Just stumbled across this handy page. I've been using the BOM site for years but never came across this before. So for those few of us that don't have a local Seabreeze forecast here's the next best thing.
There used to be a similar chart available commercially from the BOM I once had access to on a minesite I was working at. I'm not on that site any more, but it gave some interesting long term wind forecasts. Of course, the accuracy of them was only as good as the public ones anyway, so +7 days out wasn't often much use anyway.
