On the evening of 15 July, the main railway station in Reggio Emilia, a city in northern Italy’s Po plain, stood under water. Commuters waded through ankle-deep floods as lightning flickered over the tracks. The station was one of hundreds of sites overwhelmed in a matter of hours when a powerful storm system, born of days of exceptional heat, tore across Emilia-Romagna.

The human cost was immediate. In Bomporto, near Modena, a 68-year-old man died when his car collided with another on a road lashed by rain and wind. Witnesses described near-zero visibility at the moment of impact. Across the region, firefighters logged over 1,000 call-outs, from fallen trees that crushed parked cars to roofs ripped off houses in Poviglio and Brescello, forcing families to evacuate. The storm’s fury was not isolated: it was the violent hinge between a continent-wide heatwave and a sudden plunge into autumnal chill.

For days, Europe had baked. In Sweden, temperatures climbed to 32°C, with a peak of nearly 34°C in some eastern areas, prompting warnings for heat-stressed railways and ‘bleeding’ asphalt. Spain’s interior braced for 40°C, while France’s south-east awaited the mistral that would, perversely, push the mercury even higher. But meteorologists from Stockholm to Bologna had been tracking a low-pressure system building over the North Sea and northern Germany. By the weekend, it would slash temperatures by half: southern Sweden was forecast to drop from 30°C to 10°C, and the Emilia-Romagna plain, still reeling from the storm, would see the thermometer fall below 30°C after one more day of red-alert heat.

The abrupt shift triggered a cultural reflex. Swedish tour operators reported a 25 per cent surge in last-minute bookings the moment the cool, rainy forecast solidified. ‘It goes like a train,’ said the CEO of one travel firm, as sun-deprived Swedes snapped up packages to Turkey, Crete, and Rhodes. In France, the orange alert for 26 departments on 17 July – with warnings of hail, 130 km/h gusts, and intense rainfall – was met with a collective exhale after several stifling days, as French forecasters noted. The relief was palpable, even if the storms brought their own dangers.

By week’s end, the continent was split. In Bologna, parks remained closed so crews could clear fallen trees and check the stability of those still standing. In the Languedoc, the mistral compressed and heated the air, pushing temperatures to 37°C while the north shivered. The image of a flooded station in Reggio Emilia, water reflecting the station lights, lingered as a reminder that Europe’s summer of 2026 was not a steady simmer but a series of violent swings, each one leaving its own debris.
