Greece weather: Summer heat persists before autumn transition
Greece is experiencing a period of warm, summer-like weather through the weekend, with temperatures in many regions reaching between 30 and 33 degrees Celsius. Most of the country will see sunny skies, though some local rainfall or showers are expected in the mountainous areas of Epirus, Western Macedonia, Thessaly, and Central Greece during the afternoons.
Forecasts indicate a significant shift toward autumn starting early next week. A transition to cooler conditions is expected from Tuesday, with a more pronounced drop in temperature and increased instability predicted for the latter half of the month. Specifically, between September 26 and 29, a low-pressure system in the Ionian region may bring heavier rains and storms, particularly to western Greece.
Wind conditions remain variable, with stronger northerly winds expected in the Aegean, potentially reaching 6 Beaufort in some areas. Desert dust transport continues to affect the Dodecanese, though in low concentrations.
