December is when Sri Lanka’s south and west coasts come into season. The south-west monsoon is long gone, the north-east monsoon is soaking the other side of the island, and the beaches from Bentota to Tangalle start their best stretch of the year. It is also the busiest month for visitors, with Christmas, New Year and the start of the Sri Pada pilgrimage all falling in the last fortnight.
So December is a very good month, as long as you go to the right coast and book early.
Is December a good time to visit?
Go if you want the south and west coasts, the whale-watching season off Mirissa, or the start of the pilgrim season on Sri Pada. Christmas on the beach is a real option here.
Think twice if your heart is set on the east coast or the north. Trincomalee, Pasikuda, Arugam Bay and Jaffna are in their wet season. And if you hate crowds and high prices, the shoulder months either side are calmer.
The weather, region by region
- South and west coasts (Colombo, Bentota, Hikkaduwa, Galle, Unawatuna, Mirissa, Tangalle). Drying out as the north-east monsoon takes the rain to the other side of the island, at the start of their main season, which runs to March. Sri Lanka Tourism says Mirissa’s beaches are at their best from November to April.
- East coast and north (Trincomalee, Arugam Bay, Jaffna). The north-east monsoon brings the rain from December to February, and October to January is the east coast’s wet season in the long-term averages. Not the month for these beaches.
- Hill country. Cooler all year and cold at night in Nuwara Eliya. The western hills, around Hatton and Nuwara Eliya, are drying out. The eastern side, around Ella and Badulla, catches the north-east monsoon: October to January are Badulla’s wettest months. Walk early, before the cloud comes in.
- Cultural Triangle (Anuradhapura, Sigiriya, Polonnaruwa, Dambulla). Still in its wetter season, which runs from October to December, so expect some heavy showers between dry spells. It is very doable: start early and keep afternoons flexible.
Our guide to the best time to visit Sri Lanka has the year-round picture, and travelling in the monsoon covers what the rain means on the ground.
What’s in season
- Whale watching from Mirissa. Sri Lanka Tourism gives the season off the south coast as November to April, so December is well inside it. Boats leave the harbour early in the morning. Our Mirissa whale-watching guide explains how to choose a boat that keeps to the rules.
- Surf on the south coast. The south and south-west coast, from Hikkaduwa through Weligama to Hiriketiya, is in season from about November to March. Surf schools report January and February as the peak, and line-ups get busy around Christmas. See south coast or Arugam Bay for surfing.
- Sri Pada (Adam’s Peak). The pilgrimage season traditionally opens on Unduvap Poya, which falls on Wednesday 23 December 2026, and runs to Vesak in May. In season the path is lit and the summit busy at dawn. Our Sri Pada guide has the details.
- Galle Fort, Colombo and the south-west. Dry, warm weather makes it a good month for walking the ramparts at Galle Fort or exploring Colombo.
Christmas, New Year and Poya
- Unduvap Poya, Wednesday 23 December 2026. A public holiday and a dry day: liquor shops and bars close, and meat isn’t sold. Many people go to the temple.
- Christmas Day. A public holiday. It is also a dry day on the Excise Department’s list, but approved tourist hotels are allowed to serve their own guests at Christmas and New Year.
- New Year’s Eve. Book rooms and any special dinner well ahead for the fortnight from Christmas to New Year.
Our festival and Poya calendar lists every holiday through to September 2027.
Crowds and prices
December and January are the busiest months of the year. Sri Lanka Tourism’s figures for 2025 show each of them with more than 250,000 visitor arrivals, compared with fewer than 140,000 in May and June. Expect fuller hotels and higher rates on the south and west coasts, especially from Christmas to New Year.
- Book early for the Christmas and New Year fortnight: rooms, drivers and popular restaurants all fill up.
- Book trains as soon as seats open. Reserved seats on the scenic hill-country trains go on sale 30 days ahead on the Sri Lanka Railways seat reservation site and can sell out in minutes. Check the travel update on our train travel guide for which sections of the line are open.
- Go early in the day to the big sights, before the heat.
A December route
A natural December trip runs from the Cultural Triangle and Kandy into the hill country, then down to the south coast for the second week, ending on the beach for Christmas or New Year. Our 10 days of beaches and mountains and 14 days in Sri Lanka itineraries both follow the season. Leave the east coast for a trip between May and September.
