About the tide at Prudhoe Bay

It is a harmonic reference station (predicted directly from its own tidal constituents).

Prudhoe Bay has a mixed semidiurnal tide: usually two highs and two lows a day, of noticeably unequal height (on average the day's two highs differ by 0.2 ft and its two lows by 0.2 ft). The average rise or fall between high and low tide is 0.5 ft, growing to about 0.9 ft at spring tides (around new and full moon) and shrinking to about 0.3 ft at neap tides (around the quarter moons). The highest tide predicted in the next 12 months is 1.4 ft on August 6, 2027 at 4:14 AM; the lowest is -0.5 ft on April 10, 2027 at 9:14 AM, and 295 low tides in that period drop below zero (MLLW).
