The travel year in Graubünden, month by month
The year as a table to read and to cite: crowd level for every month, plus weather comfort and temperature from the climate normals.
| Month | Crowd level0–100, season-relative | Weather comfort0–100, profile “mild” | Avg temperature |
|---|---|---|---|
| January | 63 | 3 | -4 °C |
| February | 95 | 5 | -2 °C |
| March | 60 | 8 | 1 °C |
| April | 18 | 17 | 5 °C |
| May | 18 | 28 | 9 °C |
| June | 43 | 44 | 14 °C |
| July | 81 | 43 | 15 °C |
| August | 79 | 44 | 15 °C |
| September | 47 | 37 | 11 °C |
| October | 34 | 25 | 7 °C |
| November | 5 | 10 | 1 °C |
| December | 43 | 4 | -3 °C |
The crowd level is season-relative: 100 is the annual peak of Graubünden 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.
