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 Oyster Landing (N Inlet Estuary), SC (a Hohonu community gauge), 7.9 mi away, and high and low water here run on average about 20 min earlier than there.
The tide at South Island Plantation (C.G. Station)
South Island Plantation (C.G. Station) has a semidiurnal tide: two highs and two lows a day of about the same size, roughly 12 hours 25 minutes apart. This month's predictions average 1.9 high tides a day here. The mean range from lower low to higher high is 4.3 ft, and 3.8 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 0.2 ft below the other low. For the water around it: Lowcountry tides are semidiurnal, two highs and two lows a day of near equal size, and the range grows toward Georgia, where 6 to 9 ft is normal.
About this station
- High tide reaches South Island Plantation (C.G. Station) about 1.0 hours after the moon passes overhead. That lag is local, which is why high water does not line up with the moon.
- Highest water on record: 9.2 ft on Sep 22, 1989.
- Lowest on record: -3.7 ft on Mar 13, 1993.
- NOAA predicts tides here from Charleston (Customhouse Wharf), station 8665530. High tide comes about 35 min later and low tide about 36 min later than there.
- High tide heights run about 0.74 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 South Island Plantation (C.G. Station) from the 1983-2001 National Tidal Datum Epoch; mean higher high water is 4.3 ft above it and mean sea level 2.1 ft. The land survey datum NAVD88, the zero on topographic maps and flood maps, is 2.2 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 Charleston, SC gauge. Source: NOAA CO-OPS station 8662746, established 1974, gauge removed 1997. 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.
