Water warmer on the Roanoke than at the coast

Stripers continue to fire off in the river, the water is still a little cool at the coast but it's going to warm up quick.   I made a bluestery stroll out there yesterday and never found anything warmer than 64.   We did catch some sea bass, a 26 inch drum in 90 ft of water on a sting silver, a really nice American Red and an oversized bluefish.     Saw no cobia, but it's going to happen very, very soon.
