*** 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.

Location & Local Information
Lyon, located at the confluence of the Rhône and Saône rivers in eastern France, is a vibrant city known for its rich history, culture, and cuisine. The Rhône River, which flows through the city, is an important feature of Lyon's landscape. While the river itself is known for its strong currents and rapid flow, it also offers several opportunities for outdoor activities, including swimming in certain areas. The water temperature of the Rhône River varies throughout the year, with summer being the most favorable time for swimming. During the warm months, particularly from June to September, the water temperature typically ranges from 18°C to 22°C (64°F to 72°F). While this temperature is refreshing, it is not as warm as some lakes, but it can still offer a pleasant swimming experience, especially during hot summer days.
Swimming in the Rhône River itself is not generally recommended in the central areas of Lyon due to the strong currents and busy urban environment. However, the riverbanks around the city offer plenty of recreational areas, such as beaches and swimming pools along the river's edge. The city also features designated swimming areas on the Saône River or public pools where locals and tourists can enjoy the water in a safer and more controlled environment. For those seeking outdoor water activities in Lyon, the Parc de la Tête d'Or, with its large lake, is a popular alternative, offering swimming during the summer months.
