Wednesday, November 19, brings another day of unstable weather across Greece, with rain and thunderstorms affecting several regions. The Ionian Sea, the western mainland, northern Macedonia, Thrace and the southern Peloponnese will see the most active conditions. Elsewhere, cloud cover will dominate with the chance of brief, light local showers. Atmospheric dust levels will remain elevated, reducing clarity and giving the sky a hazy appearance in many areas.

Despite the widespread unsettled weather, temperatures will stay high for the season. Western Macedonia will range from 7°C to 17°C, while the rest of Macedonia and Thrace will see 12°C to 20°C. Thessaly will range from 9°C to 20°C, Epirus and western Central Greece from 13°C to 20°C, and the rest of Central Greece from 12°C to 21°C. The Peloponnese will experience 7°C to 22°C, the Ionian Islands 17°C to 21°C, the northern and eastern Aegean islands 13°C to 20°C, the Cyclades 17°C to 20°C, the Dodecanese 16°C to 21°C and Crete 10°C to 21°C.

Winds across the seas will blow from the south at 4–6 Beaufort, affecting both the Aegean and Ionian waters and potentially influencing ferry schedules or maritime activities.

In Athens, expect mostly cloudy skies with a chance of brief, light local showers. Southerly winds will reach 2–4 Beaufort, and temperatures in the city center will range between 18°C and 20°C.

In Thessaloniki, cloud cover will dominate with the possibility of short-lived light showers. Winds will blow from easterly to southeasterly directions up to 3 Beaufort, with temperatures from 17°C to 20°C in the city center.
