About the Tides at Kelp Island Passage
Kelp Island Passage 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 13.2 feet.
Over the next two weeks the biggest tides come on Monday, November 9, when the water moves about 17.5 feet. The lowest water is -1.4 ft on Monday, November 9 at 6:41 PM, and the highest is 16.1 ft on Sunday, November 8 at 11:29 AM. A minus tide like that uncovers the most beach, flats and tide pools.
