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.

The Pero Lefts profile favors mid tide, ideally between 0.5m and 1.5m on the local tide chart. Compare this preference with the forecast tide and local conditions before choosing a session.
The Pero Lefts profile uses wind from NNE (22°) as its preferred direction, with an offshore range of 352° to 52°. Wind speed matters too: light winds outside that range can still produce surfable conditions, while strong offshore winds can make takeoffs difficult.
The Pero Lefts scoring profile favors swell from SW (200° to 240°), a swell-height range of 1.2m to 3.7m, and a reference period of 16s. These are model inputs, not guaranteed breaking-wave heights or a promise that the surf will suit every ability.
The main season at Pero Lefts is Apr-Oct. A secondary window runs Nov, Dec, Jan, Feb, Mar. Best Apr-Oct (dry season, SE trades offshore). Swells year-round but wet season brings onshore winds.
