Showers and thunderstorms were recorded today across western Greece — particularly heavy in Zakynthos, Kefalonia, and western Peloponnese — and are expected to move gradually eastward on Thursday, affecting the central, southern, and eastern Aegean as well as the Dodecanese.

According to meteorologist Theodoros Kolydas, unsettled conditions will persist on Friday in the western parts of the country and the eastern Aegean, while the weather is expected to improve over the weekend across most regions. A new deterioration is forecast from Tuesday, starting in the north.

Kolydas noted that temperatures will remain stable until Saturday, then rise significantly on Sunday and Monday, reaching 26–27°C, and locally up to 29°C in northern Crete due to southerly winds. A marked drop in temperature is expected on Tuesday with the passage of a Balkan cold front.
