Shipwrecks (Nusa Lembongan) Surf Forecast and Surf Report

Alright, Rusty here, let's have a good look at what's coming our way.

Alright, listen up. The next couple of weeks are looking like a solid, sustained run for the experienced crew only. We’ve got a constant feed of strong, long-period groundswell from the SSW lining up perfectly for Shipwrecks (Nusa Lembongan). This isn't a week of small, choppy slop; this is a proper event. The water temp is sitting at a very pleasant 81°F, which is bang on average for this time of year, so no surprises there. The combined swell energy is through the roof, with readings regularly hitting four-digit figures (like 4429 to 5697), meaning there's a serious amount of power in the water.

It kicks off from the get-go on Tuesday, August 11th. Morning sees a solid 10ft swell with a very long 17-second period. The wind is a clean 9 mph cross-off from the SE, meaning clean, well-shaped lines. This is big, powerful reef break surfing and not for the faint of heart. The afternoon holds similar size but the wind gets up a touch, though it stays clean.

Wednesday the 12th drops to 7ft in the morning with consistent offshore wind from the SE, making for some beautiful, clean walls. That trend holds through Thursday the 13th with another 8ft morning on offer, again with offshore wind.

The standout period really looks to be the middle of the second week. On Wednesday the 19th and Thursday the 20th of August, we’ve got offshore winds all day long, with solid 7ft SSW swell (17-second period) and excellent surf conditions. The energy readings are very high (2473 and 2283), and that combo of strong, clean swell and perfect wind direction is as good as it gets here.

Even the days that are a bit smaller, like the 5ft to 6ft range around the 17th and 18th, still have that long-period groundswell and offshore wind, so the quality will be high, just with a bit less grunt. Just be aware, this spot can get crowded sometimes, and with a run of surf like this, you'll want to be early.

There's a bit of a drop-off towards the end of the month, with the swell easing on the 23rd and 24th, but even then, it's still rideable on a bigger board. The promise of another pulse of solid swell on the 25th (6ft, 18-second period) means the pattern isn't finished yet. Overall, if you’ve got the skills for a heavy reef break, you’re going to be very, very happy over the next fortnight.
