Where Shell Mound is
Shell Mound sits at 29.2064° N, 83.0697° W on Florida's Gulf coast, about 4 mi northwest of Cedar Key, FL. The station here is a historical NOAA reference station: a gauge measured the tide at this spot from 2022 until 2022, and NOAA still publishes harmonic predictions from that record. There is no live reading here today. The closest gauge measuring live water level is Cedar Key (NOAA 8727520), 5.4 mi away, and high and low water here run on average about 9 min earlier than there.
The tide at Shell Mound
Shell Mound has a mixed tide: two highs and two lows a day, but of unequal size, so one low each day drains noticeably lower than the other. This month's predictions average 1.9 high tides a day here. The mean range from lower low to higher high is 3.7 ft, and 2.8 ft between the average high and the average low, a moderate tide. On an average day the higher high tops the lower high by 0.3 ft and the lower low sits 0.6 ft below the other low. For the water around it: Florida's Gulf coast runs mixed tides: two unequal highs a day near Tampa Bay, trending toward one high a day along the Big Bend and the Panhandle.
About this station
- High tide reaches Shell Mound about 6.1 hours after the moon passes overhead. That lag is local, which is why high water does not line up with the moon.
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 Shell Mound from the 1983-2001 National Tidal Datum Epoch; mean higher high water is 3.7 ft above it and mean sea level 2.0 ft. The land survey datum NAVD88, the zero on topographic maps and flood maps, is 2.3 ft above MLLW here, so a water level on this page converts to NAVD88 by subtracting that amount. These datums are controlled from NOAA's Cedar Key, FL gauge. Source: NOAA CO-OPS station 8727535, established 2022, gauge removed 2022. The tide times and heights are NOAA's official harmonic predictions for this station; TidalMap republishes them daily and does not alter them.

🌊 Biggest flood tides at Shell Mound this month: Oct 1, Oct 11, Oct 12, Oct 13, Oct 26, Oct 27, Oct 28, Oct 29, Oct 30. These spring highs push water up into the grass and over the oyster rock; prime for poling into flooded marsh for tailing reds.
