Shipwrecks (Nusa Lembongan) Surf Forecast and Surf Report

Alright, folks, Rusty here. We’ve got a solid run of surf coming up for Shipwrecks on Nusa Lembongan. This is a reef break for advanced surfers only, and it’s consistent, so you can bank on waves. The water is sitting at 81° – pretty much what you’d expect for this time of year, no major surprises there.

The pattern is set: a persistent SSW groundswell, with periods hanging between 15 and 18 seconds for most of the run. That’s long-period energy, which means proper shaped waves with plenty of push, but at a reef break like this, it’s going to be a dream. The combined swell energy starts at 1084 (moderate) and builds into the strong range later on.

We kick off on Thursday morning, July 30th, with a 4 ft SSW swell and a 15-second period. The wind is a moderate offshore from the SE, keeping things clean. That’s a really nice start. The afternoon sees a slight cross-off wind, but it’s still clean. Friday the 31st is similar, with a 4 ft swell and a 17-second period, cross-off winds, and clean conditions. Saturday the 1st of August bumps up to 4 ft, then 5 ft in the afternoon with an 18-second period – that’s the standout for the first week. The combined energy hits 1346 (strong), and with a gentle breeze, it’s going to be glassy. Get on it.

Sunday the 2nd is a highlight: 6 ft SSW swell, 17-second period, and a gentle offshore wind from the ESE. That’s about as clean as it gets. The energy is up to 1774 (strong). This is prime time.

The next week holds more of the same quality. Monday the 3rd through Wednesday the 5th keep the 5 ft to 5 ft range, with offshore winds and clean conditions. The energy stays strong. Then Thursday the 6th and Friday the 7th see the swell jump to 7 ft – 7 ft with 16-17 second periods. The energy is huge, over 2000. This is getting into expert-only territory. The morning sessions are the go, with clean offshore winds. The afternoons are cross-off and a bit more average.

Saturday the 8th and Sunday the 9th settle back to 6 ft – 7 ft, still good. The real standout for the second week is Monday the 10th of August: 7 ft SSW swell, 15-second period, and a gentle offshore breeze. The energy is a massive 2220. That’s a morning session for the experienced crew.

Tuesday the 11th shows a shift in the afternoon with a 3 ft S swell and a 20-second period – that’s a very long period groundswell. At a reef, that’s going to be a thing of beauty. The energy is still strong.

We’ve got rain showers on a few mornings, but the wind stays offshore, so it won’t mess up the surface. The real big one to watch is Friday the 14th of August: 10 ft SSW swell, 17-second period. The combined energy is over 5200 – that’s very strong. The morning has cross-off wind, but the afternoon turns glassy. This is only for the hardest of the hardcore. It’s far out, so keep an eye on it, but it has the potential to be the best of the whole run.

Best of the lot: Sunday the 2nd of August morning for that perfect 6 ft offshore glass, and Monday the 10th of August morning for the bigger, clean 7 ft. Don’t sleep on the afternoon of the 14th if you’re an expert.

Rusty.
