Here is my read for what it's worth... Looking at Windguru today and this far out, I personally say Sat closed (the island has a relatively new harbor captain or whatever they are called) and Sun maybe open. However, you are still a ways out and things can change. If the current prediction generally holds it will then depend on what time the wind shifts late PM Sat/early AM Sun from coming from the N/NE to coming from the E that will allow time for the waves to settle on the west side of the island. Winds can blow like crazy out of the east but that leaves the west side of the island where the diving is at almost a dead calm. Winds out of the east from Monday on look great all week but, unfortunately, like all of us, we have to depart sometime.
Try not to fixate on this even though everyone (including myself) does. Your trip is booked and you'll be diving when you can and when you can't you'll find other things to do.
