The Eider River, the longest river in Schleswig-Holstein, Germany, offers varied water temperatures depending on the season and location. During the summer months, the water temperature can range between 16–22°C, with warmer spots often found in slower-flowing sections or areas exposed to prolonged sunlight. In winter, temperatures drop significantly, reflecting the cold climate of northern Germany.

Swimming in the Eider is possible, particularly in designated recreational areas. While certain stretches near reservoirs or calm bends are suitable for swimming, the river's tidal influences closer to the North Sea and its sometimes strong currents make swimming less advisable in other areas. Always check for local advice and designated safe swimming zones to ensure a safe and enjoyable experience.
