Wondering if you should book your ticket to Guadeloupe because you've heard about sargassum 🌱?
Or maybe you've already booked, and you're worried about whether there will be any during your stay and whether this will spoil your vacation?
No need to panic. Yes, sargassum exists, but no, they won't turn your trip into a nightmare 😊 Guadeloupe remains a dream destination, even when they're around.
👉 The key is to understand when they can appear, where they end up, and above all how to avoid them. And the good news is that there are always sargassum-free beaches, whatever the time of year.
What is sargassum?
Sargassum is a floating algae that has always existed naturally in the Atlantic. They play an essential role in biodiversity, serving as nurseries for numerous marine species.
In recent years, their arrival has become more frequent on Caribbean coasts, mainly because of :
- rising ocean temperatures
- and the intensification of agriculture in the Amazon, which enriches the ocean with nutrients that promote their growth.
In short, it's a natural phenomenon amplified by environmental changes.
A bit like brown algae in Brittany or jellyfish on the Côte d'Azur: we know they may appear, but no one can predict exactly when or where.
👉 Good news: when they run aground, local authorities get organized. Beaches are regularly cleaned and devices are installed to limit their impact.
When can sargassum appear in Guadeloupe?
The sargassum season varies from one year to the next, but it is generally observed in the following areas between August and September, sometimes a little before or a little after, depending on the current.
Key facts about Sargassum seasonality
- During the high tourist season (November to April), sargassum is very rare.
- Even in summer, not all beaches are concerned, far from it.
- The phenomenon is seasonal, irregular and localized.

How do you get around sargassum when it's there?
That's where it gets reassuring: there's still untouched areas, even at the height of the season.
