Live Seaweed & Sargassum Map — Cancún and the Riviera Maya
Updated June 21, 2026 from Copernicus satellite data — refreshed 4× per day.
This is an interactive, live map of the sargassum — the seaweed — across the Mexican Caribbean: every beach, from Holbox to Mahahual, shown with a color-coded status (clean, moderate, or avoid). It's fed by Copernicus satellite imagery refreshed four times a day, plus reports from people standing on the sand right now. Tap any beach for its current status, a 0–100 Beach Score, and the 7-day forecast. Unlike a seasonal guide, this map changes when the sea changes: an overnight wind shift can clear Cancún and load Tulum by noon. Check it the morning you go.
