On Tuesday, October 27, high tide at Marcus Hook, Pa. is at 1:12 AM (5.9 ft) and 1:28 PM (6.9 ft); low tide is at 8:12 AM (0.5 ft) and 9:02 PM (0.4 ft) (EDT, heights above MLLW). The table above lists the next 7 days.
The highest predicted tide in the next 12 months is 7.1 ft on July 5, 2027 at 1:22 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 73 days in the next 12 months the low tide drops below 0 ft (MLLW). The lowest is -0.7 ft on January 23, 2027 at 7:57 PM. 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. The curve between highs and lows is our interpolation. This page is not for navigation.
