Sargassum at Pinel Island: What you need to know before you visit
Planning a trip to Pinel Island in Saint-Martin and concerned about sargassum seaweed? You’re not alone. In recent years, the presence of sargassum in the Caribbean has grown, with 2025 being a record-breaking year. Here’s what you need to know before you go, and why you shouldn’t let the seaweed stop you from enjoying this beautiful destination.
What is Sargassum?
Sargassum is a naturally occurring brown seaweed that floats on the ocean’s surface. While harmless, it can accumulate along Atlantic-facing shores and cause unpleasant odors when decomposing. In large quantities, it can also affect the aesthetics of beaches and shallow water.
Does Pinel Island have sargassum?
Yes, like many beaches on the Atlantic side of the Caribbean, Pinel Island can experience sargassum landings, especially during the spring and summer months. The east bay of Pinel is the most commonly affected area, depending on ocean currents and wind direction. Occasionally, a slight odor may be present, particularly on windy days.
What About the Launch Point?
Our launch point at Cul-de-Sac, where both kayaks and ferries depart, is often the most impacted area due to its proximity to the shore. The water may appear murky and filled with seaweed when you arrive. However, don’t be discouraged — once you paddle or sail away from the parking lot, the water clears up significantly, revealing the stunning turquoise waters Pinel Island is famous for.
Is It Safe to Visit Pinel Island During Sargassum Season?
Yes. Most of the time, the situation is completely manageable. The main beach at Pinel, where you’ll find Yellow Beach Restaurant and the Karibuni Restaurant, is typically cleaned regularly and remains welcoming for visitors. The north side of the island and the uninhabited areas may have more seaweed buildup, but they’re still accessible for adventurous travelers.
