Shipwrecks (Nusa Lembongan) Surf Forecast and Surf Report

Alright, grab your board, let’s talk about what’s been cooking right here on our local reefs. The next couple of weeks have some real juice, but we gotta pick our sessions smart.

We’re looking at Shipwrecks (Nusa Lembongan) as the main show. This is a sheltered reef, only for the experienced crew, and it’s a consistent spot. The water temp is sitting right about average for this time of year, so nothing weird there.

The pattern starts off with a nice, long run of surf. Tuesday the 25th kicks things off with a solid 4.6 ft SSW groundswell, with a period of 15 to 16 seconds. That’s proper long-period energy, and the wind is a clean offshore from the SE, keeping it tidy. The combined energy is moderate (897 to 933). It’s not huge, but it’s a good start.

Wednesday the 26th holds similar size in the morning with a clean offshore wind, but the afternoon gets a bit cross-off, making it trickier. The swell period drops to 14 seconds, still decent.

Thursday the 27th sees the swell dip to 3 ft, but the period jumps back to 16 seconds early, and the offshore wind is light. The energy is moderate (981). That morning session is worth a look for a more relaxed paddle.

Now, Friday the 28th is a standout. The swell jumps to 7.9 ft in the morning, coming from the SSW with a 16-second period. The combined energy hits 2928, which is strong. This is a dedicated groundswell. The wind is a gentle cross-off breeze, keeping it clean. This is expert territory – over 8 ft gets gnarly, but 7.9 ft is that sweet spot for a heavy reef. This is the best on offer for the first week.

The weekend rolls in with Saturday the 29th dropping to 5.6 ft, still a clean cross-off wind, and good energy (1203). Good, solid surfing. Sunday the 30th brings back a clean SE offshore, with 4.3 ft swell and moderate energy (746 to 784). A nice, clean day.

Monday the 31st is interesting. The swell is 4.3 ft in the morning, but the period stretches to 19 seconds – very long. The energy is up to 1358. Be aware, that long period can make a reef break like Shipwrecks a bit more challenging, with longer lulls between sets, but the shape can be phenomenal with that light cross-off wind.

Looking into the second week, things stay solid. Tuesday 1st September to Thursday 3rd September we have a consistent run of 4.6 ft to 5.9 ft SW swell, with offshore winds holding for the mornings. The energy stays moderate to strong (up to 1741). The mornings are the call.

There’s a bit of a lull from Friday 4th September through Saturday 5th September, where the swell drops below 3.3 ft and the ratings drop off. The combined energy is weak (as low as 373). Not much doing for a couple of days.

But then Sunday 6th September fires back up with a 5.6 ft SSW swell and a 15-second period, with clean cross-off winds. Good energy (1259).

Monday 7th September is similar, with a light offshore wind in the morning making for a glassy session at 5.2 ft. Lovely.

And then we get the final punch. Tuesday 8th September and Wednesday 9th September are the real late standouts. The swell is 5.6 ft to 7.2 ft, with a period that hits 20 seconds on Tuesday morning. The combined energy is massive – 3343 to 3847. That is very strong, very long-period groundswell. The wind is light and cross-off. This is, again, for experts only, but it’s a world-class window. It’s over a week away, so keep an eye on it, but this is the other standout.

So, to sum it up: Friday 28th August and Tuesday 8th / Wednesday 9th September are your prize sessions. Big, powerful, long-period groundswell on a reef. Bring your A-game. Crowds are listed as 'sometimes' at Shipwrecks, so on days like this, expect company.

Stay stoked.
