Maine tide charts

About Maine tides

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.

Maine has 111 NOAA tide stations — 30 reference stations whose predictions come from harmonic analysis of observations there, and 81 subordinate stations calculated from them. The biggest tidal range in the state is at Pettegrove Point, Dochet Island — 20.5 ft between mean higher high water and mean lower low water.
