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
Luxembourg City is known for its unique position atop cliffs overlooking the Alzette River, which winds its way through the capital’s picturesque valleys. While the Alzette adds natural beauty to the city, its water temperature remains relatively cool throughout the year. During the summer, water temperatures in the Alzette typically range between 14°C and 18°C (57°F to 64°F), keeping the river fresh but not especially comfortable for swimming. As the Alzette flows through urban and industrial areas, water quality can sometimes vary, which further limits its suitability for swimming.
In Luxembourg City, swimming in the Alzette is generally not recommended. The river’s depth and flow rate can vary widely, and it is not maintained for recreational swimming. However, the river’s scenic banks are perfect for walking, cycling, and enjoying the city’s natural environment. For those who wish to swim, Luxembourg City offers numerous public pools, and several recreational lakes with monitored swimming areas are accessible within a short drive, offering safer and more comfortable swimming conditions.
