21.62026, provisional

2026: 21.6 hot days up to the cut-off date – 2.0 times the decade average. This puts Wuppertal above its previous record year 1994 (18.5 days). The count covers the first 292 days of the year, up to 19 October. The year is therefore not yet complete, and the figure comes from the daily grid rather than the annual grid, which the DWD only publishes after the end of the year. Over the three most recent years available in both, the two agree on average (+0.18 days); for a single city they typically differ by 1.5 days, in individual cases by up to 6.8. This figure is not included in any decade average or any rank on this page.

Context

This figure describes the location of Wuppertal. No city administration decides on location. On shade over streets, schoolyards and playgrounds, it does.

What can be changed

Location is fixed, the residential surroundings are not

38.6 %of the residential surroundings is tree cover
Rank 32of 80 for green where people live

This measures the share of residential surroundings covered by trees – from the satellite, weighted by the population of the same 100 m cells as the heat figure above. Both figures therefore apply to the same places and can stand side by side. Parks, cemeteries and gardens count. The city’s stock of street trees requires the tree register.

Examples in the same location

Cities with a similar number of hot days and a similar size to Wuppertal that have clearly more green where people live:

  1. Wuppertal10.6 days38.6 %
  2. Bochum11.6 days49.9 %
  3. Mülheim an der Ruhr10.9 days49.1 %
  4. Essen10.7 days47.9 %

Hot days per year, average 2016–2025, and green where people live. Compared are cities no more than 1.5 hot days apart, at most three times as large or as small, with at least 5.0 percentage points more green. Green also depends on urban form and topography; the comparison shows what occurs in the same location and is not a grade for any administration.
