Quick answers

When is the next good low tide at Bar Harbor (Acadia)?

Jul 17, 2026 (Fri): a -1.1 ft low at 7:41 AM, walkable from 6:00 AM to 9:15 AM — score 77/100. Computed from NOAA station 8413320 predictions.

How low does the tide need to be at Bar Harbor (Acadia)?

Tidewindow counts a window whenever the predicted height falls below +1.0 ft MLLW, and scores depth from +0.5 ft (0 points) to −2.0 ft (50 points). The lower the tide, the more of the intertidal zone is exposed — minus tides (below 0 ft) are when Bar Island land bridge is at its best.

How many daylight minus tides does Bar Harbor (Acadia) get in the next 30 days?

9 of the next 30 days' 11 minus tides overlap daylight by at least 30 minutes, as of 2026-07-04. The full list is in the table above.

Safety: tide predictions are astronomical forecasts, not observations — wind and swell change actual water levels. Follow posted rules at protected areas, and never turn your back on the ocean. See our methodology for exactly how windows and scores are computed.
