Where Snug Harbor, Chisik Island is
Snug Harbor, Chisik Island sits at 60.1075° N, 152.5817° W on Cook Inlet, off the Gulf of Alaska, about 31 mi west of Happy Valley, AK. The station here is a historical NOAA reference station: a gauge measured the tide at this spot from 1979 until 2024, and NOAA still publishes harmonic predictions from that record. There is no live reading here today. The closest gauge measuring live water level is Seldovia, Kachemak Bay (NOAA 9455500), 55.0 mi away, and high and low water here run on average about 66 min later than there.
The tide at Snug Harbor, Chisik Island
Snug Harbor, Chisik Island has a semidiurnal tide: two highs and two lows a day of about the same size, roughly 12 hours 25 minutes apart. This month's predictions average 1.9 high tides a day here. The mean range from lower low to higher high is 15.9 ft, and 13.3 ft between the average high and the average low, a very large tide, among the biggest in the United States. On an average day the higher high tops the lower high by 0.8 ft and the lower low sits 1.8 ft below the other low. For the water around it: Cook Inlet has some of the largest tides in the United States, mixed semidiurnal with ranges near 30 ft at the head of the inlet.
About this station
- High tide reaches Snug Harbor, Chisik Island about 12.2 hours after the moon passes overhead. That lag is local, which is why high water does not line up with the moon.
Datum and source
Heights on this page are feet above mean lower low water (MLLW), the zero NOAA's nautical charts use for soundings. A predicted 0.0 ft low is the average of the lower low each day; a minus tide is water below chart datum, and a 2 ft high means 2 ft more water than the chart shows. NOAA fixes MLLW at Snug Harbor, Chisik Island from the 2012-2016 National Tidal Datum Epoch; mean higher high water is 15.9 ft above it and mean sea level 8.5 ft. The land survey datum NAVD88, the zero on topographic maps and flood maps, is 3.7 ft above MLLW here, so a water level on this page converts to NAVD88 by subtracting that amount. These datums are controlled from NOAA's Seldovia, AK gauge. Source: NOAA CO-OPS station 9456173, established 1979, gauge removed 2024. The tide times and heights are NOAA's official harmonic predictions for this station; TidalMap republishes them daily and does not alter them.
