July may have started with a warm footprint, but a marked shift in weather is expected over the next 24 hours — bringing cooler air, scattered showers, and gusty winds. Meteorologists warn that atmospheric instability has already begun and will intensify over the coming three days, with localized rain, thunderstorms, and strong gusts anticipated across several regions.
High Temperatures Hold Until Friday
Temperatures will remain elevated through Friday, 3 July 2026 — reaching up to 37°C in parts of mainland Greece. In Attica, cloud cover is expected during the afternoon and evening, especially over western and northern areas, with highs of 34°C and winds at 2–4 Beaufort. Thessaloniki will also see isolated thunderstorms, with temperatures peaking at 33°C.
Saturday Brings Widespread Rain and Cooling
A significant drop in temperatures begins Saturday, when rain is forecast across much of the mainland — including Euboea and the Sporades. Winds, currently light, will strengthen from Saturday onward, reaching up to 8 Beaufort in the Aegean by Sunday.
