The first thing I notice as the speedboat pulls up to the dock at Margaritaville St. Somewhere Punta Coco by Karisma Resorts on Isla Holbox is how utterly void of seaweed the turquoise waters of the Caribbean are here. While much of the Riviera Maya coastline is currently muddled by a sea of Sargassum, in Holbox, there is nary a string.
There is, however, a long, near-empty stretch of porcelain white sand beach juxtaposed against a calm sea colored in varying shades of blue and green. The lack of seaweed when I visited wasn’t a fluke. Isla Holbox is just outside the gulf stream current belt that delivers the smelly, slimy brownish grass to beaches in Tulum, Playa del Carmen, and Cancun each summer.
