The Lowdown
Alright folks, Rusty here. Let’s have a look at what’s shaping up for us around Shipwrecks (Nusa Lembongan).
We’re kicking off a solid run of surf. It’s not a fluke, this area has been consistent, and this forecast shows a lot of wave energy across the 16-day window. The water is sitting at 81°, which is pretty average for this time of year, so no shocks there.
First thing Monday morning, we’ve got a clean 6.6ft swell from the southeast. The period is a short 8 seconds, so it’s a bit fat and bouncy, but the wind is offshore from the ESE at 16 mph, keeping the surface clean. The energy is moderate at 728, but it’s a working wave for experienced surfers. That morning is your best bet for the start because the afternoon gets a bit too windy, with a fresh 22 mph from the SE making the quality drop off.
Tuesday is a bit of a mixed bag. The morning swell drops to 5.6ft with a short 7-second period, and the wind is still fresh offshore from the SE at 19 mph. It’s a bit choppy. Then Tuesday afternoon, something interesting happens: the swell direction swings to the SSW and the period jumps to 16 seconds – we’re talking real groundswell now. The wave height is just 2.6ft, but the combined energy is moderate at 589. The wind is moderate offshore, so it’s clean, but it’s small. You’d need a longer board.
Wednesday and Thursday see a solid SSW groundswell building. Wednesday morning has 3.6ft at 14 seconds, and the energy bumps to 750. The wind is moderate offshore from the SE, so it’s clean. By Thursday morning, we hit 4.3ft at 15 seconds, with the energy jumping to 1041 – that’s a meaty, powerful wave. The wind is moderate offshore again at 12 mph. That Thursday morning is the first real standout: clean, good period, and pumping energy. Thursday afternoon the wind goes cross-off, so it gets a little less perfect but still order.
Friday through to the weekend is where it starts to get spicy. Friday morning is clean with 3.3ft at 17 seconds, and the energy is 1199 – that's a lot of grunt for the size. The wind is a light cross-off, but it’s still rideable. Friday afternoon the wind drops to a gentle breeze from the SE at 9 mph, and it’s a cross-off, but the waves are 3.6ft at 17 seconds and the energy is 1070. It’s very good, but the slight cross-off wind might just knock the top off a bit.
Then we hit Saturday and the weekend, and this is the real highlight. Saturday morning opens with 4.3ft at 16 seconds, a light ESE offshore breeze at 6 mph, and energy at 1026. That is about as clean as it gets. Saturday afternoon builds to 4.9ft at an 18-second period, and the combined energy is 1352. Light wind, clean, long period – that’s a dream combo for a reef break.
But the absolute best on offer, the true king of this run, is Sunday, the 2nd of August. Both the morning and afternoon sessions are absolute magic. The swell hits 6.6ft from the SSW with a 17-second period, and the energy rockets to over 2100. The wind is gentle and offshore in the morning and moderate offshore in the afternoon. This is excellent, powerful, clean groundswell for experienced surfers. This is not a day for beginners; 6.6ft is getting up there and the period is long, so the sets will have serious push and will be focusing on the reef.
Monday the 3rd remains very good, with 5.6ft at 15 seconds and moderate offshore wind. The energy is still strong at around 1300. Tuesday the 4th is similar – 5.6ft at 14 seconds, gentle offshore breeze, very clean.
Now, from Wednesday the 5th through to Friday the 11th, we get a lot of solid surf, but the winds are mostly cross-off, so the quality is a bit glossier, not quite as glassy. We do get a second real standout on Thursday the 6th of August. Both morning and afternoon see 6.6ft at 17 seconds, moderate offshore winds from the SE, and the combined energy soars to 2450. That is a heavy, powerful swell with excellent conditions for experienced surfers. It’s a proper big-wave day at Shipwrecks. Friday the 7th is nearly as big, with 6.2-6.6ft at 16 seconds, but the afternoon goes cross-off again, so the morning is the call.
The final few days, from the 8th to the 11th, show a slow drop-off in period and size, but we still see 5.2ft to 6.6ft swells with moderate energy in the 1200-2000 range. The winds are a mix of cross-off and offshore, so there are still good windows. The 10th and 11th have some good morning offshore windows with strong energy.
