Today (22 July 2026), Greece enters the most intense phase of an ongoing heatwave that has gripped the country for several days. Temperatures are expected to soar as high as 43°C locally, accompanied by winds reaching up to 6 on the Beaufort scale. This volatile combination has pushed the fire danger level to Category 5 — the highest — across three regions: Attica, Central Greece, and the Peloponnese.
Record Heat Driven by the Libas Wind
According to meteo.gr, the hot, dry Libas wind is set to intensify today. Originating from southwestern air masses, it accelerates down the eastern slopes of the Pindus Mountains, warming further as it descends. This phenomenon drastically lowers humidity, worsens heat stress, and dramatically increases both the likelihood and speed of wildfire spread.
Where Temperatures Will Peak
The Hellenic National Meteorological Service (EMY) forecasts the highest temperatures today in:
- Thessaly: up to 43°C;
- Eastern Central Greece and eastern Peloponnese: up to 42°C;
- Attica: 40–41°C.
In addition to these areas under extreme fire risk (red alert), six more regions are under orange-level fire warnings: the wider Peloponnese, Western Greece, Central Greece, Thessaly, Central Macedonia, and the South Aegean.
Storms and Safety Measures in the North
Late this afternoon and into the evening, colder air masses moving in from the northern Balkans will trigger strong atmospheric instability over northern Greece. Severe thunderstorms are expected mainly in Macedonia and Thrace, potentially bringing frequent lightning, heavy downbursts, large hail, and gusty winds exceeding 100 km/h in places.
Due to the hazardous conditions, access to and presence on Lycabettus Hill and Sheikh Sou in Athens have been officially prohibited today.
Relief Expected Soon
A gradual cooldown is forecast starting Friday, with temperatures dropping by as much as 10°C and scattered showers arriving across parts of the country.
