Sargassum is no longer a Cancun problem: it's national

Sargassum is no longer a seasonal nuisance. According to Dominican Today, the massive arrival of this seaweed is significantly dropping tourist numbers in Cancun and the Riviera Maya, a destination competing head-to-head with Punta CanaPunta CanaThe main tourism hub of the Dominican Republic, on the eastern tip, famous for white-sand beaches, all-inclusive resorts and its own international airport. and BavaroBávaroA beach area next to Punta Cana with one of the Caribbean's largest hotel clusters and a long white-sand shoreline. for the same beach traveler.

No point looking away: if this is a national problem for Mexico, for us it is a warning that no Caribbean shoreline is safe. We saw it in 2019 and again in 2022 in SamanaSamanáA north-eastern peninsula known for humpback whale watching, unspoiled beaches like Rincón and waterfalls such as El Limón. and Santo Domingo.

And here's the twist: this challenge opens a window for the Dominican Republic. Whoever manages their coast best gets the disappointed tourists cancelling their trips to the Mexican Caribbean. That means investment in anti-pollution barriers, beach cleaning equipment and an early monitoring plan led by MITUR.

• Satellite monitoring: anticipate before tons reach the shore.
• Floating barriers: technology already working in Punta Cana that can scale up.
• Honest communication: travelers reward transparency, not hiding the issue.

In my view, sargassum proves the Caribbean needs a joint climate strategy, not high-season patches. The silver lining: the destination that cracks it first takes the prize.
