On Tuesday, October 27, high tide at Grand Bay NERR, Mississippi Sound is at 10:40 PM (2.0 ft); low tide is at 7:51 AM (-0.3 ft) (CDT, heights above MLLW). The table above lists the next 7 days.
The highest predicted tide in the next 12 months is 2.3 ft on December 23, 2026 at 8:36 PM. The largest tides fall a day or two after a full or new moon, especially when the Moon is closest to Earth.
Yes — on 171 days in the next 12 months the low tide drops below 0 ft (MLLW). The lowest is -0.7 ft on December 23, 2026 at 6:34 AM. Minus tides expose the most shoreline, which is why tide-poolers look for them.
Station local time (CDT at the time this page was built), with daylight saving time applied where the area observes it — the same convention as NOAA's own tide tables.
From NOAA CO-OPS, the U.S. government tide station network (tidesandcurrents.noaa.gov); the predictions are public domain. The curve between highs and lows is our interpolation. This page is not for navigation.
