Sargassum at Puerto Morelos main beach: today's conditions
Heavy
Fucking mess
Puerto Morelos main beach runs along the seafront of a small fishing town on the Caribbean coast of the Riviera Maya, halfway between Cancún and Playa del Carmen. It marks the northern end of the mainland stretch that continues south to Tulum, and it is the departure point for boats heading out to the reef.
This page tracks sargassum at Puerto Morelos so you know what to expect before you walk down to the sand: the condition observed today on this shoreline, a 0 to 5 rating that sums it up in one glance, and a map placing the beach within its section of coast. Everything is refreshed each morning.

What to know about this beach
The beach faces due east, straight into the open Caribbean, so the easterly trade winds that carry floating sargassum rafts push them directly onto this shore. What sets the town apart is the reef: the Mesoamerican barrier runs unusually close to the beach here and encloses a shallow lagoon protected as a national park.
That barrier changes how landings behave. It flattens the swell and keeps the water calm, but it also holds on to whatever crosses the coral line: a patch that drifts into the lagoon tends to linger instead of being pulled back offshore. When the wind swings north or drops away, arrivals ease off quickly. The town front is short, so a single walk covers most of the sand.
Frequently asked questions
Why does sargassum reach Puerto Morelos?
The beach faces due east into the open sea, and the trade winds push drifting rafts straight towards it. The nearby reef calms the waves but also traps whatever manages to cross the barrier.
How can I check the beach before going?
Open this page in the morning: FanGass publishes a daily 0 to 5 rating for Puerto Morelos along with a map of the surrounding coast, updated each morning rather than the night before.
When is sargassum most likely here?
Landings usually cluster from spring through late summer, when winds and currents carry the most weed westwards. Winter months tend to be quieter, though no season is ever guaranteed either way.
Does the reef lagoon make a difference?
Yes. It keeps the water shallow and sheltered, which is good for swimming, but weed that drifts inside takes longer to wash back out than on an open, unprotected shore.
