Stale data
Our newest NOAA observation is too old to stand behind, so we hold the level back rather than pass it off as current.
Head to head editorial
Cancun vs Punta Cana: sargassum compared
Neither is the sheltered pick: Cancun and Punta Cana both face the open Atlantic, so geography does not separate them.
The reasoning
Why the map says what it says
Seaweed drifts in from the Atlantic and lands mostly on coasts that face it, and both of these do: the Cancun hotel zone faces east, Bavaro faces east and northeast. That makes this a comparison the day-to-day data has to settle, not the map. Check both cards below, then the cams. If shelter matters more to you than either resort zone, the different geometries nearby are the Cozumel west coast and the Jamaica north coast.

The record
November, five years back satellite-derived
Raw satellite floating-algae detections near each coast for this month in each of the past five years (brighter orange and red = stronger signal). These are detections, not risk ratings: clouds and glare can hide algae, offshore mats do not always land, and the nearshore strip is blanked where the signal is unreliable.

Making the call
How to decide
- Read the cards above, including the full mix of levels, not just the headline.
- Open a beach cam for each contender if one exists; nothing beats looking.
- Ask each hotel for a same-day photo of its swimming beach.
- Remember the atlas rates coastlines, not resorts: one cove can beat its neighbor on the same morning.
