Heights in feet above Mean Lower Low Water (MLLW). Dots are NOAA's predicted highs and lows; the line between them is our interpolation. Shaded: night.

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.
On Tuesday, October 27, high tide at Lower Marlboro is at 5:02 AM (1.9 ft) and 5:42 PM (2.3 ft); low tide is at 11:29 AM (0.0 ft) (EDT, heights above MLLW). The table above lists the next 7 days.
The highest predicted tide in the next 12 months is 2.3 ft on November 25, 2026 at 4:23 PM. The largest tides fall a day or two after a full or new moon, especially when the Moon is closest to Earth.
Yes — on 15 days in the next 12 months the low tide drops below 0 ft (MLLW). The lowest is -0.0 ft on September 2, 2027 at 11:55 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. The curve between highs and lows is our interpolation. This page is not for navigation.
