Florida Red Tide Tracker
Current Karenia brevis status along Florida's coastline
Current Status
No Major Red Tide Blooms Reported
As of early March 2026, no significant Karenia brevis blooms have been detected along Florida's coast.
What is Red Tide?
Red tide is a natural phenomenon caused by Karenia brevis, a microscopic algae that produces toxins (brevetoxins) which can be harmful to marine life, birds, and humans. While red tide occurs naturally in the Gulf of Mexico, blooms can be exacerbated by nutrient pollution.
When red tide concentrations are high, the toxins become airborne through wave action and can cause respiratory irritation in people near the shore. Swimming in red tide-affected water can cause skin irritation and is not recommended.
Health Effects & Safety Tips
Respiratory irritation
Coughing, sneezing, and eye/throat irritation near shore. People with asthma or chronic lung conditions are especially sensitive.
Skin irritation
Swimming in water with active red tide can cause rashes and skin irritation. Rinse off immediately if exposure occurs.
Shellfish safety
Do not harvest or eat shellfish from red tide-affected areas. Commercial shellfish are tested and safe to consume.
What To Do During Red Tide
- ➤ Avoid the beach if you can smell or feel respiratory irritation
- ➤ Do not swim in water with dead fish or discolored water
- ➤ People with asthma should stay away from affected beaches
- ➤ If you experience symptoms, move away from the beach to air-conditioned space
- ➤ Check FWC's daily red tide sample map before heading to the beach
