Sargassum season at Mount Cinnamon
Sargassum risk at Mount Cinnamon typically peaks around July (moderate: moderate or heavier seaweed on the beach in an estimated 30% of weeks). Lowest-risk months: January, February, March, April, May, August, September, October, November and December. Actual landings vary a lot by year, wind and currents; check the live conditions above.
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: 9% of weeks here on average, against 14% off Martinique, so 67% of that season. The satellite share (2016–2024, the top fifth of all coast-weeks, adjusted for this beach's exposure of 18%) 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 9°; onshore winds from that direction push seaweed ashore. The satellite record as open data.
