Sedef Adası Plajı: Weather Today

📅 Friday, April 24, 2026

Summary
Full Forecast

Today is a challenging day for a traditional beach trip, as the air remains quite brisk and the water is far too cold for swimming. While you will enjoy plenty of bright sunshine throughout the day, the maximum air temperature will only reach 15.2 °C, making it better suited for a scenic walk along the shore rather than sunbathing. Be mindful that the UV Index is 6.65, so protective clothing or sunscreen is recommended if you are spending time outdoors. The sea temperature is a chilly 11.1 °C, and with the water being completely calm, it serves as a beautiful backdrop for a stroll. While the breeze is noticeable at times, it should not disrupt your plans if you dress warmly and focus on enjoying the coastal views.
