Yes — Cancún has some of the most aggressive daily cleanup operations in the Riviera Maya. Resorts employ crews before dawn to clear their beach sections. Public beaches like Playa Delfines are cleaned by municipal crews. Even so, open-ocean conditions mean heavy surges can overwhelm cleanup efforts temporarily.
Yes, decomposing sargassum releases hydrogen sulfide gas — a rotten egg smell. Fresh sargassum floating offshore has minimal odor. The smell intensifies when large mats decompose onshore, typically within 24–48 hours of beaching. It's strongest on windless days and in sheltered areas where it accumulates.
