About this station
NOAA builds the predictions for Marion, Sippican Harbor from the NEWPORT station: high tides about 1.13× the height, 10 min later; low tides about 1.29× the height, 12 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.
