hi woody46, i'm around narrabeen area,
For NE Narrabeen lake at the western end
Balmoral, Kyeemagh (botany bay), Palm beach can be ok at the lighthouse end, it is offshore though
SE Bilarong reserve @ narrabeen lake, clontarf, Sandy point (palm beach)
West Bilarong reserve, foreshore drive @ botany (other side of the runway), palm beach (comes over the back & can be gusty)
Nw palm beach lighthouse end, comes in from lion island,
SW palm beach golf course end
South sandy point @ palm beach, possibly clontarf
Kyeemagh works in most directions other than west. I've also sailed in manly harbour a few times, comes through in south or north east (offshore) - watch out for the ferries though, the passengers laugh when you get catapulted

I'm sure a few of the other guys here will have some more suggestions for you
Hope those nor-easters come through, todays fizzled out by the time i got to Balmoral
