Allow for travel between them rather than trying to include every region. With less time, choose one region and leave room to change a weather-dependent boat day. To choose between the two beach bases, see Phuket or Krabi.
