Shipwrecks (Nusa Lembongan) Surf Forecast and Surf Report

G’day, Rusty here.

We’ve got a solid run ahead at Shipwrecks on Nusa Lembongan. This is a consistent, advanced reef break, and right now it’s cranking with long-period south-west groundswell. Water temp is sitting at 81°F, which is pretty much normal for this time of year.

The week kicks off on Wednesday the 2nd of September with clean offshore south-easterly winds around 16 mph, pushing into a 5ft SW groundswell at 16 seconds. Massive energy in the water (1436 combined energy). Not for beginners at that size, but if you know what you’re doing, it’s gonna be unreal. That stays strong through Wednesday afternoon. Thursday drops a little to 4ft with the same clean offshore flow and still plenty of punch. Friday’s still nice but the swell backs off a touch to 4ft; morning stays clean with offshore wind, but the wind goes cross-off in the arvo which can gum things up a little.

Saturday the 5th sees a new pulse jump back up to 6ft from the SSW, with periods at 16 seconds again. Wind is cross-off but light on Saturday arvo with a gentle breeze, making for clean conditions and huge combined energy (1474). Sunday bumps up a bit more to 6ft, morning is a little mixed with some clouds and cross-off breeze, but the arvo turns clean again with lighter wind. Monday the 7th keeps pushing with a 7ft SSW swell, cross-off and clean – honestly a standout stretch, with plenty of grunt (1810 combined energy).

Then we get to Tuesday the 8th, which is the first proper standout. The swell drops slightly to 5ft but the period jumps to 19 seconds – that’s very long period groundswell, meaning plenty of power and long lines, perfect for this reef setup. Combined energy is 2408 but it jumps to 2961 in the arvo, even though there’s a caveat at the reef with such a long period. Wind is a gentle cross-off, so conditions will be glassy and clean. This is the one to circle. Wednesday the 9th keeps the quality high with a 7ft SSW swell at 16 seconds, clean offshore flow, and excellent energy (2310). Thursday and Friday ease a little but still hold fun shoulder-high sets.

The next real standout is Saturday the 12th of September. Swell sits at 5ft from the SW with a 16 second period, combined energy climbing to 2155 in the arvo. Conditions are clean and the reef will be offering up some serious shape. Sunday the 13th pushes bigger again – 8ft early with offshore SE winds, 18 second period, combined energy blasting up to 3630. That’s serious power and only for experienced surfers. The arvo gets a bit messier with cross-off winds, but the morning session will be firing.

Monday the 14th holds a solid 7ft, moderate offshore breeze, clean. Tuesday settles down a little. Wednesday the 16th and Thursday the 17th both look excellent, with 7ft to 8ft SSW swells, 16 second periods, clean conditions, and combined energy over 2000. Thursday arvo pushes over 3000 again. This is a long, consistent run of quality surf, with the absolute best being Tuesday the 8th and Sunday the 13th. Both are clean, powerful, and for advanced crew only. Crowds are possible, as noted, so pick your session wisely.

Rusty.
