Red Tide Report: 9/1/23


Red tide was not detected in samples collected from offshore Florida over the past week. All samples, except for two collected on 08/31 in Sarasota Bay, were collected prior to the passage of Hurricane Idalia. Sampling has since resumed and results will be posted on the FWC Red Tide Daily Sample Map (https://myfwc.com/redtidemap) once available.

No fish kills suspected to be related to red tide were received over the past week. For more details, please visit https://myfwc.com/research/saltwater/health/ and https://visitbeaches.org/.

Respiratory irritation suspected to be related to red tide was not reported in Florida over the past week. For recent and current information at individual beaches, please visit https://visitbeaches.org/ and for forecasts that use FWC and partner data, please visit https://habforecast.gcoos.org/.

Forecasts by the USF-FWC Collaboration for Prediction of Red Tides for Pinellas County to northern Monroe County predict variable transport of surface and subsurface waters in most areas over the next 3.5 days.

The next status report will be issued on Friday, September 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.
