The2007 European heat wave affected most ofSouthern Europe and theBalkans. The phenomenon began affecting Italy and Turkey on 17 June and expanded into Greece and the rest of the Balkans, Hungary and Ukraine on 18 June. The costs of the heat wave were estimated at 2 billion euros.[1]
Mainz, Germany recorded an average high of 22.4 °C (72.3 °F) for April, the strongest deviation (+6.2 °C (11.2 °F)) from the 1989-2018 average of any month. It was also the first calendar month without any measured precipitation since February 1959. A high of 29.4 °C (84.9 °F) was reached on 14 April.[2][3]
Up until 21 June, temperatures generally hovered around 36–39 °C (97–102 °F) in most of the aforementioned countries; however, starting on 22 June, temperatures skyrocketed in this entire region. From this point on,Greece,Italy,Albania,Bulgaria,Serbia,Croatia,Bosnia and Herzegovina,Romania andTurkey experienced record-breaking temperatures in a situation unprecedented even for these nations, typically used to conditions of extreme heat.
During the weekend of 23–24 June and on 25 June, temperatures soared to 43–44 °C (109–111 °F). By 26 June, however, Greece seemed to bear the brunt of the heatwave with temperatures inAthens reaching 46.2 °C (115.2 °F).[4][5] The same day, Greece's national power consumption set a new record.[6] Parts of Greece, including neighbourhoods in Athens, suffered from power outages due to high electricity demand and heat damage to the grid. Explosions from overheating transmission towers were implicated inthe forest fires ravaging the country.[5] The discomfort was exacerbated by high night-time temperatures, which exceeded averages by up to 8 °C (14 °F), and remained at very high levels for more than half of the 2007 summer.[4]
More than 200 people were hospitalized for heat-related treatment and 18 people died fromheat exhaustion. By 28 June northerly winds started blowing from the northwest and temperatures finally began falling, reaching a cooler 39 °C (102 °F). Nonetheless, at a time when everyone believed that the worst part was over, more than 100 fires erupted across the country. Two people perished in the village of Aghia, near the city ofLarissa. In the evening of that same day a majorwildfire broke out inMount Parnitha near Athens. By the dawn of 29 June, a significant part of the popular Parnitha National Park had turned into ashes. Temperatures fell by as much as 6 °C (11 °F) and the worst heatwave since records began came to an end leaving Greece reeling upon its disastrous effects.
By late July, temperatures again rose to more than 40 °C (104 °F) in Southern Europe, impacting agriculture, electricity supply, forestry and human health. From 21 to 25 July, temperatures reached or exceeded 45 °C (113 °F). Over 500 deaths inHungary were attributed to the heatwave.[7] Major wildfires destroyed large forested areas across the region. Six people (including twoCanadair pilots) lost their lives while trying to extinguish the flames in Greece. The country's electricity grid nearly collapsed due to exceptional demand for air conditioning. Hundreds of tourists were stranded on the beaches ofApulia, in Southeastern Italy, and had to be rescued by boats.[8]
In Bulgaria, six people were killed in the fires that started on 22 July. An estimated 1,530 fires broke out between 20 and 24 July, three times the yearly average. During the largest fire nearStara Zagora, 50 square kilometres (19 square miles) of pine forest burned for three days, as firefighters were unable to control the fire by conventional means. Strong winds and the extremely dry air quickly sparked new fires. The government requested help from Russia, andBe-200 amphibiouswater bombers finally managed to contain the blaze near Stara Zagora.[9][10]
