Where Koyuk, Koyuk Inlet is
Koyuk, Koyuk Inlet sits at 64.9312° N, 161.1508° W on the Bering Sea side of Alaska, at Koyuk, AK, in Nome. The station here is a historical NOAA reference station: a gauge measured the tide at this spot from 2020 until 2020, and NOAA still publishes harmonic predictions from that record. There is no live reading here today. The closest gauge measuring live water level is Unalakleet (NOAA 9468333), 73.8 mi away, and high and low water here run on average about 164 min later than there. The nearest weather station is Koyuk, Koyuk Airport, an airport reporting wind, visibility and sky cover, but no water temperature, 0.3 mi away.
The tide at Koyuk, Koyuk Inlet
Koyuk, Koyuk Inlet has a diurnal tide: usually one high and one low a day, with the daily rhythm shifting about 50 minutes later each day and fading near the moon's equatorial crossing. This month's predictions average 1.1 high tides a day here. The mean range from lower low to higher high is 3.0 ft, and 2.5 ft between the average high and the average low, a moderate tide. On an average day the higher high tops the lower high by 0.2 ft and the lower low sits 0.2 ft below the other low. For the water around it: Bering Sea tides are mixed, swinging toward one high a day in Norton Sound and Bristol Bay, and storm surge often matters more than the predicted tide.
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 Koyuk, Koyuk Inlet from the 1983-2001 National Tidal Datum Epoch; mean higher high water is 3.0 ft above it and mean sea level 1.4 ft. The land survey datum NAVD88, the zero on topographic maps and flood maps, is 2.8 ft below MLLW here, so a water level on this page converts to NAVD88 by adding that amount. These datums are controlled from NOAA's Unalakleet, AK gauge. Source: NOAA CO-OPS station 9469031, established 2020, gauge removed 2020. The tide times and heights are NOAA's official harmonic predictions for this station; TidalMap republishes them daily and does not alter them.
