About this station

NOAA builds the predictions for Cohasset Harbor (White Head) from the BOSTON station: high tides about 0.92× the height, 4 min later; low tides about 0.92× the height, 2 min earlier.

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.
