There is a KOA in Waves or Rodanthe (right across Highway 12 from Hatteras Island Surf and Sail and just north of the Real slider park). You can launch there and the SW wind is cleaner up that way. If you get all the way down to Buxton, where the original Real shop is, the SW is much gustier and you'll probably end up driving north to Avon anyhow. I'd angle for the KOA by Hatteras Island Surf and Sail.
