The travel year in Länsi-Suomi, 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 | 4 | 2 | -6 °C |
| February | 19 | 3 | -5 °C |

| October | 23 | 24 | 5 °C |
| November | 16 | 10 | 1 °C |
| December | 10 | 4 | -3 °C |
The crowd level is season-relative: 100 is the annual peak of Länsi-Suomi 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.
