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
Réservoir de Grosbois, located in the Jura department in the Bourgogne-Franche-Comté region of France, is a tranquil and scenic artificial lake primarily used for water retention and fishing. While it is not a heavily developed tourist destination for swimming, it does offer opportunities for outdoor activities, including fishing and kayaking. The water temperature in the lake can vary significantly throughout the year, with the highest temperatures typically reached during the summer months of July and August. During this period, the water temperature can range from 20°C to 22°C (68°F to 72°F), providing a pleasant environment for swimming, although it may not be as warm as other more famous lakes in the region. Swimming is more popular in the summer, but it is advisable to check the water quality regularly since there are no designated swimming areas or lifeguards at the lake.
In the colder months, especially in the spring and fall, the water temperature drops considerably, often falling to around 10°C to 14°C (50°F to 57°F). These lower temperatures can make swimming uncomfortable, and swimmers should be cautious about potential cold-water shock. While the lake’s calm, clear waters make it an ideal spot for fishing, kayaking, and boating, those wishing to swim should take precautions due to the lack of formal swimming facilities. The surrounding area also offers several hiking and biking trails for those who enjoy exploring nature. In summary, while swimming in Réservoir de Grosbois is possible, it is more of a serene spot for relaxation and water activities rather than a designated swimming destination.
