Maine Tide Charts

High tide arrives at a different time at each station. Androscoggin River entrance reaches 5.2 ft at 3:48 pm; Back Cove reaches 9.7 ft at 1:26 pm; Back River reaches 10.0 ft at 1:58 pm. The table above lists the next high and the next low for all 111 Maine stations.

Pettegrove Point, Dochet Island, where high and low water differ by 20.7 ft today. The smallest of the 111 Maine stations with a range today is Brunswick, Androscoggin River at 3.9 ft. Range varies along a coast because the shape of a bay or estuary amplifies or damps the same ocean tide.

Yes, at Androscoggin River entrance, Back Cove, Back River and 67 others. The lowest is -0.21 ft at 8:46 pm. A minus tide is water below mean lower low water, the zero point for US predictions, and it exposes ground that is normally covered.

Not all alike. 109 are semidiurnal and 2 are mixed semidiurnal. Each station page classifies itself from its own predictions rather than from a regional rule, because the pattern changes along a single coast.

NOAA states roughly ten minutes on timing and half a foot on height for a reference station in ordinary weather. 30 of the 111 stations here are reference stations; the rest are subordinate, with times and heights derived from one by a published offset, so expect a little more spread. Weather is the bigger factor either way. A storm surge or a strong onshore wind can raise real water well above the prediction, which is astronomy only.
