The travel year in Karlsruhe, 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 | 5 | 18 | 4 °C |
| February | 18 | 23 | 5 °C |
| March | 31 | 35 | 8 °C |
| April | 52 | 53 | 12 °C |
| May | 66 | 67 | 16 °C |
| June | 73 | 77 | 21 °C |
| July | 86 | 74 | 22 °C |
| August | 87 | 75 | 22 °C |
| September | 77 | 70 | 18 °C |
| October | 70 | 57 | 13 °C |
| November | 43 | 31 | 7 °C |
| December | 34 | 20 | 5 °C |
The crowd level is season-relative: 100 is the annual peak of Karlsruhe 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.
