What this means on the sand

Sargassum is a floating brown seaweed that drifts ashore from the Atlantic in pulses, heaviest from roughly May through August. Light levels mean scattered clumps you can walk around; heavy levels mean thick mats along the waterline, a sulfur smell as it breaks down, and tougher entry into the water.

On the Gulf coast this page also tracks red tide (Karenia brevis) from FWC sampling. Elevated red tide can mean respiratory irritation on the beach and dead fish in the surf; on high days, the score reflects it and this report names it.

ShoreScore folds this reading into Tigertail Beach (Marco Island)'s overall 0-100 score alongside live weather, surf, UV, and official water-quality testing, so one number tells you whether it's worth the trip.
