During the morning hours, cloud cover with showers and localized thunderstorms will develop over Macedonia, Thessaly, and possibly the Sporades islands. As the day progresses, similar conditions are expected to extend to other mainland areas, particularly over higher terrain.

Storms in Epirus and Macedonia may be intense, featuring frequent lightning and local hail. Conditions will begin to improve from the afternoon onward, though showers and thunderstorms may return in the evening over western Central Greece and the central Ionian Sea.

In contrast, much of southern Greece, the Aegean islands, and Crete will experience sunshine with just a few scattered clouds. Visibility may be locally reduced during the night and early morning hours.

Temperatures:

  • Northern Greece: 19°C to 36°C (Western Macedonia: 14°C to 27°C)
  • Central & Southern Mainland: 21°C to 35°C
  • Western Greece: 18°C to 31°C
  • Cyclades & Crete: 22°C to 33°C
  • Eastern Aegean Islands: 20°C to 36°C
  • Dodecanese: 24°C to 31°C

Winds:

  • North and Central Aegean: Light to moderate northerly winds (3–5 Beaufort)
  • South Aegean: Westerly winds, also 3–5 Beaufort
  • Ionian Sea: Light to nearly moderate northwesterly winds (3–4 Beaufort), reaching up to 5 Beaufort in the northern Ionian at times

Regional Forecasts:

  • Athens:
    Expect mostly sunny weather with some clouds, increasing in the afternoon, especially in northern and mountainous parts of the region. There’s a chance of a brief local shower or thunderstorm. Temperatures will range from 24°C to 35°C, slightly cooler (by 2–3°C) in the northern and eastern suburbs. Winds will be light and variable, turning locally northerly in the east up to nearly moderate strength (4 Beaufort).

Traveler’s Note:

If you’re visiting northern or mountainous parts of Greece, be prepared for possible rain and storms, particularly around midday. Southern regions and islands are expected to remain mostly dry and sunny, making them ideal for outdoor activities and beach outings. Keep an eye on local forecasts if traveling in Epirus, Macedonia, or Thessaly, as weather could briefly become intense. Visibility may be reduced overnight, so caution is advised for early morning driving.
