Table - best surf conditions forecast for Lacerations (Nusa Lembongan) over the next 16 days.
Alright, Rusty’s back with the imperial version. Same spot: Lacerations (Nusa Lembongan) – a reef for advanced hands only, inconsistent, often crowded. Water temp is about 82°F, right around average for the season.
We start Sunday July 12 with small, clean surf – 2ft from the SW, 13 seconds, light offshore ESE breeze. Monday morning stays tiny (2ft) but Monday afternoon brings a sweet 3ft SSW swell with a 21-second period – a very long groundswell that’ll wrap into the reef nicely. The sets are spaced, but the shape will be steep. Offshore wind holds.
The first standout is Tuesday July 14: morning 5ft SSW at 17 seconds, gentle offshore, afternoon builds to 6ft at 18 seconds. Combined energy is strong (2115 and 2250). That’s the session to aim for early on. Wednesday and Thursday are still good – 4–6ft, moderate offshore winds.
Friday July 17 goes smaller – 4ft, fresh offshore but marginal. Saturday and Sunday are clean but only around 4–4ft. Then Monday July 20: 7ft SSW at 17 seconds, energy 2888, morning offshore. That’s a big one – experts only. Tuesday still 6ft, then it fades.
The real fireworks come Saturday July 25: 7ft SSW, afternoon 8ft SSW, both with offshore winds, energy over 3100. Sunday July 26 holds 8ft, also offshore. That’s the biggest, best window of the whole 16 days. Powerful, long-period groundswell, reef working perfectly. But at 8ft, it’s only for the brave.
Best bets: Tuesday July 14 and the weekend of July 25–26. Don’t expect constant waves – it’s inconsistent here – but when it lines up, it’s special. Stay sharp, Rusty out.
