A score above 80 indicates excellent conditions for sightseeing, outdoor activities, and photography. Scores between 60–80 mean good but imperfect weather. Below 60, consider indoor alternatives or rescheduling. The forecast is updated daily with data from Open-Meteo and is most accurate within the next 1–3 days.
