Where Offshore St Matthew Island (GNSS Buoy) is
Offshore St Matthew Island (GNSS Buoy) sits at 60.3942° N, 172.4862° W on the Bering Sea side of Alaska, about 209 mi west of Mekoryuk, AK. The station here is a historical NOAA reference station: a gauge measured the tide at this spot from 2025 until 2025, and NOAA still publishes harmonic predictions from that record. There is no live reading here today. The closest gauge measuring live water level is Village Cove, St. Paul Island (NOAA 9464212), 239.2 mi away, and high and low water here run on average about 171 min later than there. The nearest weather station is Hooper Bay, Hooper Bay Airport, an airport reporting wind, visibility and sky cover, but no water temperature, 226.7 mi away.
The tide at Offshore St Matthew Island (GNSS Buoy)
Offshore St Matthew Island (GNSS Buoy) 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 1.7 high tides a day here. The mean range from lower low to higher high is 3.2 ft, and 2.2 ft between the average high and the average low, a moderate tide. On an average day the higher high tops the lower high by 0.3 ft and the lower low sits 0.7 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 Offshore St Matthew Island (GNSS Buoy) from the 1983-2001 National Tidal Datum Epoch; mean higher high water is 3.2 ft above it and mean sea level 1.7 ft. These datums are controlled from NOAA's Village Cove, St Paul Island, AK gauge. Source: NOAA CO-OPS station 9466229, established 2025, gauge removed 2025. The tide times and heights are NOAA's official harmonic predictions for this station; TidalMap republishes them daily and does not alter them.
