Sargassum season at Caye Caulker Beach Resorts
Low sargassum risk year-round at Caye Caulker Beach Resorts: even around July, the usual peak, Veabird estimates moderate or heavier seaweed on the beach in about 15% of weeks. 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: 12% of weeks here on average, against 54% off Quintana Roo, so 23% of that season. The satellite share (2016–2024, the top fifth of all coast-weeks, adjusted for this beach's exposure of 60%) 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 90°; 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.

Cleanup & barriers
- Offshore barriers
- Few booms; the Belize Barrier Reef breaks up but does not stop mats reaching caye shores.
- Public cleanup
- Village councils and Sargassum Task Force crews rake public beaches on Ambergris and Caye Caulker during heavy years.
- Resort crews
- Upscale resorts rake frontage daily; smaller properties rely on hand crews.
- Typical clearing time
- Frontage usually cleared by mid-morning; shallow backreef water can stay tea-colored for days.
Safety notes
US State Dept: Belize, Level 2 (verify)
- Petty theft and crime concentrated in Belize City; cayes and Placencia generally calmer
- Use licensed guides for reef and dive trips; check boat safety gear
- Golf carts are the main transport on Ambergris; roads unlit at night
Check official advisories and local flags before swimming. Decomposing sargassum releases hydrogen sulfide; avoid heavy piles.
