Frequently Asked Questions

What kind of wave is Yo-Yo's?

Yo-Yo's is a reef break in West Sumbawa, Indonesia, that mostly breaks right.

What swell works best at Yo-Yo's?

Yo-Yo's 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 0.9m and handles up to about 2.4m, with the sweet spot around 1.6 to 2m. 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 Yo-Yo's?

A NE wind is dead offshore at Yo-Yo's, 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.

What tide is best at Yo-Yo's?

Yo-Yo's is at its best around the mid to high tide, roughly 0.7m to 1.8m on the local chart.

When is the best time of year to surf Yo-Yo's?

The most reliable run of swell at Yo-Yo's 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 Yo-Yo's?

The water at Yo-Yo's 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 Yo-Yo's good for beginners?

It's more of an intermediate wave, rated 6/10 for difficulty, so newer surfers are best off sticking to the smaller days. Expect a moderate crowd (4/10) when it's on. Things to watch for: sharp, shallow reef (booties help).

How do I get to Yo-Yo's?

The nearest airport on our list is SWQ, then it's roughly a 1.5-hour drive.

What other surf spots are near Yo-Yo's?

The closest breaks we track are Tropicals (0.8 km), Scar Reef (9.3 km) and Super Suck (18 km), handy when Yo-Yo's isn't working.
