Punta Cana SEAWEED Problem (2022): Everything You Need To Know!!

Is there still a seaweed problem in Punta Cana in 2022? If you’re thinking about visiting Punta Cana in 2022, you’re bound to have this question. Punta Cana, along with other Caribbean countries, is currently facing a huge sargassum crisis.

Sargassum seaweed has been a big problem for Caribbean countries since 2011. However, the frequency and quantity of sargassum washing up on Caribbean beaches has considerably increased since 2015.

The year 2018 was particularly bad, as a large amount of sargassum seaweed landed on the shores of many Caribbean countries, ruining their pristine white sand beaches and spoiling the holidays of many tourists.

Punta Cana Seaweed problem 2022: Everything You Need to Know!!

Is Punta Cana facing a Sargassum Problem in 2022?

Punta Cana, along with other Caribbean countries, is currently facing a huge sargassum crisis. Sargassum is not a new thing for Punta Cana. Usually, every year, Punta Cana faces this problem in the summer season. However, this year, Punta Cana is experiencing the worst sargassum season since 2018.

Punta Cana first started to encounter the influx of sargassum on its beaches at the beginning of March 2022. Since then, month after month, the amount of sargassum washing up on the beaches of Punta Cana has been increasing continuously.

However, you should know that almost all the Caribbean counties are facing this problem. For more information about current sargassum conditions in Mexico, read the following posts:

How do Dominicans avoid Seaweed?
The majority of Punta Cana hotels, as well as the Dominican government, have initiated numerous large-scale measures to combat the seaweed problem.

Indeed, compared to many other Caribbean countries, numerous hotels in Punta Cana have made major investments in cutting-edge technology and are having greater success in tackling the seaweed problem.

This, however, is a temporary issue, and most days there will be no seaweed at all. Even when this occurs, beaches are often cleaned quickly. Also, not all of Punta Cana’s beaches have a seaweed problem.

Punta Cana Sargassum Forecasts 2022

Punta Cana is expected to encounter a massive influx of sargassum this year on its beaches. As it does every year, the concentration of sargassum washing up on beaches in Punta Cana is expected to increase from April to October.

Especially, Punta Cana is expected to receive the worst sargassum influx of this season in the months of July and August. And, as it does every year, it is predicted that sargassum season in Punta Cana will end at the end of September.

However, you must understand that the sargassum seaweed problem is a natural phenomenon. It originates in the sargasso sea but washed up on the shores of Caribbean countries due to ocean currents.

Sargassum level varies beach by beach, day by day, season by season, and place by place. Sargassum, in other words, is very difficult to track and very unpredictable.

However, if you want to know the current seaweed conditions you can check sargassummonitoring.com. This website shows the beaches that are currently affected by sargassum.

So, the best way to ensure a sargassum-free vacation in Punta Cana is to either stay on one of Punta Cana’s seaweed-free beaches, such as Bayahibe or Macao beach or to do some research and stay in hotels that are successfully tackling this issue.

How bad is the Seaweed Problem in Punta Cana?
Sargassum seaweed has been a major issue for nearly all Caribbean countries since 2015. As a result, the Dominican Republic is not the only country dealing with this problem.

When it comes to the sargassum crisis, 2018 was the worst year on record for all Caribbean countries, including the Dominican Republic.

This is referred to as the 2018 Great Sargassum Disaster, which had a huge impact on the Caribbean countries’ tourism industries.

Since then, the Dominican Republic’s government and most of Punta Cana’s hotels have taken numerous big initiatives to address this issue, as tourism is the country’s main source of income.

For instance, almost all hotels in Punta Cana employ dedicated staff that works hard to keep beaches sargassum-free on a daily basis.

Additionally, the majority of Punta Cana is protected by seaweed barriers designed to prevent sargassum from reaching the beaches.

Punta Cana Seaweed Season 2022

The reproduction of Sargassum seaweed accelerates significantly in the summer months and decreases significantly in the winter months.

