According to FWC:

Current Conditions The red tide organism, Karenia brevis, persists in Southwest Florida. Bloom concentrations were detected in Charlotte County only, where “medium” K. brevisconcentrations were observed. Additional details are provided below.

  • In Southwest Florida over the past week, K. brevis was observed at background concentrations in Manatee County, background to medium concentrations in Charlotte County, background to low concentrations in Lee County, and background concentrations in Collier County.
  • 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 were reported in Charlotte County. More detailed information is available at

Respiratory irritation was reported over the past week in Manatee, Sarasota, Charlotte, and Lee counties. 

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

A midweek status update will be available on Wednesday, February 6th and the next complete status report will be issued on Friday, February 8th. Please check our daily sampling map, which can be accessed via the online status report on our Red Tide Current Status page.

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.
