About the tides at Thorne Island

Expect two roughly equal high tides a day at Whale Passage, each arriving about 50 minutes later than the day before. The pattern follows the reference station at Ketchikan, Tongass Narrows. The tide range here is very large, about 13.5 ft on average. Water can come in faster than you can walk across flats. Check the time before you go out. That is larger than most Alaska stations on this site. From the average lower low to the average higher high, the difference is 15.9 ft. In the next 12 months the highest predicted tide here is 19.8 ft on December 24, and the lowest is −4.2 ft on July 5.

Thorne Island is a subordinate station. NOAA predicts its tides by adjusting Ketchikan, Tongass Narrows: highs come about 12 min and lows about 1 min later than there. NOAA measured the tide here from 1967 to 2001 to set up these predictions. The nearest other station is Lake Bay, 3 mi away. For tidal currents, see Key Reef.

Predictions are based on Ketchikan, Tongass Narrows.
