Sargassum costs Mexican Caribbean hotels up to 30 million a year

Every sargassum season costs the hotel sector in the Mexican Caribbean between 20 and 30 million dollars, according to figures reported by Hosteltur. That money goes into containing the seaweed, clearing it from the shore and slowing beach erosion, which is the asset that keeps the whole operation running.

Put it in business terms. 30 million a year spread across the hotel plant in Cancun, the Riviera Maya and Tulum is not just another maintenance line. It eats straight into margin, with no linked revenue, and it grows with the intensity of the phenomenon. In peak arrival season the outlay is concentrated into a few weeks and forces hotels to move crews, machinery and barriers against the clock. My take: anyone budgeting sargassum as a seasonal surprise is getting it wrong. It is becoming a fixed line, like energy or payroll.

The interesting part is where the opportunity sits. Hotels already working with more efficient barriers, selective mechanical collection and, above all, erosion prevention are measuring every dollar. That is the edge: not spending less, but spending better and documenting the impact to justify rates and protect the beach promise.
