*** 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 Béthune River, located in northern France, flows through the Hauts-de-France region and joins the Lys River. This small river is primarily known for its scenic landscape, featuring green meadows and quiet villages. Water temperatures in the Béthune are typically cool, ranging from about 10°C to 18°C (50°F to 64°F), influenced by the regional climate and seasonal changes. Summers see the warmest temperatures, although the water remains fresh and brisk due to limited sun exposure and the river’s modest depth.
Swimming in the Béthune is not common due to its temperature and smaller size, as well as its primary use for irrigation and fishing. However, it offers picturesque spots along the banks that are ideal for picnicking, walking, or observing local wildlife. For those interested in water activities, kayaking or canoeing on the nearby Lys River or other larger waterways may offer a more suitable and enjoyable experience.
