Frequently Asked Questions

What kind of wave is Occy's Left?

Occy's Left is a reef break in West Sumba, Indonesia, that mostly breaks left.

What swell works best at Occy's Left?

Occy's Left 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 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 Occy's Left?

An E wind is dead offshore at Occy's Left, and anything from the NE round to the SE 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 Occy's Left?

Occy's Left 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 Occy's Left?

The most reliable run of swell at Occy's Left 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 Occy's Left?

The water at Occy's Left 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 Occy's Left good for beginners?

Not really. It's rated 7/10 for difficulty and suits experienced surfers. The lineup is usually quiet (crowd 2/10). Things to watch for: sharp, shallow reef (booties help) and long hold-downs.

How do I get to Occy's Left?

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

What other surf spots are near Occy's Left?

The closest breaks we track are Pantai Morosi (11 km) and Pero Lefts (15 km), handy when Occy's Left isn't working.
