Shipwrecks (Nusa Lembongan) Surf Forecast and Surf Report

Alright, let’s get into it. This is Rusty, and I’ve been staring at the charts for our little corner of the world here at Shipwrecks (Nusa Lembongan). Listen, if you’re after a classic, consistent run of surf, you’ve come to the right place. The next couple of weeks are looking stacked with a solid, steady pulse of SSW groundswell, and the wind is playing ball most of the time. The water is sitting at a warm 82°, which is about 2° warmer than usual for this time of year – just that little bit of extra tropical warmth you can feel on your skin.

We kick things off on Wednesday the 29th of July. It’s not huge, with waves around 4 ft to 4 ft, but that 14-second period from the SSW has some real push to it. The wind is a steady offshore from the SE at 15 mph, so the faces are going to be clean and lined up. The combined energy is sitting at 777, which is moderate but feels punchy for the size. A solid starter.

Thursday the 30th is where it starts to really hum. The swell bumps up to 4 ft in the morning, the period stretches to 15 seconds, and the energy jumps to 1053 – now we’re talking. That morning session is looking very good with that same clean offshore wind. The afternoon gets a bit tricky with a cross-off wind, so get out early.

Friday the 31st through Saturday the 1st of August, the swell eases a fraction but stays in that sweet 3 ft to 5 ft range. The period gets long, up to 17 seconds, so expect proper groundswell lines with nice long lulls between sets. Winds are lighter, 6 to 9 mph, keeping it glassy or clean. This is the kind of cruising surf where you can pick them off without too much drama.

Now, Sunday the 2nd of August is a standout. The swell pushes up to 6 ft with a 17-second period, and the energy hits 1774. More importantly, that ESE wind is offshore and light at 9 mph. The whole morning slot is clean, offshore, and pumping. This is the pick of the first week.

Monday the 3rd backs off a touch to 5 ft to 5 ft, but it’s still very clean. The morning has a light breeze, making for some beautiful, smooth surf.

As we move into the second week, the swell starts to build again, and this stretch is for the experienced crew only. By Thursday the 6th of August, we’re looking at solid 6 ft surf with a 17-second period. The energy is well into the strong range at 2132. The morning offshore wind is there, making for some excellent, powerful surf, but this isn’t a beginner’s wave anymore.

Friday the 7th and Saturday the 8th of August see the swell hit 7 ft to 7 ft. This is expert territory. The wind holds offshore in the mornings, but it’s a fresh breeze at 19 mph, so you need to be on your game. The energy numbers are massive – over 2300 – so there’s a lot of water moving around. Afternoons turn cross-off, so stick to the early sessions.

The biggest pulse of the whole run looks set for the 9th and 10th of August. Waves are 8 ft to 8 ft with that same long SSW energy, and the power is through the roof. Sunday morning the 9th looks excellent with offshore wind, but by the 10th the wind goes cross-off and the conditions get trickier. This is big, serious surf.

Then, around the 11th and 12th of August, the forecast shows a spike into 10 ft to 13 ft on the 12th, with period hitting 19 to 20 seconds and energy readings in the thousands. That’s massive, very long-period groundswell. For a reef like Shipwrecks, that’s going to be a heavy, deep-water event. Only for the most experienced chargers, and conditions could get a bit unruly in the afternoon cross-off winds. The morning of the 13th of August offers a bit of a reprieve, dropping back to 8 ft with offshore wind – still big, but more manageable.

The standout for the entire period? I’d have to say Sunday the 2nd of August. That’s the perfect balance of size (6 ft), period (17 seconds), clean offshore wind, and manageable conditions. After that, the mornings of the 6th, 7th, and 8th of August are for the experts looking for a serious challenge.

Keep the 12th of August circled on your calendar – that massive 13 ft forecast is a long way out, so it’s promising but we’ll have to see how it firms up. For now, the next two weeks have got the goods.

Rusty.
