Where Glen Cove, Hempstead Harbor is
Glen Cove, Hempstead Harbor sits at 40.8633° N, 73.6550° W on Long Island Sound, at Glen Cove, NY. The station here is a historical NOAA reference station: a gauge measured the tide at this spot from 1990 until 1990, and NOAA still publishes harmonic predictions from that record. There is no live reading here today. The closest gauge measuring live water level is Kings Point (NOAA 8516945), 6.8 mi away, and the tide here runs on nearly the same clock. The nearest weather station is Kings Point, NY, a shore station reporting wind and, at most sites, water temperature, 6.8 mi away.
The tide at Glen Cove, Hempstead Harbor
Glen Cove, Hempstead Harbor has a semidiurnal tide: two highs and two lows a day of about the same size, roughly 12 hours 25 minutes apart. This month's predictions average 1.9 high tides a day here. The mean range from lower low to higher high is 7.9 ft, and 7.3 ft between the average high and the average low, a large tide. On an average day the higher high tops the lower high by 0.4 ft and the lower low sits 0.2 ft below the other low. For the water around it: Sound tides are semidiurnal and grow from 2 to 3 ft at the eastern entrance to 7 ft or more at the western end.
About this station
- High tide reaches Glen Cove, Hempstead Harbor about 3.7 hours after the moon passes overhead. That lag is local, which is why high water does not line up with the moon.
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 Glen Cove, Hempstead Harbor from the 1983-2001 National Tidal Datum Epoch; mean higher high water is 7.9 ft above it and mean sea level 3.9 ft. The land survey datum NAVD88, the zero on topographic maps and flood maps, is 4.2 ft above MLLW here, so a water level on this page converts to NAVD88 by subtracting that amount. These datums are controlled from NOAA's New Rochelle, Ny gauge. Source: NOAA CO-OPS station 8516614, established 1990, gauge removed 1990. The tide times and heights are NOAA's official harmonic predictions for this station; TidalMap republishes them daily and does not alter them.
