Playa del Carmen
Insufficient data
NOAA data did not cover enough of this coastline today for us to call a level.
Head to head editorial
Playa del Carmen vs Tulum: sargassum compared
Expect similar odds: Playa del Carmen and Tulum sit on the same east-facing coast about an hour apart, with the same exposure to the open Atlantic.
The reasoning
Why the map says what it says
When two beaches share a coastline and an orientation, the geography that matters most at booking time is identical, so this choice usually comes down to the towns rather than the seaweed. The cards below can still differ on a given day, and that is worth a look before you book. The genuinely different geometry nearby is the Cozumel west coast, which faces away from the open Atlantic.

The record
September, 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.
