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 pattern follows the reference station at Portland,casco Bay. The tide range here is very large, about 10.3 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 on November 22, with a range of 12.2 ft. Neap tides follow on November 19, when the range shrinks to 8.1 ft. In the next 12 months the highest predicted tide here is 13.4 ft on December 25, and the lowest is −2.1 ft on January 23.

Green Island is a subordinate station. NOAA predicts its tides by adjusting Portland,casco Bay: 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,casco Bay.
