Sunny weather will prevail across most of Greece today, with temperatures rising slightly in many areas, particularly across the Ionian Sea and the mainland. However, conditions will not remain completely stable, as temporary cloud development is expected during the afternoon over inland regions, with localized showers affecting the northern mountains. Isolated thunderstorms are also possible early this morning in Epirus and Western Macedonia.

Winds will strengthen significantly over eastern Greece and the Aegean Sea, reaching 7 to 8 Beaufort in some areas, creating more challenging conditions for sea travel. Winds will remain lighter in western Greece, while strong northerly to northeasterly winds will continue along southern coastal areas.

Temperatures will range between 33°C and 35°C across most mainland regions, reaching 36°C locally in western Greece. The Cyclades and Crete will see highs of 29°C to 32°C, while the Ionian Islands and the Dodecanese will reach up to 33°C.
