About the tides at Porpoise Key

Tides here are mixed. On average the two daily highs differ by 0.4 ft, so check which low is the lower one before you head out. Water here rises and falls only about 0.7 ft on an average day. A strong onshore wind can push levels above the prediction. That is smaller than most Florida stations on this site. Over the next two weeks the biggest daily range, 1.6 ft, comes today, and the smallest, 0.9 ft, on October 7.

Porpoise Key is a subordinate station, so NOAA publishes only its high and low times and heights. The nearest other station is Mayo Key, 1 mi away, where high tide comes about 12 min later. For tidal currents, see No Name Key, northeast of.
