About Fort McHenry Marsh tides
Fort McHenry Marsh is a NOAA harmonic tide station (8574683): its predictions come from the tidal constituents NOAA derived from water levels measured at this spot. Heights are in feet above MLLW (Mean Lower Low Water), the datum of US nautical charts, so they line up with charted depths.
In the next 30 days, Fort McHenry Marsh has two highs and two lows on 27 days and three turns on 3 days, and the daily range runs from 0.6 to 2.1 ft. That is a mixed tide: two highs and two lows on most days, of clearly different heights.
Use the curve above to time a harbor entrance, a beach walk, fishing a moving tide or clearing a shallow bar, and remember that wind, air pressure and river flow can push the real water level above or below the prediction. The daily tidal range in the tables shows how much water moves each day: bigger ranges around the new and full moon mean stronger currents.
The latest water temperature near Fort McHenry Marsh is about 72°F, from NOAA station 8574680, 0.5 mi away, at 2:00 AM EST. Water temperature shapes where fish hold and feed, and tells you what to wear in the water, so check it alongside the tide before you head out.
Frequently asked
What time is high tide in Fort McHenry Marsh today?+
Today (Sunday, November 1), high tide at Fort McHenry Marsh is at 12:16 AM (1.7 ft), 11:16 AM (1.1 ft). Heights are referenced to MLLW (Mean Lower Low Water).
What time is low tide in Fort McHenry Marsh today?+
Today, low tide at Fort McHenry Marsh is at 6:33 AM (0.4 ft), 5:42 PM (0.2 ft).
What tidal datum do these Fort McHenry Marsh tide heights use?+
All heights are given in feet relative to MLLW (Mean Lower Low Water), the standard NOAA chart datum for US tidal waters. A tide of 0.0 ft equals the chart datum; negative tides fall below it.
How accurate are these tide predictions?+
Fort McHenry Marsh is a NOAA harmonic station (8574683), so these are NOAA's harmonic predictions for this spot, which are very accurate for the astronomical tide. Real water levels can still differ with wind, air pressure and river flow, so check conditions before you get underway.
What is the water temperature at Fort McHenry Marsh?+
The latest water temperature near Fort McHenry Marsh is about 72°F, from NOAA station 8574680, 0.5 mi away, at 2:00 AM EST. Water temperature drives fish behavior and tells you what to wear in the water, so it's worth checking alongside the tide.
