Why Are These Cities So Hot Right Now?
Southern Europe is currently under a strong heat dome — a high-pressure system trapping hot air from North Africa. Combined with the urban heat island effect in dense cities like Rome and Madrid, temperatures easily climb above 40°C in the afternoon.
The European Heatwave Trend
Over the past decade, Europe has experienced increasingly frequent and intense heatwaves. According to the Copernicus Climate Change Service, 2023-2026 have been among the hottest years on record for the continent. Spanish cities like Seville and Cordoba regularly top 45°C during peak summer.
Health Risks During Extreme Heat
- Heat exhaustion — headache, dizziness, nausea
- Heat stroke — body temperature above 40°C, life-threatening
- Dehydration — drink 2-3 liters of water daily during heatwaves
- Sleep disruption — indoor temperatures above 28°C harm sleep quality
- Cardiovascular stress — especially dangerous for elderly and children
