I doubt you'll need a shortboard in these months, though maybe you'll get the odd hurricane swell.

Camping:

Carolina Beach/Kure Beach has a campground near Fort Fisher. Good surf no one around, as good as WB.

Masonboro Island: Know about it? It's wilderness, a preserve. Just find a captain to drop you off. You could stay there for weeks as long as you duck the coastguard. good peaks on the north end.

OBX: The lighthouse has public campgrounds, so does Oregon Inlet. If you're coming up the coast there's a ferry from Ocracoke. The lighthouse is essential surf/travel experience.

There might be a few other barrier islands on the coast that are preserves as well and offer good surf.
