Seaweed (sargassum) is a natural phenomenon that has affected the beaches of the Mexican Caribbean in recent years, especially in tourist destinations like Cancún and Tulum. Although its arrival can be unpredictable, there are ways to plan your trip to enjoy the best beaches without seaweed. In this guide, we’ll tell you when seaweed is expected in 2025, which beaches are usually free of this algae, and how to move around comfortably during your stay.
What is Sargassum and Why Does It Arrive in Cancún and Tulum?
Sargassum is a type of seaweed that originates in the Atlantic Ocean and accumulates in the Caribbean Sea due to ocean currents and changes in water temperature. Although it is a natural part of the marine ecosystem, excessive amounts can affect the beauty of the beaches and generate an unpleasant odor as it decomposes.
In recent years, the Mexican Caribbean has experienced an increase in sargassum arrivals, prompting authorities and hotels to implement strategies for its cleaning and management. However, its presence varies depending on the season and location.
When Does Sargassum Arrive in 2025?
While the arrival of sargassum is not entirely predictable, past records indicate that the most intense season is typically between April and September, with a peak in the summer months. During winter and early spring, sargassum levels are lower, making these months ideal for visiting Cancún and Tulum without worries. It’s advisable to check updated reports on sargassum before traveling. Several websites and social media channels monitor its presence in real time, which can help you plan your beach days more effectively.
