Sargassum in Fort Lauderdale & Sunny Isles Today
Updated June 29, 2026 from Copernicus satellite data — refreshed 4× per day.
Is there sargassum in Fort Lauderdale today? Check the live status panel above: Fort Lauderdale Beach shows its current status today — clean, moderate or avoid — read straight from the latest satellite pass and updated today. Sunny Isles, just south, almost always tracks the same southeast-Atlantic pattern, so the map gives you a same-day read for both before you load the car. Most seaweed pages quote a monthly average; this one measures your sand. We pull Copernicus and NOAA AFAI imagery four times a day, score each beach 0–100, and project a per-beach 7-day forecast — measured, never guessed. When clouds block a satellite pass, the page says so and shows the data age and a confidence level rather than pretending. Beachgoer reports fill the gaps. In peak summer the coast can flip overnight on an east wind, so the honest answer is always the live one: check the Beach Score the morning you go, not last week's bulletin.
Fort Lauderdale or Sunny Isles — which is cleaner today?
Both sit on the open Atlantic in the Miami–Palm Beach corridor, so in season they take the same episodic sargassum pulses. They are not identical, though: a wind shift or a Gulf Stream wobble can leave one raked clean while the other holds a fresh wrack line. That is exactly why a regional bulletin fails you and a per-beach read wins. The panel above ranks Fort Lauderdale Beach by today's Beach Score; for Sunny Isles, the nearest tracked points on either side bracket its likely status. Fort Lauderdale runs regular municipal raking, which resets the sand fast — but if satellites show fresh mats inbound, seaweed can return within hours. Check both before you commit, and keep a backup in mind.
When does it clear, and is the smell a safety issue?
Beached sargassum decays on roughly a 3.5-day half-life unless new mats keep landing, so a buried morning can be clean sand within days — faster where crews rake daily. Our 7-day forecast shows whether fresh material is inbound or the coast is set to clear; days 1–3 carry the most confidence, days 4–7 show direction of travel. On safety: small amounts in the water are harmless to swimmers. Large rotting piles release hydrogen sulfide (H2S) — the rotten-egg smell — which can irritate eyes, throat and lungs, and bothers people with asthma most. Avoid sitting downwind of thick, decaying wrack lines, and keep kids and pets off big piles. When a beach reads avoid, the smell is usually the reason.
Where to go instead when both are buried
South Florida gives you options, and the live map shows the nearest clean sand instantly. If Fort Lauderdale and Sunny Isles both read avoid, the central Atlantic coast — Cocoa Beach, Daytona — sits north of the heaviest sargassum highway and is often far lighter. The reliable fallback is the Gulf coast: Clearwater almost never sees meaningful sargassum even in peak weeks. It is a longer drive but a near-certain win. Within easy reach, Palm Beach and Jupiter sometimes reset faster because the Gulf Stream runs close and sweeps mats away quickly. Pull up the full Florida list, sort by Beach Score, and pick the closest clean option rather than gambling on a single beach.
Frequently asked questions
Is there seaweed in Sunny Isles Beach today?
Check the live panel above for today's status. Sunny Isles sits on the open Atlantic between Miami Beach and Fort Lauderdale, so it tracks the same southeast-Florida pattern, read four times a day from satellite. In peak summer it can flip overnight on an east wind, so the only reliable answer is the same-day one — not a seasonal average.
Does Fort Lauderdale Beach get raked of sargassum?
Yes. Fort Lauderdale runs regular municipal beach cleaning that resets the sand quickly, usually in the morning. But raking only clears what has already landed — if satellites show fresh mats drifting in, seaweed can return within hours. Pairing the cleaning schedule with today's satellite forecast tells you more than either alone.
Is sargassum dangerous to swim near in Fort Lauderdale?
Small amounts floating in the water are harmless to swimmers. The real concern is large rotting piles on the sand, which release hydrogen sulfide (H2S) — a rotten-egg smell that can irritate eyes, throat and lungs, especially for people with asthma. Stay upwind of thick, decaying wrack lines and keep kids and pets off big piles.
How accurate is this Fort Lauderdale sargassum tracker?
It uses the AFAI satellite index from Copernicus and NOAA — the same data NOAA relies on — refreshed four times a day. Floating mats have a distinct spectral signature satellites detect reliably in clear weather; clouds can delay a reading, so every beach shows its data age and a confidence level. It is a measurement, not a guess.
When is sargassum worst in Fort Lauderdale?
Roughly May through August, peaking in June and July, in line with the broader Atlantic bloom. Winter through early spring is effectively seaweed-free. Even in peak season the landings are episodic — a beach can be buried one day and raked clean a few days later — which is why the daily satellite read matters more than the calendar.
