The Lowdown

Alright, folks, Rusty here. Let’s break it down.

We’ve got a solid run of surf on the cards at Nungas, a reef and point set-up that starts pumping from Thursday the 27th of August and keeps the energy going right through the 16-day window. The winds are predominantly cross-offshore, which is a real treat for this spot, keeping the surface clean and lined up. The water temp is about average for this time of year, so just your usual wetsuit or spring suit, nothing crazy.

The kick-off on Thursday morning is a clean 4ft SW groundswell with a long 16-second period, delivering moderate wave energy (932). It’s a gentle start, but the quality is there – perfect for a beginner to get amongst it. By Friday the 28th, things step up big time. The morning delivers a 8ft SW swell with a 17-second period, and the combined energy jumps to 4343 – that’s strong, powerful surf. This is expert territory; the size and the long period will make it a handful at the point, but for those with the skills, it’s going to be a standout session. The wind is light and cross-off, keeping the face clean. Saturday holds solid with 7ft SW, and Sunday eases into a very clean 5ft.

Monday the 31st sees a new pulse of very long-period SW groundswell at 19 seconds, but the height is only 4ft in the morning. The energy is moderate (1391), but that long period means it’ll wrap in nicely. The afternoon picks up to 5ft with 18 seconds – still a beautiful, clean wave. The whole first week is a treat, with consistent size and that favourable cross-off breeze.

There’s a bit of a lull in the middle of the second week, with smaller swells around 4ft to 5ft, but the wind stays light. Then, come Sunday the 6th of September, the swell kicks back in. A 7ft SSW groundswell with a 16-second period arrives, and by the afternoon it’s 7ft. The energy is strong (1953 to 2123) and the wind is light and cross-off – this is another prime window for experienced surfers.

The run continues into the second week of September. From the 7th to the 11th, we’re looking at consistent 6ft to 8ft SW and SSW groundswells, with periods in the 14 to 16-second range. The wind stays cross-offshore, sometimes light, sometimes a gentle breeze. The energy climbs back up to strong levels (over 2000), and the morning of the 9th of September is a real standout: 8ft SSW at 16 seconds, with light cross-off wind and a combined energy of 2821. This is a top-tier morning for the experienced crew.

The standout is Friday the 28th of August morning. That 8ft SW groundswell with a 17-second period, clean cross-off wind, and strong energy (4343) is as good as it gets at Nungas. Second best is the morning of the 9th of September – 8ft SSW, 16 seconds, light wind, and strong energy (2821). That’s a belter for the experts.

No crowds to worry about at Nungas, it’s a fairly consistent break that handles the size well. The long-period swells favour the reef and point here, so it’s not going to close out. Just be aware, when the swell is over 8ft, it’s strictly for the experienced.

Rusty out.

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.
