Florida: Red Tide Concentrations Drop in SW Florida, Absent in Rest of State

Current Conditions The red tide organism, Karenia brevis, persists in Southwest Florida. Bloom concentrations (>100,000 cells per liter) were detected only offshore of Monroe County. Additional details are provided below.

  • In Southwest Florida over the past week, K. breviswas observed at background concentrations offshore of Charlotte County, background concentrations offshore of Lee County, low concentrations in Collier County, and background to medium concentrations offshore of Monroe County.
  • In Northwest Florida over the past week, K. breviswas not observed.
  • Along the Florida East Coast over the past week,K. brevis was not observed.

No fish kills suspected to be related to red tide were reported this week (please see https://myfwc.com/research/saltwater/health/fish-kills-hotline).

Respiratory irritation was reported over the past week in Manatee and Lee counties. Additional details are provided in the Southwest Coast report.

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

A midweek status update will be available on Wednesday, February 13th and the next complete status report will be issued on Friday, February 15th. 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.
