If your planning on staying the Hatteras area contact their Avon office. Fishing in July can be pretty exciting. The weak fish and drum are pretty much back in the sound by this time of year and the channels behind Avon can yield some excellent catches. You can also find spanish mackeral, bluefish, croaker, and flounder in the sounds. Surfside you'll find pretty much the same assortment with a few small jack tossed in for good measure.
Offshore fishing is some of the best in the world.
Marlin, sailfish, dolphin, king mackeral, wahoo and yellowfin tuna are all common catches.
