Phuket in May 2026: The Start of the Low Season
In short: May on Phuket marks the official start of the low season (green season). Daytime temperature is 32°C, nighttime 25°C, and the sea is 29°C. There are already 18 rainy days per month — full-blown tropical downpours, usually in the afternoon. The Similan Islands close on May 15. On the upside, prices drop by 50–60%, surfing waves arrive, and tourist crowds virtually disappear. May is for budget travellers, surfers, and those who appreciate peace and quiet.
My Personal Experience: How I Spend May in Phuket
I have been living in Phuket for several years, and May is one of my favourite months. The tourist chaos ends and the island seems to exhale. In the morning I head to Kata or Nai Harn — the beach is empty, not a single sun lounger, just stray dogs and a couple of surfers. By 1 pm the sky starts to darken, and I already know: a downpour is coming within the hour. I ride home, work while the rain drums on the roof, and by 4 pm the sun is out again.
The most valuable thing about May is the feeling of the real Phuket. Markets cater to locals, not tourists. Food prices return to normal: tom yum for 60 baht, pad thai for 50. Restaurants that charged 500 baht per dish in January offer lunch for 150 in May. I deliberately visit places I avoid in winter — in May they become reasonable.
One more detail: nature is at its most beautiful in May. After the first rains, everything turns green within days. Hills that were scorched and brown in March–April are covered in lush tropical greenery. Waterfalls gain strength — Bang Pae and Ton Sai become full and powerful. If you love photographing nature, May is the best month.
Songkran Aftermath: What to Expect in Early May
Songkran (Thai New Year) falls on April 13–15, and its aftereffects linger into the first week of May. Many Thai businesses are only just getting back to their normal routine. Some cafes and shops in early May are still closed or running reduced hours — owners visited their families in other provinces.
On the other hand, by May the "high-season" surcharge on everything has completely ended. In April some tour operators still held winter prices, but in May the low season officially begins. This applies to accommodation too: a monthly condo rental with a pool that cost 30,000–40,000 baht in January drops to 12,000–18,000 baht in May. I know people who deliberately come for long stays starting in May to get a great apartment for next to nothing.
Roads after Songkran are also more pleasant: traffic jams in Patong disappear, beach parking lots are empty. On Route 402 (the island's main road) you can drive in peace in May, without the endless congestion near Central and Tesco Lotus.
Air and Water Temperature in May
The temperature in May is 32°C during the day and 25°C at night. Slightly cooler than April because the rain brings the heat down. After a downpour the temperature can drop to 28°C for an hour or two — a welcome relief.

The sea is 29°C — still very warm. Swimming is comfortable, but not everywhere safe due to waves and currents on the west coast.
Humidity in May is 80–85%. Along with the rain comes mugginess. Mornings can be clear and even fresh, but by noon the humidity builds up. Air conditioning is not a luxury but a necessity. Compare May with other months in our overview: Phuket weather by month.
Rainfall: How Much Rain in May
18 rainy days is a serious number. Total rainfall is around 250–300 mm. This is already a full-fledged rainy season, although the peak (September) is still far off.
Rain patterns in May: mornings are often sunny (until 12:00–1:00 pm), the sky clouds over after lunch, and a downpour hits for 1–2 hours. It may clear up by evening. There are also entirely overcast days, but they are rare — 2–3 per month.
Wind picks up — the southwest monsoon gains strength. Waves of 1–2 metres appear on west coast beaches. Red flags go up at Patong, Karon, and Kata. Rip currents are dangerous — do not ignore the lifeguards' warnings.

