Meteorologists forecast another hot southern European summer in 2026. Spain, Italy, Greece, and southern France regularly exceed 38°C in July and August — plan sightseeing for before 10:00 and after 18:00, and treat midday as pool, museum, or siesta time. Air-conditioning is not universal in older European apartments; verify AC before booking Airbnb in historic centres.
Cooler alternatives shine in peak heat. Portugal's Atlantic coast, northern Spain (Galicia, Cantabria), the Balkans, and Scandinavia offer beach weather without inland furnace temperatures. Dublin, Edinburgh, and Bergen provide city culture with milder thermometers — and summer fares that stay reasonable when Mediterranean routes sell out.
Hydration and sun protection are non-negotiable — reusable water bottles, SPF 50, and hats save hospital trips. Train travel beats hot airport tarmac waits on corridors like Milan–Nice or Barcelona–Marseille when flights delay in heat-related operational slowdowns.
