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
Bayonne is a charming city located in the Basque region of southwestern France, at the confluence of the Adour and Nive rivers. The Adour River plays a significant role in the local economy and recreational life. It is known for its steady flow and scenic beauty, attracting visitors for activities such as boating, fishing, and walking along its banks. Swimming in the Adour River is generally not recommended for the public in most parts of the city due to strong currents and fluctuating water levels. However, during the summer months, when the water temperature can range from 18°C to 22°C (64°F to 72°F), swimming is occasionally possible in designated, monitored areas, such as specific beaches or river spots.
The city itself has several municipal swimming pools, which are the safer and more popular options for residents and tourists looking to enjoy swimming during the summer. Additionally, the proximity of Bayonne to the Atlantic Ocean means that many people prefer to swim at the nearby beaches, such as those in Anglet or Biarritz, where the conditions are much more suitable for a swim. While the Adour River offers an ideal setting for other water activities, swimming is typically limited to regulated locations to ensure safety.
