Pantai Morosi is a quality left reef break around the headland from the famous Nihiwatu (Occy's Left) on West Sumba. The wave offers similar S-SW swell exposure but without the exclusive resort access restrictions, making it accessible to free-roaming surfers exploring Sumba's wild south coast. The wave works across a range of conditions and provides a good alternative when NIHI Sumba's break is off-limits.

Pantai Morosi is a reef break in West Sumba, Indonesia, that mostly breaks left.
Pantai Morosi 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.
An E wind is dead offshore at Pantai Morosi, 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.
Pantai Morosi is at its best around the mid to high tide, roughly 0.7m to 1.8m on the local chart.
The most reliable run of swell at Pantai Morosi 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.
The water at Pantai Morosi 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.
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).
The nearest airport on our list is TMC, then it's roughly a one-hour drive.
The closest breaks we track are Pero Lefts (3.3 km) and Occy's Left (11 km), handy when Pantai Morosi isn't working.
