Lacerations (Nusa Lembongan) Surf Forecast and Surf Report

Alright folks, Rusty here. Let's have a look at what's on the cards for the next couple of weeks.

The standout spot for this entire forecast period is Lacerations (Nusa Lembongan), and for good reason. We’ve got a solid run of consistent SSW groundswell with some seriously long periods, and the water’s sitting at a comfortable 80°F, which is pretty much bang on average for this time of year. This is a reef break that only works on a SW swell direction, and that’s exactly what we’ve got coming in, so it’s dialled in.

We kick off Sunday, August 23rd, with a clean 6 ft SSW swell, a 15-second period, and a moderate offshore breeze from the SE. The combined energy is strong at 1653, and it’s a really good start. That offshore wind will have it looking smooth. The morning is the pick, as the afternoon goes cross-off. The swell stays solid through Monday, August 24th, with 6 ft and a 16-second period, but the wind is cross-off, so it’s not as clean as Sunday morning.

Tuesday, August 25th, is a real highlight. The morning sees a 5 ft SSW swell with a 15-second period, and it’s offshore again. That’s a sweet combo. The afternoon picks up to 5 ft with a 16-second period, still offshore, with the energy jumping to 1258. That’s a quality session.

The big one lands on Friday, August 28th. We’re looking at a 8 ft SSW swell, 16-second period, and light cross-off winds. The combined energy is a massive 2964 – that’s some serious power. This is excellent surf, but at that size, it’s for experienced surfers only. It’s a little too big for beginners.

We then get a bit of a lull, with smaller, cleaner waves around the 3 ft to 5 ft mark through the end of August and into early September. The wind is generally light and offshore or cross-off, so there’s still fun waves to be had, especially on the mornings. Monday, August 31st, has a 3 ft, 19-second period groundswell. That’s an incredibly long period, which will mean long, clean lines, but it might be a bit straight for a beach break – though this is a reef, so it should handle it nicely.

Looking further out, the energy picks up again on Saturday, September 5th. We’re looking at 7 ft to 7 ft SSW swell, 17-second period, with combined energy around 2300. The wind is cross-off, but the forecast is a bit less certain that far out. It’s something to keep an eye on, but I wouldn’t book your flights just yet. A similar pattern rolls through the 6th and 7th of September, with solid 6 ft to 6 ft SSW swell and decent conditions.

The Bottom Line: The standout window is definitely the 7-day stretch starting Sunday, August 23rd, through to the end of the month. The best single day is looking like Friday, August 28th for the big-wave crew, but for the best all-round conditions with good size and offshore wind, Tuesday, August 25th is a cracker. The crowds are a factor here, it’s often busy, so you’ll want to be on it early.

Rusty.
