The travel year in Kassel, 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 | 12 | 2 °C |
| February | 15 | 16 | 4 °C |
| March | 21 | 26 | 6 °C |
| April | 43 | 44 | 10 °C |
| May | 68 | 65 | 15 °C |
| June | 76 | 76 | 19 °C |
| July | 85 | 76 | 20 °C |
| August | 87 | 77 | 20 °C |
| September | 70 | 71 | 17 °C |
| October | 57 | 49 | 11 °C |
| November | 28 | 26 | 6 °C |
| December | 17 | 15 | 3 °C |
The crowd level is season-relative: 100 is the annual peak of Kassel 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.
