France : climate and when to go to Lacanau
Saint Tropez , Marseille, Nice, Cannes and all the other cities of Mediterranean front sports a summer sungenerous of 81°F in the shade on average but which can climb to 95°F punctually. The sea is generally at 77°F but the winds of mistral or tramontana (towards Perpignan) cool the sea and sometimes it drops to 70°F, a pity because it does not rise very quickly afterwards.
On the side of Aquitaine, Lacanau , Biarritz, the temperatures are milder and the naturally cool ocean can bring on the beaches , water at 73°F in its best days, but it is often 70°F in summer. Moreover, the sun is less present in general than on the Gulf of Lion.
If you prefer the Channel or Brittany, I say good luck, even in summer!

Weather uncertainties 2025 to go to Lacanau ?
When traveling in the tropics as a seaside, rain is not welcome. If you see this indicator, with possible storms, that does not mean that it will rain all day long. When we observe the local rainfall, it is either really zero or very weak. Meteorologists prefer to be pessimistic. So observe below, the skies photographed during a week announced stormy in Asia. It did not rain once. I invite you to integrate this parameter before going to Lacanau for a good trip to the sun!
