Scorching Heat Returns Across Turkey: August 23, 2025 Weather Forecast

City-by-City Breakdown with Special Focus on Istanbul, Muğla, and Antalya

No Rain, Just Blazing Sunshine Across the Country
According to the latest data from the Turkish State Meteorological Service, Turkey is in for another day of intense summer heat. Rain is not on the radar for any region today, with clear skies dominating from the northwest to the southeast. Temperatures are well above seasonal averages, and the heat is expected to intensify in major cities and holiday destinations alike.

Heatwave Grips the Nation
As August winds down, Turkey is experiencing a powerful late-summer heatwave. Inland regions like Central Anatolia are seeing highs around 35°C, while Southeastern Anatolia is pushing past 40°C. The entire country is under the influence of dry, hot air, with no relief in sight for the weekend.

Light Winds, Little Relief
Winds are expected to come mostly from the north and west today, blowing lightly with occasional moderate gusts. Unfortunately, these breezes won’t be strong enough to offset the intense heat, especially in areas like the Mediterranean coast and the southeast.

Spotlight on Key Cities

Istanbul: Hot, Dry, and Mostly Clear
Istanbul will experience a typical summer day — hot and sunny, with only a few light clouds expected later in the day. The high will reach 31°C. While not extreme by inland standards, the urban heat and humidity will make it feel warmer, especially during peak afternoon hours. It’s a good day to stay near the water or in shaded areas if you’re in the city.

Muğla: High Heat in the Heart of the Aegean

Muğla and its surrounding popular tourist areas — including Bodrum, Marmaris, and Fethiye — are baking under the sun. While Muğla city itself isn’t listed specifically, surrounding cities like Denizli and Manisa are seeing highs around 39°C, and similar temperatures are expected in the region. Visitors and residents should avoid prolonged sun exposure and hydrate frequently.

Antalya: Coastal Calm, Comfortable but Still Hot

Antalya enjoys some coastal moderation, but temperatures will still reach up to 31°C today. Clear skies and minimal cloud cover will make for perfect beach weather — but also increase the risk of sunburn and heat exhaustion. UV levels remain high, so sunscreen and shade breaks are a must.

Turkey is baking under widespread heat, with no immediate cooling in sight. Cities like Istanbul may not be hitting the 40s, but urban conditions make the mid-30s feel oppressive.

Whether you’re in a coastal resort or inland city, it’s crucial to stay cool, stay hydrated, and be mindful of the risks that come with prolonged exposure during such high temperatures.
