The Lowdown

Alright folks, Rusty here. Let's break down what's coming our way. We've got a solid window of waves on the radar, but it's not going to be all clean and perfect. The standout period is definitely around Wednesday the 19th, and then again towards the end of the month.

The run starts on Tuesday the 18th with a bit of a tease. We've got a 8ft SSW swell out of the southwest at 16 seconds, but it's a bit of a mess. The wind is on it from the SSE, and the call is marginal. It's not really worth getting wet for anything special. The energy is moderate at 2908, but quality is missing.

Wednesday the 19th is where it starts to get interesting. That's the first real push of the run. Swell jumps up to 10ft, still from the SSW, with a period of 17-18 seconds. That's some proper groundswell energy, and the combined energy is strong, hitting 5310 in the morning and 5718 in the afternoon. It's a big, powerful swell, so this is for the experienced crew only, no doubt. The wind is light from the SSE, which helps keep it a bit cleaner. There is a risk of thunderstorms, but that's a fair trade for the size.

Thursday the 20th sees the swell holding around 10ft but the period drops a touch to 16 seconds. The wind swings more SE and goes cross-on in the morning, making it a bit choppier and less appealing. The energy is still strong at 4154, but that cross-on wind is a buzzkill.

From Friday the 21st through to Tuesday the 25th, the swell backs off a bit, hovering between 6ft and 8ft. The period stays in that 14-16 second range. The wind is mostly onshore from the SSE or SE, which keeps the surface messy. There are waves, but it's work, not a reward. The energy drops back to moderate, with readings in the 1300s to 2900s. Not a great stretch.

The middle of the week, from Wednesday the 26th to Friday the 28th, looks a little flat and weak. Swell drops to 4ft-5ft, and the energy is weak, bottoming out in the 800s and 900s. It's going to be a slow few days, but the wind is light, so if you're desperate, you might find a clean ripple, but it’s not surf.

Then, things start to fire up again.

Saturday the 29th and Sunday the 30th look like the second standout of the window. On Saturday afternoon, the swell is back to a solid 7ft with the period jumping to 18 seconds, and the energy is pushing strong again at 3133. But the real gem is Sunday morning, the 30th. The forecast is for 7ft of SW swell at 17 seconds, with glassy conditions and a light SE wind. The energy is a solid 2759. That's going to be the cleanest, most powerful day of the whole run. The call is "excellent surf conditions for experienced surfers," which is exactly what we want to hear. This is the day to clear your schedule.

The surf continues through Monday the 31st with a 7ft SW swell and strong energy of 4141. Tuesday the 1st of September has some cross-on winds in the morning, but the size is still there at 8ft.

And then, to round it all out, the long-range tease. Wednesday morning, the 2nd of September, is calling for a 10ft SSW swell with a 17-second period and, get this, offshore NW wind. That's the one we're hoping for, but it's a long way out, so treat it as a promising possibility, not a certainty.

The whole run is at Nipussi (Nyang-Nyang), a heavy reef break that's consistent and exposed. With the size we’re seeing, it’s strictly for the advanced crowd. If you're a beginner, stay well away. The water temp is about average for this time of year, so no surprises there. Keep in mind, with a reef setup and these long-period swells, it could be breaking a bit straight, so pick your lineups wisely. The standout is Sunday the 30th, with Wednesday the 19th as the big and gnarly alternative. If the wind is on it, this set-up with these swells might look more fun for the kite crew, but for us paddle surfers, we want the clean days.

Alright, keep an eye on the sky and the ocean.

Rusty.
