About the tides at Big Spanish Key

Tides here are mixed. On average the two daily highs differ by 1.2 ft, so check which low is the lower one before you head out. On a typical day the water moves about 2.8 ft between high and low. That is larger than most Florida stations on this site. Over the next two weeks the biggest daily range, 4.5 ft, comes today, and the smallest, 3.4 ft, on October 8.

Big Spanish Key is a subordinate station, so NOAA publishes only its high and low times and heights. The nearest other station is Howe Key, northwest end, 2 mi away, where high tide comes about 10 min later. For tidal currents, see No Name Key, northeast of.
