Where Cat Island is
Cat Island sits at 30.2317° N, 89.1167° W on the northern Gulf of Mexico, about 7 mi south of Long Beach, MS. The station here is a subordinate tide prediction point. NOAA has no gauge in the water at this spot; its times and heights are published as offsets from a reference gauge, named below. The closest gauge measuring live water level is St. Louis Bay entrance (NOAA 8747437), 14.1 mi away, and high and low water here run on average about 47 min earlier than there. The nearest weather station is Gulfport - Gulfport-Biloxi International Airport, an airport reporting wind, visibility and sky cover, but no water temperature, 12.6 mi away.
The tide at Cat Island
Cat Island has a diurnal tide: usually one high and one low a day, with the daily rhythm shifting about 50 minutes later each day and fading near the moon's equatorial crossing. This month's predictions average 1.0 high tides a day here. The mean range from lower low to higher high is 1.6 ft, and 1.4 ft between the average high and the average low, a small tide. For the water around it: Northern Gulf tides are diurnal, one high and one low most days with ranges of 1 to 2 ft, so wind and river stage move the water as much as the moon.
About this station
- NOAA predicts tides here from South Pass, station 8760551. High tide comes about 133 min later and low tide about 120 min later than there.
- High tide heights run about 1.23 times the reference.
Datum and source
Heights on this page are feet above mean lower low water (MLLW), the zero NOAA's nautical charts use for soundings. A predicted 0.0 ft low is the average of the lower low each day; a minus tide is water below chart datum, and a 2 ft high means 2 ft more water than the chart shows. NOAA fixes MLLW at Cat Island from the 1983-2001 National Tidal Datum Epoch; mean higher high water is 1.6 ft above it and mean sea level 0.8 ft. These datums are controlled from NOAA's Bay Waveland Yacht Club, MS gauge. Source: NOAA CO-OPS station 8745799, established 1979, gauge removed 1980. The tide times and heights are published as time and height offsets from its reference gauge; TidalMap republishes them daily and does not alter them.

TidalMapMonthly tide calendar
🌊 Biggest flood tides at Cat Island this month: Oct 1, Oct 2, Oct 3, Oct 4, Oct 27, Oct 29, Oct 30, Oct 31. These spring highs push water up into the grass and over the oyster rock; prime for poling into flooded marsh for tailing reds.
🔻 Negative (minus) low tides at Cat Island this month: Oct 28, Oct 29, Oct 30, Oct 31. These drain the flats and expose the oyster rock, prime for sight-fishing and clamming.
Best fishing times (solunar)
Major and minor solunar windows for Cat Island, peak feeding activity is around the moon overhead/underfoot (majors) and moonrise/moonset (minors). Score is the day's activity coefficient (0–100).
