Station Hyannis Port (NOAA 8447605). Predicted astronomical tide: wind, river flow and storms can move the real water by a foot or more. 3.6 ft is the average daily range here.
Published by Radif Partners · How the tides are computed · predictions downloaded October 13, 2026
Tide times for Hyannis come from the National Ocean Service prediction for station 8447605, Hyannis Port. The tide here is semidiurnal: two highs and two lows of similar height every day, about six hours and a quarter apart, with an average daily range of 3.6 ft. Around the new and full moon the range grows to about 4.5 ft on one day in ten, and at the quarter moons it shrinks to 2.7 ft. Heights are in feet above Mean Lower Low Water, the zero of nautical charts, so a negative number is water below that zero: 157 of the 457 days from October 1, 2026 to December 31, 2027 have one, down to -0.7 ft on December 25, 2026. The highest predicted tide of that period is 4.7 ft on July 5, 2027. Clock times are Eastern Time, daylight saving time included.
A small tide on the Sound
Hyannis averages only 3.6 ft between low and high, against 10.0 ft in Plymouth on Cape Cod Bay. The reason lies offshore: Nantucket Sound is close to a point where the Atlantic's twice-daily tide wave nearly cancels itself, so the water level hardly swings while the currents in the sound stay strong. For swimmers at Kalmus or Craigville Beach, the beach width changes far less over a day than on the bay side.
Barnstable Harbor, six miles and a world away
Barnstable Harbor, straight north across the Cape, is predicted by NOAA from Boston with high water 11 minutes later and the full Boston range, close to ten feet. Its marshes and Sandy Neck flats drain spectacularly, while Hyannis barely moves. To the east and west along the south shore, the rivers lag: the Bass River in South Yarmouth runs nearly two hours behind Boston at 29 percent of its height, and Cotuit and Poponesset are similar.
Ferries and moorings
Ferry schedules to Nantucket and Martha's Vineyard do not wait for the tide, and the harbor is dredged for them. For small boats in the inner harbor and in Lewis Bay, though, a negative low such as -0.7 ft on December 25, 2026 exposes the shallows. The Nantucket page shows the tide at the other end of the crossing.
Highest and lowest tides at Hyannis, 2026 to 2027
The six highest highs and six lowest lows predicted for Hyannis Port between October 1, 2026 and December 31, 2027, one per day. The high-water dates are the king tides of this station; the low-water dates are the best days to see the flats, bars and tide pools.
