Cancún seaweed report
2026 is a record sargassum year, but Cancún's sheltered north-facing bay beaches are staying clear
The Red de Monitoreo del Sargazo traffic-light map for June 29, 2026 showed excessive seaweed at Punta Cancún, Playa Gaviota Azul and Playa Chac Mool and abundant levels at Playa Marlín and Playa Ballenas, though Langosta, Tortugas and Caracol stayed green. Satellite updates from the University of South Florida show dense mats still in the approach corridor, with heavier pulses expected through July.
Noticeable seaweed. Cleaned resort stretches and mornings are usually fine.
Cancún's Hotel Zone is a 22-kilometer barrier island of high-rise resorts strung along some of the whitest sand in the Mexican Caribbean. Because it sits at the northern tip of Quintana Roo, it generally receives less sargassum than Playa del Carmen or Tulum, but in a record season like 2026 the exposed beaches can still wake up under thick brown mats. Municipal crews and hotel staff rake most beaches every morning, and the city has already removed more than 15,000 tons of seaweed this year, so conditions often look far better by mid-morning than they do at dawn.
Geography drives everything here. The island bends like a seven: the north-facing stretch from Playa Las Perlas through Playa Tortugas to Punta Cancún is shielded by Isla Mujeres and stays largely clear, while the east-facing strip from Playa Gaviota Azul down toward Playa Delfines takes arrivals head-on. The season runs roughly April through October and peaks June to August. Use the current rating for today's snapshot, the area ratings to pick a specific beach, the monthly pattern to time a future trip, and the live cams to check the sand before you head out.
Best spots in Cancún right now
Within one destination, orientation and cleanup crews make a big difference. Here’s how the main beaches compare today.
Playa Tortugas
North-facing on Bahía de Mujeres and shielded by Isla Mujeres, so seaweed rarely lands here. Calm, swimmable water and the Isla Mujeres ferry pier; rated green (low arrival) on the June 29 monitoring map.
Playa Langosta and Playa Caracol
The rest of the sheltered north shore near Punta Cancún. Both were green on the June 29 traffic-light report and are considered among the most reliably clear beaches in the Hotel Zone even at peak season.
Punta Cancún, Playa Gaviota Azul and Playa Chac Mool
The tip of the seven catches currents head-on and is typically the first stretch to receive arrivals. All three points showed excessive (red) accumulation on the June 29 report despite daily cleanup crews.
Playa Marlín to Playa Delfines
The long east-facing strip takes the full brunt of incoming mats; Marlín and Ballenas were orange and Delfines yellow on June 29. Crews aim to rake the public beaches clear before 8 a.m., so mornings after cleanup look best.

Cancún seaweed FAQ
Is there sargassum in Cancún right now?
Yes. As of the June 29, 2026 monitoring-network map, the east-facing and Punta Cancún beaches, including Gaviota Azul, Chac Mool, Marlín and Ballenas, had abundant to excessive seaweed, while the north-facing bay beaches like Tortugas, Langosta and Caracol were rated green. Conditions change daily, so check the live cams and the latest traffic-light map on the morning you plan to swim.
Which Cancún beaches have the least seaweed?
The north-facing stretch along Bahía de Mujeres is your best bet: Playa Las Perlas, Playa Langosta, Playa Tortugas and Playa Caracol. This shoreline is shielded by Isla Mujeres and receives currents at an angle rather than head-on, so it stays largely clear even when the east strip from Chac Mool to Delfines is buried. It is also calmer water, which makes it popular with families.
Is 2026 a bad year for sargassum in Cancún?
Yes, 2026 is tracking as one of the worst seasons on record. The University of South Florida's ocean lab reported record Atlantic sargassum quantities, arrivals began unusually early in January, and Quintana Roo authorities expect to collect more seaweed than in 2025. That said, Cancún fares better than Playa del Carmen or Tulum, and its sheltered northern beaches have stayed mostly clear through late June.
Do Cancún hotels clean the seaweed off their beaches?
Yes. Beachfront resorts run their own raking crews, and municipal teams work the public beaches with the stated goal of having Hotel Zone sand cleared before 8 a.m. each day. More than 15,000 tons had already been removed from Cancún's public beaches by mid-June 2026. Heavy overnight arrivals can still outpace crews at exposed spots, so beaches usually look best from mid-morning onward.
When is the best time to visit Cancún to avoid sargassum?
November through March is the reliable low-seaweed window, with December to February typically the cleanest and clearest water. The season generally builds from April, peaks June through August, and tapers through October. If you must travel in summer, book on the north-facing stretch between Playa Tortugas and Punta Cancún, or plan cenote, reef and island excursions for days when the east strip is hit.
