*** 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 Loire River, the longest in France, flows from the Massif Central to the Atlantic, covering a wide range of landscapes and climates, which influence its water temperature. During summer, the Loire’s water can reach around 20°C to 25°C (68°F to 77°F), making it comfortable for swimming in certain areas. However, in winter, temperatures drop significantly, often to 5°C to 10°C (41°F to 50°F), which is less suitable for swimming. Due to the river’s variable currents and occasional strong flows, caution is advised for swimming, especially in unmonitored areas.
Swimming is allowed in designated parts of the Loire, particularly near river beaches and calmer tributaries where currents are gentler. Popular swimming spots along the Loire include areas around Saumur and Montsoreau, which are scenic and monitored in peak summer months. Many people also enjoy kayaking, canoeing, and other water activities along the river, particularly in areas with châteaux that add historical charm to the landscape.
