Chris, the bluegill typically bite well at that time. Slab crappie is also possible then too. If your boat is set up to spider rig then early and late produce pretty well.
persoanlly I like to catfish during the summer too. Especially after a rain, or even on a rainy day with not alot of wind. Ditches and mouths of ditches do well after a good rain. Although we can go long periods here with not alot of rainfall.
Anyway, good luck whatever you do.
