The summer heatwave is intensifying, with temperatures expected to reach 36°C tomorrow (22 June 2026), according to Greece’s National Meteorological Service (EMY). Strong winds—up to 7 on the Beaufort scale—will sweep across the Aegean Sea, while isolated thunderstorms are forecast for mountainous areas of Epirus and possibly Macedonia.
General Conditions
Overall, skies will be mostly clear. However, cloud development is expected during the afternoon and early evening across Macedonia, Epirus, and western Central Greece. Local showers are likely, especially over higher elevations. Isolated thunderstorms may occur in the mountains of Epirus and, less certainly, in parts of Macedonia.
By nightfall, conditions will improve nationwide—except in central Macedonia, where scattered light rain or showers are possible overnight.
