About the tides at Mackerel Cove
Expect two roughly equal high tides a day at Swans Island, each arriving about 50 minutes later than the day before. Mackerel Cove sees a mean range of about 10.1 ft. Low tide can expose a wide area, and the return is fast. From the average lower low to the average higher high, the difference is 10.9 ft. Over the next two weeks the biggest daily range, 11.7 ft, comes on November 22, and the smallest, 7.5 ft, on November 19. Looking a year ahead, predictions peak at 13.1 ft on August 4 and bottom out at −2.3 ft on January 23.
Predictions for Mackerel Cove come from this station's own tide records. There is no live sensor, so the table shows forecast only. NOAA measured the tide here in 1994 to set up these predictions. The nearest other station is Burnt Coat Harbor, 2 mi away, where high tide comes about 6 min earlier. For tidal currents, see Casco Passage, east end, Blue Hill Bay.
