0 of 47 major European cities are on a red heat-health alert today (Tuesday, 22 September 2026); Seville tops the Mobi Doctor Climate Health Index at 8.6/10.
7 European cities face a tropical night tonight — nights above 20°C block the body’s recovery from daytime heat.
In 6 of Europe's major cities, today's temperatures exceed safe carrying conditions for insulin, Ozempic/Wegovy and adrenaline auto-injectors — inside a parked car they are compromised within 30 minutes.
Turin is Europe's pollen capital today: mugwort pollen scores 7.0/10 — a severe allergy day despite a daytime high of only 26°C.

Each city's Climate Health Score (0–10) is the worst of ten hazard pillars — heat, cold, UV, air pollution, pollen, allergy, hydration demand, mosquito activity, fire weather and flu — plus a compound-risk bonus when several are elevated at once. The heat pillar combines feels-like maximums, tropical nights, humidity, UV, ozone, heatwave persistence and the city's share of residents aged 65+. Weather, UV, air-quality and pollen inputs are live (Open-Meteo/CAMS); mosquito, fire-weather and flu indices are modelled and labelled as such. Full methodology on the interactive map.
