Let’s take a closer look at the phenomenon of red tide and explain how to stay safe when you visit Anna Maria Island’s beaches.
Current Conditions of Red Tide, Anna Maria Island
Red Tide on Anna Maria Island is a fairly uncommon phenomenon. It’s essential to check current conditions on the beaches before you go swimming, but it’s unlikely that you’ll find yourself unknowingly exposed to red tide.
Signage and flags at the beaches highlight unsafe swimming conditions in the event that red tide blooms are present or forecast. As long as there are no warnings, you are free to visit the beach without fear of red tide.
What is Red Tide?
Red tide refers to a harmful algal bloom, most commonly caused along Florida’s Gulf Coast by a microscopic organism called Karenia brevis.
When present in high concentrations, these algae can color the water reddish or brownish (hence “red tide”) and produce toxins known as brevetoxins. These toxins can harm marine life and trigger respiratory irritation in humans when wave action releases them into the air.
Fortunately, it's easy to test for red tide conditions, and the government of Florida provides sampling details to all surrounding areas.
Potential Risks of Red Tide
- Marine life impacts: Fish, shellfish, sea turtles, dolphins, and manatees can be poisoned or suffocated by altered oxygen levels or toxins.
- Human health: Respiratory irritation symptoms, such as coughing, sneezing, wheezing, sore eyes, and sore throat, are common when the red tide is active. People with asthma or chronic bronchial conditions are especially vulnerable to red tide and its respiratory irritation.
- Skin & eye irritation: Some swimmers report rashes or burning eyes after exposure.
- Shellfish risk: Shellfish (like clams or oysters) harvested in red tide-affected waters can concentrate toxins and become unsafe to eat.
History of Red Tide on Anna Maria Island
Anna Maria Island, part of Florida’s Gulf Coast, has been periodically affected by red tide outbreaks, most notably in 2015 and 2018.
In early 2025, red tide algal blooms were detected at various locations off the coast of Southwest Florida and briefly limited safe use of the beaches in Anna Maria Island. The blooms have since dissipated.
Over the years, Manatee County and local agencies have conducted regular monitoring and issued public advisories to control harmful algal blooms and mitigate associated risks.
How to Check Beach Conditions in Manatee County
Fortunately, you can check the most up-to-date red tide status on the Gulf Coast via the Manatee County Safe Beach website. Via this site, the Florida Department of Fish and Wildlife keeps the public informed about potentially hazardous beach conditions throughout the state. The website is updated daily.
You can also check the Fish and Wildlife Service website to view the presence of algae in the water over the last eight days. Individual dots on the map represent levels of algae in the water based on the latest water samples
