The tide at Baltimore, Fort McHenry
Baltimore, Fort McHenry has a mixed tide: two highs and two lows a day, but of unequal size, so one low each day drains a little lower than the other. This month's predictions average 2.0 high tides a day here. The mean range from lower low to higher high is 1.7 ft, and 1.1 ft between the average high and the average low, a small tide. On an average day the higher high tops the lower high by 0.3 ft and the lower low sits 0.2 ft below the other low. For the water around it: Chesapeake tides are semidiurnal but small, 1 to 3 ft, and arrive many hours after the ocean tide as the wave works up the bay and its rivers.
About this station

- Lowest on record: -5.1 ft on Jan 24, 1908.
- The National Weather Service counts 3.4 ft as minor flooding here, 4.6 ft as moderate and 6.0 ft as major.
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 Baltimore, Fort McHenry from the 1983-2001 National Tidal Datum Epoch; mean higher high water is 1.6 ft above it and mean sea level 0.8 ft. The land survey datum NAVD88, the zero on topographic maps and flood maps, is 0.8 ft above MLLW here, so a water level on this page converts to NAVD88 by subtracting that amount. Source: NOAA CO-OPS station 8574680, established 1902. The tide times and heights are NOAA's official harmonic predictions for this station; TidalMap republishes them daily and does not alter them. The observed line is the gauge's own six-minute water level feed.
