Summer in Alanya lasts from June through September. In July and August, daytime air temperatures climb above 30 °C (as of 09/2026, vacationweathermap.com). The sea is at its warmest during these months, so you can swim even late in the evening.
The downside of summer is the heat and the crowds. The peak falls in the second half of July and all of August, when the beaches are packed and the sun burns from early morning.
Autumn starts with a warm September. The month's average temperature stays around 25 °C, dropping to 20 °C in October (as of 09/2026, Holiday-Weather, September and October). The sea cools more slowly than the air, so you can keep swimming until November.
Winter here is mild but wet. Precipitation comes in waves, with the most in January (as of 09/2026, Holiday-Weather, winter months). The sea in February is the coldest of the year (as of 09/2026, climate-data.org, water minimum).
In spring the air warms up quickly, while the water catches up with a delay. By late May the sea is already suitable for swimming, and the beach season opens with it (as of 09/2026, wohinwann.de about the sea).
The sea: when the water is comfortable for swimming
The average annual water temperature in Alanya stays at 22.6 °C (as of 09/2026, climate-data.org on the average). In winter the sea cools to about 17 °C, the yearly minimum (as of 09/2026, February water minimum). This water is invigorating, but not suitable for long swims.
You can swim long and comfortably from June through October. The peak comes in August, when the water reaches 28-29 °C (as of 09/2026, wohinwann.de, water temperature). In September and October it is still warm: the sea releases heat more slowly than the air cools.
In practice, this means the following. If the main goal of your trip is the sea, choose June, September, or the first half of October. In early May and November the water is noticeably cooler, and such swims are for the hardy.
Beaches in high season fill up from early morning. Come by 8:00 or after 17:00, and you will have a free spot by the water and soft sun.
Best time to visit
Alanya has three good windows, and each solves its own problem.
May and June: warm sea without the heat
Late May opens the swimming season (as of 09/2026, swimming season in Alanya). The water is already suitable for swimming, and the air has not yet heated up to 30 °C. Beaches at this time are less crowded than in August.
This is the best option for you if you are coming for the sea and do not want to swelter in the heat.
September and October: water still warm, fewer people
In September and October the air is noticeably cooler than in summer (as of 09/2026, Holiday-Weather data). The sea holds its warmth and remains suitable for swimming until November (as of 09/2026, wohinwann.de on the swimming season).
You get warm water without the heat and without the summer crowds. This is the most comfortable time for walking around the fortress and the promenade.
January and February: walks instead of the beach
In winter the air is cool, and the sea is at its coldest of the year (as of 09/2026, climate-data.org, winter sea). The beach takes a back seat, but the city looks its best without the summer bustle.
Heat, rain and humidity
In summer the heat is amplified by humidity. Plan your walks before 11:00 and after 17:00, and you will avoid the harshest sun. In July the sun shines for up to 13 hours a day (as of 09/2026, Holiday-Weather, sun in July), so you need sunscreen and a hat even in the shade of umbrellas.
In winter the main factor is rain. In January, 227 mm of precipitation falls (as of 09/2026, rain in January), making it the wettest month of the year. Rain comes in waves, with clear and warm days in between.
Humidity is high all year round. Because of it, heat feels harder to bear than in dry regions, and a cool evening feels warmer.
What to pack by season
For summer, light clothing is enough, but there is a mandatory set.
- For July and August: SPF 50 sunscreen, a hat, a water bottle and shoes for cobblestones.
- For May, September and October: long-sleeved t-shirts, a windbreaker for the evening, a swimsuit.
- For winter: a warm sweater, a waterproof jacket and an umbrella, January rains are heavy.
- For excursions: closed shoes and a power bank, a day on the route turns out long.
- From our travel experience: take a second pair of shoes, wet cobblestones are slippery.
