Greece weather: High temperatures up to 38°C with cooling trend expected
Greece is experiencing high temperatures and sunny conditions as of early September 2026. Many regions are seeing temperatures reach up to 38 degrees Celsius, with heatwave warnings issued for areas including Crete, the Northeast Aegean, the Dodecanese, and the Ionian Islands.
While the current weather remains summer-like with strong northern winds in the Aegean, meteorological forecasts indicate a gradual transition. A decline in temperatures is expected to begin around September 8, with more significant cooling and potential atmospheric instability, including local rain and thunderstorms, predicted for the western and northern parts of the country between September 12 and 15.
Long-term seasonal outlooks from the ECMWF suggest a potentially milder winter for Greece with lower than average snowfall, though individual cold spells remain possible.
