Red tide? Dodge it. Watch a Video.

  Oct 04 - Dec 31, 2018


Don't wade, swim or swallow water where there is red tide.

In Florida, red tide is caused by a naturally occurring microscopic alga (a plant-like microorganism) called Karenia brevis or K. brevis.

Red tides occur all over the world

No single factor causes a red tide. K. brevis is found almost exclusively in the Gulf of Mexico but has been found on the east coast of Florida and of the coast of North Carolina.
