Temperatures to Reach 40 Degrees Celsius in Greece Amid Heatwave; Some Areas May See Storms

Greece is set to experience a significant heatwave, with temperatures expected to soar to 40 degrees Celsius in several parts of the country. The forecast indicates sunny skies across most regions, though some inland mountainous areas might experience brief showers and isolated thunderstorms during the afternoon hours.

The heat is expected to intensify across the mainland, with temperatures potentially reaching 35 to 36 degrees Celsius. Thessaly, in particular, could see highs of up to 37 degrees Celsius. Coastal areas and islands will likely experience slightly milder conditions, with maximum temperatures ranging from 33 to 35 degrees Celsius.

Winds in the Aegean Sea will be moderate, blowing from the north-northwest at 4 to 6 Beaufort. Elsewhere, winds will be variable and light, shifting to west-northwest up to 5 Beaufort in the afternoon in western regions.

Looking ahead to Monday, July 13, 2026, the weather is expected to remain generally clear. However, temporary clouds may form over the mainland's mountainous areas in the afternoon, potentially bringing local rain or showers. The heatwave is a significant concern for the region, impacting daily life and potentially increasing the risk of wildfires.
