Greece braces for 48 hours of extreme heat stress as temperatures soar above 40°C
Very high to extreme heat stress is expected today and tomorrow in many areas of Greece due to the strong heat wave that prevails in the country. According to the latest forecast data from and the Athens National Observatory, heatwave conditions will persist in the country on Thursday 24 July, with the mercury rising to 40-42 °C and locally 43 °C in many areas. On Friday 25 July, a slight further rise in temperature is expected with the mercury reaching or exceeding 44 °C locally. High temperatures, combined with the duration of the heatwave, are contributing to the increased risk of heat stress in most of the country. More specifically, according to the HEAT-ALARM biomechanical warning system and as indicated on relevant maps, Thursday 24 July is expected to bring very high heat stress in most parts of the country. Extreme heat stress in Thessaly, the northern mainland and the East Aegean islands.

The 'most critical period' for wildfire conditions At the same time, from today, Greece is entering "the most critical period of deterioration of pyrometeorological conditions" in almost all of the country, according to the FLAME pyrometeorological team of the METEO Unit of the National Observatory of Athens. In particular, they say "the cumulative effect of the very hot and dry conditions prevailing in our country already from Sunday 20 July 2025 has led to a significant increase in the flammability of forest fuels, making it very easy for fires to start, large heat loads to develop, fire to spread rapidly and spotting to occur".

"From today until Saturday 26 July 2025, north/northeast (N/NE) winds are expected to strengthen in the eastern mainland and the Aegean Sea, which will lead to a significant strengthening of the potential for wind-driven fires (especially on Friday 25 and Saturday 26 July 2025). The above leads to a significant and potentially dangerous escalation of fire weather risk, so the difficulty of controlling any incidents that may occur will be very high and locally extreme," the FLAME team underlines.

Greece considers water-saving moves as heatwave intensifies
Greece has announced plans to "urgently" overhaul its water management as temperatures continued to rise during a week-long heatwave. Prime Minister Kyriakos Mitsotakis said the cabinet had discussed plans to make water companies more "viable", noting that reserves in Athens were down 50% compared to three years ago. There will be additional use of desalination technology and water reuse, the premier's office said, adding that Greece globally ranked 19th in terms of drought risk. The National Observatory of Athens recently warned that, following high temperatures and low rainfall in June, almost all of Greece displayed above-normal drought levels for this time of year. Temperatures continued to rise in a heatwave expected to last until Sunday. Between 40C and 44C are expected in the eastern, central, and northern inland regions, as well as on the islands of the eastern Aegean Sea, according to the website of the Athens National Observatory. In Athens, the heat reached 36.3C around 1.30pm (11.30am Irish time). It is expected to rise to 42C tomorrow according to To protect visitors and guards, Greek authorities have closed the Acropolis in Athens during the hottest hours of the day, between 1pm and 6pm, until Friday. The Greek government has also banned outdoor work in several sectors during the hottest hours to minimise health risks. "It's inhumane to work in such conditions. The asphalt is boiling," Panagiotis Arvanitidis, a member of the food delivery workers' union in the Thessaloniki region (north), said. "The ambient temperature in my home over the past two days has exceeded 30C," said another Athens resident. "Without air conditioning, survival is impossible!" she added. The heatwave's highest temperatures so far were recorded on Tuesday at Tragana, central Greece, at 44.9C, according to A Mediterranean country accustomed to intense summer heatwaves, Greece last year experienced its hottest summer on record.
