Where Magnetic Point, Union Bay, Earnest Sound is
Magnetic Point, Union Bay, Earnest Sound sits at 55.7883° N, 132.1909° W on Southeast Alaska's Inside Passage, at Wrangell, AK. 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 Ketchikan (NOAA 9450460), 38.5 mi away, and the tide here runs on nearly the same clock.
The tide at Magnetic Point, Union Bay, Earnest Sound
Magnetic Point, Union Bay, Earnest Sound 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 16.0 ft, and 13.6 ft between the average high and the average low, a very large tide, among the biggest in the United States. On an average day the higher high tops the lower high by 0.9 ft and the lower low sits 1.6 ft below the other low. For the water around it: Inside Passage tides are large and mixed semidiurnal, two highs and two lows a day with ranges of 12 to 20 ft that drive fast currents in the narrows.
About this station
- High tide reaches Magnetic Point, Union Bay, Earnest Sound about 9.5 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 Magnetic Point, Union Bay, Earnest Sound from the 1983-2001 National Tidal Datum Epoch; mean higher high water is 16.0 ft above it and mean sea level 8.3 ft. These datums are controlled from NOAA's Ketchikan, AK gauge. Source: NOAA CO-OPS station 9450753, 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.
