About the Tides at Port McArthur
Port McArthur 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 10.0 feet.
Over the next two weeks the biggest tides come on Monday, November 9, when the water moves about 12.7 feet. The lowest water is -1.0 ft on Monday, November 9 at 6:45 PM, and the highest is 11.7 ft on Monday, November 9 at 11:52 AM. A minus tide like that uncovers the most beach, flats and tide pools.
NOAA works out the times here from its reference station at Sitka, adjusted for this location.
