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.
