The Lowdown
G’day, I’m Rusty, and I’ve been staring at the charts for Nungas – and mate, this is a bloody run of solid, consistent south-west groundswell that’s got the place firing for the next couple of weeks. It’s a reef and point setup that’s fairly exposed to the swell and it loves it from the SW – exactly what’s lining up. The water temp is sitting at 80.1°F, pretty much bang on average for this time of year, so no surprises there.
The action kicks off on Sunday afternoon, the 6th of September. We’ve got a 7.2ft SSW swell with a very long 17-second period, carrying a heap of energy (2764). That’s proper groundswell, and with a cross-off breeze, the faces are going to be clean and lined up. It’s a bit meaty – over 6.5ft – so this one’s for the experienced crew. The crowd factor says “sometimes,” so you might have a few locals out, but it’s not a zoo.
Monday the 7th and Tuesday the 8th keep the quality high. Monday morning drops a touch to 6.9ft SSW, still with a solid 14-second period (1857 energy), and the cross-off wind stays gentle. Tuesday afternoon is a ripper: 5.2ft but the period jumps to 18 seconds, pushing the energy up to 3094 – that’s a lot of punch in a clean, long-period line. The reef and point will love that.
Wednesday the 9th is the standout for the first week. We’re looking at 8.2ft SSW swell on Wednesday morning with a 16-second period and a massive 3504 energy reading. That’s the biggest swell of the run, but it’s over 8.2ft – expert territory only, no question. The wind is still cross-off and light, so the waves will be bowling. If you’re not confident, give it a miss, but for the chargers, this is the session.
We roll into Thursday and Friday the 10th and 11th – still solid. Thursday morning has 6.2ft SSW at 15 seconds (2192 energy) and clear skies. Friday morning drops to a light 6 mph cross-off, making the 6.9ft SW swell (2185 energy) glassy and smooth. That’s a beautiful window for experienced surfers who want power without the max-size chaos.
The weekend of the 12th and 13th is still good, but the energy eases a bit. Saturday morning is 5.2ft SW at 15 seconds (1605), still clean. Sunday the 13th afternoon brings a bit of a spike: 6.2ft SW with an 18-second period, energy back up to 2949 – another long-period gem for the point.
Into the second week, from Monday the 14th onward, the consistency holds but the wind picks up at times. Monday afternoon has 6.9ft SW but with a moderate 12 mph cross-off, still clean but a bit more breeze. Tuesday the 15th is a bit smaller at 5.9ft, and the energy drops into the 1400-1500 range – still surfable, but less punchy.
The real highlight in the second week lands on Saturday the 19th. Saturday morning brings 7.5ft SW swell with an 18-second period and a massive 3415 energy reading. The wind is a gentle 9 mph cross-off. That’s a proper groundswell for the point – long lines, heaps of push, and clean. If you’re an experienced surfer, mark that date. Saturday afternoon is just as good with the same size, a 17-second period, and the wind dropping to a light 6 mph – glassy conditions, unreal.
Sunday the 20th keeps the run going: 7.2ft SW, 16-second period, still cross-off and clean. After that, Monday the 21st fades to 5.6ft SW with 15 seconds and energy down to 1220, and the wind swings cross-shore, making it a bit choppy. The run has a solid finish, but that’s the tail end of the goodness.
Overall, Nungas is the only break on offer, and it’s serving up two weeks of reliable, clean, south-west groundswell. The best of the best are Wednesday the 9th for the biggest, punchiest swell, and Saturday the 19th for a slightly more manageable size with glassy winds. Get out there.

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.
