Greece braces for Saturday storms before Sunday sun returns
Heavy rain and thunderstorms are forecast to sweep through eastern and northern Greece on Saturday, with a return to mostly sunny skies and a temperature rise expected on Sunday.
Saturday's unsettled weather
A bout of severe weather is set to grip parts of Greece on Saturday 13 June 2026. Forecasts from the Hellenic National Meteorological Service (EMY) point to heavy rain and thunderstorms, particularly across the eastern mainland, the Sporades islands, Evia, and the northern Aegean islands. The unsettled spell began on Friday, when downpours turned streets into rivers in areas of Attica like Acharnes and Ano Liosia, and hail struck parts of Larissa and Lamia.
- Severe storms in Chalkidiki and eastern Macedonia during the early hours.
- Heavy rain and thunderstorms continue in Thrace, NE Aegean (Limnos area), and Evia.
- Storms ease in the Sporades and Evia; local showers develop over central Macedonia and Peloponnese mountains.
- Weather improves from the west; scattered clouds and isolated rain over Crete.
- Mostly sunny nationwide with few afternoon clouds, rising temperatures.
Regions under warning
EMY has highlighted specific areas where the phenomena will be most intense. In Chalkidiki and eastern Macedonia, storms are expected during the early hours. The Sporades and Evia will see strong storms until the pre-noon period, while Thrace and the northeastern Aegean islands, especially around Limnos, are forecast to experience heavy rain through the morning. On the eastern mainland, in Evia, the Sporades, and the northern Aegean, clouds will bring rain and scattered thunderstorms, some locally strong. Crete's mountains may also see thunderstorms in the morning, with conditions gradually improving.
Winds and temperature trends
North winds of 4 to 6 Beaufort will prevail, reaching 7 Beaufort locally at sea. These winds will contribute to a slight temperature drop on Saturday, especially in the east. Maximum values will range from 25 to 28°C across most of the country, with the west and south locally reaching 29 to 30°C. In Attica, temperatures will peak at 27°C; in Thessaloniki, also 27°C. Northern Greece will see 17 to 27°C, with western Macedonia 2 to 3 degrees lower. Crete will stay between 17 and 26°C, and the Dodecanese around 21 to 27°C.
Sunday's improvement
Conditions will markedly improve on Sunday 14 June. After the stormy Saturday, most of the country will enjoy generally clear skies, with only a few temporary clouds developing during the midday and afternoon hours, mainly in the Peloponnese, eastern Macedonia, and Thrace. There is a possibility of local showers in mountainous areas of those regions. However, the overall picture is one of a return to summery weather.
