Sargassum Cancun: Daily Seaweed Beach Photos, Forecast 2024

In 2024, the sargassum seaweed season in Cancun is anticipated to start earlier than usual, following the trend from 2023 when it began in February. Typically, the season starts in early spring, triggered by rising ocean temperatures that facilitate seaweed growth and reproduction.

Beaches most affected by high concentrations of algae include Playa del Carmen, Tulum, Sian Ka’an, and certain areas between Cancun and Puerto Morelos.

However, accurately predicting which beaches will be affected and to what extent is extremely difficult, as conditions change almost daily and often without notice. 

Read on for the latest information on the sargassum situation at these beaches.

Sargassum Seaweed 2024 Forecast

According to a report by the University of South Florida Optical Oceanography Lab, there has been a significant increase in sargassum, with December 2023 reaching new record levels compared to previous years. This increase suggests that 2024 will be a major year for sargassum presence. The total mass reached 13 million tons in the previous year, causing issues along Florida’s coast and impacting the travel and tourism sector.

The adverse weather caused a large amount of sargassum to accumulate, yesterday afternoon Thursday, in front of the area of the Malecon, especially between the dock of San Miguel and the Fountain of the Buzo, which required a special deployment of personnel from the Cozumel municipality.

During the morning, workers of the Directorate of the Federal Maritime and Land Zone (Zofemat) called for the task of removing this algae from the beaches, before it began to fire bad smells, managing to collect about three tons of this organic material. Milón Zavala Aradillas, director of Zofemat, pointed out that, fortunately, during the night the currents changed, and much of the sargazo that had begun to recalcize was carried by the waters, in the same way as it arrived.

During January, the amount of sargazo arriving on the island was minimal, a situation that seems to be beginning to change, the official accepted.

Scientists in Florida measured another massive seaweed blob for the Caribbean

Scientists have alerted the public to a potentially record-breaking accumulation of sargassum seaweed near the Caribbean Sea, which could impact Florida’s coasts in 2024. The University of South Florida researchers noted that the December 2023 mass of about 5 million metric tons significantly exceeded the previous year’s figure. The sargassum bloom, influenced by factors like human waste, climate change, and agricultural runoff, represents an unpredictable and growing environmental challenge.

Cancun Sargassum 2024 Season To Begin Early, According To New Report

The Cancun Sun reports that in 2024, the sargassum seaweed season in Cancun and the Mexican Caribbean is expected to start earlier than usual. This follows an early onset in 2023. Sargassum, while vital to marine ecosystems, poses challenges when it grows excessively. The University of South Florida predicts an increase in sargassum in early 2024. Efforts to manage this include monitoring and clean-up initiatives, and innovative uses such as repurposing it as fertilizer.

What is the seaweed sargasso and what is causing it?

Sargassum is a type of brown seaweed that floats on the ocean surface and is known for forming large masses or “blooms.” It is distinctive for its leafy appearance and air-filled bladders that aid in buoyancy.

The recent increases in sargassum blooms, particularly in the Caribbean Sea and Atlantic Ocean, are attributed to various factors including nutrient enrichment from agricultural runoff and human waste, climate change, and altered ocean currents. These factors contribute to an environment conducive to the rapid growth and accumulation of sargassum, leading to significant environmental and economic impacts on coastal regions.
