Shipwrecks (Nusa Lembongan) Surf Forecast and Surf Report

Alright, this is Rusty. Let’s get into it.

We’ve got one spot on the radar for the next couple of weeks: Shipwrecks on Nusa Lembongan. It’s a consistent reef set-up that’s going to be working almost every day, so there’s no gap at the start – we’re straight into it. The water’s sitting at 81°, which is pretty much right where it should be for this time of year, no big surprises there.

The first real action kicks off Friday morning, September 4th. We’re looking at a clean 4ft SW groundswell, with a 14-second period pushing in. The wind is offshore from the SE, so the faces will be tidy. The combined energy is moderate at 524 – a solid start to get the arms turning. That afternoon the wind goes cross-offshore, and the forecast calls it marginal, so morning is the call.

Saturday morning, September 5th, the swell bumps up to 6ft from the SSW with a 16-second period, and the energy jumps to 1341. The wind is a gentle cross-off breeze, making for clean lines. This is a proper standout window. The morning session is the one to chase.

The standout stretch of this whole outlook runs from Sunday, September 6th, through to Wednesday, September 9th. Saturday’s size holds over Sunday morning with 6ft SSW swell and 14-second period, energy at 1591. Monday morning, September 7th, pushes 6ft at 14 seconds, still clean. But the real highlight is Tuesday, September 8th. The swell period stretches to 19 seconds, a very long groundswell, with 4ft SSW swell in the morning and 5ft in the afternoon. The energy skyrockets to 2532 and 2758 – that’s strong, powerful water moving through. Conditions are clean with a gentle cross-off breeze. This is a reef break, which is perfect for that kind of long-period energy – it won’t just close out. This is for experienced surfers only, though. Wednesday, September 9th, keeps the power going with 8ft and 7ft SSW swell, periods of 16 seconds, and energy over 2300. Again, that’s expert territory.

After that, the size drops a touch but stays solid. Thursday, September 10th, through Saturday, September 12th, we’re in the 5ft to 6ft range, with 15 to 16-second periods. The energy is still strong, between 1165 and 1794. The wind is mostly cross-off, keeping it clean. The crowds at Shipwrecks can be a thing sometimes, so be aware, but the quality on offer is worth it.

The second week gets a bit more interesting again. Sunday, September 13th, morning brings a 7ft SW swell with an 18-second period, and energy hits 3332 – that’s strong energy. This is another standout moment for experienced surfers. The afternoon is a bit windier but still good. Monday, September 14th, through Wednesday, September 16th, we’ve got consistent 5ft to 6ft SW swell, periods between 14 and 16 seconds, and offshore winds in the mornings. The energy stays in the 1000 to 1492 range, so it’s moderate to strong. Thursday, September 17th, and Friday, September 18th, keep the pattern going, with a fun 6ft on Thursday morning and a gentle offshore on Friday morning for 4ft. Friday afternoon sees a 3ft swell with a 20-second period – very long period, but small. The energy is still moderate at 1194, so the sets will be spread out but have shape.

To wrap it up, Saturday, September 19th, brings 6ft SSW swell with a 16-second period, and a light breeze from the SSE making for clean conditions. A good way to finish the run.

Best on offer: Tuesday, September 8th, for the long-period groundswell and clean conditions, and Sunday, September 13th morning, for the biggest energy spike. Both are expert-only with the size and power.

Rusty, signing off.
