About the Tides at Vaca Key
Vaca 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 0.9 feet.
Over the next two weeks the biggest tides come on Thursday, November 12, when the water moves about 1.3 feet. The lowest water is 0.1 ft on Friday, November 13 at 8:54 AM, and the highest is 1.4 ft on Tuesday, November 10 at 12:06 AM.
NOAA station 8723970 here measures the water live and reports its temperature. Minor flooding starts when the water reaches 2.1 ft.
