Measured, with trend
What the number means
Alster: lake in Germany. One official station reports the water temperature here: Alster, operated by Badegewässer Hamburg (BUE/BUKEA).
The value comes from official bathing-water monitoring: samples every two to four weeks in season, most recently on 14 Oct. Between two samples the water can move by several degrees, up on hot days, down after thunderstorms.
Below 15 degrees the body answers with the cold-shock reflex: an involuntary gasp, racing pulse. Enter slowly, breathe out calmly, never swim alone. The app gives a per-sport verdict and warns when your favourite water drops below your own threshold.
