Well, I ended up at Quibray Bay (all alone until a kite turned up towards the end).
Really good spot in a SW!
The swell was max 20cm at the beach (down wind) and dropped to < 5cm when I went upwind a bit.
The surrounding mangrove trees are about 2-3m high, so not to bad at blocking the wind.
Just not as good as a sandbar.
Quibray is probably better than George's river at HIGH TIDE! much smoother, with nice little sandie patches on the Eastern edge near the mangroves to stand in while you adjust the outhaul.
It might even be better than the George's River sandbar, as the swell should be more consistent, rather than peaking just before you start the run downwind. I'll have to see in a SE.
