By August 24, the wildfire risk in Greece remained critical, with a ‘Red Code’ alert (category 4) issued for Attica, including Kythira, and several regional units including Phthiotis, Boeotia, Evia (including Skyros), the Peloponnesian regions of Corinthia, Argolis, and Laconia, as well as the Cyclades and North Aegean islands such as Lesvos, Chios, Samos, and Ikaria. This status triggered the ‘full mobilization of the National Mechanism,’ deploying personnel, vehicles, and technical resources.

For Tuesday, August 25, the risk level shifted for several areas, with many regions placed under category 3 (high risk). This elevated risk includes Attica, Crete, the Ionian Islands, and parts of mainland Greece such as Thessaly and Macedonia. 

Concurrent with the wildfire warnings, meteorologists reported a significant heatwave, with temperatures in Attica expected to approach 40°C. In response to the ongoing threat, the Fire Service has activated its second stage of operational readiness, placing personnel in affected areas on partial standby. Authorities continue to advise citizens to avoid activities that could spark fires, such as burning dry grass, using power tools like circular saws, or operating outdoor grills.
