The verdict

Shelling. Decent shelling. Low water 0.5 ft at 4:00 PM off Lighthouse Beach — walk the bars 2:30 PM – 5:30 PM.

Fishing. Fair fishing. 9:35 AM – 12:35 PM, 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.
