Mexico Seaweed Daily Beach Updates: Cancun, PDC, Tulum, etc.

In 2024, the sargassum seaweed season in the Cancun Area 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 Cozumel, 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.

April 11: Massive Arrival of Seaweed to Mexican Caribbean from April 6

Massive invasions of seaweed started happening in the Mexican Caribbean. From April 6, people started uploading photos into our FB seaweed reporting group with huge amounts of seaweed on the beaches of Playa del Carmen, Puerto Morelos, Tulum, etc. This invasion continues throughout the week and it’s most likely caused by increased temperatures in the Caribbean.

Here are some photos from our FB group (April 7 – 10):

March 18: The seaweed situation in Riviera Maya in the first two months of 2024 is significantly better than last year

The local government confirmed that the situation in the first 2 months of 2024 was significantly better than in 2023. As per numbers, in January and February 2023 they collected 1000 tons of seaweed, and in 2024 was only 200 tons. This may have been caused by lower sea temperatures which are also lower compared to last year.

We also compared photos from our FB seaweed reporting group, and the results are clearly noticeable.

When Does Seaweed Season Start In Cancun (Mexican Caribbean)?

According to the data from the last 2 years, seaweed season in Cancun starts in February and peaks between April and August. Some parts close to Cancun, such as Playa del Carmen, Cozumel, and Puerto Morelos see the start of the peak already in February.

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.
