Jamaica vs Punta Cana: sargassum compared
The Jamaica north coast has the more sheltered geography: Montego Bay and Ocho Rios face north, while the Punta Cana Bavaro strip faces the open Atlantic.
The reasoning
Why the map says what it says
Coasts pointed into the Atlantic catch most of what drifts in; coasts angled away from it miss more. That favors the Jamaican north shore on the map, but it is a tilt in the odds, not a wall: north-facing coasts still post High readings, and any of these three cards can surprise in either direction on a given week. Check all three below, then the cams.

Insufficient data
NOAA data did not cover enough of this coastline today for us to call a level.
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.
