Generally fair weather is expected across most of Greece on Friday. However, scattered showers and thunderstorms are likely during the afternoon and early evening, especially in the mainland mountain regions. Temperatures will be unseasonably high, particularly in central and northern areas.

General Conditions

  • Morning to early afternoon: Mostly sunny with occasional local cloud cover.
  • Afternoon to early evening: Thunderstorms and showers may develop, mainly in the mountains of northern and central Greece, with occasional spillover into nearby lowlands.
  • Intensity: Storms in mountainous areas may be locally intense.

Temperature Highlights

  • Western Macedonia: 13°C to 29°C
  • Eastern Macedonia & Thrace: 16°C to 33–35°C
  • Thessaly: 16°C to 34–36°C
  • Western Greece: 17°C to 31–32°C
  • Rest of mainland: 18°C to 34–36°C
  • Ionian Islands: 16°C to 31–32°C
  • Aegean Islands & Crete: 17°C to 31–33°C
  • Eastern Aegean Islands: Peaks of 35–36°C

These values suggest hot daytime conditions, so light clothing, hydration, and sun protection are recommended for outdoor activities.

Wind Conditions

  • Aegean Sea: Northwest winds at 4–5 Beaufort (moderate to fresh breeze).
    • Southern Aegean: Winds shift to westerlies, same strength.
  • Ionian Sea: Westerly to northwesterly winds at 3–4 Beaufort.
  • Gulf of Corinth: Westerly winds, 3–5 Beaufort, may be noticeable in coastal areas.

Note: Beaufort scale 3–5 means breezes strong enough to rustle leaves or create whitecaps at sea—generally safe for travel, but small craft should take standard precautions.
