Current Conditions
The red tide organism, Karenia brevis, was detected in 72 samples collected from and offshore of Southwest Florida over the past week. Bloom concentrations (>100,000 cells/liter) were present in 16 samples: one offshore of Pinellas County, seven in Manatee County, two in Sarasota County, two offshore of Charlotte County, two offshore of Collier County, and two offshore of Monroe County. Additional details are provided below.

In Southwest Florida over the past week, K. brevis was observed at background to medium concentrations in and offshore of Pinellas County, background concentrations in Hillsborough County, background to medium concentrations in Manatee County, background to medium concentrations in Sarasota County, low to medium concentrations in and offshore of Charlotte County, background concentrations in Lee County, background to high concentrations offshore of Collier County, and medium concentrations offshore of Monroe 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.

Reports of fish kills suspected to be related to red tide were received in Southwest Florida from Pinellas, Manatee, Sarasota, Charlotte, and Collier counties over the past week. For more details, please visit https://myfwc.com/research/saltwater/health/fish-kills-hotline/ and https://visitbeaches.org/.

Respiratory irritation suspected to be related to red tide was reported via the Beach Conditions Reporting System and/or the Fish Kill Hotline over the past week in Southwest Florida in Pinellas County (Boca Ciega Bay, Indian Shores Beach), Manatee County (Anna Maria Beach, Anna Maria Island Rod and Reel Pier, Anna Maria Public Beach, Coquina Beach, Longboat Key Beach, Manatee Beach, Pine Avenue Canal), Sarasota County (Blind Pass Beach, Lido Key Beach, Longboat Key, Manasota Key Beach, Manasota North Beach, Nokomis Beach, Siesta Key Beach, Snake Island, South Lido Key Beach, Stump Pass Park, Turtle Beach, Venice Beach, Venice North Jetty Beach), and Charlotte County (Manasota Key Beach). 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 net southern movement of surface waters and southeastern transport of subsurface waters in most areas over the next 3.5 days.

The next status report will be issued on Friday, January 13^th. 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.
