Sargassum season at The San Luis Resort
Sargassum is rare at The San Luis Resort: Veabird estimates moderate or heavier seaweed on the beach in fewer than one week in ten in every month.
Estimated share of weeks in each month with moderate or heavier seaweed on the beach. Veabird takes the landing season seen on Quintana Roo's beaches (a Puerto Morelos beach camera, 2015–2020, and the Mexican Navy's beach alerts, 2022–2026), the nearest coast with a multi-year beach record (this one has none), and scales it by how often NOAA AOML satellites see notable seaweed within about 20 km of this stretch of coast: 4% of weeks here on average, against 54% off Quintana Roo, so 8% of that season. The satellite share (2016–2024, the top fifth of all coast-weeks, adjusted for this beach's exposure of 70%) 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 140°; 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.
