Friday, July 4th, 2025, is expected to be a challenging day in many regions of Greece due to high temperatures and strong winds that have prompted an orange alert across several areas. Temperatures are forecasted to reach up to 38 degrees Celsius, increasing the risk of wildfires, especially when combined with powerful gusts. Authorities are on high alert and prepared for any emergency.
Among the regions placed under orange alert is Attica, where fire danger levels have been classified as category 4 — the highest level of risk. According to the Fire Danger Forecast Map issued by the General Secretariat of Civil Protection under the Ministry of Climate Crisis and Civil Protection (civilprotection.gov.gr), other high-risk zones include Kythira, Evia, parts of the Peloponnese, and islands in the Northern Aegean such as Chios, Samos, and Ikaria.
The weather today will remain mostly clear and sunny across the country, but local heatwaves are expected. Inland mountainous areas may see cloud development during the hottest hours. Temperature ranges vary by region, with maximums reaching up to 39°C in western Greece and 37°C in inland areas. Coastal regions and islands will experience slightly milder conditions, though eastern Aegean islands could also see temperatures climb to 37°C.
Winds in the Aegean Sea are blowing from northern directions at intensities of up to 6 Beaufort, particularly in southern areas, while the Ionian Sea sees northerly to northwesterly winds of 3-5 Beaufort. In Attica, expect sunny skies and temperatures between 27°C and 35°C, with winds ranging from 3 to 5 Beaufort.
Meteorologists warn that even worse conditions are coming next week, as a new heatwave is set to hit Greece starting this weekend. The mercury is expected to soar rapidly, possibly reaching extreme highs of 41–43°C, surpassing previous heat records. This intense wave is predicted to last at least five days, further elevating fire risks.
Meteorologist Yiannis Kallianos noted that while temperatures might drop slightly after July 11th, wind activity is likely to increase again, maintaining dangerous conditions. Residents and authorities alike are urged to remain vigilant and take necessary precautions.
