Climate data: Open-Meteo ERA5 historical archive, the five most recent complete years (2021–2025). Scores are monthly averages for that window, not forecasts, and short-window precipitation can differ from longer-term normals. “Sunny days” count days with at least 6 hours of measured sunshine — they are not dry days.
