Phuket in August 2026: Weather, Prices, Things to Do
In brief: August in Phuket is the peak of low season and the cheapest hotel prices of the year. Air temperature is 31°C during the day, 25°C at night, sea water 28°C. It rains on 16 days of the month, but usually in the afternoon for 1–3 hours. Western beaches are for surfing, eastern ones for swimming. Tourist numbers are minimal, and five-star hotels are available at the price of a three-star in high season.
Phuket Weather in August
August is one of the wettest months, but "wet" in Phuket doesn't mean "rainy all day." The morning is almost always sunny, clouds roll in around 2:00 PM, then a short powerful downpour — and clear skies again. Some days have no rain at all. Others (less commonly) pour from morning to evening. But there are only 2–3 such days per month at most.
| Parameter | Value |
|---|---|
| Daytime air temperature | 31°C |
| Nighttime air temperature | 25°C |
| Sea water temperature | 28°C |
| Rainy days | 16 |
| Rainfall | ~310 mm |
| Humidity | 82–87% |
| Sunshine hours per day | 5–7 |
| Wind speed | 12–20 km/h (SW) |
| UV index | 9–11 (very high) |
| Season | Low (LOW) |
The temperature is stable — daytime never gets hotter than 33°C or cooler than 29°C. At night you'll still need air conditioning — 25°C at high humidity feels like 28°C.
From personal experience: August is slightly milder than September in terms of rainfall. Rain in August usually starts later — closer to 3:00–4:00 PM — and ends faster. You can get excellent stretches of 4–5 sunny days in a row when you forget it's officially rainy season. But then you might get hit with two days of heavy rain — that's normal.
What to Wear in August
Wardrobe for August in Phuket is about practicality, not style. At 85% humidity, regular clothes simply don't have time to dry. Here's what you'll actually need:
- Compact rain poncho (better than an umbrella, especially on a scooter — wind will blow an umbrella inside out)
- Quick-dry shoes — sandals, Crocs, or water shoes. Forget sneakers and trainers: they'll get soaked and won't dry
- Waterproof bag / dry bag for the beach and the city
- SPF 50 sunscreen — UV index is 9–11 even on cloudy days; you can burn in 30 minutes
- Insect repellent — mosquitoes noticeably increase after rains, especially at sunset
- Light long-sleeve top — air-conditioned malls and restaurants can be chilly (20–22°C)
- Power bank and waterproof phone case — getting your phone drenched in a tropical downpour takes about one minute
- Light clothing made from natural fabrics — cotton, linen. Synthetic fabrics are unbearable in this humidity
What's Open and What's Closed
Open: Phi Phi Islands (weather permitting), Phang Nga Bay, James Bond Island, all land-based activities (rafting, zipline, ATV), temples, night markets, shows, waterparks, diving at eastern sites.
Closed: Similan Islands (until November), some dive sites off the west coast, some beach clubs on Surin and Bang Tao operate on limited schedules.

Best Tours and Activities in August
August is the time to shift your focus from sea excursions to land-based and cultural ones. Here's what I recommend:
- Phang Nga Bay by kayak — sheltered waters, no waves, runs 365 days a year. One of the most beautiful excursions in Phuket in any season
- Rafting in Khao Lak — in August the rivers are at maximum flow, making it the best rafting of the year. Class III–IV rapids, adrenaline guaranteed
- Phi Phi — running, but cancellations happen. Book the day before and be ready to reschedule
- Elephant Jungle Sanctuary — elephants only enjoy the rain. Half-day excursion, from 2,500 THB
- Cooking class + market visit — half a day, perfect in bad weather. Learn to cook authentic tom yum and pad thai, from 1,500 THB per person
- Tiger temple (Wat Suwan Khiri) — 1,237 steps, much easier to climb in cloudy weather than in the high-season heat
- Hanuman World zipline — the jungle in rainy season is especially beautiful: dense greenery, mist, waterfalls at full force
- Old Town Phuket — a walking tour through the old town with Sino-Portuguese architecture, street art, cafes. Much more comfortable to stroll in overcast weather

Personal Experience: How I Spend August in Phuket
After more than four years on the island, I've stopped fearing August rains. On the contrary — I've grown to love this time. The island is empty, every restaurant has a table, roads have no traffic, and the nature is incredibly green. Waterfalls run at full force — if you haven't visited Bang Pae or Ton Sai waterfall, August is perfect for it.
My typical August day: breakfast at a Thai cafe (khao tom or rice porridge — from 40 baht), at 9:00 AM I'm at Ao Yon beach, swimming until noon. Lunch at a seafood restaurant in Rawai (fresh seafood at 200–400 baht per dish — in high season, the same portions cost double). After lunch — work or spa. If it rains — I head to Central Festival or a coworking space. By evening I'm off to the Phuket Town night market, where life buzzes under awnings regardless of the weather.
What I don't like about August: murky water for snorkeling, closed Similan Islands, and occasional cancellations of sea excursions. If the underwater world is your priority, come from November through April.
Events and Festivals
- Mother's Day (August 12) — a national holiday honoring Queen Sirikit. Buildings are decorated with blue lights, it's a public holiday. Many restaurants and hotels run special promotions
- Phuket Bike Week (sometimes falls in August) — a major biker festival with participants from across Southeast Asia
- Mall sales — Central and Jungceylon run summer sales with 30–70% discounts
- Mangosteen and rambutan season — tropical fruits at the markets for minimum prices, from 30 baht per kg
Tips from a Local Resident
- Book a hotel for the whole month — for rentals of 2 weeks or more, discounts are 40–60%
- Morning is everything — plan beach time and activities before 1:00 PM
- Download Grab and Bolt — finding a taxi in the rain is tough; the app saves the day
- Try street food — night markets operate in any weather under awnings
- Get insurance that covers tour cancellations — it'll come in handy on stormy days
- Don't fear the rain — 20 minutes after a downpour the asphalt is already dry at 31°C. Find travel companions for excursions — in low season you can save nicely on group trips
- Choose a hotel with a covered pool — or at least a pool with a canopy. On rainy days this is a lifesaver, especially with kids
- Visit the waterfalls — in August they're full and beautiful. Ton Sai and Bang Pae are free to visit
