The north-east monsoon sets in through November, so the offshore returns to the south coast and the breaks from Ahangama to Hiriketiya start working again after five months off. The east coast is finished until May.
The season builds rather than arrives, and that is the thing to plan around. In a week, count on four days out of seven at Plantations in Midigama and three in Weligama bay, but those are averages over a month that changes as it goes: the first fortnight can still look like October, the last like December. Almost half of November is blown out at Plantations. If your dates can move inside the month, take the back half.
Prices have not caught up with the conditions yet, which is the argument for the month. The camps are reopening, the bay at Weligama holds a fraction of the boards it will carry at Christmas, and the sea is 29°C. For a first week, November costs less than the same week in February and the conditions are most of the way there.
Getting there is easy in a way Arugam Bay never is. Weligama is two and a half to three hours from the airport, the shortest transfer of the five villages, and the coast train to Ahangama and Midigama runs beside the water for its last stretch.
Where to stay follows the usual pattern. Weligama for learning, on sand at every tide. Midigama for the four reefs and quiet nights. Ahangama for The Rock and the evenings, with rooftops and cocktail bars facing the sunset. Hiriketiya, at the eastern end, for a cove that holds a wave when the open beaches close out, and a village of lanes and early nights. In November all four have room, which will not be true again until April.
