Red tides have been documented along Florida's gulf coast since the 1840’s.

It is important to realize that many people still enjoy the beaches during red tides. Respiratory irritation and dead fish are not always present.People may experience respiratory irritation (coughing, sneezing, and tearing) when the red tide organism is present along a coast and winds blow its aerosol onshore. A Red Tide Rack Card [PDF 2.36MB] with useful facts and tips about red tide is available.
