Cremorne lagoon is the hot place to be , on a good se seabreeze youget about 15 people out. Cifton beach also good if you want surf, river if you want... well the river
Park/Carlton Beach can be good if it's a true SE, in theory it should be cross-on however most south easterlies tend to more SSE. Marion Bay (boneyard) has been known to produce good wavesailing conditions in strong SE winds.
