What the number means
Horstmarer See: lake in Germany. One official station reports the water temperature here: Horstmarer See – Mitte Badezone, operated by Badegewässer NRW (LANUK).
The value comes from official bathing-water monitoring: samples every two to four weeks in season, most recently on 12 Aug. Between two samples the water can move by several degrees, up on hot days, down after thunderstorms.
Outside the bathing season there are no new samples; until the season starts again in spring, this page shows the last sample of the season.
The app shows the same stations with full history, BrrScore per sport and an alert when the water reaches a temperature you set.
