Seychelles in December: Weather, Crowds & What to Expect

Mahé - Victoria, Beau Vallon and West Coast

December remains hot and humid, with frequent short, heavy showers interrupting long sunny spells - sea temperatures are at their warmest near 29-30°C. Holiday crowds swell, particularly around Beau Vallon and Victoria, and New Year’s festivities bring extra demand for rooms and boat charters. If you plan diving or shelling trips, book early and carry reef-safe sun protection, a hat and quick-dry clothing; expect lively markets and a very summery island atmosphere.

Mahé Highlands - Morne Seychellois and upland trails

December often brings warm, humid conditions lower down and cloud-filled mornings in the highlands with regular tropical showers through the day. The pathways are sodden and waterfalls run strongly, offering dramatic scenes for nature photographers, but plan for slippery, heavy going. If you are aiming for clear summit views, aim for brief post-rain windows and carry warm, waterproof layers and a headlamp for early starts or late returns.

Praslin & La Digue - Inner granitic islands and beaches

December is hot, very humid and punctuated by tropical downpours that refresh the forests and beaches; holiday crowds increase around popular beaches and ferries fill fast. La Digue’s lanes bustle with visitors cycling to Anse Source d’Argent and boat charters book out for New Year’s; carry reef-safe sunscreen and a compact umbrella. Mornings are often the most reliable for beach time and diving trips, while afternoons can bring dramatic showers and thunder.

Outer Islands & Atolls - Aldabra, Farquhar, Alphonse and more remote coralline islands

December is typically very warm with intermittent heavy downpours and strong sun between storms; atoll flats can be blisteringly hot when wind drops, and freshwater is precious on many outer islands. Holiday-season logistics tighten for operators, and access can be limited during brief but disruptive squalls, so confirm bookings and emergency contacts. For wildlife enthusiasts, winter months provide active seabird and turtle behaviour windows - bring durable sun protection and conservative travel timelines.
