Cannes has a Mediterranean climate, which means that Cannes is warm and sunny during the summer months and mild during the winter. Summertime highs average between 75 and 80 degrees Fahrenheit, with lows in the mid-60s. In the winter, highs average in the mid-50s and lows do not typically drop lower than 40 degrees. An ocean breeze keeps Cannes comfortable in the summer, while constant sun ensures a pleasant winter.
Summer is the peak of Cannes' tourist season, and July and August draw the biggest crowds. Highs in the low 80s and long, sun-filled days make this an ideal time for swimming and sunbathing. Yet, Cannes is an appealing destination during the other seasons as well. Sunny spring days feature temperatures in the high 60s and low 70s, making spring a prime time for sightseeing. Fall is similar, though there is more chance of rain and strong winds during this time of year. Cannes' mild winters are a good time to see the area's sights while also avoiding the typical summer crowds.
If you're visiting Cannes in the summer, you'll need your best beach clothes and lots of lightweight gear, as the days and nights will be very warm. During the spring and fall, you'll want to bring loose pieces for layering, especially during the cooler mornings and evenings, while the winter is best met with a sweater and a lightweight coat.
Cannes is situated on the Mediterranean Sea, making it an ideal spot for swimming. During the summer months, the water temperature averages between 75 and 85 degrees, with calm tides. You'll want to make sure you pack your swimsuit if you're planning to visit at this time of year.
Be sure to bring plenty of sunscreen to Cannes. Summer days in Cannes are long, with nearly 12 hours of sun, a perk that significantly increases your risk of getting a sunburn. Though winter days are shorter and too chilly for lying out on the beach, they are still sun-filled, so you'll want to be sure to pack your sunblock no matter what time of year you visit Cannes.
