How Grand Bay NERR, Mississippi Sound fishes
Open water lies to the south of Grand Bay NERR, Mississippi Sound. A wind out of the south is onshore here — it stacks swell and chop into the mouth and pushes stirred-up water inshore, while a north wind flattens the surface and tends to clean it up.
This is an inshore station — bay, river or lagoon water rather than an open ocean mouth. Tide stage and water temperature drive the bite here far more than swell does.
Tides here are read from NOAA station 8740166 at 30.4132, -88.4029 — see it on NOAA CO-OPS.
