Frequently Asked Questions

What kind of wave is Walo Hiu?

Walo Hiu is a reef break in South Nias, Indonesia, that mostly breaks left.

What swell works best at Walo Hiu?

Walo Hiu picks up swell from the S round to the WSW, and it's best when it's coming straight out of the SW. It starts working at around 1.5m and handles up to about 3.7m, with the sweet spot around 2.5 to 3.2m. 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 Walo Hiu?

A NE wind is dead offshore at Walo Hiu, and anything from the NNE round to the ENE 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.

The water at Walo Hiu averages around 28°C, so boardshorts or a rashguard will do. It shifts a few degrees through the year, so check the season before you pack.
