Frequently Asked Questions

What kind of wave is Nungas?

Nungas is a reef break in East Sumbawa, Indonesia, that mostly breaks left.

What swell works best at Nungas?

Nungas picks up swell from the SSW round to the SW, 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 3m, with the sweet spot around 2 to 2.6m. Period matters too: aim for 14s or longer, as anything under 10s 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 Nungas?

An E wind is dead offshore at Nungas, and anything from the ENE round to the ESE 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 Nungas?

Nungas 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 Nungas?

The most reliable run of swell at Nungas 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 Nungas?

The water at Nungas 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.

Is Nungas good for beginners?

Not really. It's rated 7/10 for difficulty and suits experienced surfers. Expect a moderate crowd (4/10) when it's on. Things to watch for: sharp, shallow reef (booties help) and a long walk or paddle in.

How do I get to Nungas?

The nearest airport on our list is BMU, then it's roughly a 30-minute drive.

What other surf spots are near Nungas?
