Estimated share of weeks in each month with moderate or heavier seaweed on the beach. Veabird takes the landing season measured on Martinique's shores (Madininair's hydrogen-sulfide sensors beside stranding sites, 2018–2026) and scales it by how often NOAA AOML satellites see notable seaweed within about 20 km of this stretch of coast: 27% of weeks here on average, against 14% off Martinique, so the full season applies. The satellite share (2016–2024, the top fifth of all coast-weeks, adjusted for this beach's exposure of 90%) measures seaweed offshore, not on the sand: off the Riviera Maya it reads high even in winter, when little lands. Very low under 10%, Low 10–24%, Moderate 25–44%, High 45–69%, Very high 70%+. Beach faces 90°; onshore winds from that direction push seaweed ashore. Satellite sargassum data: USF Optical Oceanography Lab (Sargassum Watch System) via NOAA AOML. The satellite record as open data.
