Update on Sargassum Seaweed Affecting Mexico’s Beaches

The continued presence of sargassum seaweed (a.k.a sargasso, sargazo) on the beaches of Mexico continues to be a concern to many travelers. For those wondering what their experience will be like on their upcoming vacation, we invite you to read more about the problem and how local authorities, hotels, and students are handling the situation.

Latest on sargassum

The 2022 sargassum season began at the beginning of spring due to a rise in sea temperature, which accelerates the reproduction of the seaweed. As the days get warmer, the presence of sargassum is expected to increase. Beaches with the highest seaweed count include Playa del Carmen, Tulum, and some points between Cancun and Puerto Morelos.

The Mexican government and hotels in the Yucatan Peninsula have stepped up their efforts to tackle it, however, the majority of low-budget hotels and hostels do not have the means to clean their beaches on a daily basis.

If you’re keen to avoid sargassum on your Mexico visit, make sure to stay in a hotel that has staff constantly monitoring the ever-changing situation and has the means to tackle the issue.

Plan your vacation with Journey Mexico and we can help you find a hotel that has the means and resources to clean their beaches every day and keep your vacation as sargassum-free as possible.

Latest news on sargassum seaweed

Rear Admiral César Gustavo Ramírez Torralba, Coordinator of the Sargassum Attention Strategy and Secretary of the Navy, has reported that in the coming days, a barrier will be stationed in front of Puerto Morelos.

In the first week of April the sea barrier will be installed in Playa del Carmen, and again in Tulum in the second week of April. In Mahahual, progress stands at 500 meters of installation, with completion expected this week. Rear Admiral López added that sargassum collection vessels will also be used at sea to catch sargassum before it reaches the coast.

The Governor of the state of Quintana Roo, home to the Riviera Maya, has commented “We know this is a natural phenomenon that generates adverse conditions, but we will be working with the Secretary of the Navy, the municipalities, hotels and the private initiative with our best efforts to keep the beaches clean so that they continue to be a great tourist attraction,”.

Updated March 2022: As part of our on-going efforts to monitor the sargassum seaweed situation, we are in regular contact with our hotels in the affected areas.

Below are the latest images from the Riviera Maya and Isla Holbox:

What action are the hotels taking?

Paradisus Playa del Carmen: When sargassum is present on the beach, the hotel manually cleans the seaweed throughout the day. 

Andaz Mayakoba: When sargassum presents, the resort sends a boat out to fish the seaweed out of deep waters and a team of 20 people manually cleans the beaches daily. 

Jashita: In the case of sargassum, the hotel has a team of people that manually clean the beach throughout the day. 

Banyan Tree Mayakoba: When the seaweed appears, the resort´s staff clean the beach daily. Depending on the volume of sargassum, this may be done manually or using machinery. 

Chable Maroma: The hotel carries out daily cleaning when necessary, employing a tractor and team of staff from 7am to 3pm.

Everything you need to know about sargassum

What is sargassum?

Sargassum is a brown seaweed with buoyant, oxygen-filled bladders that keep it floating on the surface of the water. It can clump together in huge masses, often miles long, and has been known to wash up on the shores of beaches along the Caribbean coast from the United States all the way to Argentina.

As reported in our post “Mexico and Mother Nature – What you Need to Know 2015“,  the sargassum occurrence — which has many ecological benefits — is not dangerous nor continuous and often unpredictable. One week there may be large mounds of seaweed heaped on the beaches and obscuring the translucent sea, while others the beaches are perfectly clean.

Many hotels are taking measures to provide clear beach access through clearing the seaweed and removing it from the beach, while others are unable or unwilling to do so due to a lack of human and financial resources, an unwillingness to alter naturally occurring patterns or long-term concerns that the seaweed will actually protect and enhance their beaches.

The seaweed accumulation has been most prolific on stretches of exposed beach and less noticeable in areas that are protected by natural headlands, bays, or coves. Read more: What You Need to Know about Sargassum Invading the Caribbean.

Where is it coming from?

To find out exactly where sargassum is coming from and how it ends up on Mexico’s coast, we spoke to Florida Atlantic University’s Dr Brian Lapointe, a research professor and leading expert on sargassum.

He told us that, after studying satellite imagery, it’s understood there is a large amount of seaweed growing between the coast of Africa and Brazil, an area they have coined the Great Atlantic Sargassum Belt.

