September wrapped up on a wet, autumn note in Athens. Greece’s national meteorological service (EMY) called for showers and a few isolated thunderstorms in Attica and Macedonia, with the Athens urban area seeing more cloud and brief, light bursts of rain. The morning update on 30 September 2025 also flagged the return of northerly winds over the Aegean.
How long will the unstable weather last?
EMY’s forecast focused on Tuesday, 30 September, and kept the day on the unsettled side. It did not give a clear cut-off beyond that period. The Cyclades and the Dodecanese were the exceptions, with mostly fair weather, while elsewhere clouds at times thickened and brought local showers.
What about visibility and safety?
EMY added that visibility could drop in spots during the early morning and evening, especially across the mainland. With wet roads likely in parts of Attica and central Greece, drivers and commuters should expect slower traffic at times. There were no special advisories in the source update.
Where will showers be most likely?
Showers were on and off across the north and east of the mainland, the Sporades and Evia. Macedonia and Thrace were in for periods of thicker cloud with light, spotty rain. In contrast, the Cyclades and Crete were expected to see only a few clouds, while the eastern Aegean islands and the Dodecanese kept largely fair skies.
What does it mean for Athens residents?
Across Attica, including Athens, the forecast called for more cloud in spots and brief, light showers; if you’re heading out, a small umbrella could be handy. Winds were variable near 3 Beaufort, and temperatures were expected between 16°C and 24°C. It’s very much that first taste of autumn EMY pointed out for the end of September.
Wind and temperatures: what to expect?
Northerly to northwesterly winds held at 3-4 Beaufort in many places; in the southeastern Aegean they picked up to 4-5, and locally 6 in parts of the Dodecanese. Daytime highs mostly reached 23-25°C, with Crete and the Dodecanese locally touching 26°C. Thessaloniki was set for about 14-23°C and a chance of light, local showers.
