Press & media — Florida sargassum data
Updated June 22, 2026 from Copernicus satellite data — refreshed 4× per day.
The Atlantic is having a widely reported record sargassum season. What the headlines rarely answer is the question your readers actually ask: is my beach swimmable today? We publish that answer for Florida, beach by beach, from satellite data — and it is free to cite with attribution.
What we publish
Live sargassum status for 12 Florida beaches — from the Keys (Key West, Marathon, Islamorada, Key Largo) up the southeast Atlantic coast (Miami Beach, Fort Lauderdale, Palm Beach, Jupiter) and across to the Gulf at Clearwater — each with a clean / moderate / avoid rating, a 0–100 Beach Score and a beach-specific 7-day forecast. Detection uses the AFAI (Alternative Floating Algae Index) from the Copernicus and NOAA satellite programs, sampled pixel by pixel directly offshore of each beach — not a regional average — and refreshed four times a day, with wind and swell data from Open-Meteo. As of June 22, 2026, 12 of 12 tracked beaches read clean.
Accuracy, published openly
We backtest the forecast against what satellites later observed, and we publish the results: across our network, next-day beach status verifies 76% of the time, and 3-day status 72%. Days 1–3 are the most reliable; days 4–7 show the trend — and we say so on every page. The data is never hand-edited, never filtered for resorts, never deleted.
