The crowd level is season-relative: 100 is the annual peak of Oeste e Vale do Tejo itself, not the busiest destination in Europe. The figures say when it is quiet here — not where it is quieter than elsewhere.
Weather comfort 0–100 from the climate normals, profile “mild” – the same profile as the recommendation above, not the selection in the calendar. A “–” means the data for that month is missing.
