Thailand in July

Why July works

Thailand in July works on the Gulf side. It's the rainy season, but storms rarely last all day, and Koh Samui, Koh Phangan and Koh Tao have some of their sunniest weeks of the year.

The Andaman coast gets more rain and rougher seas, so there we plan pool days, not boat days. The two Buddhist holy days in the third week are the only days to plan around.

Insider tip: Hua Hin is one of the driest beach towns in July and about three hours from Bangkok by car, if the group wants a weekend close to the city.

Build July around Koh Samui. Ask Tanner which island suits your group.

How much it rains

Thailand in July weather is wet but rarely washed out: short, heavy storms can flood the streets for about an hour, then the sun comes back. Koh Samui averages about 117 mm over 11 rain days and Phuket about 240 mm over 16, on the Thai Meteorological Department's 1991–2020 normals.

Red flags are common at Patong, Kata and Karon, and Koh Chang has its wettest month of the year. Base the group on Samui, and you get the sun. Ask Tanner for a Samui villa.

What's on in July 2027

July 2027 has two Buddhist holy days with alcohol bans, Asalha Bucha and Khao Phansa, and the King's Birthday on Wednesday 28 July.

Asalha Bucha falls on Sunday 18 July and Khao Phansa on Monday 19 July 2027, the Bank of Thailand's 2027 holiday list shows, with banks closed on the Monday. The Full Moon Party moves off the holy days, and its own dates page lists Tuesday 20 July.

Khao Phansa is also when Ubon Ratchathani parades its giant carved candles, if the group wants a day in Isaan.

See Thailand public holidays and the Thailand party calendar, and ask Tanner to confirm the dates before you fly.

Two quiet days, planned

Plan the two holy days as villa days, with your own bar stocked the night before. On both days shops, convenience stores and ordinary bars and restaurants stop selling alcohol.

Licensed entertainment venues, hotels, international airport terminals and listed tourist-area venues and events are exempt and can still serve, under the Office of the Prime Minister's notice in force since 10 May 2025.

The villa gets a DJ by the pool from ฿8,000 a day and an open bar at ฿1,500 each, set up before the ban. Party hard the night before, then take the two quiet days by the pool before the Full Moon.

Plan it with Tanner, and the two quiet days are covered.

What to book first

Koh Samui sells out first in July, because European summer holidays fill the Gulf. Book Koh Samui, Koh Phangan and Koh Tao a few weeks ahead.

Samui flights and villas for the second half of July go first. Villas near Haad Rin for the Full Moon go next. Bangkok clubs, Pattaya villas and anything on the Andaman side are easy, and prices sit well below the winter peak.

Ask Tanner to hold the Samui flights early.

Where to take the group

Base your group on Koh Samui for the beaches, take the boat to Haad Rin on Koh Phangan for the Full Moon, and go to Bangkok for the clubs. If you go to Phuket in July, stick to the beach and the pool and skip the boat trips.

Bangkok has the rooftops and the big clubs. Licensed entertainment venues in Bangkok and licensed venues inside hotels may open until 4am; ordinary bars and restaurants close earlier, usually by 2am. The licensed clubs are in Silom, RCA and Ratchada.

Pattaya is about two hours from Bangkok, with pool villas from ฿12,500 a day. In Phuket, take a villa with a pool, from ฿18,500 a day.

See Koh Samui to Koh Phangan, and ask Tanner for the boat across.

Things to do in July

Beach days on Koh Samui, a catamaran on a calm Gulf morning, and the Full Moon across the water after the holy days.

For 12 of you in July, base on Samui: a villa, a catamaran day, and the boat to Haad Rin on Koh Phangan for the Full Moon. A Koh Samui catamaran for up to 12 is quoted to your plan, with the DJ, the bar and the party layer on top.

In the city, Bangkok's licensed clubs and hotel rooftops still serve on the two holy days; ordinary bars and restaurants stop selling.

Ask Tanner for a Samui week in July.

Travel tips for July

Pack a light rain jacket, quick-dry clothes, sandals for flooded streets, strong sun cream for the Gulf and a dry bag for the boats.

On the holy days, ordinary bars and shops stop selling alcohol, so keep the drinking at the villa or a licensed club.

Smart casual for the clubs: a collared shirt, dark jeans and closed shoes.

Ask Tanner for the club dress code before you fly.

Is Thailand better in July or August?

July and August are much alike: wet on the Andaman side, with the Gulf islands the best bet. July has the two ban days; August has Mother's Day on 12 August and no ban days.

Pick July for the Full Moon after the holy days. Pick August to skip the ban days, with the same Gulf weather. Tanner's pick for either month: Koh Samui over Phuket.

See Thailand in June for the month before, and ask Tanner which month fits your dates.
