*** Forecast - Our water temperature forecast
Actual nearshore water temperatures may fluctuate by several degrees from the reported values, especially following heavy rainfall or extended periods of strong winds. Certain wind patterns can cause colder, deeper waters to rise and replace the sun-warmed surface water, leading to noticeable variations.
Our forecast is based on a proprietary mathematical model that considers real-time water temperature changes, historical trends, key weather patterns, wind strength and direction, and air temperature specific to each region. Additionally, we incorporate data from other resorts to enhance accuracy.

Location & Local Information
Located in the Lower Saxony region of Germany, Hannover is a charming city nestled along the banks of the Ihme River - a small but vital waterbody that significantly contributes to the city's scenic landscape. The Ihme River, mainly a tributary of the Leine River, twists its course through the urbanized areas, providing for a surprising touch of natural beauty in the midst of the city.
As for the water temperature in the Ihme River, it varies with the seasons as with any naturally occurring water body. Typically, the temperature tends to be cooler in the winter months, often dropping to near freezing, while in the summer, it can warm up quite considerably, reaching up to around 20 degrees Celsius (68 degrees Fahrenheit) or slightly more depending on the weather conditions.
Where swimming in the Ihme River is concerned, it's technically possible but not always recommended. While some locals may engage in the activity during hotter months, it should be noted that the river isn't formally designated for swimming. There is no official infrastructure for bathing like life guards, marked swimming areas, or water quality checks. In addition, the water quality can be variable, particularly following rains, with possible discharges from stormwater drains. Visitors and locals are often advised to use the public swimming pools around the city for the safest swimming experiences.
