Greece experienced its second hottest month of July in the past 15 years.  The month was marked by prolonged heatwaves, especially between the 14th and 28th July, with average maximum daily temperatures consistently exceeding seasonal highs across the country.  Although Northern and Central Greece ranked the second hottest since 2010, when 53 meteorological stations started operating across the whole country, the Peloponnese saw their third hottest July.  Not many people can forget last year's high temperatures in Kranidi hitting 43.9°C, with Didyma recording 42.7°C.  July's sweltering conditions triggered alerts, strained infrastructure and raised public health concerns, particularly when temperatures climbed above 45°C in some areas, closing the Athens Acropolis during the midday period.

The data underscores the growing impact of climate change across the Mediterranean regions, with July 2025 serving as a stark reminder of what increasingly appears to be the new normal for Greek summers.

According to the European Copernicus Observatory, July 2025 ranked as the third warmest month in Earth's history.  On average, July 2025 was 1.25°C warmer than any July in the pre-industrial era (1850-1900).  This figure remains just below the 1.5° Celsius target of the U.N. Paris Agreement of 2015, a threshold that has been exceeded in most months over the last two years.

• Extreme heatwaves pushed temperatures above 50°C in the Gulf, Iraq, and for the first time on record, in Turkey.
• A public institute attributed more than a thousand deaths to the heat in Spain, 50% higher than in 2024.
• Torrential rains led to catastrophic floods that killed hundreds of people in China and Pakistan.
• Wildfires scorched thousands of acres of forests, primarily in Canada.
