Sri Lanka in December
December weather, region by region
The north-east monsoon is winding down over the east and north, so those coasts stay damp. But the south, west and central hills are dry and bright: coastal temperatures sit around 28–31°C, while the hill country around Nuwara Eliya is cooler and fresh — pack a layer for early mornings.
Where to go this month
Weight your route to the south and west: Galle Fort, the beaches at Mirissa and Unawatuna, and blue-whale season off the south coast. Inland, Sigiriya, Kandy and the tea country are all at their best. A private driver-guide links them at your own pace — see a ready-made 10-day itinerary for the classic loop.
Planning around Christmas peak
Because December is the busiest month, flights from the UK and the best south-coast hotels sell out well ahead. Reserve your driver and rooms early, and expect higher rates over Christmas and New Year. For a quieter, cheaper alternative with similar weather, look at the shoulder months either side.
Frequently asked questions
Is December a good time to visit Sri Lanka?
Yes — December is one of the best months for the south and west coasts and the Cultural Triangle. It's dry, sunny and warm, which is why it's peak season and lines up perfectly with UK Christmas and New Year breaks.
What's the weather like in Sri Lanka in December?
On the south and west coasts expect warm, largely dry days around 28–31°C. The east coast is in its wetter season, so December trips are best planned around the south, west and hills rather than Trincomalee or Arugam Bay.
Is Sri Lanka busy at Christmas and New Year?
Yes — late December is the busiest and priciest window, especially the south-coast beaches. Flights from the UK and the best hotels book up months ahead, so reserve your driver and rooms early.
Where should I go in Sri Lanka in December?
Focus on the south and west: Galle, Mirissa and Unawatuna for beaches and whales, the Cultural Triangle for Sigiriya and the ancient cities, and the hill country around Kandy, Nuwara Eliya and Ella. Skip the east coast this month.
