Greece braces for unstable weather, thunderstorms and rain across the country

A series of forecasts for June 10‑12, 2026 predicts that Greece will experience continued heat with temperatures around 31‑35 °C, interspersed with periods of instability. Strong meltemi breezes of 5‑6 Beaufort are expected in the Aegean, while isolated hail and thunderstorms are likely in mountainous areas of Macedonia, Epirus, the Pindus range and the Peloponnese.

On Friday, June 12, a cold atmospheric disturbance moving from the Balkans will increase instability nationwide. The system is expected to bring cooler air, stronger winds and widespread rain and thunderstorms, especially in northern and central regions such as Macedonia, Thrace and Thessaly, with additional showers forecast for Attica and the northern Aegean. Temperatures are projected to dip slightly after the front passes.

Overall, the weather outlook calls for heightened vigilance for fire risk during the hotter periods and for potential flooding or wind damage during the upcoming stormy episodes.
