About this station
NOAA builds the predictions for Guilford Harbor from the BRIDGEPORT station: high tides about 0.77× the height, 11 min earlier; low tides about 0.96× the height, 21 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.
