Heatwave Hits Across Greece: Temperatures to Soar Near 40°C

The heatwave is upon us, with temperatures expected to rise significantly across the country. As summer kicks off, thermometers are gradually climbing but reaching alarming levels, signaling that within the next few days, they may approach 40°C. While today’s temperatures are forecasted to reach up to 33°C, and the weather remains generally clear nationwide, the situation is set to change from the coming days. By Friday, temperatures are projected to increase by 4-6 degrees above the current highs of 33-35°C, nearing the 40°C mark. The most concerning aspect is that this intense heat will affect every region in Greece. Weather forecasts indicate extremely high temperatures for Thursday in Lemnos, Lesbos, and Agios Efstratios. Today’s (June 3, 2025) general forecast predicts mostly clear skies with some localized cloud formations during midday and afternoon hours over mountainous mainland areas, where isolated showers are possible. Winds will be westerly-northwesterly at speeds of 3-5 Beaufort and locally up to 6 Beaufort in southeastern regions. Temperatures will slightly rise, reaching 27-29°C in the islands and 30-32°C in mainland areas, with local peaks hitting 33°C Celsius. Specific regional forecasts include Attica, Thessaloniki, Macedonia-Thrace, Ionian Islands-Epirus-Western Sterea, Western Peloponnese, Eastern Sterea-Euboea-Eastern Peloponnese, Cyclades-Crete, Eastern Aegean-Dodecanese, Thessaly, and more detailed predictions extending through Saturday, June 7, 2025. These forecasts warn of further minor temperature increases leading to abnormally high levels for this time of year.
