March Magic: Why This Is Peak Season for Underwater Adventures
Crystal -clear waters, calm seas, and marine life in abundance
There is a brief window each year when the waters surrounding Cousine Island transform into something truly extraordinary.
March marks the peak of this magical period—when underwater visibility reaches its clearest, the seas are at their calmest, and the marine life of the Seychelles reveals itself in all its magnificent diversity.
For those who dream of slipping beneath the surface of the Indian Ocean and discovering a world few ever witness, March on Cousine Island offers an experience that simply cannot be replicated at any other time of year. Our Eco Calendar rates March as having "very clear" underwater visibility, the highest rating of any month.
The Science of
Crystal Clear Water
What makes March so special? The answer lies in the confluence of weather patterns unique to the Seychelles.
As the northwest monsoon winds settle and before the southeast trade winds fully establish themselves, the waters around Cousine Island enter a period of remarkable stillness. Sediment settles, plankton disperses evenly, and the result is visibility that can extend beyond thirty metres in optimal conditions.
The seas themselves are calm, a welcome respite from the livelier conditions that characterize other months. Water temperatures hover between 26 and 31 degrees Celsius, warm enough to explore comfortably in a shorty wetsuit or even just swimwear, yet refreshing enough to spend hours in the water without fatigue.
Snorkelling
The Gateway to Another World
For many guests, snorkelling provides the perfect introduction to the underwater realm.
Cousine Island's fringing reef begins just metres from the shore, meaning you can step from your private villa and be floating above coral gardens within minutes.
The house reef teems with life throughout the year, but March's exceptional clarity transforms the experience. Parrotfish in electric blues and greens graze on coral. Schools of surgeonfish move in synchronized formations. Butterflyfish dart between anemones, and if you remain still and patient, you may find yourself eye-to-eye with an inquisitive octopus or a graceful hawksbill turtle gliding past.
One of the most treasured snorkelling experiences is the guided excursion to the back of the island, a location inaccessible by beach and reachable only by boat. Here, untouched coral formations host marine species rarely encountered elsewhere, and the sense of exploration is palpable.
Scuba Diving
Deeper into the Blue
For certified divers, March opens doors to some of the most spectacular dive sites in the inner Seychelles.
Our preferred partners offers personalized excursions to both the house reef and longer-range locations where the big encounters happen.
The marine biodiversity of these waters is staggering. Reef sharks patrol the deeper channels. Manta rays sweep through the blue with effortless grace. Eagle rays ripple along sandy bottoms. For those fortunate enough to time their visit with the tail end of whale shark season, encounters with the world's largest fish remain possible into early March.
Our professional dive team tailors every underwater experience to your skill level and interests. Whether you are seeking the thrill of drift diving along granite formations or prefer a meditative exploration of coral gardens, we create an itinerary designed around you.
Turtle Hatchlings
Above and Beyond
March offers a remarkable bonus beyond underwater adventures. This is the final month of the Hawksbill turtle hatchling season, when tiny turtles emerge from their nests and make their extraordinary first journey to the sea. Guests have a high chance of witnessing this ancient spectacle, a reminder that Cousine Island's conservation work has helped protect over 200,000 hatchlings across three decades.
