Is there red tide in Florida every year?
Florida’s Red Tide was around long before humans and industry populated the coast. Karenia brevis blooms occur in the Gulf of Mexico almost every year, generally in late summer or early fall. They are most common on the central and southwestern coasts of Florida between Clearwater and Sanibel Island but may occur anywhere in the Gulf.
How do red tide blooms occur?
The runoff from these various processes dissolves into the land's water, makes its way towards the ocean from rivers and streams, and causes red tide blooms the unnatural way. Red tides can last a few weeks, or in some cases, remain visible for over a year.

How often does red tide happen?

Is red tide annual?
Red tide is an annual algal bloom where the overgrowth of karenia brevis in a body of water produces toxins that kill marine life. It can even make it difficult for humans to breathe. This year's bloom started off the coast of southern Florida in December 2020, working its way up to St Petersburg by April.

For most people, symptoms are temporary when red tide toxins are in the air.

Fewer toxins are in the air when the wind is blowing offshore.

Where are red tide occurrences found?
Within the United States, red tides occur most commonly in the Gulf of Mexico, off California, and in the Gulf of Maine. In each of these locales, a different microorganism—present at low levels normally—generates the algal bloom when conditions align.
Can red tide make you sick?
For beachgoers, coastal residents and others exposed to Karenia brevis (K. brevis) algal blooms, the red tide's toxins can irritate the eyes, nose, throat and respiratory system. Symptoms can be pronounced in those with underlying chronic respiratory conditions, including asthma, emphysema and COPD.
Does red tide go away in winter?
Even though the toxic algae blooms have dissipated, for now, Dr. Weisberg says there's still a chance for them to return over the next few months. He says a typical red tide season is from October to December but that can fluctuate annually.
How long does red tide last?
How long does a red tide last? Red tide blooms can last days, weeks or months, and can also change daily due to wind conditions and ocean currents.
What months does red tide occur in Florida?
Red tide occurs naturally in coastal waters of the Gulf of Mexico with blooms appearing seasonally. Although the Florida red tide organism, Karenia brevis, typically blooms between August and December, blooms often deviate from that time frame.

What causes red tides?
The red tide is a phenomenon that is caused by algae. While it might look like someone has tipped a lot of red dye into the sea, this discoloration is actually caused by millions of algae gathering under the sea. These groups of algae are known as algal blooms, and they are very common during the warmer, summer months.
Why are red tides dangerous?
This is because the red tide itself is caused by a gathering of harmful algae which form into something known as a bloom. These harmful algae can then release toxins into the water, which affect marine life, as well as mammals, birds, and even humans.
