The good sailing is all in the northern half of the bay. The south end of the bay is shallow, somewhat weedy, and has some small boats moored there. Boat traffic is virtually non-existent. The best winds are from the south or southwest off the ocean. The local geography seems to cause a venturi, cranking a 15-knot breeze up to 25 or so.
Westerly winds are offshore from the launch site, but fairly sailable.
Northwesterlies are cross-offshore on port tack. The bottom is sandy. The bay is heated by the sun, and hence quite salty. It's shallow enough that you can stand in most places, especially if the tide's out. There is very little chop in the bay.
