About these numbers
Averages of every day from 2023 to 2025 in the global atmospheric composition model of the Copernicus Atmosphere Monitoring Service, served by the Open-Meteo Air Quality API (CC BY 4.0), for the city center, in local time. They describe a typical day, not any one day: the UV on a given day can be higher or lower, so check the forecast before you go. Solara is a planning aid, not medical advice.
