Is the area having seaweed issues!

Hi - headed to AMI next week. Does AMI and the surrounding beaches have seaweed issues right now? We have been through red tide in Siesta Key a couple of years ago. Is this similar?

Good question! Short answer: yes — Anna Maria Island (AMI) has seen red tide issues recently, which is different from the typical “seaweed blob” (sargassum) concern. Here’s a detailed breakdown of what you should know for your trip next week:

Current Conditions on Anna Maria Island

  • There is an active red tide health alert in some parts of AMI, according to the Florida Department of Health.
  • The red tide organism, *Karenia brevis*, was detected in samples along the gulf waters near Manatee County.
  • The county (Manatee) performs beach sweeps to remove seaweed, dead fish, and debris associated with red tide.

Seaweed (Sargassum) vs. Red Tide — What’s the Difference?

  • Sargassum: This is floating seaweed that sometimes washes ashore (“seaweed blob”), but is not the same as red tide. Historically, AMI has had some sargassum, especially after certain winds.
  • Red Tide: Caused by a microscopic alga (*Karenia brevis*) that can be harmful — it can irritate skin and eyes, cause respiratory symptoms, and sometimes leads to dead fish washing ashore.
  • Recent reports lean toward red tide concerns, rather than a massive sargassum blob.

How It Compares to What You Experienced at Siesta Key

If you went through a red tide event in Siesta Key, the situation on AMI could feel somewhat similar — since the current alert is also for red tide. But it’s not exactly the same as a big floating seaweed mass (sargassum). The main risk now on AMI seems to be related to microscopic algae, not giant clumps of seaweed.

What to Know for Your Trip

  • Check daily beach-condition updates: The Florida Fish & Wildlife Commission (FWC) and local Manatee County or AMI resources provide real-time sampling data.
  • If you go to the water and start to feel eye or throat irritation, coughing, or other respiratory symptoms, it could be due to red tide — rinse off, and consider avoiding swimming in that area until conditions improve.
  • Avoid “dead fish” areas: If you happen to see dead fish washed up, steer clear — red tide is often tied to fish kills, and contact can worsen symptoms.
  • For the most updated alerts, check the FWC Red Tide Current Status page or local AMI beach-condition resources.

Bottom Line: Yes, there is red tide activity in and around Anna Maria Island currently, which carries potential risks (respiratory, skin, irritation). It’s not exactly a giant sargassum seaweed blob scenario — more of a microscopic algae issue. If you're sensitive (or have respiratory issues), keeping an eye on conditions when you’re there is a smart move.
