Knowledge Base

Is there sargassum right now?

Levels vary by the beach. North Tulum (Ruins) often sees different conditions than South Beach (Hotel Zone). Use the pulse above for today's specifics.

Which months are the clearest?

Historically, November through March offer the most reliably clear waters, as the Caribbean currents shift and water temperatures cool.

Is it safe to swim?

Yes. Sargassum is non-toxic algae. However, as it decomposes on shore it can release a distinct sulfur smell. Most high-end beach clubs clean their shorelines manually every morning.
