Planning a couples getaway, family vacation or honeymoon and looking for the best Caribbean beaches without seaweed?

If you’ve been reading about  sargassum seaweed problems in Mexico, Florida and the Caribbean, you might be wondering which Caribbean islands are not affected by seaweed and brown algae. 

It’s especially important to think about in 2025. The University of South Florida Oceanography lab reported a record-breaking sargassum seaweed bloom in the central Atlantic in December 2024.

It has the potential to migrate westward with ocean currents and cause a seaweed problem in the Caribbean in 2025.  

In order to help you plan your beach vacation, we’ve created a list of Caribbean beaches not affected by sargassum seaweed historically.  

I’ve been tracking sargassum seaweed in the Caribbean since 2019, visiting dozens of islands each year to find the best seaweed-free shores.

As a judge for the BeachAtlas Golden Beach Awards and The World’s 50 Best Beaches—and someone who has explored 60+ countries in search of perfection— I’m picky about what truly deserves to be called a beautiful beach.

For me, that means soft sand, clear water, and no seaweed.

In addition to firsthand visits, I also consult scientific resources like the University of South Florida’s oceanography laboratory for the latest sargassum forecasts.

While nature offers no guarantees, these beaches—chosen for their history of staying sargassum-free—are your best bet for Caribbean vacation in seaweed season.

Facts about Sargassum Seaweed 

The world’s largest sargassum seaweed bloom — known as the Great Atlantic Sargassum Belt — now stretches 8850-kilometres long from West Africa to the Caribbean Sea and the Gulf of Mexico, says Science magazine.

While there used to be an identifiable seaweed season of May to December, sargassum seaweed is arriving earlier, staying longer and the mats of seaweed are larger in size.

This increases the likelihood of encountering the unpleasant brown algae on your Caribbean vacation. 

The University of South Florida and NASA regularly produce a report titled Outlook of Sargassum blooms in the Caribbean Sea and Gulf of Mexico (known as (SaWS).

This report assesses the quantity of sargassum seaweed in the central Atlantic and tracks its movement and landings on beaches in Mexico, Florida and the Caribbean.   

It identified heavy influxes of sargassum in 2018, 2019, 2022 and 2023. 

Caribbean islands most affected by sargassum seaweed in the past include beaches in Barbados, Tobago, Guadeloupe, Dominican Republic and Martinique. 

Caribbean Sargassum Seaweed in 2025

However, it’s important to note that even on islands affected by an influx of sargassum algae there are often beaches with no seaweed on the same island.    

For example, in 2022, when mainland of Playa del Carmen, Mexico had a severe sargassum seaweed problem, the leeward beaches of Isla Mujeres and Cozumel were free of seaweed. 

And in Barbados, Carlisle Bay often has no issues with sargassum.  

While there’s no guarantee, if you’re planning a beach vacation and looking for Caribbean islands not affected by seaweed and Caribbean beaches without seaweed, here are some destinations to consider:

1.  Grand Anse  in St. Georges, Grenada

With its organic bean-to-bar chocolate, artisanal rum plantations and mountainous interior dotted with waterfalls, there’s lots to love about the Caribbean island of Grenada  without even considering its idyllic  beaches.

In Grenada, Grand Anse regularly tops the list of the world’s best beaches due to its crystal clear waters and its 2 kilometre long stretch of white sand dotted with palm trees.  

It’s also blessedly free of sargassum seaweed.

Even at the height of seaweed season, you’ll rarely see anything except a star fish in the water. There are lots of resorts to choose from on Grand Anse Beach, but here are my favourites:   

Check availability and prices at Spice Island Beach Resort, a luxury hotel on Grand Anse Beach, on Booking.com. 

Check availability and prices at Radisson Grenada Beach Resort, the best mid-range hotel on Grand Anse Beach, Grenada on Booking.com.   

Check availability and prices at the Siesta Hotel, a budget hotel near Grand Anse Beach, on Booking.com.

