Im no expert on the area but I would think that NW would be very off-shore at Aireys Inlet.
When I stay at my father in laws place at Jan Juc, I would usually sail 13th beach on a NW which is more or less side shore. The only problem is when it is big its really hard work and you need to be a good wave sailor to have any fun. Unfortunately, I am not a good wave sailor and last weekend I didn't even make it out the back and got smashed

.
Would be good to know if the are other options on the West Coast for NW wind.
