Current Conditions
The red tide organism, Karenia brevis, was observed at background concentrations in Southwest Florida and Northwest Florida over the past week. Additional details are provided below.

  • In Southwest Florida over the past week, K. brevis was observed at background concentrations in one sample collected offshore of Hillsborough County and one sample collected from Sarasota County.
  • In Northwest Florida over the past week, K. brevis was observed at background concentrations in one sample collected from Bay County.
  • 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 over the past week (please see https://myfwc.com/research/saltwater/health/fish-kills-hotline).

No respiratory irritation suspected to be related to red tide was reported over the past week.

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

The next complete status report will be issued on Friday, April 12th. Please check our daily sampling map, which can be accessed via the online status report on our Red Tide Current Statuspage.

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.