In that region, there is a range of nutrient sources that are feeding the sargassum and helping it to bloom. These include nutrient-rich run-off from the Amazon River and the Orinoco. There is also a phenomenon known as upwelling, in which nutritious seawater rises from the bottom to the top of the ocean, which helps to feed the floating plant.

Dr Lapointe also pointed out that he has seen areas of low temperature off the coast of Africa, which could indicate nitrogen is coming from the deep seas. Other sources of nutrients include Saharan dust coming from Africa.

The seaweed is moved from the Great Atlantic Sargassum Belt to Mexico and the Caribbean region by hitching a ride on currents. As it makes it way along these streams, the sargassum picks up more and more nutrients and continues to grow.

Sargassum seaweed facts

  • Floating sargassum rafts provide a wonderful natural habitat for many sea creatures. According to the National Oceanic and Atmospheric Administration, fish, sea turtles, marine birds, crabs, shrimp, and more all call this floating island home.
  • There are more than 300 different species of sargassum including sargassium muticum (more commonly known as Japanese wireweed), and sargassum horneri (also known as devil weed).
  • The Sargasso Sea is the only sea in the world without a land bordering it and, as you might expect, is home to large swathes of floating sargassum seaweed. The sea itself was reportedly discovered by explorer Christopher Columbus and his crew who crossed it in 1492.
  • In 2018, Quintana Roo businessman Omar Vázquez Sánchez made good use of the local sargassum build-up when he built an earthquake- and hurricane-resistant home from a mixture of sargassum and adobe.

    Excellent information.

    Many thanks as we are now reconsidering our travel options back to mexico and the Mayan Riviera.

  2. Rebecca Rogers

    Yes thank you for this information – I could not find easily whether it had improved this fall as expected or not. So feeling better about traveling there for the fall/winter.

  3. JTS

    Anyone have an update on beaches of Tulum and seaweed issue ? Is it clear ? Water – algae clear ? was hoping to be there in late November so curious from someone on the ground there what the status is. thanks

      • Yan

        We are thinking to book Riviera Maya over the Thansgiving. Is the seaweed problem still an issue?

        • Jessica S.

          Hi Yan, As you can read above, it really depends day to day and hotel to hotel. We’ve been monitoring weekly and have consistently rated them around an 7-8 (10 being perfect conditions!)

  4. Alvin Tong

    We appreciate any update on Moon Golf Palace and Spa in Cancun. We have planned a college reunion from Dec 1 to 8 there. Thanks.

  5. Larry Gilliam

    We are sheduled to travel on Nonvember 14th to the Grand Park Royal Caribe Cancun. I would appreciate any input on conditions on the beach.

  6. Christine Barth

    I was thinking of booking a week’s vacation at the hotel El Cid. Wondering what the beach is like because it has received very bad reviews about the seaweed problem and the inability to clear it by man.

  7. Carlo Derra

    I’m in tulum right now. I’ve been told.the situation in much better than before, but if you expect turquoise water and white beaches you’ll be disappointed. The sea has still A LOT of seaweed and close to the shore is brownish, rather than blueish. They rake the beach, sure and make some nice little smelly mounds few meters away.

  8. Melissa

    I just returned from mayan riviera last Thursday, and I was sadly disappointed in the condition of the water, it was not my first time here, and from what I remembered to what I saw this year, a huge difference. Very murky, no blues and greens to it at all, could barely even snorkel in it. I stayed at the grand sirenis. And the piles of seaweed on the shores had an awful smell to them. They were out cleaning it from the shores but it’s all over the sea, just floating there 🙁

  9. saundra

    wondered how the seaweed is at secrets Akumal and secrets Maroma beach. Going in feb 2016.

    • LInda

      If you get any type of reply, please share as we are planning to go to Akumal in February as well. Thanks!! Linda

      • Jessica S.

        Hi Linda, we suggest contacting your hotel directly to see their current status, keeping in mind that it changes daily! I’m sure no matter what, you will have a lovely vacation! Safe travels!

  10. Merry Wheaton

    Wondering how the beach and water are in Akumal bay, at Villas Maya and Club Akumal Caribe–the original resort area there. Thanks!

  11. Jose Noriega

    The barber surf rake is a good option to keep the beach free of seaweed. They are not cheap, but it’s a good investment! Maybe to make it affordable, neighboring resorts should get together to foot the bill. These machines can clean a big area quickly. They can probably even make business by rent it to get their investment back. It just one of my thoughts……

  12. Matt Jenatscheck

    We are traveling to the Valentin Imperial in the next month. Are there any reports on the beaches there, in specific?

