Red Tide Today in Palm Harbor

The cards above show the most recent FWC water samples near Palm Harbor Gulf beaches. Green means no red tide was found in the latest nearby sample; amber or red means low-to-high concentrations were detected. Sampling is periodic and conditions change quickly, so always confirm before you go.

Honeymoon Island, Caladesi Island, Crystal Beach, Dunedin Causeway, Clearwater Beach, and Sunset Beach in Tarpon Springs. Each shows the most severe FWC sample found within about 8 km over the last 8 days.

Red tide can cause respiratory irritation and make some seafood unsafe. During an active bloom, sensitive groups should avoid the beach and everyone should limit exposure. Check the status above and any posted advisories before swimming.

Red tide on Florida's Gulf coast is a harmful algal bloom of the organism Karenia brevis. In high concentrations it discolors water, kills fish, and releases toxins that cause coughing and eye irritation along the shore.

The readout pulls live from FWC's water-sample feed and reflects the latest published samples, typically updated a few times per week during active conditions. It is a recent-sample guide, not a real-time water monitor.
