Sargassum

As sargassum blooms hit Honduran Caribbean coasts, a national strategy launched in August aims to move beyond cleanup toward productive uses—following Mexico's research showing the seaweed contains valuable nutrients for agriculture, biofuel, and industrial applications.

Tourism officials in the Bay Islands are promoting Roatán, Guanaja, and Utila for the upcoming Morazán Week holiday, while also addressing sargassum accumulation on beaches with a planned cleanup on Sunday.

NASA and Mexican university satellites provide near-daily tracking of sargassum accumulations drifting across the Caribbean toward Honduras's northern coast, with public tools like UNAM's Sargassum Viewer allowing beachgoers to monitor patches and check their distance from shore.

Public agencies and private tourism organizations in Tela, Atlántida, joined forces on Saturday to clear sargassum seaweed from the municipal beach, removing accumulated algae that degrades the coastal environment and affects the tourist industry.

Sargassum coverage in the western Caribbean near Honduras totaled roughly 1.7 million metric tons in August, down from July peaks but still above historical norms, and the University of South Florida projects continued decline over coming months.

La Ceiba's municipal government began removing massive accumulations of sargassum seaweed from over two kilometers of central beach ahead of the Morazán holiday tourism surge, with crews and heavy machinery working to clear the area before visitors arrive.

As sargassum seaweed threatens Honduras's most-visited beach destination ahead of the Morazán holiday, Tela's municipal government has activated cleanup crews and contingency plans to protect tourism and public access to the shoreline.

Representatives from the Education Ministry's Department of Environmental Education and Health trained teachers and school directors in Roatán and Santos Guardiola on environmental awareness, circular economy practices, and health care, addressing local challenges including sargassum seaweed on island beaches.

A thick accumulation of sargassum seaweed blanketed Omoa's beach in Cortés on Friday morning, forcing fishermen to suspend operations and trapping fish that had to be rescued.

Sargassum seaweed arrived on Omoa's Caribbean beaches two days ago, disrupting fishing and threatening tourism during the busy Morazán Week holiday, with local authorities organizing cleanup crews to keep the coastline clear.

Twenty-six government and international agencies convened to develop strategies for managing sargassum affecting the Bay Islands' coasts, exploring uses such as fertilizer and biofuel while Roatán faces cleanup costs of roughly L1 million every 15 days, with Germany and Portugal offering up to €20 million in support.

Roatán's municipality is stepping up weekly or biweekly beach-cleaning crews during the March–September peak season to remove sargassum and solid waste from Guatemala (via the Motagua River) and Puerto Cortés that wash ashore on the island's unmonitored beaches.

Monitoring by the Roatan Marine Park reveals sargassum seaweed is spreading into northern and western zones of Roatán where concentrations were historically low, with climate instability making the algae's behavior harder to predict and manage.
