The Lowdown
G’day, Rusty here. Let’s talk about Shipwrecks (Nusa Lembongan) for the next couple of weeks – and there’s some proper gold in here.
First up, the water’s sitting at about 80°, dead average for this time of year – no drama there. Swell energy starts moderate Monday the 17th morning at 744, but by Tuesday the 18th it jumps to 1528 – that’s strong energy brewing. Wednesday the 19th is the real standout: morning sees 7ft from the SSW with an 18-second period, light offshore breeze at 6 mph – glassy, clean, and pumping. Afternoon holds 7ft same direction, still offshore. This is groundswell with real bite, and on a reef break like this, the long period will wrap in perfectly. But over 8ft means experts only.
Thursday the 20th morning brings 8ft from the SW, 16-second period, gentle offshore – energy still very strong at 2793. If Wednesday’s too wild, this is your next best bet.
Friday the 21st afternoon has 7ft from the SSW with moderate offshore wind, and Saturday the 22nd morning holds 6ft from SSW, still offshore. Then it drops a bit – Sunday the 23rd morning has 6ft, still clean.
Second week: from Monday the 24th through September 1st, the swell sits between 2ft and 6ft, periods mostly 13 to 18 seconds. Winds stay favourable – often offshore or cross-off. Highlights include Thursday the 27th morning: 2ft but with an 18-second period and light offshore – a beautiful little clean wave for logs or fun mid-lengths. Then Sunday the 30th and Monday the 31st see the swell climb back to 5ft with 16-second period – a nice way to close out the window.
Crowds are “sometimes” at Shipwrecks, so on the big days you’ll have some company. The break is consistent, so there’s always something to ride. If you’re not advanced, steer clear of the 6ft+ days – that reef and power is serious.
No gaps here – surf runs almost every day from the 17th right through. If I had to pick one, it’s Wednesday the 19th morning. That’s the one to circle.
Rusty.
