Where Chirikof Island is
Chirikof Island sits at 55.8083° N, 155.7400° W on the Alaska Peninsula and Shumagin Islands, about 96 mi southwest of Akhiok, AK. The station here is a historical NOAA reference station: a gauge measured the tide at this spot from 2006 until 2006, and NOAA still publishes harmonic predictions from that record. There is no live reading here today. The closest gauge measuring live water level is Alitak, Lazy Bay (NOAA 9457804), 94.5 mi away, and high and low water here run on average about 22 min earlier than there. The nearest weather station is Alitak, AK, a shore station reporting wind and, at most sites, water temperature, 94.5 mi away.
The tide at Chirikof Island
Chirikof Island has a mixed tide: two highs and two lows a day, but of unequal size, so one low each day drains noticeably lower than the other. This month's predictions average 1.9 high tides a day here. The mean range from lower low to higher high is 8.8 ft, and 6.5 ft between the average high and the average low, a large tide. On an average day the higher high tops the lower high by 0.8 ft and the lower low sits 1.5 ft below the other low. For the water around it: Tides here are mixed: 8 to 12 ft and semidiurnal on the Pacific side of the peninsula, smaller and closer to one high a day on the Bristol Bay side.
About this station
- High tide reaches Chirikof Island about 10.4 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 Chirikof Island from the 2012-2016 National Tidal Datum Epoch; mean higher high water is 8.8 ft above it and mean sea level 4.6 ft. These datums are controlled from NOAA's Kodiak Island, AK gauge. Source: NOAA CO-OPS station 9458293, established 2006, gauge removed 2006. The tide times and heights are NOAA's official harmonic predictions for this station; TidalMap republishes them daily and does not alter them.
