Some beaches along the Southwest Florida Gulf Coast may experience moderate to high levels of respiratory irritation over the weekend due to red tide, according to environmental officials.
The National Center for Coastal Ocean Science reported that elevated concentrations of Karenia brevis, the organism responsible for red tide, have been detected in the waters off Collier and Lee counties.
Onshore winds could increase the risk of respiratory issues, particularly along beaches from Sanibel to Naples Pier.
Red tide can cause symptoms such as coughing, sneezing and throat irritation, especially for individuals with respiratory conditions. Health officials advise beachgoers to check conditions before visiting the shore and to avoid areas where irritation is reported.
The likelihood of experiencing symptoms depends on wind direction, officials said. Onshore or alongshore winds increase the risk, while offshore winds reduce exposure.
