Today on the water at Harbor River Bridge
Today at Harbor River Bridge: high tide at 12:39 AM (6.1 ft) and 1:09 PM (7.1 ft), low tide at 6:40 AM (0.4 ft) and 7:28 PM (1.0 ft). The National Weather Service forecast for today is partly sunny with NE winds 9 to 22 mph, 73°F. Wind that strong can hold water in or push it out, so the real tide may run above or below these predictions. In effect now: Rip Current Statement. Sunrise is at 7:37 AM and sunset at 6:33 PM.
| Period | Forecast | Wind | Temp |

Where Harbor River Bridge is
Harbor River Bridge sits at 32.4033° N, 80.4533° W on the Carolina and Georgia coast on the South Atlantic Bight, at Harbor Island, SC, in Beaufort County. 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 Fripp Island, SC (a Hohonu community gauge), 7.1 mi away, and high and low water here run on average about 12 min later than there. The nearest weather station is Fripp Nearshore, SC (FRP2), an offshore buoy reporting wind, waves and water temperature, 9.0 mi away.
The tide at Harbor River Bridge
Harbor River Bridge 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 6.7 ft, and 6.1 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 Harbor River Bridge about 0.6 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: 8.3 ft on Nov 2, 1975.
- Lowest on record: -3.5 ft on Nov 13, 1974.
- NOAA predicts tides here from Fort Pulaski, Savannah River Entrance, station 8670870. High tide comes about 3 min later and low tide about 6 min earlier than there.
- High tide heights run about 0.88 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 Harbor River Bridge from the 1983-2001 National Tidal Datum Epoch; mean higher high water is 6.7 ft above it and mean sea level 3.4 ft. The land survey datum NAVD88, the zero on topographic maps and flood maps, is 3.7 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 8668146, established 1974, gauge removed 1976. 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 Harbor River Bridge this month: Oct 10, Oct 11, Oct 25, 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.
🔻 Negative (minus) low tides at Harbor River Bridge this month: Oct 27, Oct 28, Oct 29. 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 Harbor River Bridge, peak feeding activity is around the moon overhead/underfoot (majors) and moonrise/moonset (minors). Score is the day's activity coefficient (0–100).
