Greece is now experiencing the heatwave that has swept across Europe. On Tuesday, 30 June 2026 — and continuing into Wednesday — temperatures are expected to reach up to 39°C in several inland areas. However, unlike more extreme episodes elsewhere in Europe, this heatwave is not forecast to bring record-breaking or dangerous conditions. Instead, the coming days will feature a mix of high temperatures and increasing atmospheric instability, with scattered thunderstorms and showers expected across multiple regions.
Today and Tomorrow: Hot, But With Localized Storms
Tuesday will see generally clear skies over most of the country, though afternoon and early evening cloud development is likely over mainland areas. Isolated showers and thunderstorms are expected — particularly in Epirus, western and central Macedonia, and the mountainous zones of western Central Greece and western Peloponnese.
Winds will blow from northerly directions at 3–5 Beaufort across the country, reaching up to 6 Beaufort locally in the Aegean Sea.
Temperatures will range between 30°C and 32°C in the northern Aegean and Cyclades, 34°C to 36°C elsewhere, and locally up to 37°C in inland areas.
Wednesday, 1 July
Clear skies will dominate again, with brief cloud cover developing over the mainland during the afternoon and evening. Light rain and isolated thunderstorms are possible in northwestern Greece. Winds remain northerly at 3–5 Beaufort, peaking at 6 Beaufort in parts of the Aegean. Temperatures hold steady: 30°C–33°C in the Cyclades and northern Crete; 34°C–36°C elsewhere; and up to 37°C inland.
Thursday, 2 July
Another mostly sunny day, with afternoon cloud build-up over mainland regions. Localized rain and isolated thunderstorms are expected — especially over central and northern mountainous areas. Winds shift slightly to northwesterly (3–5 Beaufort), reaching 6 Beaufort locally in the southeast. No significant temperature changes are anticipated.
Friday, 3 July
Cloud cover increases in northern Greece, especially in the afternoon and evening, bringing isolated showers and thunderstorms. Elsewhere, skies remain largely clear, though brief clouds may form inland during midday and afternoon hours — occasionally producing light rain or isolated storms in mountainous zones. Winds stay northwesterly (3–5 Beaufort), with local gusts up to 6 Beaufort in the southeast. A slight cooling trend begins in northern areas.
Saturday, 4 July
The forecast for Saturday is cut off in the original text, but earlier trends suggest continued warm, mostly clear conditions in the eastern and southern island regions — with potential for localized afternoon instability continuing through the weekend.
