Sunshine Atlas: monthly sunshine scores and climate normals for 3,833 airport-served destinations

Monthly 0–100 Sunshine Scores, average day/night temperatures, rainfall and sea-surface temperature for 3,833 destinations worldwide — every destination served by its own airport (one primary airport per metro area). Derived from long-term climate normals, not forecasts, by Sunshine Atlas. Files: sunshine-atlas-destinations.csv — one row per destination (identity, coordinates, elevation, population, climate band, destination type, annual sunshine hours, rainy days, best month, year + 12 monthly Sunshine Scores); sunshine-atlas-monthly-climate.csv — one row per destination-month (45,996 rows: score, day high °C, night low °C, rain mm, sea temperature °C); sunshine-atlas-destinations.json — both combined, with per-destination page URLs. Join key: iata. The Sunshine Score combines daytime warmth (ideal 20–32 °C), dryness and annual sunshine hours into one 0–100 number per destination-month: methodology.
