About the tides at Anchorage

Tides here follow a regular twice-daily rhythm. The two daily highs usually differ by only 1.6 ft. The tide range here is very large, about 26.2 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 29.2 ft. The next spring tides peak on October 11, with a range of 32.7 ft. Neap tides follow on Sunday, when the range shrinks to 22.4 ft.

Knik Arm is a NOAA water level station with a live gauge, updated every 6 minutes. Predictions come from the station's own tide records. It was established in 1964. The nearest other station is Port MacKenzie, 2 mi away, where high tide comes about 8 min later. For tidal currents, see Anchorage Shipdock, northwest of.
