How is the Weather in Phuket in April?
The weather in Phuket in April remains beautiful and clear. The sea continues to be calm, and the water is as warm as a bath. April is the hottest month of the year in Phuket, and temperatures can reach some of the highest peaks. If you travelled on a short budget and picked one of the few hostels without air conditioning and just a fan, you better be ready for some hot nights. All hotels in Phuket are well prepared, and air conditioning is expected to provide comfortable temperatures in your room. Read more about Phuket weather.

Sea Condition in April
The hot weather continues, and the sea remains mostly calm. However, occasional afternoon storms can create short-lived rough conditions. The sea temperature reaches 30°C, making it the warmest month for swimming. April is the last full month before the Similan Islands close in mid-May, so plan your island trips now if that’s on your list.
What to Do in Phuket in April
Beat the Heat
April is scorching. The best strategy is to plan outdoor activities for early morning or late afternoon. Between 11 am and 3 pm, the sun is intense. Here are some ways to stay cool:
Water Parks: Andamanda Water Park and Splash Jungle Water Park are perfect escapes from the heat.
Shopping Malls: Air-conditioned malls like Central Phuket and Jungceylon offer a welcome break from the sun.
Island Hopping: April is your last chance to visit the Similan Islands before they close in mid-May. The sea breeze on boat trips provides relief from the heat.
Early Morning Beaches: Arrive at the beach before 10 am. The sand is cooler, parking is easier, and you’ll have more space to yourself.
Events and Festivals in April
Songkran Festival 2026
Songkran 2026 dates: 13-15 April (official public holiday). In Phuket, celebrations on Bangla Road and Patong Beach often start a day early and continue a day later.
April is so hot each year, but it is also the occasion to celebrate the famous Songkran festival, where people shower each other copiously for several days (and nights). It’s fun for most, but if you don’t like getting wet and partying wild, consider avoiding the Songkran week.
What to expect: Water fights everywhere, especially along Bangla Road and the beach road in Patong. Hotels and restaurants get splashed. Traffic slows to a crawl. Prices for accommodation spike during this week, so book early.
What to bring: Waterproof phone pouch (essential), quick-dry clothes, waterproof bag for valuables, sandals with grip, and sunscreen. Leave expensive cameras at the hotel.

What to Pack for April
Pack as light as possible. You’ll want loose, breathable clothing in light colours. Cotton and linen work well. Bring a hat or cap for sun protection, quality sunglasses, and high-SPF sunscreen. A small umbrella or light rain jacket is useful for afternoon showers. Sandals are fine for most places, but bring one pair of closed shoes for temples or nicer restaurants. If you plan to join Songkran, pack quick-dry clothes and leave your best outfits at home. Read more in my full packing guide for Phuket.
Insider Tips
April is the month when locals complain the most about the heat. Even people who have lived here for decades find it intense. The trick is to adjust your schedule. Do your sightseeing early in the morning or after 4 pm. Use the hottest hours for lunch, a spa, or shopping in air-conditioned malls.
If you’re visiting during Songkran week (13-15 April), expect everything to be busier and pricier. Book your hotel well in advance. Traffic in Patong becomes chaotic, and getting a taxi or Grab can be difficult. Many locals leave Phuket to visit family upcountry, so some smaller restaurants close for a few days.
The Similan Islands close in mid-May and won’t reopen until October. If you want to see them, April is your last chance for the season. Book your trip early in the month before the monsoon swells start building.
Afternoon storms can appear suddenly in late April. They’re usually short but intense. If you see dark clouds building, head for shelter. The good news is that these storms cool things down and clear the air.

April Weather Through the Years
I’ve been in Phuket every April since 1994, and the heat has definitely increased over the decades. When I first arrived, April was hot but manageable. Now it feels oppressive some years, with temperatures pushing higher and humidity building earlier in the month.
The pattern has also shifted. April used to be reliably dry with occasional afternoon clouds. Now I see more rain in late April than I remember from the 1990s. The monsoon seems to be creeping earlier each year. Some Aprils are still perfect; others feel like May already arrived.
Songkran has changed too. The water fights used to be a three-day affair mostly in town centres. Now the whole island joins in, and celebrations start earlier and end later. Patong during Songkran week is a completely different experience from Patong the rest of the year. Whether that’s good or bad depends on what you’re looking for.
My advice: if you can choose your dates, aim for early April (before Songkran) or late April (after the crowds leave). The weather is similar throughout the month, but the atmosphere changes dramatically around the festival.
