Friday, 26 June 2026, will bring mostly clear skies across Greece, according to the National Observatory of Athens (EMY). Sunny conditions are expected in most parts of the country, though scattered clouds will develop over western and northern mainland regions during the afternoon. Local showers or thunderstorms are possible in those areas — particularly over mountainous terrain, where isolated thunderstorms cannot be ruled out.
Wind and Temperature Outlook
Northerly winds will dominate the weather pattern. In the Ionian Sea, winds will blow at 3–5 Beaufort, while in eastern mainland areas and the Aegean, they’ll reach 4–6 Beaufort. Locally — especially in parts of the Aegean — gusts may hit 7 Beaufort.
Temperatures will rise slightly, peaking at 33–35°C in inland areas and staying between 30–33°C on the islands — maintaining typical summer conditions nationwide.
