weather conditions become less predictable.
Nevertheless, the absolute best day of diving I ever had off Morehead City was December 5, 2004. The temps at the surface were 80 degrees F, the seas were flat, and the vis was awesome. And that was diving with Leroy Crator off the "Captain's Lady".
You need to call the captains and see what they have to say. They're in the business of trying to please divers, and weather permitting they will do their best to get you out to the wrecks.
BTW - the trips are ~ 3 hours out and 3 hours back. You are some 60-70 miles offshore in the North Atlantic. Currents can be problematic. Use of jon lines is highly recommended. Ensure you can go down and come back up the anchor line - if you've never used Carolina rigging you should discuss with the Captain prior to dropping. Drink lots of water and consider using Triptone or Bonine if you've not been that far offshore previously. Ensure you have a SMB and reel, in case you get blown off the wreck. Boats are NOT live. You may drift for awhile...
It's the real deal.
dive safe,
