Just as locals and tourists prepare for the holiday weekend, state environmental officials have confirmed the return of red tide to Northwest Florida, with bloom concentrations detected in Bay County.
Over the past week, the Florida Fish and Wildlife Conservation Commission (FWC) identified the red tide organism, Karenia brevis, in eight different samples collected across the region.
While the presence was noted in multiple areas, one specific sample in Bay County showed “bloom concentrations,” meaning levels exceeded 100,000 cells per liter.
The bloom is already impacting local wildlife and beachgoers. The FWC’s Fish Kill Hotline has received reports of dead fish suspected to be caused by the toxin in both Bay and Gulf counties.

Additionally, people in Bay County have reported experiencing respiratory irritation—a common side effect of the airborne toxins released by the algae, which can cause coughing and throat scratchiness, particularly for those with asthma.
Tracking the exact scope of the bloom has proven difficult in recent days. While researchers from the University of South Florida (USF) and NOAA usually rely on satellite imagery to monitor conditions, heavy cloud cover has obscured views of the coastline.
Looking ahead, forecasts from the USF-FWC collaboration predict that surface and subsurface waters will move south to southeast over the next three and a half days, potentially shifting the bloom along the coast.
Due to the upcoming holidays, the FWC noted that this is the final update for the year. The next status report is scheduled for release on Friday, January 9.