That’s why you will see that Punta Cana is most affected by the seaweed problem in the summer months whereas this problem becomes quite rare in the winter months.

Punta Cana sees the largest influx of sargassum in the summer months (June to October), whereas the sargassum problem is fairly rare in the winter months (November to May).

Most affected Beaches by Sargassum in Punta Cana
Cabeza de Toro and Cap Cana are the most affected areas in Punta Cana by seaweed. However, as I previously stated, this is a transitory problem that varies from day to day, season to season, and place to place.

But, keep in mind that these areas are now protected by seaweed barriers and that the hotels in these areas have dedicated staff that works diligently day and night to keep the beaches clean.

Best Sargassum-free Beaches in Punta Cana
It is true that several beaches in Punta Cana have seaweed problems. However, there are still numerous places in Punta Cana that are completely sargassum-free, allowing you to enjoy Punta Cana’s world-famous gorgeous beaches without concern of seaweed.

Best Place to Stay in Punta Cana to enjoy Sargassum Free Vacation
Bayahibe resort town, as mentioned earlier is undoubtedly the best place to stay if you want to enjoy Dominican Republic’s world-famous pristine beaches without worrying about Seaweed. There is a nearly zero chance of seaweed in Bayahibe. However, apart from the seaweed, there are many good reasons to choose Bayahibe over Punta Cana.

  3. Bayahibe’s beaches are more relaxed than Punta Cana’s, with fewer tourists and far fewer vendors trying to sell you souvenirs.

Is Sargassum Dangerous to Humans?
Sargassum seaweed is usually harmless to humans when it is on water. However, once it reaches the beach, it begins to rot. Sargassum decomposes into stinging thick layers on the surface of the water, depleting the oxygen in the water and destroying the marine life in the area.

This rotting seaweed’s huge hips detract from the beauty of pristine beaches, and its rotten egg odor makes water activities and swimming nearly impossible and extremely uncomfortable.

How to Check Current Seaweed conditions before planning a vacation to Punta Cana?
Sargassum is definitely a big concern for tourists planning a vacation to Punta Cana. That is why, prior to planning your vacation, it is important to do proper research on the sargassum conditions at the beach or hotel you intend to visit.

Mexico : Norma Muñoz: “La gente no está informada de los efectos del sargazo, dice que las afectaciones las mandó Dios”

La coordinadora del Centro Interdisciplinario de Investigaciones del Instituto Politécnico de México lidera una investigación sobre los efectos en la salud de la macroalga

Los pobladores de Punta Allen se mantienen ajenos al acontecer del mundo. El pueblo de pescadores de apenas 400 habitantes se ubica en el extremo sur de la Riviera Maya, en el Estado de Quintana Roo, escondido en la reserva de la biosfera de Sian Ka’an, México. Además del difícil acceso por la falta de caminos pavimentados, la localidad no tiene señal para celular, y cuenta con electricidad solo a ciertas horas del día. No hubo contagios de covid, pero tampoco tenían cómo saber que los mareos, cansancio, ardor en los pies y ojos que sufren algunos pescadores son los efectos de convivir con el sargazo que arriba a las playas cada vez en una mayor cantidad.

Se enteraron recientemente cuando un grupo de investigadores arribó al lugar. Norma Patricia Muñoz Sevilla, coordinadora del Centro Interdisciplinario de Investigaciones y Estudios sobre Medio Ambiente y Desarrollo del Instituto Politécnico Nacional de México y su equipo los entrevistaron como parte de los estudios que hacen sobre el impacto ambiental del sargazo y sus efectos en la salud pública. “La gente no está informada y dice que las afectaciones que tiene las mandó Dios”, dice Muñoz.

