Where Cedar Beach is
Cedar Beach sits at 40.9650° N, 73.0433° W on Long Island Sound, at Mount Sinai, NY. The station here is a historical NOAA reference station: a gauge measured the tide at this spot from 1988 until 1989, and NOAA still publishes harmonic predictions from that record. There is no live reading here today. The closest gauge measuring live water level is Bridgeport (NOAA 8467150), 16.3 mi away, and high and low water here run on average about 7 min later than there. The nearest weather station is Islip, Long Island Mac Arthur Airport, an airport reporting wind, visibility and sky cover, but no water temperature, 12.2 mi away.
The tide at Cedar Beach
Cedar Beach 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 7.0 ft, and 6.4 ft between the average high and the average low, a large tide. On an average day the higher high tops the lower high by 0.3 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 Cedar Beach about 3.9 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 Cedar Beach from the 1983-2001 National Tidal Datum Epoch; mean higher high water is 7.0 ft above it and mean sea level 3.4 ft. These datums are controlled from NOAA's Port Jefferson, Ny gauge. Source: NOAA CO-OPS station 8514422, established 1988, gauge removed 1989. The tide times and heights are NOAA's official harmonic predictions for this station; TidalMap republishes them daily and does not alter them.

🌊 Biggest flood tides at Cedar Beach this month: Nov 7, Nov 8, Nov 22, 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 Cedar Beach this month: Nov 8, Nov 22, 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.
