Where Nantucket is
Nantucket sits at 41.2850° N, 70.0967° W on the southern New England coast, at Nantucket, MA. The station here is a live gauge in NOAA's National Water Level Observation Network, the reference network the rest of the coast's tide predictions are tied to. It has been in NOAA's records since 1963. The nearest weather station is Nantucket Island, MA, a shore station reporting wind and, at most sites, water temperature, right at this station.
The tide at Nantucket
Nantucket 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 3.6 ft, and 3.0 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: Tides along Narragansett Bay, Buzzards Bay and the islands are semidiurnal but vary sharply over short distances, from 1 ft on Nantucket Sound to 4 ft in Narragansett Bay.
About this station
- High tide reaches Nantucket about 4.9 hours after the moon passes overhead. That lag is local, which is why high water does not line up with the moon.
- Highest water on record: 7.9 ft on Oct 30, 1991.
- Lowest on record: -2.1 ft on Feb 12, 1981.
- The National Weather Service counts 5.0 ft as minor flooding here, 6.5 ft as moderate and 8.0 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 Nantucket from the 1983-2001 National Tidal Datum Epoch; mean higher high water is 3.6 ft above it and mean sea level 1.8 ft. Source: NOAA CO-OPS station 8449130, a National Water Level Observation Network gauge, established 1963. 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.
