The Lowdown
Alright, let’s get into it.
The next couple of weeks are going to be a bit frustrating if you’re looking for clean, classic waves. There’s plenty of swell on the cards, but the wind is going to be the main character here, and not in a good way. For the most part, we’re looking at a persistent cross-onshore flow that’s going to chop things up and make it hard work.
Right off the bat, things aren't great. On the 18th, Nyang-Nyang has some solid 6ft SW groundswell with a 16-second period, but the ESE wind is blowing 12 mph cross-shore and it’s just not holding together. The water temp is at 78°, which is only about 1° cooler than average for this time of year, so nothing crazy there, it’s just standard. The energy is moderate with a combined reading of 2639, but the surface is a mess. It’s not worth paddling out for.
The next several days follow the same pattern. The swell stays up, even pushing to 10ft on the afternoon of the 19th and into the 20th, but the wind stays stuck in that cross-on direction with 16 mph speeds. The energy is strong, readings in the 4000s, but it’s a washing machine out there. I wouldn't bother until things settle.
There’s a real gap here with zero quality options from the 18th through the 29th. It’s a long stretch of chop and frustration. We see a brief flicker on the 20th afternoon with a cross-shore wind, but it’s still just at 8ft and looks marginal.
Then, finally, we get a bit of a change on Sunday the 30th. The wind swings around to the south, blowing a light 3 mph in the morning. That’s the first taste of clean surf we’ve seen in almost two weeks. The swell is a strong 8ft from the southwest with an 18-second period. That’s a proper groundswell. The energy is strong too, reading at 3519. The light wind is the key here; it’s going to make all the difference. This is the standout morning of the whole run. It’s a reef break and it’s fairly consistent, so it should be holding good shape. This is the one to circle.
But, just as quick as it comes, it’s gone. We’re back to the cross-on wind by the afternoon with 9 mph, and the rest of the run is a letdown. The first of September brings some serious size, with 10ft swells and strong energy in the 5000s, but the wind is back onshore and it’s just going to be a big, blown-out mess. The 2nd is the same story. It’s a lot of water moving but no quality on the surface.
So, the takeaway here is: hold out for Sunday the 30th. That’s the morning to be out there. The rest of the window is a write-off for clean surfing. It’s a shame, but that’s the way it goes sometimes.

Very soon you may start to choose your surf days based on the wave energy alone combined with our forecast of favourable offshore wind conditions. Our star ratings will help here and of course you will also find the usual wave height and period predictions on our surf forecasts as well as a full break down of the swell components under our advanced users option (to reveal that, click the little Einstein character under the tide times).
Further information to help with frequently asked questions about our surf forecast for Nyang-Nyang may be found under the help tab on the top menu and also by moving your mouse over the question marks on the surf forecast table itself. Please always bear in mind that the forecast is for near-shore open water and local factors at each surf break influence the actual breaking wave height, such as the beach / reef profile, water depths offshore and shelter.
