The Lowdown
Alright, Rusty here. Let’s have a look at what we’ve got cooking.
Alright, the pattern is a long, consistent run of south-west groundswell heading our way. There’s no real gap at the start – we’re straight into it. The water temp is sitting at 80°, which is bang on average for this time of year, so the water’s feeling like a warm bath. The standout period is definitely the first few days, with a big pulse of energy arriving.
Wednesday 9th September kicks things off proper. Morning at Nungas is looking solid. We’ve got a good 8 ft of swell rolling in from the SSW, and this is a very long-period groundswell at 16 seconds. There’s a heap of energy in the water – the combined energy reading is a strong 3504 – so you’ll feel that push. The wind is a steady 9 mph cross-off from the SSE, which will keep the faces reasonably clean. This is solid, powerful stuff, so it’s one for the experienced crew. The swell is over the 8 ft mark, so this is expert territory. The period is long, meaning the sets will be well-spaced, and at a reef and point set-up like Nungas, it should handle that long-period energy beautifully. The crowds can be around sometimes, so expect some company, but the quality on offer will be worth it.
Through Thursday 10th and Friday 11th, the swell eases a touch but stays in the very good range, still with that clean cross-off wind. Saturday the 12th is a bit smaller but still clean, a good option if you want a slightly mellower wave.
For my pick of the week, it’s a toss-up between the opening morning on Wednesday the 9th, and then a real sneaky good window later. If I have to call it, I’m pointing you to Sunday morning the 13th of September. You get a solid 6 ft wave, but here’s the kicker: the period jumps to 18 seconds. That’s a very long-period groundswell. The combined energy pushes up to 2579. The wind is a light cross-off at 9 mph. South-west swell direction is right in the sweet spot for this break. It’s less heavy than the Wednesday but still powerful and clean – a beautiful balance of size and shape.
Looking further ahead, the swell stays consistent, with a few bumps in energy. Saturday 19th September sees a drop in size, down around 5 ft to 6 ft, with very light 6 mph winds. That’s a good day for a smaller board or for someone wanting a more manageable session.
Then, towards the back end of the window, things fire up again. From Sunday 20th right through to Wednesday 23rd September, we see a steady pulse of 7 ft to 8 ft SSW swell with excellent energy readings. But the real beast shows up on Thursday 24th September. The morning session is huge: 10 ft of SSW swell, very long 17-second period, and the combined energy hits a massive 5177 – that’s a seriously strong event. The wind is a light 6 mph from the SE, giving a clean cross-off look. That’s going to be a huge day for big-wave chargers, and it’s still two weeks out, so treat it as a promising, heaving option. The wind swings southerly in the afternoon, which will put a bit of a cross texture on the surface, so the morning window is the one to target.
So, to sum it up: it’s an excellent run. The best early call is Sunday the 13th for that classic long-period cleanliness. The long-range standout is Thursday the 24th, but only if you’ve got the skills for serious size. The wind stays favourable for the most part, and the consistency is high. Get amongst it.
Rusty.

Information about the Nungas Surf forecast
The above surf forecast table for Nungas provides essential information for determining whether the surfing conditions will be good over the next 16 days. A general guide to surfing at Nungas can be found by selecting the local surf guide option on the grey menu. Our Nungas 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 (Nungas) 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 Nungas 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.
