Outer Banks may be the most consistent area on the east coast... But in summer, everywhere is susceptible to the flat spells. From what I know, Corolla doesn't generally pick up swells like the areas to the south.
I'm looking out the window at Frisco Pier and the surrounding area right now. Looks like it's gonna be a great day if it cleans up. Few days ago was firing too. Next couple should be alright - stay around the pier, avoid the inexperienced longboarders, and have some fun.
