Orange: measured by NOAA's sensor, last 24 hours (6-minute data, preliminary). Dashed: predicted tide, through the next 24 hours. The prediction contains only the astronomical tide; wind, air pressure and river flow move the real water level away from it.
Cowen Creek, Rt. 21 bridge is a subordinate station: NOAA computes its tides from Fort Pulaski, Savannah River Entrance with fixed time and height corrections.

On Tuesday, October 27, high tide at Cowen Creek, Rt. 21 bridge is at 10:10 AM (8.9 ft) and 10:36 PM (7.5 ft); low tide is at 4:15 AM (-0.1 ft) and 4:55 PM (0.2 ft) (EDT, heights above MLLW). The table above lists the next 7 days.
The highest predicted tide in the next 12 months is 8.9 ft on October 27, 2026 at 10:10 AM. The largest tides fall a day or two after a full or new moon, especially when the Moon is closest to Earth.
Yes — on 134 days in the next 12 months the low tide drops below 0 ft (MLLW). The lowest is -1.0 ft on January 23, 2027 at 3:20 AM. Minus tides expose the most shoreline, which is why tide-poolers look for them.
Station local time (EDT at the time this page was built), with daylight saving time applied where the area observes it — the same convention as NOAA's own tide tables.
From NOAA CO-OPS, the U.S. government tide station network (tidesandcurrents.noaa.gov); the predictions are public domain. Cowen Creek, Rt. 21 bridge is a subordinate station: NOAA derives its times and heights from the reference station Fort Pulaski, Savannah River Entrance with fixed corrections. The curve between highs and lows is our interpolation. This page is not for navigation.
