About the Tides at Main Key
Main Key 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 0.3 feet. Tides here are small, so wind and river flow can move the water as much as the tide does.
Over the next two weeks the biggest tides come on Sunday, November 8, when the water moves about 0.5 feet. The lowest water is 0.1 ft on Sunday, November 8 at 7:13 AM, and the highest is 0.6 ft on Saturday, November 7 at 12:04 PM.
