The station here is a historical NOAA reference station: a gauge measured the tide at this spot from 1980 until 2012, and NOAA still publishes harmonic predictions from that record. There is no live reading here today. The closest gauge measuring live water level is Kings Bay, Msf Pier (NOAA 8679598), 42.2 mi away, and high and low water here run on average about 27 min earlier than there. The nearest weather station is Marsh Island, Sapelo Island Reserve, GA, a shore station reporting wind and, at most sites, water temperature, 3.8 mi away.
The tide at Rockdedundy River (Daymark 185)
Rockdedundy River (Daymark 185) 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 7.5 ft, and 6.9 ft between the average high and the average low, a large tide. On an average day the higher high tops the lower high by 0.4 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 Rockdedundy River (Daymark 185) about 0.9 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 Rockdedundy River (Daymark 185) from the 1983-2001 National Tidal Datum Epoch; mean higher high water is 7.5 ft above it and mean sea level 3.8 ft. These datums are controlled from NOAA's Fort Pulaski, GA gauge. Source: NOAA CO-OPS station 8675761, established 1980, gauge removed 2012. The tide times and heights are NOAA's official harmonic predictions for this station; TidalMap republishes them daily and does not alter them.
