Where Hyannis Port is
Hyannis Port sits at 41.6317° N, 70.3000° W on the southern New England coast, at Barnstable Town, MA, in Barnstable County. The station here is a historical NOAA reference station: a gauge measured the tide at this spot from 1983 until 1994, and NOAA still publishes harmonic predictions from that record. There is no live reading here today. The closest gauge measuring live water level is Chatham Harbor, Aunt Lydias Cove (NOAA 8447435), 18.4 mi away, and high and low water here run on average about 16 min earlier than there. The nearest weather station is Hyannis, Barnstable Municipal-Boardman Airport, an airport reporting wind, visibility and sky cover, but no water temperature, 3.2 mi away.
The tide at Hyannis Port
Hyannis Port 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 3.8 ft, and 3.2 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 0.3 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 Hyannis Port about 4.7 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 Hyannis Port from the 1983-2001 National Tidal Datum Epoch; mean higher high water is 3.8 ft above it and mean sea level 1.9 ft. These datums are controlled from NOAA's Nantucket Island, MA gauge. Source: NOAA CO-OPS station 8447605, established 1983, gauge removed 1994. The tide times and heights are NOAA's official harmonic predictions for this station; TidalMap republishes them daily and does not alter them.
