NOAA satellite risk for every stretch of coast. Report of October 21, 2026.
Each line is a stretch of coast, colored by NOAA's risk of sargassum reaching it. It's a satellite estimate for the coast, not a check of a specific beach.
Wind next 2 days: mostly from the northeast, 7–13 mph (NOAA global forecast model). Wind blowing toward a coast pushes floating sargassum onto it, so north- and east-facing beaches are more exposed. A hint, not a sargassum forecast.
Mexico's Red de Monitoreo del Sargazo de Quintana Roo publishes a daily beach-by-beach color alert (semáforo) on its social media. Check it for the latest local reports.
