Key Largo Sargassum Today — Live Status & 7-Day Forecast

Status today: Clean · Beach Score 88/100
The diving capital — John Pennekamp's reefs are the real draw, with small man-made beaches as a bonus rather than the main event. Ocean-side spots collect seaweed in season; the protected snorkeling lagoons matter more here than sand quality. Pair a map check with your dive booking.
