Where Old Harbor is
Old Harbor sits at 57.2028° N, 153.3039° W on the Gulf of Alaska, at Old Harbor, AK, in Kodiak Island. The station here is a historical NOAA reference station: a gauge measured the tide at this spot from 2009 until 2009, 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), 41.3 mi away, and high and low water here run on average about 30 min earlier than there. The nearest weather station is Akhiok, an airport reporting wind, visibility and sky cover, but no water temperature, 37.7 mi away.
The tide at Old Harbor
Old Harbor 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 8.3 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 0.6 ft and the lower low sits 1.2 ft below the other low. For the water around it: Gulf of Alaska tides are mixed semidiurnal, two unequal highs a day with ranges of 8 to 15 ft.
About this station
- High tide reaches Old Harbor about 10.3 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 Old Harbor from the 2012-2016 National Tidal Datum Epoch; mean higher high water is 8.3 ft above it and mean sea level 4.4 ft. These datums are controlled from NOAA's Kodiak Island, AK gauge. Source: NOAA CO-OPS station 9457527, established 2009, gauge removed 2009. The tide times and heights are NOAA's official harmonic predictions for this station; TidalMap republishes them daily and does not alter them.
