January sits in the middle of the south coast season. The north-east monsoon crosses the island and reaches Weligama, Midigama and Ahangama as an offshore, so the reefs and beach breaks along that stretch hold their shape through the morning and often the day.
It is the driest and the busiest month on that coast, and the two go together: this is European winter, the camps are full and Weligama bay has a lot of boards on it. The east coast is shut, so nothing to consider there until May. The water is at 28°C and boardshorts are the whole kit, which is most of why people fly eleven hours for it.
