Red Tide Returns to Florida’s Lee, Collier Counties

A patchy bloom of the red tide organism, Karenia brevis, persists in Southwest Florida. K. brevis was detected in 39 samples over the past week, with bloom concentrations (>100,000 cells/liter) observed in 26 of those collected from Lee and Collier counties. Additional details are provided below.

  • In Southwest Florida over the past week, K. brevis was observed at background concentrations in Sarasota County, very low to high concentrations in Lee County, and medium to high concentrations in and offshore of Collier County. K. brevis was not detected in samples from Pinellas, Manatee, Charlotte, and Monroe counties.
  • In Northwest Florida over the past week, K. brevis was not observed.
  • Along the Florida East Coast over the past week, K. brevis was not observed.

In Southwest Florida over the past week, fish kills suspected to be related to red tide were reported in Lee and Collier counties. For more details, please visit:

Respiratory irritation was reported over the past week in Southwest Florida in Lee and Collier counties. For current conditions, please visit:

Forecasts by the USF-FWC Collaboration for Prediction of Red Tides for Pinellas to northern Monroe counties predict net southeastern transport of surface and subsurface waters in most areas over the next four days.

The next complete status report will be issued on Friday, January 22nd. Please check our daily sampling map, which can be accessed via the online status report on our Red Tide Current Status page. For more information on algal blooms and water quality, please visit Protecting Florida Together.

This information, including maps and reports with additional details, is also available on the FWRI Red Tide website. The website also provides links to additional information related to the topic of Florida red tide including satellite imagery, experimental red tide forecasts, shellfish harvesting areas, the FWC Fish Kill Hotline, the Florida Poison Information Center (to report human health effects related to exposure to red tide), and other wildlife related hotlines.
