Shipwrecks (Nusa Lembongan) Surf Forecast and Surf Report

G’day, Rusty here. We’ve got a ripper run of swell on the cards at Shipwrecks on Nusa Lembongan, and it’s looking like one of those stretches where you just want to clear the calendar. The water is sitting at about 80°F, which is pretty much what you’d expect for this time of year – no surprises there.

We kick off this Sunday morning, 13 September, with a clean 4ft SW groundswell pushing through at a long 18 seconds. That’s proper energy from deep water, and it’s firing straight into a sheltered reef setup. Winds are light and offshore from the SE, so the faces will be glassy. The combined swell energy is strong at 1504, and it’s only building through the day to 6ft by the afternoon. This is advanced-only territory given the reef and the punch, but for those who know the lineup, it’s a standout morning.

Monday the 14th holds steady – 5ft SW swell with a 16-second period, moderate offshore breeze, and energy readings around 1085. Still clean, still solid. Tuesday morning the 15th sees 5ft SW swell at 15 seconds, still offshore, and the energy is moderate to strong at 1019. The afternoon shifts to a cross-off breeze though, and the forecast flags a trickier tide – still decent but not the peak.

Wednesday the 16th has a morning window of offshore 5ft SW swell (928 energy), but the afternoon gets a bit messy with a cross-off and a shift in direction. Thursday the 17th bounces back with a 5ft SSW swell for the morning, gentle offshore breeze, and energy climbing back to 1110. Friday the 18th and Saturday the 19th ease off a touch – 4ft to 5ft SSW swells, lighter winds, but still clean and surfable.

Now, keep your eyes on Sunday the 20th. That morning delivers 5ft SW swell with a 16-second period, light offshore breeze, and energy spiking to 1380. It’s a proper standout again. The run then settles through Monday and Tuesday, but come Wednesday the 23rd we get a pulse – 6ft SSW swell, clean conditions, energy at 1386. Thursday the 24th is the real bomb: 7ft SSW swell at 17 seconds, combined energy hits 2174 – that’s strong to very strong. The forecast calls it excellent for experienced surfers, and with light winds, it’s going to be a session to remember. This one’s the top pick of the whole outlook.

The run stays solid right through to Monday the 28th, with 5ft to 6ft SSW swells, clean conditions, and energy staying well above 1200 most days. The consistency is excellent, and the winds are almost always offshore or cross-off, so you’ll get your share of clean waves. Crowds at Shipwrecks can be an issue – it’s a well-known spot – but with this much swell on offer, there’ll be waves for everyone in the water who knows what they’re doing.

Rusty.
