![]() While red tides occur naturally in the Gulf of Mexico, recent studies have shown that human activity is making the problem worse. The algae have an inflammatory effect on fish and other marine life. Karenia Brevis, a particular type of dinoflagellate, is responsible for the toxic blooms in Florida. These substances, known as dinoflagellates, live in lakes, rivers, and estuaries and are abundant in the Gulf. When red tides form in the Gulf of Mexico, algae and other harmful substances build up.

Red tides are caused by industrial agriculture, animal waste, and groundwater runoff. However, it can occur at any time of year and last for several months. In Florida, red tide typically occurs along the Gulf Coast from late summer through early fall. These beaches are affected by this bacterial bloom, which has a long history off the gulf coast. These blooms can produce toxins that can be harmful to people, fish, and other marine life. In 2007, a red-tide bloom near Jacksonville traveled south with a near-shore current.What beaches have red tide in Florida? Red tide is a natural phenomenon that occurs when high concentrations of certain algae bloom in the water. Since 1972 when the transport of red tide from the west coast to the east was first identified, seven more instances had been documented prior to 2018, according to the Florida Fish and Wildlife Conservation Commission. Once in the Gulf Stream, waves can force the toxin produced to be dispersed in the air, which can be carried by east winds to the beaches. A west coast bloom can reach the east coast if it gets caught in the Gulf of Mexico's loop current and travels through the Florida Straits into the Gulf Stream – a north-moving river of warm water that skims the Palm Beach County coastline. Can red tide on Florida's west coast reach the state's east coast? Manatee, Goliath grouper, shorebirds and sea turtles all perished in droves that year in areas from Sarasota through Naples.

Red tide is often gone by spring, but in some years, the infection has lingered. They can grow far offshore in the Gulf and pile up near the coast in the fall and winter as wind patterns blow cold fronts into Florida. They have been observed in the Gulf of Mexico since the 1800s. What is the main cause of red tide and how long does it last? It produces a toxin as a defense mechanism. It is a sea-faring toxic algae, formally known as the single-cell Karenia brevis. In marine life, it’s a killer that affects the nervous system and can cause paralysis. When the toxin from red tide is inhaled, it can cause respiratory symptoms in people, such as coughing, wheezing and sore throats.
