About the Tides at Constantine Harbor
Constantine Harbor 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 3.1 feet.
Over the next two weeks the biggest tides come on Thursday, November 12, when the water moves about 3.7 feet. The lowest water is -0.4 ft on Thursday, November 12 at 12:11 AM, and the highest is 3.3 ft on Thursday, November 12 at 12:10 PM. A minus tide like that uncovers the most beach, flats and tide pools.
