The travel year in Schlesien, 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 | 19 | 9 | 0 °C |
| February | 37 | 13 | 3 °C |
| March | 11 | 27 | 6 °C |
| April | 16 | 49 | 11 °C |
| May | 28 | 67 | 16 °C |
| June | 51 | 76 | 21 °C |
| July | 81 | 73 | 22 °C |
| August | 97 | 76 | 22 °C |
| September | 54 | 71 | 17 °C |
| October | 36 | 51 | 12 °C |
| November | 22 | 25 | 6 °C |
| December | 20 | 12 | 2 °C |
The crowd level is season-relative: 100 is the annual peak of Schlesien 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.
