Heat will persist across Greece tomorrow, Sunday, August 30, 2026, with temperatures exceeding 35°C in many areas. A dense, oppressive atmosphere is expected due to the transport of Saharan dust — a phenomenon that reduces air quality and visibility, especially in western regions.
Saharan Dust and Rising Temperatures
According to the Hellenic National Meteorological Service (EMY), atmospheric conditions favor the inflow of African dust over western Greece. Temperatures are forecast to rise slightly in southeastern parts of the country, reaching 34–36°C across the Ionian Islands and mainland western regions — locally hitting 37°C. In the Aegean islands, thermometers will climb to 31–32°C, while the Dodecanese and southern Crete may see highs of 34–35°C.
Wind Conditions
Winds will be variable at 3–4 Beaufort in western Greece. Across eastern mainland areas, northerly winds of 4–5 Beaufort are expected, strengthening to 6 Beaufort in the Aegean Sea — and reaching up to 7 Beaufort temporarily in the southeastern Aegean, including parts of the Dodecanese and southern Crete.
Localized Showers and Thunderstorms
Isolated cloud cover is expected in northeastern Greece during early morning hours, while afternoon and evening cloud development is likely across most inland regions. This will trigger localized showers or isolated thunderstorms — particularly over mountainous areas of Macedonia, Epirus, and western Central Greece.
Regional Breakdown