    • Adam

      I’ll be there in March…would love to know about the status of their beach..I know they have implemented a tractor removal twice daily for the seaweed…however recent pictures ive seen (Dec 2015) of the beach look beautiful.

  13. VIncent

    Thank you for updating potential visitors on this seaweed situation.
    Can you tell us about the situation in January? Do you think that all the actions put in place since last summer will be in full effect and therefore there should not be any seaweed on the shores of Tulum during December January and beyond?
    Thank you

    • Jessica S.

      Hi Austin, our update remains the same from Maroma. As mentioned, things change on a daily basis so won’t be able to forcast out till June. Maroma has implemented intensive cleaning procedures so I’m sure you’re vacation will be just perfect! We haven’t received any negative comments from our guests at Maroma.

      • Mary

        The hotels can clean the beaches but the seaweed still makes the water very unpleasant. If one doesn’t want to go into the water, you may be happy with the beach cleaning efforts.

  14. Joana

    Thanks for the useful information. I’ve been here since Sat 5th and Playa Paraiso (Tulum) and Akumal had been mostly clear thus far. Not sure about yesterday, but today Playa Paraiso and Ziggy beach (both in Tulum) are filled with Sargassum. It did not rain at all during the week, so could not have been the rain that caused it.

    • Jessica S.

      Hi Joana, thanks for the update! Yes, things change on a daily basis, crazy how fast it happens! Hopefully it will get cleaned up soon so you can return to enjoying the beaches of the Riviera Maya!

  15. Vanessa C

    I just booked a vacation for a once a year get away at Dreams Tulum January 19th-25th. The beach is the most important part of my experience during vacation. Dreams assured me that they clean daily, conditions are clear, etc. prior to my booking but I’m sure they have a vested interest in my booking and not scaring us away with tales of murky waters and seaweed. I found this page to be the most helpful in guiding me through the seaweed. Please keep it honest… Any updates on that area would be most appreciated!!!

    • Julie

      I’ll be there from the 14th – 18th. I’ll try to remember to post an update for you. As of right yesterday, I heard from someone else that it stinks like raw sewage and staying poolside is best.

  16. edd

    Any update about seaweed in Cancun or Riviera Maya please. I have a plan to go there in last week of January 2016.

  17. Michael M

    How is it at Grand Sunset Princess? How about Play de Carmen?

    Also how is Isle de Merelas

    • Jessica S.

      Hi Michael, we suggest reaching out to the hotel via social media or e-mail to inquire if they have a beach cleaning program in place and real-time photos they can share.

  18. Bob Deutsch

    12/25 – Report from Tulum. Beach in all areas 3/4 covered with seaweed. Up near the public access, there is a small mountain (looks like a landfill) of the stuff that they have piled up. Water is full of the stuff. We were here a year ago, if anything, it is a bit worse. We will be in Pusrtto Morelos in a few days and will report back. A bummer. Sad for the area.

    • Jessica S.

      Hi Bob, thanks for sharing your experience. Can you please be specific in where you were in Tulum and from which hotel? The situation varies daily and also from hotel to hotel/beach to beach. Thank you!

  19. Cara

    I just returned from visiting both RIU Cancun and Secrets Maroma. RIU had no seaweed along with most of Cancun I believe. Secrets Maroma had minimal. Didnt stop us from going in ocean. They cleaned daily. A couple days were pretty clean and other days had seaweed but not bad. Varies daily so expect to see seaweed and don’t let is stop you from visiting! Water was still beautiful green/blue.

  20. Jenna

    Got to Dreams Riviera Cancun in mid February. Hope things are looking better by then! Anyone been there recently?

  21. Robert

    Great to receive these updates, heading down in February. We were in Tulum last year and areas were just fine, others parts were hit hard, but efforts made to continually clean the beach.

  22. Hoji

    We were in Playa Secreto/Puerto Morelos area over holidays and didn’t even want to go in the ocean there was so much seaweed. Smell was ok, and vacation was still wonderful, but disappointing none the less.

  23. Cassker

    We want to book a trip in med April, any thoughts on the lovely seaweed to be cleared by then?
    What about Cozumel?

