Callala can be fun In southerly. Launch at boat ramp go upwind to the reef and dw back again or if it's big ride the waves on the reef . Works sw to se with good fetch across the bay

Look up Dave/Dr Surf here or online. He is part of a group who foils from Huskisson and also Swan Lake. They also have an active WhatsApp group.
I'll be out at Culburra this morning. Launch from the most northerly point of the beach at the car park near the holiday park. Good spot in the NE.
Second what siny said about Culburra in all southerly wind.

There's a friendly crew of foilers who launch from the north end of Collingwood Beach, just south of Moona Creek in Vincentia.
This spot has good wind, good access and you can cover the whole Bay from here if you like.

The swell is variable in the bay depending on the direction, but the north east wind chop out in the bay can be good from this location as there's a long fetch for it to build some size in a decent wind.

I've seen Anyboard, just about, very nearly, almost paddle into a long downwinder on his downwind SUP
And I've also seen Anyboard, trailing the wing most of the way, just ride the wind chop from out of sight upwind to just about out of sight downwind.
Yeah, Jervis Bay is nice.

What's the wind strength in average over there ?
