About this station
Ellsworth, Union River is one of NOAA's reference tide stations — its predictions are computed directly from harmonic analysis of water levels observed here, and other nearby stations are calculated from it.
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.
