Shipwrecks (Nusa Lembongan) Surf Forecast and Surf Report

Alright, Rusty here. Let’s talk about what’s cooking.

Straight up, this is an absolute run of quality for Shipwrecks on Nusa Lembongan. We’ve got a solid, consistent south-west groundswell filling in over the next 16 days, and that offshore wind is locked in more often than not. The water is sitting right on 81°, which is just about normal for this time of year, so no surprises there.

The pattern starts Sunday morning, July 26th, with a solid 8ft swell out of the south-east at 9 seconds. The combined wave energy is already pumping at 1780 (strong to very strong), and with a clean ESE offshore breeze, this is a proper standout. The waves will be powerful, well-shaped, and pushing through on the reef. Expect some crowd action here – it’s a known spot and people will be on it.

By the afternoon, the wind picks up to 19 mph from the SE, and while it’s still offshore, the conditions get a bit rougher. The swell drops slightly to 7ft, and the energy dips to 884. It’s still surfable, but the morning is the clear winner for Sunday.

Monday and Tuesday (July 27-28) keep the swell in the 6ft to 7ft range, but the wind stays fresh offshore. The period drops to just 7-8 seconds, so the waves will be a bit steeper and more crumbly. The energy stays in the moderate range (638-703). Not bad, but not as smooth as the opening day.

Wednesday morning, July 29th, we see a shift. The swell drops to 4ft but the period jumps to 14 seconds – proper groundswell. The direction swings to SSW, which is the optimum for this reef. The energy climbs to 756. Even though it's smaller, the longer period means more push and shape. This is a good day for a longboard or a funboard.

Now, Thursday through Saturday (July 30 - August 1) is where it gets special. The swell holds around 3ft to 5ft, but the period extends into the 15-18 second range. The energy readings are in the four-digit zone – 1127, 1060, 1358 – that’s strong, high-quality swell. The wind is clean offshore or gentle cross-off. The waves will be glassy, lined up, and offering some proper long rides on the reef. Saturday afternoon, August 1st, with a 5ft, 18-second SSW swell and a gentle offshore, is a serious highlight.

The first week of August keeps delivering. Sunday, August 2nd, has a 6ft to 6ft SSW swell with 16-17 second periods, and the combined energy hits 1514 to 1938. This is big, powerful, and clean. A bit much for beginners, but for anyone comfortable in overhead surf, it’s going to be epic.

Monday, August 3rd, backs off a bit to 5ft and 15 seconds, with a gentle offshore. Still very, very good. Tuesday, August 4th, the swell drops to 5-5ft, and the wind goes cross-offshore. It’s clean but the energy dips to 824-877.

Then Wednesday, August 5th, the swell is only 4-4ft, but check this out – the period goes to 14-19 seconds. The energy jumps to 1266 and 1422. On the reef at Shipwrecks, that long period groundswell will wrap in perfectly, giving you clean, long walls. It may be smaller, but the quality is high.

The true standout of the whole run is Thursday, August 6th. We’ve got a 7ft SSW swell with a 16-second period, combined energy of 2046 (very strong), and a light 9 mph E offshore breeze. The file says it’s excellent for experienced surfers – and I agree. That’s the day to clear your calendar. The following Saturday, August 8th, runs it close with a 6-7ft SSW swell, 16 seconds, and a gentle cross-off. The energy is massive at 2066 and 2257.

The run winds down from August 9th to 10th. The swell drops back to 4-6ft, still with good period and clean conditions, but the energy is more moderate (1080-1745). Still very surfable, but the real fire is in that first two weeks.

Overall, there is no gap here. This is a 16-day stretch of consistent, quality reef surf. The best days are Sunday July 26th morning, and Thursday August 6th – that’s your pick of the litter. Get on it.

Rusty.