Best Beaches in Phuket in May
In May you need to choose your beaches wisely — not all of them are safe:
Nai Harn — a bay sheltered from the open waves. On calm days you can swim here. A beautiful beach with very few people. But check the flags — even here it can be dangerous during storms.
Rawai / Chalong (east coast) — no waves at all. Shallow and calm. Not the most photogenic beaches, but safe for swimming with children. Seafood markets are nearby.
Ao Yon — a hidden bay on the east side. Kayaking, SUP, calm water. In May it is quieter than usual — almost a private beach.
Bang Tao (northern section, near Laguna) — surfing starts here in May. Medium waves, 1–1.5 m. Surf schools operate with instructors. Not the best choice for swimming.
Kata (for surfing) — Phuket's classic surf spot. In May the waves begin — long, even, perfect for beginners. Board rental is 200 baht/hour. A lesson with an instructor starts from 1,500 baht.
Best Excursions in May
Similan Islands (until May 15) — last chance of the season. If you arrive in the first week of May, give it a try. But be ready for cancellations due to waves. Book with flexible rescheduling. From 2,200 baht.
Phang Nga Bay (James Bond Island) — open year-round. The bay is sheltered from the monsoon — the water is calm. Canoeing through caves, limestone cliffs. In May there are almost no tourists. From 1,200 baht.
Surfing lessons — the main sporting attraction of May. Schools at Kata (Kata Surfing, Phuket Surf) take complete beginners. A 2-hour lesson from 1,500 baht. By the end of the day you will be standing on the board.
Rafting + zip-line + ATV — active land-based activities that work in the rain. River rafting in May is fuller and more exciting. Zip-lining through the jungle after rain — the greenery is incredible. Combo package from 2,500 baht.
Cooking classes and spa — a rainy day is the perfect time to cook tom yum or enjoy a 2-hour Thai massage. Cooking class from 1,500 baht, spa from 1,000 baht.
Hotel Prices in May
May is the beginning of the lowest prices of the year. Hotels empty out rapidly and prices plummet.

Events and Holidays in May
Visakha Bucha (full moon in May) — the most important Buddhist holiday: the day of Buddha's birth, enlightenment, and passing. Temples hold candlelit evening ceremonies. At Wat Chalong — hundreds of monks and worshippers. Alcohol is not sold.
Royal Ploughing Ceremony (early May) — a royal ceremony marking the start of the rice planting season. In Bangkok it is a grand affair; in Phuket it is simply a public holiday.
Start of the surfing season — an informal "holiday" for the surf community. Schools open for the season, first competitions at Kata. The atmosphere is relaxed and friendly.
Green Season promotions — hotels, restaurants, and spas launch special offers to attract guests. Half-price spa packages, complimentary dinners with bookings, room upgrades.
What to Pack and What to Wear in Phuket in May
May is a month where you need to plan your wardrobe in advance. The main rule: everything should dry quickly. A cotton T-shirt after a downpour stays damp until evening, while a synthetic one dries in 30 minutes. I switched to nylon and polyester clothing and have not looked back.
- Rain jacket or poncho: lightweight, packable. An umbrella works too, but on a motorbike an umbrella is useless — you need a rain jacket. Best to bring one from home — the disposable ones from 7-Eleven (50 baht) tear within a week
- Waterproof backpack or dry bag: for electronics and documents. A downpour can catch you anywhere. A 10-litre dry bag costs 200–300 baht at the market
- Shoes with non-slip soles: wet pavements plus Phuket's hills equals slippery. Trekking sandals are ideal. Regular flip-flops on wet tiles are dangerous — I have seen people fall
- Rash guard: for surfing (protection from sun and reefs) and for swimming at beaches with jellyfish
- Insect repellent: strong formula. After the rains, mosquitoes breed actively. DEET 30%+ or natural citronella
- Quick-dry clothing: synthetic fabrics are better than cotton here — they dry in an hour. Bring 2–3 changes
- Motion sickness tablets: if you are planning boat excursions — the sea is rougher in May
- Thin sweater or windbreaker: air-conditioned spaces (shopping centres, buses, minivans) can feel cold after the outdoor heat. The temperature contrast is noticeable
For footwear, trekking sandals like Teva or Keen work best — they grip on wet surfaces, dry quickly, and suit both the beach and the town. Leave your trainers at home — they will get soaked on the first day and take two days to dry.
Practical Tips from a Local
Try surfing. May is when the waves begin. Finding travel companions for a surf session is easy. If you have never stood on a board, Phuket in May is perfect for your first time. The waves are soft and long, the instructors experienced. Kata is the best spot for beginners.
Plan around the weather. Install Windy.com — check the hourly forecast. Mornings are usually clear. Schedule beach time and excursions for the first half of the day, and indoor activities for the afternoon.
Enjoy the emptiness. In May there are 70% fewer tourists than in January. Beaches are empty, restaurants have no queues, roads have no traffic. This is a different Phuket — calm and authentic.
Choose a hotel with a good pool. On rainy days the pool is your salvation. Swimming in a heated pool under a tropical downpour is one of the best feelings. Many 4–5 star hotels have indoor pools.
Eat at the markets. In the low season tourist restaurants often close, but markets run always. Malin Plaza (Patong), Chillva Market (Phuket Town) — dinner for 100–200 baht.
Do not fear the rain. A tropical downpour is warm (27°C), lasts an hour or two, and then it is over. This is not a cold European rain. Many people actually enjoy walking in it.
