Sargassum Videos on Social Media Spark Tourist Concerns in Mexican Caribbean

Cancún, Quintana Roo — Videos and images showing an early arrival of sargassum seaweed on beaches in Cancún, Playa del Carmen, and Tulum are circulating on social media and international news sites, raising concerns that could influence travel decisions to the Mexican Caribbean.

This trend of content highlighting the macroalgae’s presence complicated the 2025 summer season, as other vacation destinations used the natural phenomenon to attract tourists with campaigns claiming they were sargassum-free.

Pablo de Zulueta Razo, head of the Municipal Tourism Department in Benito Juárez, said authorities are promoting a campaign on official websites and social media emphasizing that sargassum does not appear every day or on all beaches. They are also conducting constant monitoring to inform tourists which beaches are clear of the seaweed.

He noted that some content creators spread misinformation or serve the interests of other destinations running negative campaigns to capture tourists, but the important thing is that authorities are addressing the seaweed influx and the beaches look spectacular.

In contrast, several European media outlets have republished photos and videos showing how sargassum arrived early and in massive quantities on Riviera Maya coasts, affecting tourism activity and local businesses.

Users on TikTok, Facebook, Instagram, and X are sharing clips of brown patches washing ashore, alerting tourists that sargassum is obscuring the Caribbean’s turquoise blue waters; some even suggest reconsidering travel to the region.

Additionally, some tourism-focused websites mention a report from the University of South Florida’s Optical Oceanography Laboratory, which projected high sargassum levels across the Caribbean, potentially influencing travelers to modify their plans.
