Sri Lanka in January
Peak season on the south coast
January is one of the best months to be on the south coast: dry days, flat calm mornings and whales off Mirissa. The trade-off is that everyone else knows it, so the first two weeks are the busiest and most expensive of the year.

Local tip
✦ If your dates are flexible, arrive after 10 January. The Christmas–New Year crowd clears out and room rates usually ease off a little.
