Questions about Moon Palace Nizuc

Yes, in season. At Moon Palace Nizuc the typical-year risk is moderate or higher from February to September and peaks in July (high). How much lands varies a lot by year, wind and currents.

What are the worst and best months for seaweed at Moon Palace Nizuc?

Does Moon Palace Nizuc have a sargassum barrier or beach cleanup?

Veabird doesn't track barriers hotel by hotel; this is what the Cancún & Isla Mujeres area does. Offshore barriers in Cancún & Isla Mujeres: floating sargassum barriers deployed by Mexican Navy (SEMAR) and state along exposed Caribbean stretches; north Gulf-facing shore rarely needs them. Resort crews: Large resorts run their own barrier/rake crews at dawn. Typical clearing time: same-day.

The Atlantic hurricane season runs June through November and peaks around September. A tropical storm passed within 86 miles of Moon Palace Nizuc in 20 of the 55 seasons from 1971 to 2025, and a hurricane within 58 miles in 4. The riskiest stretch is around September 17, when the chance of a storm passing in any one week is about 3%; across all of September it is about 12%.

Sargassum season at Moon Palace Nizuc

Sargassum risk at Moon Palace Nizuc 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 105°; 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.
