When to go to Belek
💡 In short:
- Best time for the beach: late May, June, September and October.
- Peak heat: July and August, average daytime high around 36 °C.

Belek lies in the Mediterranean climate zone Csa under the Köppen classification, with an average annual temperature of around 18.7 °C (as of 09/2026, climate-data.org). Summers are long and dry, winters mild and rainy. The area gets roughly 304 dry days a year (as of 09/2026, Belek summary).
The rhythm of the resort is set by the sea and golf. From June to September everything revolves around the beach and pools, while from November to March people come to play golf and explore ancient cities. In the low season the resort does not empty out, and you will find things to do beyond the beach.
In spring the weather changes fast. In March the daytime high is around 19 °C, in April 21 °C, and by May it is already 28 °C (as of 09/2026, monthly norms for Belek). That is why late spring appeals to those who want warmth without exhausting heat.

Average values over several years: 09/2026, based on the monthly temperature table and average coastal water temperature.
In the table, day and night show the average monthly high and low, not one-off peaks. The "Water" column shows the average sea temperature near the shore, and the "Rain" column counts the average number of days with precipitation. We cross-checked the data against open statistics from the Turkish meteorological service (as of 09/2026, MGM).
The first warm days arrive in March, but swimming is comfortable from mid-May. December and January are the rainiest months. Frost on the coast is almost unheard of.
Pay attention to the water, not just the air. In May the air is already warm, but the sea is only starting to heat up, so with kids it is better to wait a couple of weeks.
Swimming season and water temperature
The swimming season in Belek runs from May through October (as of 09/2026, average water temperature). Until December the water does not drop below 20 °C, but from November on it rains often. In summer the sea warms to an average of 27.7 °C, in autumn it stays around 25.6 °C, in winter it drops to 18.6 °C, and in spring it rises again to 18.9 °C.
The peak comes in August, when the water reaches about 30 °C, and September is almost as warm (as of 09/2026, monthly water values). In May the water is around 21 °C, which is a comfortable threshold for adults.
The beaches in Belek are sandy and wide, some have Blue Flag status, and the resort itself is considered family-friendly. The entry into the water is gentle, so you can swim with kids without worry. Sun loungers and umbrellas are usually included in hotel infrastructure; on public stretches you pay for them separately.
- The catch: in December the water is around 20 °C, so swimming is comfortable only on a warm day and in shallow water.
Heat, humidity, and wind
July and August are the hardest months to handle. The average daytime high stays around 36 °C, and on some days the air heats up above 40 °C (as of 09/2026, weather reports for Belek). Humidity near the sea is high, so the heat feels stronger than in a dry climate.
Plan your day properly. Go to the beach before 10 a.m. and after 5 p.m., and stay in the shade or by the pool during the middle of the day. Bring light cotton clothing, a hat, and plenty of water. Air conditioning is essential in summer; without it you will sleep poorly.
The sea breeze softens the heat, but it does not protect you from the sun. In July and August the sun shines for 12 hours a day (as of 09/2026, sunshine hours by month). In September the heat eases while the sea stays warm, and many people choose exactly this month.
Autumn and mild winter
September and the first half of October suit those who do not handle extreme heat well. The sea stays warm, the air in September holds around 34 °C, and in October it drops to about 28 °C (as of 09/2026, monthly averages for Belek). The beaches gradually empty out, and hotel prices come down.
The rainy period starts in November. November has about 9 rainy days, December 11, and January remains the wettest with 12 rainy days (as of 09/2026, rainy day statistics). Do not plan a beach vacation in these months.
Winter here is mild: 15-17 °C by day, 6-8 °C at night. Swimming is chilly, but golf clubs are open and the ancient cities nearby are accessible. If you are coming for sightseeing and peace and quiet, winter will suit you.
- The catch: from November through March it rains often, and the short daylight hours leave little time for walks.
What to see near Belek
The weather almost always allows a day trip to another city, since two major centers are close to Belek: Antalya and Side (according to the Belek resort review, as of 09/2026). The resort itself is not rich in landmarks, so trips to neighboring cities are a normal part of a vacation here.
In Antalya, it is worth strolling through the old town of Kaleiçi with its narrow streets and Ottoman houses. In Side, the ancient amphitheater, the Temple of Apollo, and colonnades right by the water have been preserved. You can easily combine both cities with the beach.
In summer, head out in the morning: the heat intensifies after lunch, and in July and August it takes a toll on your well-being. In winter, excursions run at any time of day. It is convenient to compare programs and book excursions on GetYourGuide in advance.
⁉️🤔 Frequently asked questions
When is the sea warmest in Belek?
The peak is in August: the average water temperature is around 30 °C (as of 09/2026, monthly averages). In September the sea cools only slightly, with water staying around 29 °C, so the shoulder season is almost as good as summer. By late October the water drops to 26 °C, but swimming is still comfortable. For families with children, September is often the best choice.
Can you swim in May?
Yes, but the second half of the month is better. The average water temperature in May is around 21 °C (as of 09/2026, monthly water statistics), which is fine for adults but may feel cool for children. The air warms up to 28 °C, the beaches are half empty, and hotel prices are lower than in July. Bring warm clothes for the evening: it gets down to about 15 °C at night.
When are there the fewest tourists in Belek?
The quietest time is from November through March, plus April and the first half of May. The summer rush starts in June and lasts until late September. In the low season you get empty beaches and noticeably lower prices, but be prepared for rainy days. In winter the resort runs on golf and excursions.
How hard is the heat to handle in July and August?
It is hard, especially in the first few days. Humidity by the sea is high in these months (as of 09/2026, July and August norms). The sea breeze, air conditioning, and a sensible schedule help: beach in the morning and evening, shade in the afternoon. Older people and small children are better off avoiding these months.
How long is the drive from Antalya Airport?
Antalya Airport is close to the resort, the drive takes about 40 minutes (as of 09/2026, hotel transfer information). Book a transfer in advance or take a taxi outside the terminal. In summer, allow extra time: the road is busy in high season, and in July and August you can get stuck in traffic.
In short: what to book
If you want a warm beach without exhausting heat, go for late May or September. If you want the warmest sea, plan for August and September and be ready for high humidity. If you are coming for golf, excursions, and peace and quiet, choose the period from November through March.
