Other regions, including the Ionian Islands, Epirus, the North Aegean, and parts of the South Aegean, were placed under Category 4 (Orange) high risk alerts. To mitigate these risks, authorities implemented bans on movement and presence in various forested areas and Natura sites, particularly in Crete, the South Aegean, and Western Macedonia. Violations of these restrictions or fire safety regulations can result in administrative fines of 300 euros and criminal penalties.

Category 4 very high risk was expected for Attica, Central Greece (Evia), the North Aegean (including Lesvos, Chios, Samos, and Ikaria), the Cyclades, Kalymnos, Kos, and Laconia. Strict preventive measures remained in place, including movement bans in Western Macedonia, East Attica, Zakynthos, and parts of Thesprotia. In the Municipality of Agiou Nikolaou, access to the Kritia Gorge and several forests was prohibited.
