About the Tides at Apra Harbor
Apra Harbor gets two high tides and two low tides most days, and they are not a matched pair. One high or one low each day is clearly bigger than the other. On a typical day the water rises and falls about 2.2 feet.
Over the next two weeks the biggest tides come on Wednesday, November 11, when the water moves about 2.6 feet. The lowest water is -0.5 ft on Wednesday, November 11 at 2:27 AM, and the highest is 2.3 ft on Saturday, November 7 at 5:57 PM. A minus tide like that uncovers the most beach, flats and tide pools.
NOAA station 1630000 here measures the water live and reports its temperature. Minor flooding starts when the water reaches 3.3 ft.
