Weather in Greece: When temperatures are expected to plummet

Significant temperature fluctuations are expected across Greece in the coming days, with temperatures initially remaining above seasonal averages before dropping sharply on Sunday (November 15), particularly in northern parts of the country.

According to a social media post by Thodoris Kolydas, director of the Hellenic National Meteorological Service (EMY), and forecast data from the ICON-EU weather model, maximum temperatures on Thursday and Friday will range between 18°C and 24°C, with the highest readings expected in central and southern Greece. Minimum temperatures will generally range between 9°C and 19°C.

Relatively warm air masses will persist into Saturday, with daytime highs reaching between 17°C and 25°C across most regions.

According to Kolydas, temperatures in some isolated areas of southern Greece, including the Aegean islands and Crete, could locally reach as high as 27°C.

Weather Forecast for Thursday (November 12)

According to the EMY forecast, cloudy conditions with scattered showers are expected in the western and eastern Aegean. Elsewhere in Greece, skies will be partly cloudy, with cloud cover becoming denser in some mainland areas from the afternoon onwards.

Visibility will be locally reduced during the morning and evening hours, requiring extra caution when travelling.

Winds will blow from southerly directions at 4 to 6 on the Beaufort scale, locally reaching force 7 over the seas.

From the evening onwards, winds in the northern Aegean will shift to northerly directions, reaching up to force 8 on the Beaufort scale.

Where Temperatures Will Reach 25°C

Temperatures are not expected to change significantly on Thursday. Daytime highs will reach 20°C to 22°C in northern Greece, while the rest of the country will see maximum temperatures of 23°C to 25°C.

More specifically, according to EMY:

• Attica: 16°C to 24°C.

• Thessaloniki: 14°C to 22°C.

• Macedonia and Thrace: 8°C to 22°C, depending on the area.

• Epirus: 13°C to 19°C.

• Thessaly: 11°C to 25°C.

• Central Greece and Evia: 14°C to 24°C.

• Peloponnese: 15°C to 24°C, with regional variations.

• Cyclades: 17°C to 23°C.

• Crete: 14°C to 24°C.

• Eastern Aegean Islands: 15°C to 23°C.

• Dodecanese: 15°C to 23°C.

Weather Conditions to Change on Sunday

Weather conditions are expected to change significantly on Sunday, when temperatures will drop, particularly across northern Greece.

Specifically:

• Northern Greece: Maximum temperatures will not exceed 9°C to 13°C. Minimum temperatures will fall to between 5°C and 10°C, while in some mountainous and semi-mountainous areas, readings could drop as low as -1°C.

• Central Greece: Maximum temperatures will range between 13°C and 19°C.

• Western and Southern Greece: Temperatures will remain relatively higher, with daytime highs reaching 16°C to 22°C.

Referring specifically to the extreme values indicated by forecast models, such as 27°C in southern Greece and -1°C in the north, the EMY director clarified that these figures represent local maximum and minimum readings rather than temperatures expected across entire regions.

As he explained, the main temperature ranges provided by the models, covering the 10th to the 90th percentile, represent the typical temperature range for each area. However, the forecast also identifies individual locations where the greatest deviations from these ranges may occur.
