Red Tide Current Status
Red Tide Status Update for March 1, 2024
The red tide organism, Karenia brevis, was not observed in samples collected statewide over the past week. We continue to use satellite imagery (USF and NOAA NCCOS) to help track nearshore and offshore conditions. For additional information please view:
Respiratory irritation 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://coastalscience.noaa.gov/science-areas/habs/hab-forecasts/gulf-of-mexico/.
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 over the next 3.5 days.
