Sand Tiger Shark at the wreck of the Caribsea
Thanks be to God for a fine trip diving the wrecks with sand tiger sharks off North Carolinas coast, the Graveyard of the Atlantic, and to those who post good info. online to help people like me. This trip took a lot of research. I found several sources with some of what I needed to know, but none with everything. I struggled with how to write this trip report just a basic report vs. an introductory guide to the area based on my research, others online posts & my 5 days diving it? Whats the best way to help others have the good time I did, & decide if its the destination for them?
I decided on a hybrid approach. Ill open with what I cobbled together from other sources about the place and some of the issues involved in diving there. I'll hyperlink to the thread & give you a post # when I directly use someone else's content, for reference & citation (I originally paraphrased to give a smoother read, but switched to more quotes due to fear I'd be accused of plagiarism). Then Ill lay out my costs & arrangements for the trip, then discuss the trip. If you just want a trip report, cut to that and 'Bam!, youre done! I'll use pics a bit randomly to break up the text.

Wreck of the U-352
An Introductory Guide to some North Carolina Diving*

North Carolina.
North Carolina is a famous continental U.S. dive destination known for wreck diving with sand tiger sharks (link to a page on them). The state has an irregular/jagged coastline and offshore a long narrow barrier island chain forms a land wall running roughly parallel to the mainland, which has 2 sounds (inland waterways). Looking at a map, on that island string a bit under halfway down southward from the north border, is Cape Hatteras, a bend in Hatteras Island. Off the coast of N.C. is part of the region known as the Graveyard of the Atlantic, where several hundred+ ship wrecks occurred, some via U-Boats in World War II.
Down south a good deal and back on the mainland are Morehead City and Beaufort. Further down south, not all that far from the southern border, is Wilmington.

Atlantic City Beach, near Morehead City
The Labrador Current (cold) flows out of the north southward, and the Gulf Stream (warm) flows out of the south heading north. They collide roughly 2/3rd of the way up North Carolina, both turning to head out into the Atlantic. So south of that point, the same gulf stream that provides warm water and good+ viz. to Jupiter & West Palm Beach in Florida offers similar benefits to North Carolina divers south of Cape Hatteras. I think this is why you see fewer dive op.s & trip reports from Nags Head and plenty from Hatteras, Morehead City and Wilmington.
Packman (Post #15):
South of CapeHatteras, the majority of our offshore wrecks (20+ nm out) reside in the Gulf Stream. This gives us the same clear water (on average) and tropical critters as in Florida. When you move closer in to shore and out of the Gulf Stream, the average water clarity begins to drop. At Hatteras, the Gulf Stream turns out to sea and north of there, you are in the remnants of the Labrador Current. Here, you will generally find murkier and colder water.
That being said, it is the open ocean so the weather and water conditions are highly variable.
Steve_C (Post #9) noted:
For us the water gets warmer as you go out due to Gulf Stream in the winter. It is the reverse in the summer with the inshore warmer. The iffy part is the weather.
Unlike the tropics water temp.s are not constant; it gets cold in winter & spring (see When Boats Go Out, below).
Morehead City:
Pop. 8,661 in 2010 census. Steve_C (Post #9) noted:
The Morehead area has three parts split by bridges. There is Morehead with port and lots of seafood restaurants and charter boats, etc. There is Atlantic Beach which is a barrier island full of beach homes and a nice old fort and there is Beaufort. Beaufort is a historic little town on the intercoastal waterway. Waterfront looks onto an island with wild ponies. B and B s and good food. Sitting at a table on the waterfront, watching the sun set, a cold beer, and looking at wild ponies. Romantic Charm Central.
Type of Diving:


Mainly boat diving. North - wrecks. South - wrecks and ledges. Long rides out (e.g.: often 2 hour each way). For full day charters (2-tank, offshore) with Olympus Dive Center, arrive at 6 a.m., depart at 7 p.m., return ~ 3 - 4 p.m. A lot of the diving is deep & nitrox commonly used. The preferred diving is offshore - farther out with warmer water & better viz., but bad weather or other concerns can redirect you inshore, so bring exposure protection that can handle cooler water.
Steve_C (Post #4) noted:
Actually there are two kinds of diving out of NC. Wrecks and Ledges. Morehead is primarily wreck diving. Wilmington is a mix of wrecks and ledges. Aquatic Safaris does both for 8 months of the year.
Our shore and bottom is generally sand with a silt load close to shore. But we deepen slowly. It is only 100 ft deep 20 miles from shore. As this sandy bottom goes out every now and then it hits a rock ledge. The ledges can run for a mile or more and often have a drop of 10-20 ft. The ledge is usually undercut with lots of cracks and crevices. This is a major attractant for corals, sponges, and all sort of marine life. In other words they are like deep reefs. Going out from wilmington the first of the big ledges is 23 mile ledge. Top is around 85 and bottom around 100. A little further out is Sue's ledge at 26 miles. Top at 90 and bottom at say 105. Dove Sue's last week. Had well over 70 ft of viz. Loads of marine life. Gorgeous dive.

