when fishing shallow shoals(or a hump that comes up very shallow) when is the best time to fish these early morning? what to throw? any suggestions

Any time of day. In low light, topwater and suspending jerkbaits might work, shallow running crankbaits over the top and deep running lures around the edges. Soft plastics would be my choice the majority of the time, especially Senko, Fat Ika, lizards, Kut-Tail, GYCB 8 1/2" worms and Micromunch Tackle El Gordo tubes.

These shallow humps may also be more effective after 3 steady days of wind upon them.   It positions blown plankton upon the humps which shad will feed upon, thus positioning the bass also.
