The Lowdown
Alright, this is Rusty, and I’m looking at the next couple of weeks for Nungas. This spot is a reef and point set-up, exposed to the south-west, and it’s looking like a solid run of surf is on the cards.
We’ve got a little bit of a wait, but nothing too painful. The action kicks off on Sunday the 30th of August. The water’s sitting at 80°, which is pretty much spot on for this time of year, so nothing weird there.
Sunday afternoon we’re looking at a clean 5ft of swell from the south-west, with a 13-second period. The wind is a light cross-offshore breeze, which should keep the lines tidy. The combined energy is moderate at 934. For a beginner-friendly spot, this is a really nice, mellow start. It’s decent, but not the standout.
The real standout, the one you’d be a fool to miss, is the window from Wednesday the 2nd of September afternoon through to the end of the first week. Wednesday afternoon, the swell jumps to 7ft from the south-west, with a 16-second period. That’s a proper groundswell, and the combined energy is strong at 2558. The wind is a gentle cross-offshore, keeping it clean. This is excellent for experienced surfers. The swell is pushing over 7ft, so it’s not for the beginners, but for anyone who knows what they’re doing, this is magic.
We’ve got a few days of solid, clean surf after that, with the swell holding around 6ft to 7ft, staying clean with that cross-off wind. The morning of Tuesday the 8th of September, the period jumps to 20 seconds, which is a very long period groundswell. That’s going to be a bit too straight for a beach break, but at a reef and point like Nungas, it’ll be threading through perfectly. The energy is very strong at 3063.
Then, from the 9th of September onwards, the swell gets bigger. Wednesday morning we’re at 8ft from the south-south-west, with a 16-second period. Combined energy is a massive 4608. The wind is a gentle cross-shore, which will put a slight chop on the face. This is still excellent for experts, but the size is getting serious. By Thursday the 10th and Friday the 11th, we’re still seeing 8ft, but the wind swings back to a clean cross-offshore. That’s the pinnacle: big, powerful, and clean. The energy values are in the four-thousands, showing very strong wave energy.
The second week, from the 13th of September, the energy starts to dial back. Sunday the 13th is still a solid 6ft and clean, and Monday the 14th is back to 7ft with a light cross-offshore breeze. It’s all good, but it’s a step down from that mid-week window.
That Wednesday afternoon the 2nd through to the end of the first week, and especially the big, clean days on the 10th and 11th of September, are the ones to circle. Crowds are a possibility here, but with a run this good, it’ll be worth 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.