  24. Cindy

    Thinking about heading down the end of February to Cabanas Los Lirios in Tulum. Has anybody been to this area and any recent feedback would be lovely. Thank you

  25. Mandy

    Hi Jessica, thanks for the post and updates. We have a trip planned in 9 days to BlueBay Resort – south of Cancun. We are thinking about using the insurance to change the dates because of the weather forecast… Can you tell me what you’re experiencing temperature wise. When the forecast says cloudy or rainy m, does that mean all day typically? … According to weather.com and accuweather.com we will have 1 partially sunny day and 1 mostly sunny day out of the 7 we plan to be there. We will arrive in Sunday January 25th and stay until Saturday. Any help you can provide will be greatly appreciated!! Sincerely, Mandy

  26. pat

    heading to capri secrets riviera jan 30-feb 6. any information on weed problem there? will be helpful, thanks.

  27. elke

    We are going to the finest isla mujeres. Does anybody know if the beach is affected . We are going middle of March2016.

  28. Meredith

    Hello All!

    I see there hasn’t been a seaweed update for Tulum/Playa del Carmen in quite a while. In general how are things?

    I am planning Tulum next month but noticed last summer in both Playa and Tulum that they are not nearly as equipped to handle the massive seaweed cleanup as in Cancun for example.

    Any updates on seaweed proliferation and/or new cleanup efforts in these areas would be greatly appreciated. Last summer was miserable not being able to even get in the water, not to mention the smell.

    I hear Isla Mujeres is great now but I prefer Tulum:)

    Thanks in advance!

    • Jessica S.

      Hi Meredith, in general, things remain the same from our last update and we have seen no major changes or influx. From Cancun to Tulum, the region has made great efforts in cleanup.

  29. Michelle

    This is great information. Thanks for taking the time and being so detailed with your facts. I’m considering having my wedding at the Now Jade in Riviera Maya in November 2016. Any information on whether or not they’re actively cleaning their beach?

  30. Mandy

    There is some great information here! I am planning a holiday to Now Sapphire Riviera in November 2016 but am now concerned to read about the seaweed problems. Do you know what the beach is like in this area now or predictions for November this year? Is it likely to reoccur?

    I don’t really want to change the location of my holiday but I’m after an exotic beach location – its such a shame

    Any help would be much appreciated, thanks

  31. Maria

    we are coming to Playa del Carmen march 21. Please let us know where in the following places there is NO seaweed and is best for swimming with children terrified of seaweed. Thanks.

    Playa del Carmen
    Isla Mujeres

    Thank you!

  32. Matt

    Hi, thanks so much for this great information. We are traveling to Tulum on March 29 for a week (staying at Ahau Tulum). Do you have any recent updates on the seaweed situation in Tulum or near Ahau specifically? I am also checking with the hotel manager.



  33. Joe S.

    Does anyone know if they installed those nets yet to avoid the sargassum coming to the beach?

  34. BB


    My family and I are trying to plan a trip to either Cancun or Playa Del Carmen for the end of May. This will be our first time vacationing in that area. We’re going for the white sand beach and clear blue water, however I heard about the seaweed problem and I’m now hesitant to make a reservation. Are there any updates on the current situation?

  35. Margo Hutchison

    We will be in the area in January 2020 and are trying to decide where to stay based on the sargassum issue. Can you send me a realistic update.

  36. Anusheh Fawad

    Hello, I was wondering how often you update the Sargassum seaweed map? is the just the Sargassum seaweed that affects the beaches? I will be in Cancun Nov.27-Dec4. 2019 in the Puerto Morelos areas and very interested to know the condition of beaches.

    • Sam Murray

      Hi Anusheh, good to hear from you. We update the Sargassum seaweed map on a weekly basis. If you already have a hotel booked, we suggest contacting them directly to ask them about their beach cleaning procedures.

  37. Chad

    Holbox November 11, 2019….large amount of seaweed on all the beaches. Cancun November 13…no seaweed at all.

    • Mike

      We stayed in Cancun in January 2020 and it was fine. No seaweed. They generally do a good job at the cancun hotels in cleaning the beaches . And the beaches are larger than the riviera maya. Mike

  38. Barb

    We are planning a trip to Grand Sirenis riviera maya resort for mid Feb. 2020. Any feedback about the seaweed issue at that time of year?

  39. Barbara Blieu

    June 2021, still there. But cleaned up every day at the resorts. Just wade out past it and you are good.
    Riviera Maya area!!

  40. joe

    Holbox is not normally impacted by sargassum since its beaches are far north of the peninsula as of today June 28 we continue without any.

  41. ferahtia.FS

    Your posts are very instructive, which I later learned a lot from. It was great I hope you get more new posts! I am one of your Permanent Visitors
