Where Green Island is
Green Island sits at 40.6233° N, 73.5017° W on the Mid-Atlantic coast, about 1 mi south of Wantagh, NY. The station here is a historical NOAA reference station: a gauge measured the tide at this spot from 2013 until 2014, 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), 18.9 mi away, and high and low water here run on average about 188 min earlier than there. The nearest weather station is Farmingdale - Republic Airport, an airport reporting wind, visibility and sky cover, but no water temperature, 8.9 mi away.
The tide at Green Island
Green Island 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 3.5 ft, and 3.1 ft between the average high and the average low, a moderate tide. On an average day the higher high tops the lower high by 0.2 ft and the lower low sits 0.2 ft below the other low. For the water around it: Mid-Atlantic tides are semidiurnal, two highs and two lows a day of about equal size, with ranges of 3 to 5 ft on the ocean and less inside the bays.
About this station
- High tide reaches Green Island about 0.8 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 Green Island from the 1983-2001 National Tidal Datum Epoch; mean higher high water is 3.5 ft above it and mean sea level 1.8 ft. These datums are controlled from NOAA's Sandy Hook, NJ gauge. Source: NOAA CO-OPS station 8516155, established 2013, gauge removed 2014. The tide times and heights are NOAA's official harmonic predictions for this station; TidalMap republishes them daily and does not alter them.

TidalMapMonthly tide calendar
🌊 Biggest flood tides at Green Island this month: Nov 23, Nov 24, Nov 25, Nov 26, Nov 27, Nov 28. 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 Green Island this month: Nov 23, Nov 24, Nov 25, Nov 26, Nov 27, Nov 28. 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 Green Island, peak feeding activity is around the moon overhead/underfoot (majors) and moonrise/moonset (minors). Score is the day's activity coefficient (0–100).
