Tuesday will bring mostly clear and sunny weather across Greece, making it an excellent day for outdoor plans, sightseeing, or travel. However, during the afternoon hours, localized showers and thunderstorms may develop in the mountainous mainland areas due to daytime heating.

Temperatures

A slight drop in maximum temperatures is expected in some regions, though the weather will still be hot by seasonal standards:

  • Western Macedonia: 14°C to 29–30°C
  • Eastern Macedonia & Thrace: 14°C to 34–36°C
  • Thessaly: 15°C to 34°C
  • Epirus: 13°C to 34–36°C
  • Other mainland areas: 15°C to 35–36°C
  • Ionian Islands (e.g., Corfu, Kefalonia): 18°C to 33–35°C
  • Aegean Islands & Crete: 18°C to 33–34°C
  • Rhodian & Southern Cretan regions: Highs up to 36–38°C

Travel Tip: Those visiting Rhodes or southern Crete should prepare for intense heat during the afternoon—plan beach visits early or stay hydrated and indoors during peak heat hours (1–4 PM).

Wind Conditions

  • Aegean Sea: Northerly winds, generally strong, ranging from 5–6 Beaufort, with occasional gusts reaching 7 Beaufort (strong breeze to near-gale).
