About this station
NOAA builds the predictions for Wychmere Harbor from the BOSTON station: high tides about 0.39× the height, 52 min later; low tides about 0.39× the height, 25 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.
