State biologists are keeping a close watch on Florida’s coastline this week after finding the first faint traces of the organism that causes red tide.
The latest data from the Florida Fish and Wildlife Conservation Commission (FWC) shows that Karenia brevis is present in the Gulf, though currently only at “background” levels—the lowest possible detectable concentration.
The findings were scattered across the Panhandle and parts of Southwest Florida. In Northwest Florida, single samples from Escambia, Okaloosa, and Gulf counties confirmed the organism’s presence.
Further south, one offshore sample taken near Lee County also showed background traces. Meanwhile, the East Coast remains entirely clear, with no sightings reported over the last seven days.

While the mention of red tide often sparks concern for beachgoers, officials confirmed that there have been no reports of fish kills or the respiratory irritation that typically accompanies a major bloom. The air at the coast remains clear, and no wildlife deaths have been linked to the organism this week.
To stay ahead of any potential shifts, the FWC is teaming up with NOAA and the University of South Florida, using satellite imagery to track water conditions both near the shore and further out at sea.
Short-term forecasts for the next three and a half days suggest that surface waters from Pinellas down to northern Monroe County will likely move toward the south and southwest.
For those planning a weekend at the beach, the current status is purely observational. The state will continue to monitor these low-level concentrations and is scheduled to release an updated status report on Friday, April 24.
