According to MEGA meteorologist Christina Rigou, winds will ease today. In fire-stricken Achaia, as well as Filippiada, winds will blow between 3 and 5 Beaufort, while in Chios, also affected by wildfires, winds will be up to 4 Beaufort. Significant wind strengthening is expected on Saturday, August 16, with stormy winds reaching up to 8 Beaufort in Lemnos, Samothraki, southern Evia, the northern Cyclades, and Attica. Winds will weaken again from Sunday, August 17 onward.

Giannopoulos: Winds to strengthen again on Saturday
As forecaster Panagiotis Giannopoulos noted, the Aegean will still have winds up to 7 Beaufort, but winds in Chios – where there is increased concern about the wildfire front – have eased. On Saturday, they will strengthen again, reaching 8 Beaufort in the Aegean, without, however, causing travel bans or significant disruption. Temperatures will also be excellent, with cooler conditions across the country. According to Giannopoulos, there are no signs of a heatwave until at least August 23.
