In 2023, Europe has been affected by heat waves. The most significant of these so far has been the ongoing named heat wave, Cerberus Heatwave, which is expected to bring the hottest temperatures ever recorded in Europe. Starting on 10 July 2023, the record-breaking Cerberus anticyclone affected many European countries, with the effects felt most severely in parts of Southeast and Southwest Europe such as Cyprus, Greece, Italy, and Spain. The Italian Meteorological Society named the extreme weather event after the hound of Hades from Greek mythology. It is one of the first major named heatwaves in history; temperatures were predicted to exceed 48 °C (118 °F) and break the record for the hottest ever recorded in Europe. The European Space Agency predicted temperatures in Italy exceeding 50 °C (122 °F). The event also led to record-breaking high temperatures in the Arctic following a week of the hottest global average temperatures ever recorded. Several regional temperature records have also been broken, and the heatwave has prompted health warnings and government action in several countries.
According to the British Met Office, 2023 is expected to have more intense heatwaves than those experienced in 2022.[1] In June, the European Environment Agency warned that schools and hospitals were at risk of high temperatures.[2]

In late June and mid-July, the combination of daytime temperatures of 35 to 40 °C (95 to 104 °F) and high humidity led to formation of a series of uncommonly strong, supercell storms in the area ranging from Slovenia to Romania.[70] On 23 June, large hail destroyed crops in parts of Slovenia and Hrvatsko Zagorje. In Croatia, the storm also broke windows in Varaždin and tore roofs off several houses in Međimurje.[71][72] On 13 July, one such storm travelled 1,100 km (680 mi), producing hail throughout its distance with stones up to 14 centimetres (5.5 in) in diametre in Krško, Slovenia, and a wind speed in excess of 100 km/h (62 mph; 28 m/s) in Zrenjanin, Serbia.[73]
On 19 July, a particularly strong supercell caused extreme wind damage in Slovenia and northern Croatia. Six people were killed:[74] four in Croatia (two in Zagreb, one in Cernik, Brod-Posavina County, and an on-duty firefighter in the Vukovar-Srijem County),[75] one near Lake Bled, Slovenia, and one in Brčko, Bosnia and Herzegovina. Many more were injured, including at least 60 in Zagreb, 10 of them severely. The storm caused extensive wind damage and electricity outages in parts of Slovenia, northern Croatia and northern Serbia.
