About this station
NOAA builds the predictions for Green Island, Petit Manan Bar from the PORTLAND station: high tides about 1.16× the height, 28 min earlier; low tides about 1.16× the height, 24 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.
