Lacerations (Nusa Lembongan) Surf Forecast and Surf Report

G’day, Rusty here. We’ve got a solid run ahead at one spot, and it’s a proper big-wave reef setup for the experienced crew only. This is a long-range outlook, so while the first week is locked in, the second week has some promising signals that are a little less certain.

Right from Monday, 10 August, Lacerations (Nusa Lembongan) is pumping. We’re talking a 6 ft SSW groundswell with a very long 19-second period – that’s serious energy (combined swell energy of 2999). The wind is a light offshore from the SE, so expect clean, lined-up waves. Water temp is 81°, which is about normal for this time of year. This is advanced-only territory, and the reef doesn’t mess around. The swell direction (SSW) matches perfectly with what this break likes (SW). Crowds are often, so you’ll have company, but the consistency is inconsistent, so pick your moments.

The pattern holds through Tuesday and Wednesday. Tuesday morning, 11 August, sees the swell bump up to 10 ft from the SSW with a 17-second period, still under a cross-offshore breeze. Combined energy is 4140 – strong stuff. Wednesday morning, 12 August, it’s 7 ft from the SSW, offshore wind, energy at 2321. Excellent conditions for those who can handle it.

Thursday, 13 August, the swell holds at 8 ft but the wind swings cross-offshore, making it a bit trickier. The energy is still high at 3347. Friday and Saturday, 14 and 15 August, we’re back in the 7 ft range with gentle cross-offshore breezes – clean but demanding.

Sunday, 16 August, has a slight drop to 6 ft with a light offshore in the morning. Still solid. Then Monday, 17 August, the swell drops to 5 ft, energy down to 887 – good but less powerful.

Now for the second week. Tuesday, 18 August, morning has a small 3 ft SSW groundswell with a 16-second period and light offshore wind – clean but small. Then the afternoon brings a 3 ft swell with a very long 20-second period and offshore wind, energy at 1767. That’s a sneaky good session for the patient surfer.

Wednesday, 19 August, the swell jumps back up to 7 ft from the SSW with a moderate offshore breeze and energy at 3187. Thursday, 20 August, holds at 7 ft, this time from the SW with offshore wind, energy at 2528. Both mornings are excellent for experienced surfers.

Friday, 21 August, through to the end of the outlook sees the swell staying in the 6 ft to 8 ft range, with mostly cross-offshore winds. Saturday, 22 August, has rain showers but a morning offshore breeze with 6 ft swell. Sunday, 23 August, kicks back up to 8 ft in the morning with a moderate offshore, energy at 2820, and the afternoon hits 8 ft with cross-offshore wind and energy at 4931 – that’s the strongest energy of the whole period. Monday, 24 August, holds at 7 ft with offshore wind. Tuesday, 25 August, drops to 5 ft, still with a moderate offshore breeze.

Best on offer? The standout is Wednesday morning, 19 August, and Sunday morning, 23 August. Both have excellent conditions for experienced surfers, with solid 7 ft to 8 ft SSW swell, moderate offshore wind, and combined energy well over 2800. These are the sessions to circle.

Remember, this is an inconsistent, advanced reef break. If you’re not comfortable with big, fast waves over a shallow reef, give it a wide berth. For those who are, it’s going to be a memorable run.

Rusty.
