About the tides at Green Island

Expect two roughly equal high tides a day at Petit Manan Bar, each arriving about 50 minutes later than the day before. The tide range here is very large, about 10.4 ft on average. Water can come in faster than you can walk across flats. Check the time before you go out. The next spring tides peak today, with a range of 13.1 ft. Neap tides follow on Sunday, when the range shrinks to 9.9 ft.

Green Island is a subordinate station. NOAA predicts its tides by adjusting Portland: highs come about 28 min and lows about 24 min earlier than there. The nearest other station is Prospect Harbor, 8 mi away.

Predictions are based on Portland.
