Italian weather forecasts are very unreliable and the wind
on that region and on that month are pretty irregular, going from very weak winds to F8 occasionally.
Even if the weather reports are unreliable it is easy to stay out of F8, you just have to give a discount of about 2 Beaufort
force regarding the weather report and you will be out of trouble.
You will find very uncomfortable to sail upwind with more than F5. Count with a lot of motoring hours (unless you have a boat
that can sail in very weak winds) and take the time you need to stay out of trouble (you can divide the voyage in smaller legs if bad weather is on the way).
Have fun and enjoy the ride
