of the coast.
A beach is more than a pin on a map. We’re building a clearer way to understand changing conditions and decide where to go.

Less guesswork.
More perspective.
Sargassum can change a beach day. Sargassum Check is our starting point: a Mexican Caribbean map covering 79 beach and coastal-area records. The public beta shows rough, low-confidence estimates with dated evidence and coastal assumptions.
Explore Sargassum CheckKnow the confidence.
Sparse evidence means low confidence. That uncertainty appears alongside each estimate.
Look behind the answer.
Open “Why” to inspect source dates, age and assumptions. Regional conditions do not confirm what is on a particular shoreline.
An honest starting point
The beta provides rough, low-confidence estimates. It does not provide confirmed beach observations, calibrated forecasts or a swimming-safety assessment. Coverage and supporting evidence are still developing.
