A real satellite tally: 16 days of Copernicus / NOAA measurements across Florida beaches in August 2026. No estimates — only what the satellite actually observed.
Satellite measurements from August 16 to August 31 — 16 days observed.
98% of the month’s 320 beach-day measurements were clean.
A day counts as “100% clean” when every beach measured that day is clean (AFAI index < 0.15). A single moderate (0.15–0.40) or avoid (> 0.40) beach downgrades the day.
Ranking computed from the month’s real measurements: share of clean days, then mean AFAI index (lower = less sargassum).
The monthly tally says what happened. The map says where to go today.
