Clean up efforts help but some seaweed is unavoidable.
In this comprehensive guide, we’ll cover what sargassum is, why it reaches South Florida beaches, how much we can expect in Fort Lauderdale this year, what the impacts are, and what is being done for clean up and management.
What is Sargassum
Sargassum is a type of brown seaweed that is found in the ocean. It is a floating algae that can grow in large masses and is often referred to as a “sea weed mat”. Sargassum is unique because it does not attach to the ocean floor or rocks like other seaweeds do.
Instead, it floats freely on the surface of the water.
Definition and Key Facts
Sargassum is a genus of brown algae that belongs to the family Sargassaceae. It is named after the Sargasso Sea, an area in the North Atlantic Ocean where large amounts of Sargassum can be found. The seaweed is characterized by its long, leafy fronds and small air bladders that help it stay afloat.
One interesting fact about Sargassum is that it plays a crucial role in providing habitat and food for a wide range of marine species. Many fish, turtles, and crustaceans rely on Sargassum mats for shelter and protection.
The seaweed also serves as a nursery for baby sea turtles, providing them with a safe place to grow and develop.
Native Habitat and Ecosystem Services
Sargassum is an important part of marine ecosystems, particularly in the Sargasso Sea and other tropical and subtropical regions. It provides several ecosystem services, including oxygen production, carbon sequestration, and nutrient cycling.
The seaweed also helps to stabilize coastlines by reducing erosion and acting as a natural barrier against waves and storms.
While Sargassum is native to the Atlantic Ocean, in recent years, there has been a significant increase in its presence in other parts of the world, including the Caribbean and Gulf of Mexico. This increase has been attributed to factors such as climate change, ocean currents, and nutrient pollution.

Causes of Sargassum Influxes in Florida
Sargassum influxes in Florida, including Fort Lauderdale, have become a noticeable phenomenon in recent years. These influxes can have significant impacts on coastal communities, tourism, and the local ecosystem.
Understanding the causes behind these influxes is crucial for developing effective management strategies. Two main factors contribute to the increase in Sargassum in Florida: natural ocean currents and nutrient pollution.
Natural Ocean Currents
Natural ocean currents play a significant role in the distribution of Sargassum. The Sargassum seaweed originates in the Sargasso Sea, a region in the North Atlantic Ocean. It is then carried by the North Equatorial Current and the Gulf Stream, which transport it towards the Florida coast.
The convergence of these currents near the eastern coast of Florida, including Fort Lauderdale, leads to the accumulation of Sargassum on the beaches.
The intensity and frequency of these ocean currents can vary from year to year, impacting the amount of Sargassum that reaches the shores. Climate patterns such as El Niño or La Niña can influence the strength and direction of the currents, potentially leading to fluctuations in the Sargassum influxes.
Monitoring these patterns can help predict and prepare for potential influxes in the future.
Nutrient Pollution
Nutrient pollution, specifically excess nutrients such as nitrogen and phosphorus, can contribute to the growth and proliferation of Sargassum. These nutrients can come from various sources, including agricultural runoff, sewage, and fertilizers.
When these nutrients enter the coastal waters, they act as fertilizers for Sargassum, promoting its rapid growth.
Florida’s coastal regions, including Fort Lauderdale, are susceptible to nutrient pollution due to their proximity to urban areas and agricultural activities. The high nutrient levels in the water create favorable conditions for Sargassum to thrive and form large mats along the coastline.
Efforts to reduce nutrient pollution, such as improved wastewater treatment and responsible agricultural practices, can help mitigate the Sargassum influxes in the future.
It is important to note that while natural ocean currents and nutrient pollution are major contributing factors, other variables can also influence the occurrence and severity of Sargassum influxes. These factors can include changes in water temperature, wind patterns, and the availability of other essential nutrients.
Ongoing research and monitoring are essential to better understand and manage these influxes for the benefit of coastal communities and ecosystems.
Sargassum Outlook for 2023 in Fort Lauderdale
Seasonal Projections Based on Prior Years
Fort Lauderdale residents and visitors have become familiar with the annual influx of sargassum seaweed on the city’s beaches. While it is difficult to predict with absolute certainty, based on prior years’ data and trends, it is expected that Fort Lauderdale will continue to experience sargassum blooms in 2023.
According to studies conducted by marine biologists, the amount of sargassum washed up on the shores of Fort Lauderdale can vary from year to year. Factors such as ocean currents, water temperature, and nutrient levels play a significant role in determining the severity of the blooms.
Sargassum tends to be more prevalent during the summer months, with an increase in seaweed sightings typically starting in May and continuing through September. However, it’s important to note that the timing and intensity of the blooms can vary from year to year.
While sargassum can be an inconvenience for beachgoers, it’s important to remember that it plays a crucial role in marine ecosystems. The seaweed provides habitat and food for various marine species, including sea turtles and fish.
For the most up-to-date information on sargassum sightings in Fort Lauderdale, residents and visitors can check the city’s official website or consult local news outlets.
Peak Times and Duration
Based on historical data, the peak times for sargassum blooms in Fort Lauderdale typically occur during the summer months, with July and August being the most affected. During these months, beachgoers may notice larger accumulations of sargassum on the shorelines.
The duration of sargassum blooms can vary, but they usually last for several weeks to a couple of months. It is important to note that sargassum does not continuously wash ashore throughout the entire season.
There may be periods of time when the seaweed is less prevalent, followed by increased activity.
Local authorities and beach maintenance crews are typically proactive in cleaning up the sargassum to ensure that the beaches remain clean and enjoyable for visitors. Efforts are made to remove the seaweed promptly and efficiently, although it can be a challenging task given the sheer volume of sargassum that can accumulate.
It’s worth mentioning that while sargassum blooms may be an inconvenience for beachgoers, they can also provide unique opportunities for photographers and nature enthusiasts.
