Tulum seaweed report
Tulum's open, east-facing coast takes the season's first and heaviest sargassum hits each summer.
The Quintana Roo sargassum monitoring network's late-June 2026 semáforo shows Tulum's main beaches (Paraíso, Pescadores, Ruinas, Santa Fe, Punta Piedra) at the top "excessive" level, and La Jornada reported on June 28 that 92.5% of the state's monitored beaches were at excessive levels in what officials call the worst season on record.
Significant accumulation likely. Have a plan-B beach ready.
Tulum is the Riviera Maya's boho-luxe icon: a long ribbon of white sand backed by jungle, clifftop Maya ruins and a low-rise hotel zone of designer cabanas. That same geography is its weakness during sargassum season. The coast faces the open Caribbean with no sheltering island and only a distant reef line, so drifting sargassum mats land here first and heaviest on the entire coast. In record-setting 2026, monitoring crews have already removed thousands of tons from Tulum's beaches, and at peak arrivals the shoreline can carry thick brown windrows and murky nearshore water despite daily cleaning.
Conditions still vary block by block and week to week. Hotel-zone properties rake their frontage from dawn and some deploy offshore barriers, while unserviced public stretches near the ruins accumulate the most. Arrivals come in pulses tied to wind and currents, so a bad week can be followed by a decent one. Use the monitoring network's beach-by-beach semáforo and live webcams the morning you plan to swim, keep cenotes and lagoons as a backup, and if clear water is the whole point of the trip, favor November through April.
Best spots in Tulum right now
Within one destination, orientation and cleanup crews make a big difference. Here’s how the main beaches compare today.
Caleta Tankah
Small, partly sheltered cove at the north end of Tulum; its curved shape and rocky points deflect some incoming mats, so it often reads a level or two better than the open beaches.
South hotel zone toward Sian Ka'an (Casa Malca / Arca area)
Hotel crews rake from around 5am and several properties use offshore barriers; sand is usually presentable by mid-morning even when arrivals are heavy, though nearshore water can stay murky.
Playa Paraíso and Playa Pescadores (north public beaches)
Fully exposed, east-facing public stretches with limited cleanup capacity; currently rated excessive on the monitoring semáforo and typically the worst-hit sand in Tulum at peak season.
Playa Ruinas below the archaeological site
The postcard cove under the ruins is unserviced and catches drifting mats against its rocks; at the moment it sits at the excessive level and is better admired from the cliff than swum.

Tulum seaweed FAQ
Is Tulum's beach swimmable right now (July 2026)?
At most main beaches, not pleasantly. The state monitoring network currently rates Tulum's public beaches at the top excessive level, and 2026 is tracking as the worst sargassum year on record. Hotel-zone sections that are raked from dawn can be usable in the morning, but nearshore water is often brown and murky during heavy arrival pulses. Check the semáforo map and a webcam the same morning before committing to a beach day.
Why does Tulum get hit harder than Cancún or Playa del Carmen?
Geography. Tulum's coast faces due east into the open Caribbean, directly in the path of the sargassum belt drifting in on wind and currents, with no offshore island to shield it. Cancún's north-facing beaches and Cozumel's leeward west coast deflect much of the same flow. That is why Tulum is routinely among the first and hardest hit spots on the Riviera Maya each season.
When is the best time to visit Tulum for clear water?
November through April is the reliable window: the sargassum belt shrinks, arrivals taper off, and beaches typically stay clean with turquoise water. Late December to March is safest of all. May through August is the peak-risk period, and in a heavy year like 2026 the season started unusually early, so shoulder months like April and October carry more risk than usual.
Do Tulum hotels actually clean the seaweed?
Yes, and it matters. Beachfront hotels like Be Tulum, Casa Malca and Nomade run daily crews starting around 5am, and some use floating barriers or nets offshore. On light-to-moderate days the sand is usually clear by 9am. During heavy pulses, though, new mats land with every tide, so even well-groomed sections can have seaweed at the waterline and murky water by afternoon.
What should I do in Tulum if the beach is covered in sargassum?
Tulum arguably has the best backup plan on the coast. The cenotes, including Gran Cenote, Dos Ojos and Casa Cenote, offer clear freshwater swimming and snorkeling unaffected by seaweed. Kaan Luum Lagoon is a turquoise inland swimming spot, Sian Ka'an boat tours explore clean lagoon channels, and the ruins, town restaurants and beach-club pools fill out the days. Many travelers plan beach mornings and cenote afternoons.
