The sea is often warm enough for swimming, particularly in late spring and early autumn.For those looking to enjoy the beaches and the bustling energy of the French Riviera, July and August offer the warmest weather and the liveliest atmosphere. However, this is also peak season, so you should expect more visitors, higher prices, and busier beaches.If you're interested in hiking and exploring the region's natural beauty, the cooler months of April or late October can be ideal.
