Nothing changes in the water between January and February. The north-east monsoon has blown since November and still reaches the south coast as an offshore, so the mornings stay clean and the count barely moves: five days out of seven at Plantations in Midigama, four in Weligama bay. What you lose is mostly afternoon wind, rarely a flat sea.
What changes is the calendar on land. The fortnight around New Year is the busiest of the southern year and February sits clear of it. It is still high season, rooms are priced like it and the good camps fill, but the Christmas visitors have gone home and the line-ups at dawn are easier to share than they were six weeks earlier.
That makes February a good month to base yourself in Midigama if you already surf. Four reefs break across two kilometres, all on the same swell and the same offshore, and most people stop at the first one, so a peak with a handful of people on it is realistic. Every one of the four has rock in the line-up, which is why a first trip still belongs at Weligama, fifteen minutes east along the coast, where the bay is sand and works at every tide.
The easy way down is the train. The line from Colombo runs beside the water for the last stretch into Ahangama and Midigama and costs a fraction of a transfer. By road, Weligama is two and a half to three hours from the airport. The sea is 28°C, the days are the same length as in July, and nothing in the water will tell February from January. Book the bed before the flight: February is still high season, and the camps that were full at New Year fill again.
