The Lowdown
Alright, Rusty here, let’s talk about what's comin' up for Nyang-Nyang.
It’s gonna be a long wait for any kind of decent surf, that's for sure. For the next week and a half, the wind is mostly onshore or cross-onshore and the wave energy is massive but messy. The combined energy from Wednesday August 19th afternoon is a massive 4660, which is very strong, but with a 16 mph cross-onshore ESE blowin’ it’s just choppy and poor. That pattern hangs around for days on end.
Through the end of August and into the very start of September, there’s a whole lot of nothing good to get excited about. The swell is solid, over 8 ft some days, but it’s all trashed by that persistent cross-onshore wind. This reef at Nyang-Nyang really needs that south-west groundswell to line up with the break, but it’s just getting chopped up. For the best part of 10 days, every entry says poor surf conditions. I wouldn’t even bother paddling out.
Now, if you’re holding out for a glimmer, there’s a sniff of something better on the morning of Friday August 28th. The wind finally swings to light offshore from the SSE at 6 mph, which is a major positive. The swell sits at 8 ft from the SW with a long 16-second period. The combined energy jumps back to 3278, so it’s a powerful, clean-looking groundswell. The catch is the forecast calls it “marginal surf forecast or questionable tide conditions”, so it’s not a guaranteed home run, but if you pick your tide right, this is your standout window. Nyang-Nyang is an advanced reef break, so hold onto your board.
After that, the wind goes a little more cross-onshore again, and while there’s still some size, it’s back to being average. The period drops off into the second week, and the energy fades to the low 1000s. By September 3rd, you're looking at 5 ft swell with a 15-second period and a gentle cross-onshore breeze, which is just fair. Nothing to write home about.
Overall, this is a frustrating outlook. The only real standout is that Friday the 28th morning. The rest is blown-out, strong onshore crud. Hang tight and keep an eye on the sky.

Information about the Nyang-Nyang Surf forecast
The above surf forecast table for Nyang-Nyang provides essential information for determining whether the surfing conditions will be good over the next 16 days. A general guide to surfing at Nyang-Nyang can be found by selecting the local surf guide option on the grey menu. Our Nyang-Nyang surf forecast is unique since it includes wave energy (power) that defines the real feel of the surf rather than just the height or the period. If you surf the same spot (Nyang-Nyang) regularly then make a mental note of the wave energy from the surf forecast table each time you go. 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.
