Rainfall will begin in the morning over the northern Ionian Sea and Epirus—northwestern regions of Greece bordering Albania—where scattered thunderstorms may also develop early in the day. By midday, light to moderate rain is forecast across the rest of western Greece, as well as parts of central and northern regions.
By evening, conditions will begin to improve from the west, and overnight any remaining rainfall will gradually come to an end. Clear skies are expected to continue across the rest of the country.
Temperatures will decline slightly, reaching around 28–29°C in western and northern Greece, up to 30°C in other regions, and as high as 31°C in eastern Central Greece and the Peloponnese peninsula in southern Greece.
In terms of wind conditions, southerly winds in the Ionian Sea will initially blow at 4–6 Beaufort, gradually shifting to northwesterly winds with a weakening trend. In the Aegean Sea, southwesterly winds of 5–6 Beaufort are expected, locally reaching up to 7 Beaufort in southwestern sections.
In Athens (Attica region), weather conditions will remain mostly clear with occasional thin cloud cover, which may increase intermittently after midday. Temperatures will range between 20°C and 31°C, with southwesterly winds up to 4 Beaufort, strengthening over surrounding sea areas to 5–6 Beaufort from the afternoon.
