About the Tides at South Bay Entrance
South Bay Entrance gets just one high tide and one low tide on most days, instead of the two a day many coasts see. On a typical day the water rises and falls about 1.6 feet.
Over the next two weeks the biggest tides come on Tuesday, November 10, when the water moves about 2.0 feet. The lowest water is -0.1 ft on Tuesday, November 10 at 9:04 AM, and the highest is 2.0 ft on Sunday, November 8 at 4:57 PM. A minus tide like that uncovers the most beach, flats and tide pools.
