How is the Weather in Phuket in July?
Phuket weather is more rainy in July than in June. The monsoon, or low season, has definitely started, and you can expect the sea to be rough and the sky to be cloudy. But like every month of the low season in Thailand, you might get quite a few sunny days. However, one pattern happens every year in Phuket: the bad luck weeks. Read more about Phuket weather.
Every year during the rainy season, the weeks alternate nicely between clear skies, cloudy days and a few rainy days, usually in the evening or at night. But there are bad luck weeks with lots of rain, non-stop for 3 to 5 days. It’s not frequent, and no one likes those weeks, but it has to happen. Nature needs it.
During the rainy season, I recommend booking a hotel with a nice swimming pool so you can sunbathe and swim as much as you want even when the sea is rough. It is really important to respect the swimming flags. If the flag is red, don’t swim! Even if you consider yourself an excellent swimmer, you will be surprised by how strong the current is. If you really want to swim in the sea, try Tri Trang Beach near Patong. It is usually calmer than other beaches, but use your common sense.

Sea Condition in July
Rough seas and stronger waves are common on the west coast, increasing the risk of undertows. Swimmers should be extra cautious, especially at open beaches. Red flags mean no swimming. East coast beaches like Ao Po and Cape Panwa tend to be calmer.
What to Do in Phuket in July
Just like every month of the rainy season in Phuket, you can take advantage of the many options available for both sunny and rainy days. Bookmark my list of things to do in Phuket when it rains. Enjoy the sunny days on the beach as much as you can in case the weather changes. A spa treatment is always the first activity that comes to mind when the sky is threatening, so book as soon as possible, whether in your hotel or an independent spa.
Jungceylon in Patong is a popular place to spend a rainy day. Or get a ride to Central Phuket to spend the day shopping and browsing, visit the giant aquarium or watch a movie.
Surfing in July
July is a good month for surfing in Phuket, mainly at Kata Beach and Kalim Beach, while kitesurfing is best at Nai Yang Beach. The monsoon swells bring consistent waves, and surf schools operate throughout the season.
Island Tours
Tours to nearby islands operate normally unless a serious storm is announced. A day trip to Phang Nga Bay is always a great day out. The scenery is even more impressive with big clouds above the limestone cliffs, and you will glide between them aboard a comfortable covered boat. Phi Phi Islands ferries run daily, though speedboat tours may be cancelled on rough days.
Low Season Benefits
Prices in Phuket are lower, and bargaining is easier and more rewarding than in high season. Keep in mind that locals are also trying to make a living. If you are in Patong and not in a rush, shop at OTOP market or Chillva Market rather than on Bangla Walking Street. You will get much better prices!
Hotels are much cheaper and will give you their best rooms if you ask. Driving around Phuket is easy, and traffic is a lot less annoying than in high season.

Time-lapse of Each Day of July 2025
Considering visiting Phuket in July and worried about how much rain to expect? Each year is different, and there will be some rain. It doesn’t rain every day, and there are some amazing weeks! However, there will be a couple of ‘bad luck weeks.’ There is nothing anyone can do about these, and there is no way to predict when they will occur. I gathered all the timelapses from July last year, so you can browse each day to get an idea of what July can look like.

What to Pack for July
Pack light clothing as it never gets cold in Phuket. T-shirts, shorts, skirts and sandals are all you need. Add a light raincoat and a compact umbrella that you can carry around easily. All of these can be bought anywhere on the island if you forget them. Waterproof sandals are useful when the streets get wet. A waterproof bag for your phone and camera is essential. High-SPF sunscreen is still needed since the UV remains extreme even on cloudy days. Read more in my full packing guide for Phuket.
Insider Tips
July is firmly in the monsoon season, but don’t let that put you off. The rain rarely lasts all day. Most showers come in the afternoon or evening, leaving mornings sunny and clear. Plan outdoor activities early in the day.
The ‘bad luck weeks’ are real. Every year, there are one or two weeks where it rains nonstop for 3 to 5 days. Nobody can predict when they will happen. If you hit one, embrace it. Book a spa day, go shopping, or try a cooking class. The island still has plenty to offer.
Book a hotel with a good pool. The sea on the west coast is usually too rough for swimming in July. Red flags are common at Patong, Karon, Kata and other west coast beaches. East coast beaches like Ao Po, Cape Panwa and parts of Rawai stay calmer if you really want to swim in the sea.
Hotel prices are at their lowest. This is the month to book that luxury resort you couldn’t afford in December. Many hotels offer upgrades, free breakfast and spa credits to attract guests.
Surfing is at its best. The monsoon swells bring consistent waves to Kata, Kalim and Surin. If you’ve wanted to learn, July is a great time. Surf schools have more availability than in high season.
The best way to check real conditions is my daily weather timelapses. Each video shows a full day compressed into one minute. Nothing helps more than seeing what a typical July day actually looked like last year.
July Weather Through the Years
July follows a predictable pattern, and the month follows a predictable pattern. It will rain. The sea will be rough. But there will also be beautiful sunny days, sometimes for a week straight.
What I’ve noticed over the decades is that the ‘bad luck weeks’ are unavoidable, but they’re also short. In 30 years of Julys, I can count on one hand the times it rained non-stop for more than a week. Usually, it’s 3 to 5 days, then the sun returns.
The biggest change is how the island handles the monsoon season now. When I first arrived, the low season was genuinely quiet. Some restaurants closed, and some hotels reduced staff. Now Phuket has become a year-round destination. Almost everything stays open. The infrastructure is better. Roads drain faster. Hotels have covered areas and great pools.
July has also become popular with surfers and kitesurfers. The waves that used to make July unappealing to swimmers are exactly what draw the board sports crowd. Kata Beach in July feels completely different from Kata Beach in January.
If you’re coming in July, my advice is simple: expect some rain, book a hotel with a pool, and enjoy the lower prices and quieter beaches. You might get lucky with perfect weather. If you don’t, the island still has plenty to offer.
