About the tides at Southwest Harbor

Expect two roughly equal high tides a day at Southwest Harbor, each arriving about 50 minutes later than the day before. With a mean range of about 9.9 ft, the shoreline here changes a lot between high and low water. Over the next two weeks the biggest daily range, 12.3 ft, comes today, and the smallest, 9.3 ft, on Monday.

Tides here are worked out from the reference station at Bar Harbor, with NOAA time and height corrections. Times are good for planning, but local wind can shift them. The nearest other station is Bass Harbor, 3 mi away. For tidal currents, see Casco Passage, east end, Blue Hill Bay.

Predictions are based on Bar Harbor.
