Sargassum arrivals in Tulum are seasonal and can vary week to week. Some days the water is crystal clear; other days crews are actively cleaning the shoreline. The key is flexibility: check conditions the morning you plan to visit the beach and have a “Plan B” ready—cenotes, ruins, lagoons, spas, or food tours are great alternatives.

On heavier seaweed days, consider beaches that are more sheltered, wear water shoes, and pack a light cover-up. Biodegradable reef-safe sunscreen is recommended year-round. If you’re booking a stay, ask your host about nearby stretches that were clear the previous days and typical cleanup times. With a little planning, you can still enjoy plenty of sun, swim spots, and photo-worthy moments.
