Shipwrecks (Nusa Lembongan) Surf Forecast and Surf Report

Alright, Rusty here, let’s have a look at what’s coming up.

We’ve got a solid run of swell on the way for Shipwrecks (Nusa Lembongan). This is a reef break that’s best for advanced surfers, and it’s been consistent, so you can expect plenty of action. The water temperature is sitting at 80°F, which is about normal for this time of year, so no surprises there.

The standout period kicks off this Saturday afternoon, the 5th of September. We’ve got a clean 6ft SSW groundswell, with a long period of 16 seconds, and light cross-offshore winds from the SSE at 9 mph. The combined swell energy is strong at 1803, so there’s plenty of power in the water. This is a long-period swell, which can be a bit too straight for some beach breaks, but on a reef like Shipwrecks, it’s going to be offering some proper, well-shaped lines. This is the best on offer – get on it.

Sunday the 6th keeps the fun going. The morning sees another 6ft SSW swell, still very good, with the same light cross-offshore breeze. The afternoon eases a touch to 5ft, but the period holds at 16 seconds, keeping the quality high.

Monday the 7th is another good one. The morning has 6ft SSW swell, clean, with light winds. The afternoon drops a little in size to 6ft, and the wind picks up to 12 mph, which makes it a bit more marginal, but still very surfable.

Tuesday the 8th brings a shift. The morning has a smaller 4ft SSW swell, but the period jumps to 19 seconds, and the combined energy is very strong at 2397. The afternoon gets a bit bigger at 5ft, and the period is still excellent at 18 seconds. This is a prime window for experienced surfers, with excellent conditions. The wind is still light and cross-offshore.

Wednesday the 9th has the biggest swell of the run so far. The morning is 8ft, and the afternoon is 7ft, both from the SSW with a 16-second period. The combined energy is strong at 2588 and 2325. This is getting into the territory where it’s only for experts, and the cross-offshore wind from the S at 9 mph will keep it clean. This is the second standout – a proper big-wave day for the crew who know what they’re doing.

The rest of the first week, from Thursday the 10th through to Sunday the 13th, stays consistently good. Expect chest to head-high SW and SSW swells, mostly in the 5ft to 6ft range, with clean conditions and gentle to moderate cross-offshore winds. The combined energy stays in the moderate to strong range, between 1263 and 1928.

Moving into the second week, things get a bit more relaxed but still offer plenty of waves. Monday the 14th has a moderate offshore wind from the SE, which is a nice change, with 5ft to 6ft SSW swell. From Tuesday the 15th onwards, the swell drops off a little, with most days seeing 4ft to 6ft, but the conditions remain clean with light winds. The combined energy drops to around 700 to 1300, so it’s more moderate.

There’s a nice little pulse on Saturday the 19th and Sunday the 20th, with 5ft to 6ft SSW swell, very clean, and light winds. Sunday the 20th afternoon even goes fully offshore with a light breeze from the SE, making for some glassy conditions. This is a solid end to the run.

Overall, the first week is the clear winner, with the 5th and the 9th being the true standouts. The second week is more of a fun, mellow cruise, but still worth a paddle.

Rusty.
