Weather in Istanbul in August 2025

In August, Istanbul experiences the height of summer with hot and dry weather dominating the cityscape. The average temperature during August hovers around 24°C (75.2°F), with daytime highs often reaching 28°C (82.4°F). While these temperatures might be enjoyable for those seeking warmth, they can also make sightseeing and outdoor activities quite challenging, especially during the midday hours when the sun is at its strongest.

With approximately 10 hours of sunshine per day, August is a sun-lover dream. The clear blue skies allow for plenty of opportunities to explore the city's iconic landmarks, ancient sites, and stunning architectural marvels. Whether you're visiting the world-famous Hagia Sophia, marveling at the stunning Blue Mosque, or descending into the mystical depths of the Basilica Cistern, you'll be treated to breathtaking historical wonders under the brilliant sun.

The warm sea temperatures of around 19°C (66.2°F) also make it an excellent time to enjoy Istanbul's beautiful beaches and coastal areas. Many locals and tourists alike take advantage of this weather to relax and unwind at the beach clubs along the shores of the Sea of Marmara or the Black Sea.


However, the heat and humidity can be quite intense, especially for those not accustomed to such weather. Humidity levels of around 70% add to the discomfort, making it essential to stay hydrated and take breaks in the shade when needed. Carrying a water bottle and wearing light and breathable clothing are highly recommended.

While Istanbul is generally not known for heavy rainfall, August is one of the driest months of the year. The city typically receives only about 20mm of rainfall spread over four days. Any showers that do occur are usually brief and accompanied by the occasional thunderstorm, which can be a welcome respite from the heat.

It's worth noting that Istanbul's northern regions within the province experience slightly higher rainfall levels compared to the city center. If you're planning to explore the surrounding areas, be prepared for slightly wetter conditions. Check out one of the best seashore neighborhoods of Istanbul: Kilyos.


August is a fantastic time to visit Istanbul if you enjoy hot and sunny weather. The city is alive with energy, offering a wide range of cultural events, festivals, and outdoor activities.