El fenómeno también ha destruido sus bienes. “Hay un efecto corrosivo de los gases (ácido sulfhídrico, amoniaco y metano) que ha averiado sus aparatos electrónicos, refrigeradores, televisiones y teléfonos”, advierte. Tras más de 150 entrevistas a lo largo de la costa del Estado, no tiene dudas sobre los efectos de esa marea parda en la salud de la población, sobre todo de quienes tienen contacto directo con ella. “Ya no es que creamos que los está afectando, es así”, dice en entrevista con América Futura.

El sargazo es una macroalga cuya proliferación comenzó a sentirse en 2011 llegó en el Caribe mexicano, el extremo este de la península de Yucatán. Desde 2015 no ha dejado de arribar. Según la Secretaría de Ecología y Medio Ambiente de Quintana Roo, llegan unas 200.000 toneladas al año, con impactos negativos para el ambiente, las playas y el turismo. “Es un problema económico, ambiental y también de salud pública”, afirma Muñoz Sevilla.

Pregunta. ¿Cómo llega el sargazo al Caribe mexicano de manera creciente?

Respuesta. Es una especie viva que se reproduce en su camino y se nutre en el océano Atlántico, en la costa oeste de África, luego llega a la costa este de Sudamérica y posteriormente al Caribe. Cuando llega a la desembocadura de los grandes ríos, como el Congo, Amazonas y Orinoco, se nutre tremendamente y se duplica. En 10 días, un metro cúbico de sargazo puede convertirse en seis metros cúbicos.

P: ¿Qué relación tiene con el cambio climático?

R: Los modelos conceptuales de cómo se mueve y por qué, nos indican que la superficie del mar ha subido su temperatura. Las corrientes marinas han sufrido cambios en sus direcciones y movimientos en virtud de la contaminación de la masa de agua en el océano. Los vientos tienen una afectación importante también. Todo esto ha logrado que el sargazo se desprenda, se derive hacia el sur del océano Atlántico, pasando el Ecuador.

P: ¿Cómo empiezan a investigar los efectos en la salud?

R: Recientemente cinco países del Caribe ganamos un proyecto para establecer estaciones fijas para monitorear la calidad del aire y poder definir cuáles son las concentraciones de gases que el sargazo provoca. La isla de La Martinica lideró el proyecto, y nos otorgó todos los equipos que instalamos en Quintana Roo en septiembre. Este año también hicimos encuestas y entrevistas a lo largo de la costa con la gente que trabaja en quitarlo.

P: ¿En dónde colocaron los equipos?

R: Abarcamos desde Cancún hasta la frontera con Belice, se instalaron 12 equipos a lo largo de 700 kilómetros.

P: ¿Cuál es la experiencia de la Martinica en este tema?

R: Desde hace cinco años están trabajando con un semáforo que determina en tiempo real la concentración de gases, y cada día envían un boletín informando a su población sobre la calidad del aire para que no se acerquen. Es a lo que aspiramos hacer en el país.

P: ¿A quiénes entrevistaron?

R: Hicimos más de 150 entrevistas desde el sur hasta el norte del Estado, y les preguntamos cuáles eran sus padecimientos. Los sargaceros trabajan para los hoteles o el Gobierno en la orilla de la playa, ocho horas al día, sin protección. Pero no hay forma de que saquen el sargazo de manera constante por lo que se descompone y emite gases a la atmósfera.

P: ¿Qué tipo de gases emanan del sargazo?

R: Ácido sulfhídrico, amoniaco y metano. Cuando llega a la playa deja de ser un recurso natural y se descompone, se convierte en un residuo peligroso.

P: ¿Qué respondían las personas en las entrevistas?

R: Dicen que sienten que se les están quemando los pies, tienen problemas respiratorios, cambian de humor, problemas de la vista, algunos pierden el conocimiento por los gases. En la Martinica los trabajadores (que remueven el sargazo) llevan botas, equipo de protección, máscara, guantes, gorro. Aquí lo hacen sin zapatos, sin guantes, sin cubrebocas, a veces sin playera, porque hace calor.
