Nevertheless, the seaweed problem is worsening in Cancun every year and if you are planning to spend quality time on the beach, then you want to avoid those 6 months of seaweed season.

March 19: A 5,000-Mile-Wide Mass of Seaweed Is Heading for Florida and Mexico

According to NBC News’ Denise Chow, a massive brown seaweed cluster spanning 5,000 miles is approaching North America, posing a potential threat to beaches across Florida, Mexico, and the Caribbean.

Although the massive collection of seaweed, referred to as the Great Atlantic Sargassum Belt, is not a new occurrence, experts have noted its current size as particularly substantial. Furthermore, the sargassum blanket, which can be found floating across the Atlantic Ocean, is reportedly arriving at coastal regions much earlier than usual this year. Brian Lapointe, an ecologist from Florida Atlantic University, warned that this development “doesn’t bode well for a clean beach summer in 2023,” in an interview with the New York Times’ Livia Albeck-Ripka and Emily Schmall.
