Water Temperature: Daily Trends, Historical Records, and Forecast
❌ As of today, the minimum water temperature ranges less than 41°F (5°C). Such water is extremely cold and not recommended for swimming without proper preparation. In these conditions, the risk of hypothermia is very high, and prolonged exposure to the water can be hazardous to your health. If you decide to swim, it is important to have the appropriate gear, such as a wetsuit. Typically, only experienced swimmers or those who practice winter swimming venture into such waters. It is important to note that these swimming tips and recommendations apply only in good weather. When the air temperature is below 68°F (20°C), and sometimes even below 77°F (25°C), swimming can be unpleasant even with relatively high water temperatures.

*** 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.

The Alzette River, flowing through Luxembourg and parts of France, is a smaller river known more for its scenic charm and historical landmarks than for swimming. Due to its relatively mild current and narrow course, its water temperature generally varies with the season, reaching around 15°C to 20°C (59°F to 68°F) in the warmer months. In winter, the temperature can drop significantly, often falling below 5°C (41°F). This fluctuation, along with the river's modest depth and occasional pollution issues, makes it less popular for swimming compared to larger rivers in the region.
There are no official swimming areas along the Alzette, partly due to water quality concerns in urban areas like Luxembourg City. However, people often enjoy walking, cycling, and picnicking along its banks, particularly in scenic areas where the river passes through lush landscapes and historic sites. Although swimming is not recommended, the Alzette offers a pleasant environment for recreational activities close to nature.
