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
Mont-de-Marsan is located at the confluence of the Midou and Douze rivers, which together form the Midouze River, running through the Landes region in southwestern France. The water temperature in the Midouze River varies seasonally, typically remaining between 8°C and 12°C (46-54°F) in the winter and rising to around 18°C to 22°C (64-72°F) during the summer months. The relatively mild water temperatures in the warmer months make it possible to enjoy recreational activities near the river, although swimming is not widely practiced directly in the Midouze due to safety and water quality concerns.
Swimming in the Midouze around Mont-de-Marsan is generally discouraged, as there are no designated swimming areas in the immediate river. Instead, the focus is on maintaining the river’s natural habitat, which supports a variety of fish and other wildlife. For swimming options, residents and visitors often head to nearby lakes and swimming pools, where water quality and safety are better monitored. There are also some recreational sites along the river where visitors can enjoy scenic views, picnicking, and hiking along the riverbanks.
