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
Istres is a town located in the Bouches-du-Rhône department, situated along the Étang de Berre, a large saltwater lagoon near the Mediterranean coast. This lagoon, which covers about 155 square kilometers, has warm water temperatures, especially during the summer months. In the peak of summer, the water temperature of the Étang de Berre can reach up to 22°C to 26°C (72°F to 79°F), making it quite comfortable for swimming. The mild Mediterranean climate contributes to a long swimming season, from late spring to early autumn.
Although the Étang de Berre is a popular spot for water activities such as sailing and kayaking, the water quality can be variable depending on industrial activity around the lagoon. Local authorities closely monitor the water, and there are designated swimming areas to ensure safety and cleanliness. However, swimming in some parts of the Étang de Berre might not be ideal due to potential pollution from nearby factories. Visitors should check local guidelines and recommendations before swimming to ensure a safe experience. For those looking for cleaner and more controlled swimming environments, there are nearby beaches along the Mediterranean coast, offering excellent conditions for swimming.
