Resort crews: Large resorts run their own barrier/rake crews at dawn. Typical clearing time: same-day.

Sargassum season at Iberostar Selection Cancún
Sargassum risk at Iberostar Selection Cancún typically peaks around July (high: moderate or heavier seaweed on the beach in an estimated 66% of weeks). Months most likely to see heavy seaweed: May, June and July. Lowest-risk months: January, 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 seen on Quintana Roo's beaches (a Puerto Morelos beach camera, 2015–2020, and the Mexican Navy's beach alerts, 2022–2026) and scales it by how often NOAA AOML satellites see notable seaweed within about 20 km of this stretch of coast: 56% of weeks here on average, against 54% off Quintana Roo, so the full season applies. The satellite share (2016–2024, the top fifth of all coast-weeks, adjusted for this beach's exposure of 95%) 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 95°; 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.
