On February 19, the Florida Department of Health in Lee County (DOH-Lee) officially lifted the health alerts previously issued on December 13, January 23, January 29, February 4, and February 5 for red tide presence near several Sanibel locations, including:
- Bowman’s Beach
- Bowman’s Beach (9.5 miles southwest of the mainland)
- Tarpon Bay Road Beach (1 mile south of the mainland)
- Tarpon Bay Road Beach (5.1 miles southwest of the mainland)
- Tarpon Bay Road Beach (9 miles southwest of the mainland)
Recent water samples collected by the Florida Fish and Wildlife Conservation Commission (FWC) confirmed that red tide levels in these areas have either dissipated or returned to background levels, making it safe for the public to resume water-related activities.
Stay Cautious: Red Tide Conditions Can Change
While this is welcome news, DOH-Lee advises residents and visitors to remain cautious, as red tide conditions can change depending on environmental factors. If you experience eye or respiratory irritation, it’s best to leave the area or seek relief indoors in an air-conditioned space.

What is Red Tide?
Red tide is caused by high concentrations of Karenia brevis (K. brevis), a microscopic algae naturally found in the Gulf of Mexico. Under certain conditions, this algae can multiply rapidly and discolor the water, often giving it a red or brown hue.
Red tide blooms typically form offshore in late summer or early fall and move toward the coast due to wind and currents. Learn more here:
Red Tide Information
Is Red Tide Harmful?
Yes. K. brevis produces brevetoxins, which can harm humans, pets, marine life, and wildlife.
Potential Health Effects:
- Airborne toxins can cause respiratory irritation (coughing, sneezing, throat irritation).
- Direct skin contact may lead to itchiness or rashes.
- Sensitive individuals (children, the elderly, those with respiratory issues) may experience more severe symptoms.
