Red Tide Facts vs. Myth

Watch and share this invaluable video from Collier County Pollution Control, which contains factual information about red tide.


Our beach areas are experiencing medium to high concentrations of red tide and following is information you should be aware of, especially if you have respiratory issues: Florida Red Tide and other Harmful Algal Blooms (HABs) Facebook page

Red tide is a naturally-occurring microscopic alga that has been documented along Florida’s Gulf Coast since the 1840’s.

Blooms, or higher-than-normal concentrations, of the Florida red tide alga, Karenia brevis, begin in the Gulf of Mexico 10 to 40 miles offshore and can be transported inshore by winds and currents. Blooms occur nearly every year.

A bloom of K. brevis has been ongoing in southwest Florida since November 2017 and FWC has received numerous fish kill reports from Sarasota to Collier counties. We continue to work with numerous local, state, regional, and federal partners to monitor this event and associated impacts.