2. Morne Rouge Beach on Grenada 

This beautiful seaweed-free beach with turquoise blue waters is also on the island of Grenada.

Morne Rouge also known as BBC Beach is less well known than Grand Anse Beach but is also rarely affected by sargassum seaweed.

It’s especially popular with families as the waters are very calm for swimming. Morne Rouge is a great option if you’re looking for a family-friendly Caribbean beach without seaweed.

While there are several budget hotels and condos for rent overlooking Morne Rouge, the closest 4-star hotel is Mount Cinnamon Resort.

Considered one of the most beautiful beaches in the world, Grace Bay Beach features clear waters and powder soft sand. This long beach is protected by a barrier reef so is especially calm.

Grace Bay in Providenciales, Turks and Caicos is definitely a destination to consider if you’re looking for Caribbean beach without seaweed for a family, couples or group vacation.  

Although the Turks & Caicos participates in the Caribbean Development Bank, it’s technically situated north of the Caribbean and in the tropical Atlantic. However, the waters are as blue as the Caribbean! 

On the opposite coast, Long Bay Beach is known to receive some seaweed on its shores.  It’s more of a windswept beach with dramatic wave action and has its own unique beauty.

4. Druif Beach, Baby Beach and Palm Beach in Aruba, Dutch Caribbean  

The Dutch Caribbean island of Aruba is best known for its white sand beaches, luxury resorts and cooling trade winds.

In addition to being located outside the hurricane belt, its famous beaches such as Eagle Beach, Palm Beach, Druif Beach and Baby Beach also have the good fortune of being outside the sargassum seaweed belt.

So, if you’ve been spending the winter imagining yourself kicking back on a lounger, sipping a tropical cocktail at a beach bar and floating in idyllic Caribbean waters without any brown smelly seaweed to spoil the fantasy, then consider Aruba.

It’s one of the most reliable Caribbean islands without sargassum.

While there are several small, boutique-sized hotels in Aruba, here are two of our favourite large resorts on Palm Beach and Eagle Beach.

5. Playa Porto Mari on Curacao, Dutch Caribbean 

One of the most beautiful beaches in Curacao also happens to be one of the best Caribbean beaches without sargassum.  

Located on the west coast of the island of Curacao, Playa Porto Mari is a private beach which means there is an entrance fee. Check the Porto Mari website for hour and prices.

Although there have been issues with foul-smelling sargassum seaweed in Jamaica (such as Fort Clarence Beach near Kingston) the beaches in Negril have generally been free of sargassum seaweed. 

🌟 Note: There is a difference between seagrass (which grows on the ocean bottom) and sargassum seaweed, a free-floating mass of seaweed that accumulates on the ocean’s surface.

7.  Beaches in Antigua & Barbuda

The luxurious St. James Club on Antigua’s eastern windward side had to shut down for three months in 2019 due to a massive sargassum influx. However, many other beaches in Antigua often remain seaweed-free.

Located on the southern tip of Antigua, Curtain Bluff Resort’s two beaches receive very little seaweed. The boutique resort features 72 rooms and all-inclusive dining. Guests can enjoy tennis, squash, sailing, guided snorkelling and sea kayaking. 

Sargassum on Antigua Beaches in 2023

Dickenson Bay, Jolly Beach and other beautiful beaches in Antigua on the west coast of Antigua have historically not received an influx of sargassum.

But due to wind currents and other factors, considerable sargassum and sea grass has been reported on some stretches of Dickenson Beach,  Jolly Beach and others in March 2023.

This included Sandals Grande Antigua Resort & Spa.

It’s worth looking into Darkwood, Carlisle Bay and FFryes beaches. They’re beaches without sargassum historically.

8. Playa Norte on Isla Mujeres and Best Beaches Without Seaweed in Mexico 

If you have your heart set on visiting resorts on Mexico’s Caribbean coast, it’s still possible to find beaches with no sargassum seaweed along this vast coastline.

While exposed eastern shores are most likely to get hit by surges of sargassum, some beaches in Mexico have no sargassum.

