Where Prudhoe Bay is
Prudhoe Bay sits at 70.4114° N, 148.5317° W on Alaska's Arctic coast, at Prudhoe Bay, AK. The station here is a live gauge in NOAA's National Water Level Observation Network, the reference network the rest of the coast's tide predictions are tied to. It has been in NOAA's records since 1990. The nearest weather station is Prudhoe Bay, a tide-station weather package reporting wind and water temperature, right at this station.
The tide at Prudhoe Bay
Prudhoe Bay has a mixed tide: two highs and two lows a day, but of unequal size, so one low each day drains a little 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 0.7 ft, and 0.5 ft between the average high and the average low, a small tide. On an average day the higher high tops the lower high by 0.1 ft and the lower low sits 0.1 ft below the other low. For the water around it: Tides along the Chukchi and Beaufort seas are small, often under a foot, and wind and ice move the water more than the moon does.
About this station
- High tide reaches Prudhoe Bay about 9.6 hours after the moon passes overhead. That lag is local, which is why high water does not line up with the moon.
- Highest water on record: 4.8 ft on Aug 11, 2000.
- Lowest on record: -4.0 ft on May 12, 2021.
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 Prudhoe Bay from the 1983-2001 National Tidal Datum Epoch; mean higher high water is 0.7 ft above it and mean sea level 0.3 ft. Source: NOAA CO-OPS station 9497645, a National Water Level Observation Network gauge, established 1990. The tide times and heights are NOAA's official harmonic predictions for this station; TidalMap republishes them daily and does not alter them. The observed line is the gauge's own six-minute water level feed.
