What the number means

Lake Superior: lake in the United States. 12 stations report water temperatures here, from Breakers Beach at 10.0 °C to Duluth at 14.5 °C.

The value comes from a thermometer in the water and is updated continuously; the measurement time is shown with every value. Compared with yesterday: minus 0.3 degrees.

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.
