Bar Harbor, ME tide times

Predictions: NOAA CO-OPS station 8413320 — heights relative to MLLW.

Harmonic prediction from the official tide authority. Very high accuracy under normal conditions; storm surge may shift actual water level. Not for navigation.

Marine-conditions data not available for this station. Wind, swell and water temperature ride along with Open-Meteo Marine; gauge-only stations (e.g. UK EA Flood) publish water level only.

The angler tradition for major/minor fishing windows: major ≈3-hour windows around moon transit and opposition; minor ≈2-hour windows around moonrise and moonset. Times are America/New York local. Folk tradition, not a scientific forecast.

Next spring tide on Sun 17 May (range 4.5m / 14.8ft). Last neap on Fri 15 May. Next neap on Mon 25 May.

Spring tides cluster around new and full moons (biggest swings). Neap tides land on quarter moons (smallest swings). See the spring tide and neap tide glossary entries for the why.

Bar Harbor sits on the eastern shore of Mount Desert Island, the granite mass that anchors Acadia National Park on the central Maine coast. The tide here is large and gets larger the further north-east you go, building toward the world-record swings at the head of the Bay of Fundy a few hundred kilometres further east. Mean range at the Bar Harbor gauge is about 3.1 metres, climbing past 3.7 on spring tides, with neaps near 2.4. The pattern is cleanly semidiurnal, two highs and two lows of comparable size, twelve and a half hours apart. The geography of Frenchman Bay and the funnel-shape of the broader Gulf of Maine amplify the open-Atlantic signal. The most photographed feature of the swing is the Bar that gives the town its name — a gravel sandbar between the harbour and Bar Island that emerges across the lower half of every cycle and lets you walk over to the island for an hour or two either side of low water. The cycle catches visitors out: the bar covers fast on the flood. Predictions on this page come from NOAA CO-OPS station 8413320. Nor'easter storm surge in winter can stack 30 cm or more above predicted.
