December brings the warm, wet northwest-monsoon season into full swing, with rainfall climbing toward the December-January peak. It averages around 30°C/25°C with frequent, often heavy tropical downpours.
The rain is the trade-off for the season's lush greenery and calm seas — the gentle northwest winds keep the water settled for diving and snorkelling between showers. Seaweed tends to drift onto northwest-facing beaches in this window.

Seychelles in December — Full Picture
December brings the warm, wet northwest-monsoon season into full swing, with rainfall climbing toward the December-January peak. It averages around 30°C/25°C with frequent, often heavy tropical downpours.
The rain is the trade-off for the season's lush greenery and calm seas — the gentle northwest winds keep the water settled for diving and snorkelling between showers. Seaweed tends to drift onto northwest-facing beaches in this window.
December is dominated by the Christmas and New Year holidays, the busiest and most expensive period of the year: flights spike and the better resorts and guesthouses book out months ahead. Reserve everything early if you travel now.
Build flexibility into beach plans and keep an indoor or town option (Victoria, the Takamaka distillery) for the heaviest rain. Outside the holiday spike, the green season is quieter, but the rain is a genuine factor to plan around.
What to Wear & What to Pack
Warm, wet northwest-monsoon season with heavy rain returning — around 30°C/25°C. Lightweight clothing, swimwear, a light rain jacket or umbrella, and reef-safe SPF 50+. Showers are often heavy but brief.
