Does Hotel Long Beach have a sargassum barrier or beach cleanup?
Veabird doesn't track barriers hotel by hotel; this is what the Honduras & Bay Islands area does. Offshore barriers in Honduras & Bay Islands: no barriers; fringing reef diverts some mats. Resort crews: West Bay and north-shore resorts rake mornings. Typical clearing time: West Bay rarely affected; east/north shores cleared within a day or two.
When is hurricane season at Hotel Long Beach, and how often do storms hit?
The Atlantic hurricane season runs June through November and peaks around September. A tropical storm passed within 86 miles of Hotel Long Beach in 15 of the 55 seasons from 1971 to 2025, and a hurricane within 58 miles in 4. The riskiest stretch is around October 15, when the chance of a storm passing in any one week is about 2%; across all of October it is about 9%. Flexible bookings and travel insurance help in the peak weeks.
Sargassum season at Hotel Long Beach
Sargassum risk at Hotel Long Beach typically peaks around July (moderate: moderate or heavier seaweed on the beach in an estimated 33% 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 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: 27% of weeks here on average, against 54% off Quintana Roo, so 51% of that season. The satellite share (2016–2024, the top fifth of all coast-weeks, adjusted for this beach's exposure of 33%) 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 306°; 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.
