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
Dinan, located in the Brittany region of France, is a charming medieval town situated along the Rance River. This river, which flows into the English Channel, is popular for activities like sailing, kayaking, and fishing. While the Rance River offers picturesque views and is an excellent spot for various water sports, swimming is not as commonly practiced in the river itself. The water temperature in the Rance River varies throughout the year, and it can be quite cool, especially during the colder months. In winter and early spring, the water temperature tends to stay between 8°C and 12°C (46°F to 54°F), making swimming uncomfortable and even risky.
In the warmer months, particularly from June to September, the water temperature in the Rance River rises to a more comfortable range, typically between 14°C and 18°C (57°F to 64°F). This can create more favorable conditions for swimming, although strong currents and tidal movements in certain parts of the river may still present challenges for swimmers. For those seeking a safer and more controlled swimming experience, Dinan is close to several beaches and swimming areas along the coast of Brittany, where water temperatures are warmer and conditions are better suited for a swim. While the Rance River offers beautiful scenery, it is important to assess the conditions before swimming.
