Despite the fact that the beach season opens at the end of May, not everyone risks entering the water at this time. After winter, it slowly gains temperature. In March-April the Mediterranean Sea warms up to +14-16°C, in the last month of spring - up to +18°C. Full-fledged bathing season begins closer to mid-June, when the water temperature in Nice reaches +21°C. In July-September the water is warm - +24-25°C. Comfortable for bathing water temperature in Nice remains until mid-October.
Tides in the Mediterranean Sea are insignificant, but waves in the Bay of Angels can sometimes suddenly cover part of the beach. However, this happens infrequently and very rarely in summer.
