About the tides at Big Spanish Key
Tides here are mixed. On average the two daily highs differ by 1.3 ft, so check which low is the lower one before you head out. The pattern follows the reference station at Key West. On a typical day the water moves about 2.6 ft between high and low. That is larger than most Florida stations on this site. From the average lower low to the average higher high, the difference is 3.2 ft. Over the next two weeks the biggest daily range, 4.4 ft, comes today, and the smallest, 2.3 ft, on November 19. Looking a year ahead, predictions peak at 5.0 ft on October 29 and bottom out at −1.0 ft on January 21.
Tides here are worked out from the reference station at Key West, with NOAA time and height corrections. Times are good for planning, but local wind can shift them. NOAA measured the tide here from 1973 to 1974 to set up these predictions. 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.
Predictions are based on Key West.
