There's always a chance Gerroa will work, though this time of year the seabreezes, if it comes through, tend to be short lived blowing for a couple of hours then dying off mid to late afternoon. There isn't enough difference between the sea and the land temp to get the real seabreeze thing happening is my understanding of it. Having said that the last few late season N/ne have been rippers. Light winds but with fun swells pushing in from the south.
If the wind stays North it will be too offshore for fun sailing at Gerroa
