Localized showers and thunderstorms are expected primarily across mainland Greece, including the central and northern regions. Some of these storms may be accompanied by strong winds and small hail, particularly in central and northern areas. During the evening, rain and isolated thunderstorms are also forecast for parts of the northern Aegean. In contrast, fair weather is anticipated for the southern Aegean islands, the Ionian Sea, and much of western and southern mainland Greece.

Temperatures:

  • Western Macedonia: 14°C to 27°C
  • Rest of Macedonia & Thrace: 15°C to 33–35°C
  • Thessaly: 15°C to 32°C
  • Epirus: 13°C to 32°C
  • Western Greece: 14°C to 33°C
  • Other mainland areas: 14°C to 34°C
  • Ionian Islands: 19°C to 30°C
  • Aegean Islands & Crete: 18°C to 31–33°C

This marks a modest cooling trend across the mainland, especially in areas affected by cloud cover and storms.

Winds:

Winds will generally blow from northwesterly directions across both the Aegean and Ionian Seas, ranging between 4 and 5 Beaufort, with occasional gusts reaching up to 6 Beaufort, especially in open waters.

Regional Highlights:

  • Athens and Attica:
    The region will see partly cloudy skies with local showers and possible thunderstorms during the warmer parts of the day. Winds will be light, predominantly northwesterly at 2–3 Beaufort, and may briefly reach 4–5 Beaufort in eastern parts of the prefecture. Temperatures will range from 26°C to 33–34°C.

Travel & Activity Tips:

Travelers in northern and central mainland Greece should be prepared for sudden weather changes, especially in the afternoon. Outdoor plans may be briefly disrupted by rain or storms. Visitors to the islands, particularly in the south, will continue to enjoy more stable, summer-like conditions. If you plan to travel by sea, be aware of moderate wind conditions that could slightly affect ferry schedules or onboard comfort.
