Pero Lefts

West Sumba, Indonesia
🪸Sharp reef😮‍💨Hold-downs

Pero Lefts is a highly consistent left reef break on West Sumba's south coast that holds as big as it gets. The swell refracts around the headland creating big bowl sections with ample tube time, making this one of Sumba's most rewarding waves for experienced surfers. The wave's consistency means it's rarely flat during the April-October swell season, providing a reliable option when exploring this remote island.
