The travel year in Aostatal, 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 | 49 | 4 | -4 °C |
| February | 58 | 6 | -1 °C |
| March | 42 | 9 | 0 °C |
| April | 16 | 16 | 4 °C |
| May | 3 | 28 | 8 °C |
| June | 25 | 47 | 14 °C |
| July | 80 | 62 | 17 °C |
| August | 93 | 61 | 16 °C |
| September | 20 | 47 | 12 °C |
| October | 3 | 31 | 8 °C |
| November | 2 | 11 | 1 °C |
| December | 42 | 5 | -3 °C |
The crowd level is season-relative: 100 is the annual peak of Aostatal 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.
