Heatwave hits southern Europe: Temperatures above 40°C spark wildfire risk; experts issue warnings

Southern Europe is battling one of its most intense heat waves in the recent years, with temperatures crossing 40°C in countries including Italy, Spain, Greece, and Portugal. Authorities have issued fresh health warnings and raised the alarm over potential wildfires, as scorching conditions continue to grip the region.

According to experts, climate change is driving both the frequency and severity of such heatwaves, with southern Europe emerging as the hotspot for extreme weather events.

Italy, Greece, Spain, and Portugal witnessed severe heat conditions over the weekend, forcing locals and tourists to take shelter during the day. In Portugal, nearly two-thirds of the country remained on high alert on Sunday, with Lisbon expected to hit 42°C. Fire and emergency services were also on standby in case of wildfires.

In Italy, authorities in regions like Lazio, Tuscany, Calabria, Puglia, and Umbria are planning to restrict outdoor labour during peak heat hours. Meanwhile, trade unions have urged the central government to roll out such protections nationwide. On Sunday, Italy's Health Ministry placed 21 of its 27 monitored cities, including popular tourist destinations Rome, Milan, and Naples, under the highest-level heat alert.

In Rome, tourists were seen crowding shaded spots near the Colosseum and Trevi Fountain, armed with umbrellas and water bottles. Similar scenes played out in Milan and Naples, where street vendors reported a surge in demand for lemonades and cold beverages.

A major wildfire erupted south of Athens last Thursday, reigniting Greece’s wildfire concerns amid the ongoing heatwave. Fueled by strong winds, the blaze forced evacuations and road closures near the iconic Temple of Poseidon. Over 130 firefighters, supported by 12 aircraft and helicopters, were deployed to control the fire. Authorities evacuated more than 40 people from five affected areas as smoke blanketed the region and flames threatened nearby homes.

Meanwhile, Spain sweltered under oppressive heat, especially in the southern city of Seville, where temperatures reached 42°C. Health advisories were issued as multiple southern and central regions reported above-average seasonal temperatures. Spain’s national weather agency AEMET has warned that this June could be the hottest since official record-keeping began.

Public health officials across the region advised residents to stay indoors during peak afternoon hours, remain hydrated, and avoid physical exertion. Vulnerable populations - especially children, the elderly, and those with pre existing conditions - are at risk the most.

A 2023 Lancet Public Health study underscored the growing danger of climate-linked heatwaves. It warned that without drastic policy shifts, heat-related deaths in Europe could quadruple by mid-century. While more deaths currently occur due to cold, the report said the benefits of milder winters will be outweighed by the rising toll of extreme heat.
