Where Keyport is
Keyport sits at 40.4400° N, 74.1983° W on New York Harbor and the Hudson River, at Keansburg, NJ. The station here is a subordinate tide prediction point. NOAA has no gauge in the water at this spot; its times and heights are published as offsets from a reference gauge, named below. The closest gauge measuring live water level is Sandy Hook, Fort Hancock (NOAA 8531680), 10.1 mi away, and the tide here runs on nearly the same clock. The nearest weather station is Sandy Hook, NJ, a shore station reporting wind and, at most sites, water temperature, 10.1 mi away.
The tide at Keyport
Keyport 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 5.6 ft, and 5.0 ft between the average high and the average low, a moderate 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: Harbor tides are semidiurnal, two highs a day near 4 to 5 ft, and the tide runs all the way up the Hudson to Troy.
About this station
- High tide reaches Keyport about 0.2 hours after the moon passes overhead. That lag is local, which is why high water does not line up with the moon.
- NOAA predicts tides here from Sandy Hook, Fort Hancock, station 8531680. High tide comes about 4 min earlier and low tide about 6 min later than there.
- High tide heights run about 1.08 times the reference.
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 Keyport from the 1983-2001 National Tidal Datum Epoch; mean higher high water is 5.6 ft above it and mean sea level 2.8 ft. The land survey datum NAVD88, the zero on topographic maps and flood maps, is 2.9 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 Sandy Hook, NJ gauge. Source: NOAA CO-OPS station 8531545, established 1975, gauge removed 1977. The tide times and heights are published as time and height offsets from its reference gauge; TidalMap republishes them daily and does not alter them.

TidalMapMonthly tide calendar
🌊 Biggest flood tides at Keyport this month: Nov 7, Nov 8, Nov 9, Nov 23, Nov 24, Nov 25, Nov 26, Nov 27. These spring highs push water up into the grass and over the oyster rock; prime for poling into flooded marsh for tailing reds.
🔻 Negative (minus) low tides at Keyport this month: Nov 22, Nov 23, Nov 24, Nov 25, Nov 26, Nov 27, Nov 28, Nov 29. These drain the flats and expose the oyster rock, prime for sight-fishing and clamming.
Best fishing times (solunar)
Major and minor solunar windows for Keyport, peak feeding activity is around the moon overhead/underfoot (majors) and moonrise/moonset (minors). Score is the day's activity coefficient (0–100).
