Best time to visit Phuket

Calm seas or the big party month?

Go from December to March, the dry season, when the skies are clear and the sea is calm enough for every boat day.

The Andaman Sea around Phuket is calmest from November to April.

For a party trip, December is the big month, with EDC Thailand in Phuket from 18 to 20 December 2026 and New Year's Eve.

For the best value, go in November, a good compromise with fewer crowds and lower prices, or in the rainy season. Ask Tanner which month suits the group.

Month by month

The year runs from the calm, dry peak of February to the wet, rough-sea peak of September, month by month below.

The temperatures are daytime highs, and the sea column tells you which boat days run.

Pick the month for the boat days first, then the events. Ask Tanner to match the boat to the month.

The sweet spot: January and February

January and February are the best months for Phuket: dry, calm and about 33°C to 34°C, with only three or four rain days a month.

Tanner's pick for a group: February, the driest month of all.

December is the busiest and the most expensive, with the festive season and EDC.

Ask Tanner to book villas and yachts early for December and January.

High season, November to April

For a full week of boats and beaches, come in high season, November to April, when the boats run every day.

The Similan Islands national park opens from 15 October 2026 to 15 May 2027, the Government Public Relations Department says (checked November 2026), so the dive trips fit the high season exactly.

Songkran, Thailand's New Year water festival, runs from 13 to 15 April, the wildest days on the island.

Insider tip: March and April are the hottest months, so plan the boat days early in the morning.

Ask Tanner to book the Similans while they're open.

October, the underrated month

October starts wet and clears by the end, as the rainy season ends and the sea starts to calm.

The Phuket Vegetarian Festival fills the Old Town in October: nine days of processions, shrine rituals and street food.

The Similans open on 15 October, and prices are still at low-season levels.

For a group that wants value and an event, October is the underrated month. Ask Tanner for next year's festival dates.

The rainy season, May to October

The Phuket rainy season runs from May to October, when the southwest monsoon brings rain and a rougher sea on the west coast.

June to October see 19 to 23 rain days a month, so we keep a spare day for the beach and the boat.

September is the wettest month, with about 361 mm of rain.

The clubs, Bangla Road and the villas carry on all year. See our Thailand rainy season guide. Ask Tanner for a villa that makes a wet afternoon a party.

Boat days by season

For boat days, come November to April, when the sea is calm and reliable. From May to October it's rough, and trips can cancel.

Maya Bay on Phi Phi closes from 1 August to 30 September for the national park's yearly break, as it did in 2026 (checked October 2026).

In the wet months, any boat trip can move or cancel with the weather.

Build a spare day into the plan for the boat. See Phuket yachts, and ask Tanner to hold a back-up boat day.

When it's cheapest

It's cheapest in the low season, from May to October, when hotels and villas cost less and the crowds thin out.

November is the shoulder month, a good compromise for fewer crowds and lower prices, and the rainy season, especially August and September, is the cheapest.

For a group, villas start from ฿18,500 a day all year, and a full party week for 12 starts from about ฿300,000.

See what a Thailand trip costs. Ask Tanner to price your dates.

Which beaches, when

The west coast has them: Kata and Nai Harn for an easy swim, Kamala and Bang Tao for the beach clubs.

Phuket's west-coast beaches are at their best from November to April.

In the rainy season, swim only where there's no red flag on the beach.

See our best beaches in Thailand and things to do in Phuket.

In high season, Kamala at sunset is the pick. Ask Tanner for a beach club table.

The rest of Thailand

Thailand's seasons don't line up, and for Phuket and the Andaman coast the roughest months are August and September.

The Gulf islands of Koh Samui and Koh Phangan get most of their rain from October to December, the Thai Meteorological Department says, so they're the better choice when Phuket is wet in summer.

Chiang Mai's burning season runs from about mid-February to April and peaks in March.

See our best time to visit Thailand and Koh Samui vs Phuket.

Ask Tanner where the weather's best for your dates.

Pick your month

Pick your month: December to March for the calm sea, November or October for value, and December for EDC.

Then add the villa, the boat and the club evenings.

Ask Tanner, and he builds the week around your dates.
