Varadero vs Cancun: sargassum compared
Varadero has a modest geographic edge: the Hicacos peninsula faces north toward the Straits of Florida, while the Cancun hotel zone faces the open Atlantic path.
The reasoning
Why the map says what it says
An edge is not a shield. The satellite record on both pages below shows High readings at Varadero as well as Cancun in peak weeks, so treat the orientation difference as a tilt in the odds and let the current cards settle the week you are booking. Neither page has a verified cam yet, so a same-day photo from the resort is the closing move for either.

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.
