That's about this:
"Weather conditions are usually benign during the summer, although the north and west coasts of the island are not good places to be if a mistral blows up, as there is a long fetch all the way from the coast of France. Seabreezes are mostly light along the coast, with the exception of the Strait of Bonifacio, where yachts will often encounter winds 2 or 3 Beaufort more than the prevailing breeze. A bracing 4/5 SE will often be experienced as a near-gale 6/7 as you near the Straits."
There are plenty of protected anchorages and marinas. I was talking about a passage to continental France with a fixed date. that could be a bad idea because that piece of sea is the one more exposed to the Mistral.
