Red Tide Florida Report
Weekly Red Tide Map: Dots on the map below show tested concentrations of red tide blooms in the Gulf of Mexico and inland waters, released on 2/1/2023 by Florida Fish and Wildlife.
Red Tide Report Details
Wednesday, Feb. 1 — The red tide organism, Karenia brevis, was detected in 54 samples collected from and offshore of Southwest Florida over the past week.
Bloom concentrations (>100,000 cells/liter) were present in 12 samples: one in Sarasota County, 10 in Lee County, and one in Monroe County.
- In Southwest Florida over the past week, K. brevis was observed at very low concentrations in Pinellas County, background to low concentrations in Manatee County, background to medium concentrations in Sarasota County, low concentrations in Charlotte County, very low to high concentrations in Lee County, very low concentrations offshore of Collier County, and background to high concentrations in and 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 Sarasota County over the past week. For details, visit: https://myfwc.com/research/saltwater/health/fish-kills-hotline/ and https://visitbeaches.org/.
Respiratory Irritation due to red tide
Respiratory irritation suspected to be related to red tide was reported via the Beach Conditions Reporting System over the past week in Southwest Florida in Manatee County (Coquina Beach and Manatee Beach) and Sarasota County (Lido Key Beach, Manasota Key Beach, Nokomis Beach, Siesta Key Beach, Venice Beach, Venice North Jetty Beach).
Red tides form many miles offshore, sometimes causing no impact to humans. However, when red tides travel inshore on wind and water currents, they can cause respiratory irritation among beachgoers, especially those who have underlying lung diseases, such as asthma or COPD.
Red tide movement forecast
Forecasts by the USF-FWC Collaboration for Prediction of Red Tides for Pinellas County to northern Monroe County predict variable movement of surface and subsurface waters with minimal net transport in most areas through Sunday, Feb. 5.
Daily Beach Condition reports reflect observations on beaches throughout the state.
