There is no specific time of year for seaweed to appear in Punta Cana, as it is largely dependent on the water temperature, the weather, and the algae blooms. Seaweed can appear at any time of year, from the hot summer months to the cooler winter months. The most common times they occur are during the rainy seasons, which include September to December, and May to June.

What Causes Seaweed in Punta Cana?

The primary cause of seaweed in Punta Cana is the increasing ocean temperatures, which are changing due to global warming. Plus, rising water temperatures increase the amount of carbon in the ocean. This leads to the development of algae blooms, and when the algae blooms occur in droves, it leads to the development of seaweed. The nutrient pollution from fertilizers, sewage, and industrial runoff are also contributing factors to creating the optimal conditions for seaweed in the region.

What Measures Are Being Taken to Solve the Seaweed Problem?

Since 2017, when the seaweed levels in Punta Cana rose to noticeable levels for the first time, the tourism and environmental officials in the region have been working to address the issue. Several national and regional projects currently monitor seaweed levels and take necessary actions to prevent or decrease algae appearance. Meanwhile, hotels and resorts in the area are implementing their own measures to manage seaweed on their shorelines.

These measures often involved the use of machinery to clean the beaches, as well as the implementation of techniques to reduce the seaweed on the coastline.

What Can Tourists and Residents Expect?

Since seaweed levels vary throughout the year, predicting their appearance is impossible, and the measures to reduce them remain uncertain. However, visitors to Punta Cana should expect that some seaweed will be present on the beaches at some point.

While this may reduce the appeal of the beaches for some, the water and other onshore activities remain unaffected. Additionally, efforts ensure that the seaweed does not impact the beaches for too long.

What Can Be Done to Limit Seaweed in Punta Cana?

Although national and regional projects have successfully reduced seaweed levels, additional measures can help limit their appearance. Residents, tourists, and the local tourism industry can take steps to clean up the beaches and prevent further seaweed growth.

For example, tourists and locals must avoid throwing litter into the water or leaving trash on the shores. Additionally, beach visitors can adopt eco-friendly travel habits, such as walking or biking instead of driving. They should also refrain from using single-use plastics.
