About this station
NOAA builds the predictions for Mattapoisett, Mattapoisett Harbor from the NEWPORT station: high tides about 1.09× the height, 11 min later; low tides about the same height, 20 min later.
Rocky shores and the country's biggest northern ranges: Eastport flirts with 20 ft, and the Gulf of Maine funnels weather as much as tide. Harbors here float — or sit in the mud — on the moon's schedule.
