we can thank the obx for that one. they always block the swell from the south and the eastern shore blocks the swell from the north. basically, were in of the worst spots on the east coast. due to the lack of significant swell, our sandbars are also sh1t most of the time
they messed up the north end when they ran the storm drain pipes 1/2 mile out. the break at 79th st was sweet. it would break when a fish farted. use to have 3 line ups. now the beach is big and goes out to the outside break.
About the time the sandbars start to work the replenishment begins again. You'll have to chase the sand around until it begins to settle in one place and hopefully in a decent wave producing form. Seems like there is usually somewhere down there that has a little more sand than the rest of the spots. Luckily/unluckily there's a lot of parking so checking all 5 miles of the beach isn't the pain it once was.
Also, unlike the oceanfront areas, there isn't much structure to slow down the sideshore current. By the time a north-to-south current reaches SB it's trucking right along and all that incompatible sand migrates south to the refuge and false cape where the unreplenished beaches use it as god/allah/buddah/neptune/poseidon/santa intended.
