A new heatwave is forecast to hit Greece in the coming days, with temperatures expected to soar to as high as 43°C (109°F) in some areas. According to meteorologists, the most intense days of this heatwave are likely to occur between Monday, July 7 and Thursday, July 10.

The current heat affecting much of Central Europe is expected to ease soon, giving way to stormier conditions. However, Greece will remain under the influence of very warm air masses, especially from the weekend onward, leading to dangerously high temperatures nationwide.

Forecast Highlights

According to the latest national forecast, much of Greece will experience mostly clear skies throughout the day, although some parts of the country may see localized cloudiness and short-term showers, especially in mountainous regions during the afternoon and evening hours.

Wind conditions will vary, with light winds (3–4 Beaufort) in the west and stronger northerly winds (up to 7–8 Beaufort) expected in parts of the Aegean Sea, especially by the afternoon.

Temperature Overview

  • Northern mainland areas are expected to reach 34–35°C.
  • Central mainland regions, including Thessaly, may experience highs of 36–37°C.
  • Island regions such as the eastern Aegean, the Dodecanese, and southern Crete will see temperatures between 33–35°C.
  • Attica (Athens region) is forecast to reach 34–35°C, slightly cooler along coastal areas.
  • Thessaloniki will see a range of 24–32°C, with chances of light rain in the morning and localized showers later in the day.
  • Western Greece, including Epirus and the Ionian Islands, will face heat up to 36–37°C, particularly inland.

Despite a slight drop in temperature in some eastern areas today, the upcoming days are expected to bring more intense heat. Authorities are warning residents to prepare for extreme conditions and take necessary precautions, particularly the elderly and vulnerable.

Expert Warnings

Public health officials continue to emphasize the dangers of prolonged heatwaves, often described as “silent killers.” Experts stress the importance of hydration, avoiding outdoor activity during peak hours, and seeking air-conditioned environments whenever possible.

Greece’s national weather service and local authorities remain on alert as the country enters another period of extreme summer temperatures, with high winds in the Aegean possibly compounding fire risks.
