The Lowdown
G’day, I’m Rusty. Let’s talk about what’s heading for Nipussi (Nyang-Nyang) over the next couple of weeks. It’s a consistent, exposed reef break that likes a west swell direction, and this outlook shows a real mixed bag. Water temps are sitting right around 85°, which is pretty much average for this time of year, so nothing out of the ordinary there.
The first recommendation coming through is actually not much – Saturday the 15th morning shows some lumpy onshore SSE breeze at 12 mph with 5 ft S swell, but the wave energy is moderate-to-strong (1612) and the conditions are poor. That afternoon and Sunday are just marginal. Not the sort of stuff to get excited about. We’ve got a long stretch of drifty, onshore wind that’ll keep things messy through the early part of next week.
The first real standout sits on Tuesday the 18th morning. It’s still onshore from the SSE at 12 mph, but the swell is building to 8 ft SSW with a period of 16 seconds – that’s proper groundswell energy right there (2807). The size and the long period mean decent shape, but it’ll be a workout for advanced surfers only, and that onshore breeze will put a bit of texture on it. Crowds are possible here.
Now for the big one – Wednesday the 19th morning and afternoon. Swell hits 10 ft SSW with a 17-18 second period, and the combined energy jumps right up (4838 to 5405). That’s strong, powerful, proper reef stuff. It’s expert territory for sure – too big for anyone but the experienced crew. Winds are onshore but light, so it won’t be total chaos, but set your expectations. This is the best on offer across the entire outlook. The whole week after that stays solid, with 7 ft to 10 ft SSW groundswell, but the wind never truly cleans up, staying onshore or cross-on from the southeast or south. Not ideal, but for the size, it’s still surfable.
As we push further out, the swells drop off a notch around 24th and 25th August – down to 4 ft to 5 ft – and the energy dips below 1000 on some afternoons, meaning weaker, less exciting waves. There’s a little pickup toward the end of the month: Thursday the 27th and Friday the 28th see 7 ft to 7 ft SW swell with 16-17 second periods, but the wind stays onshore or light cross-on, so expect lumpy but rideable conditions. Then the final Sunday the 30th really comes in with another 10 ft SSW pulse and extreme energy (4972 to 4810) – but same story with onshore wind and the risk of thunderstorms. For the experienced surfer, that’s a big slab to handle.
Overall, Nipussi isn’t going to deliver pristine, glassy waves in this window, but if you’re keen for size and power, middle week and the final weekend are your targets. Keep an eye on the wind – it’s the only thing holding it back.
Rusty.