DA Aquamaster (Post #4) noted:
The Indra also sees a great deal of traffic from Olympus, as it's more or less their standard inshore dive when the waves get too large. As an inshore wreck it's labrador current diving and you'll want to plan on 65-70 degree water temps and 20ft visibility on the rough days when it's used as an alternate.
What I recall from my trip was offshore wrecks tended to be around 120 feet (give or take) to the sand, with the wreck structure atop that, but much of the main portion of the dive was roughly in the 90 - 110 foot range.
Lorenzoid of a July 2012 weekend trip (Post #11) noted:
Also, this was my first experience diving with a boat full of people who appeared much more prepared than your average tropical vacation diver. If I recall, everyone had at least a pony bottle, and some had doubles/sidemount, and one rebreather. I didn't see a single jacket-style BC. The crew gave a serious dive briefing--no joking around like I've seen in the Caribbean. Overall, a very interesting and motivational experience.
Note: In my 5 days diving, I saw a mix of BP/W & jacket BCDs, & ponies were in the minority (but present). The only doubles I recall were on one of the guides, but I didn't look for them. I agree it seems like a fairly seasoned customer base.

DVanKirk (Post #2) suggested a dive tourist start with Morehead/Beaufort as they offer the most wrecks with the highest amount of success, whereas Nags Head & Hatteras offer dives that can sometimes be a little harder to get to offshore due to weather & currents.

A good thread on considering an August 2013 Morehead trip.
When Boats Go Out:
This is the Atlantic Ocean, not the Caribbean, so sea conditions are not so predictably calm and a planned boat trip is subject to get blown out (cancelled due to bad weather). Waves may be larger than Caribbean divers are used to, making rougher boat rides & more difficult ladder exits from dives (neither was an issue on my trip). It is subject to seasonal risk of tropical storms and hurricanes. When possible, schedule enough dive days that one or two cancelled trips wont ruin your vacation.

Tortuga James (who runs Tortuga Charters, a 6-pack charter boat out of Morehead City) noted for people planning a trip well in advance, late May - August offer the best chances of nice weather; September & October tend to offer the best conditions underwater, but are riskier to plan in advance. He doesnt accept charters from Dec. - March 31st. Steve_C noted out of Wilmington boats run from early April to late October.
Seasonal Patterns:
Tortuga James input (Post #12):
Too many variables to predict on any given future day (and that goes for next week as well as next year).
But here are some common patterns.
March.... forget about it. Windiest month of the year.
April... Starting to get nice but water is still in the high 60's. Cold fronts still dominate the weather patterns. Usually one every 7-10 days. As the front approaches the wind howls SW for 24-36 hours the as it crosses the wind goes NW then NE for another 24-36 hours. Following the NE blow the wind shifts south and we have some nice days before the next one.
May- Cold fronts are coming with less frequency, but the same pattern exists but with longer stretches of warm nice days. Water temps are in the low 70's
June- Great month. Water has now reached mid 70's, days are long and the sun is bright. The cold fronts stop coming by the end of the month. Many long stretches of nice weather.
July- The hot air is here. Water temps climb to near 80. The Bermuda High dominates the weather pattern. A steady SW flow blows all month. Some days it is too windy to go out, but most days are just normal rough conditions. Visibility is usually excellent. Diving is great but the boating not so much.
August- The summer doldrums set in. Diving is great and we have many calm, hot days. The biggest weather threats are now tropical storms. By the end of the month we are watching the tropics for approaching hurricanes.
September- Hurricane season is in full force. They say that during the season the weather is great unless there is a hurricane. Very true. Great diving, warm (almost hot) water and generally some of the best visibility of the year unless a storm has just passed. Risky but you could have some of the best dives of your life if you get lucky.
October- Storm season is winding down and the cold fronts are starting. SW winds before the fronts are a little stronger than in the spring, but it is the same process. Nice weather follows after the front is well on its way. Tropical lows and hurricanes can still impact the weather. Still some of the best diving of the year if you catch it right. Water temps are still in the high 70's.
November- Cold fronts control the weather. Locals love this time of year. The water is still warm and the air can be too on a lot of days. Some of my best trips have been Thanksgiving weekend.
December- February- the diving can be good but the water is in the 60's and the air chilly, even on the best of days. Too risky to plan more than a day or 2 out. I don't even accept charters from December through March 31st.
There you have it. If I had to sum it up for those of you trying to plan well in advance, I would say late May through late June and August are your best chances of nice weather. July is good but bumpy. I think September through late October are the best conditions underwater, but a little risky to plan way ahead.
Having said all that, you could get the most perfect 4 day stretch or totally blown out in any month of the year. These are just general weather patterns for reference only. I make no warranties that what I have described is what you will experience when you get here. But get here, it is INCREDIBLE diving.
