Pero Lefts
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.

Frequently Asked Questions
What kind of wave is Pero Lefts?
Pero Lefts is a reef break in West Sumba, Indonesia, that mostly breaks left.
What swell works best at Pero Lefts?
Pero Lefts picks up swell from the SSW round to the WSW, and it's best when it's coming straight out of the SW. That's a tight window, so it needs the swell direction to line up. It starts working at around 1.2m and handles up to about 3.7m, with the sweet spot around 2.3 to 3.1m. Period matters too: aim for 16s or longer, as anything under 12s tends to be weak. These are the numbers our scoring uses, so treat them as a guide rather than a promise.
What wind is offshore at Pero Lefts?
A NNE wind is dead offshore at Pero Lefts, and anything from the N round to the NE keeps it clean. The morning is typically the best window, roughly 6am to midday. Light winds from other directions can still be fine; strong offshores can make it hard to get into waves.
What tide is best at Pero Lefts?
Pero Lefts is at its best around mid tide, roughly 0.5m to 1.5m on the local chart.
When is the best time of year to surf Pero Lefts?
The most reliable run of swell at Pero Lefts comes Apr to Oct. There's a second window in Nov to Mar too. Best Apr-Oct (dry season, SE trades offshore). Swells year-round but wet season brings onshore winds.
How cold is the water at Pero Lefts?