This includes Playa Norte on Isla Mujeres, Quintana Roo (Bacalar inland) and Cozumel’s western shore. They’re generally seaweed-free. However, much depends on winds and ocean currents.

It’s also worth considering the beaches on Mexico’s Pacific Coast if you’re looking for beaches without seaweed. While the waters are darker blue than that those in the Caribbean, they aren’t affected by the Atlantic Ocean’s sargassum seaweed.

There’s no sargassum seaweed on Mexico’s Pacific Coast beaches.

Some of the prettiest Mexican beaches are located on the the country’s Pacific Coast.

Top beaches in Mexico without seaweed include Carrizalillo Beach, Punta Mita, Mismaloya and Bucerias (near Puerto Vallarta) and Santa Cruz beach (Huatulco). 

🌟 Note: Red tide is a different phenomenon than sargasso seaweed and all beaches can temporarily be affected by red tide algae.  

9. Little Bay Beach, St. Maarten

This little dual nation island (one side is Dutch, and the other side is French,) has 37 lovely beaches dotted around its 34 square miles. It occasionally has problems with sargassum, but mostly on the east coast.

If you’re looking for a beach without seaweed in St. Maarten, Little Bay Beach, on the southern side and minutes from the capital of Philipsburg is a good bet.

It’s rarely affected by sargassum seaweed as it’s on its own peninsula and protected by rocky outcroppings on either side.

🌟 Insider Tip: There is excellent snorkeling right off the Divi pier. You are sure to spot scads of tropical fish on their house reef. If you’re lucky you might even see spotted rays and sea turtles! 

10. Bayahibe Beach in Dominican Republic

While Bavaro Beach in Punta Cana, Dominican Republic is known to receive large amounts of seaweed, the southern coast beaches often have no seaweed at all.  

Bayahibe beach, 30 minutes from La Romana, is a good option for beaches in Dominican Republic with no seaweed.

It has powdery white sand dotted with lofty palm trees and crystal clear waters. It’s the perfect place to enjoy a quintessential tropical beach day in the Caribbean.

Forecast 2025 for Sargassum Seaweed in the Caribbean 

According to the University of South Florida oceanography laboratory, there is large sargasso seaweed mat in the central Atlantic. In November 2024 it was the largest accumulation of sargassum ever recorded for the month.

This record amount of sargassum suggests that there is a high risk of major blooms of seaweed in the Caribbean in 2025. As of February 2025, it has already begun to land on beaches in the eastern Caribbean.

The western Caribbean Sea could expect to begin to see sargassum seaweed blooms in March 2025.

However the potential impact on Caribbean beaches depends on ocean currents. The amount of seaweed landing on coastal beaches in the Caribbean and the Gulf of Mexico could be lower than expected.

And note that it’s often to possible to find seaweed-free beaches even during sargassum season.

Even at the peak of the seaweed problem in Cancun, it was possible to find seaweed-free beaches to enjoy.

Resources for Tracking Caribbean Sargassum in 2025 and Seaweed Forecasts for 2025

Global News reports that 25 per cent of Canadians book Christmas travel more than three months in advance.

So, waiting for sargassum reports and booking a last-minute trip might not be practical.  

There are three main ways to get a general outlook of current sargassum seaweed bloom conditions and future bloom probability for the Caribbean Sea.

They include:

1. Checking the SEAS Program for updated information about when and where sargassum is going to be. Click to access the Seas Forecast. to see real time seaweed forecast for the next 8 days. 
2. Monitoring Caribbean seaweed blooms on the University of South Florida’s satellite-based Sargassum Watch System (SaWS).
3. For the Caribbean coast of Mexico from Cancun to Tulum, visit the Red de Monitoreo del Sargazo Cancun Facebook page. It has weekly updates on seaweed conditions.    

Remember that seaweed predictions are based on a complex number of factors. These include historical levels, patterns, ocean temperatures, currents and more.

Predictions are probabilities only. So, you can’t count on them to be 100% accurate.
