The verdict

Shelling. Decent shelling. Low water 0.6 ft at 2:34 PM off Lighthouse Beach — walk the bars 1:04 PM – 4:04 PM.

Fishing. Fair fishing. 8:25 AM – 11:25 AM, outgoing water.

Shelling grades the lowest daylight low water. Fishing looks for moving water inside a calculated solunar period, in daylight. Both are rules of thumb, not promises.
