The Lowdown
Alright, Rusty here. Let's get into it.
We've got a solid run of south-west groundswell on the cards for Nungas, a reef and point break that's fairly consistent. The water temp is sitting about average for this time of year. The first proper surf kicks off Friday, August 7th, with a generous 7.2ft SSW swell at 16 seconds. That long period between sets means the waves will have heaps of energy and shape, and the cross-off wind from the SE will keep things clean. The combined energy of all swells directed here is a strong 2721. It's a good start, but the real standout begins on Saturday morning, August 8th, with the swell bumping up to 8.2ft, still from the SSW, with that same 16-second period. The wind stays clean, and the combined energy is 3062. This is excellent for experienced surfers; the size and power make it a proper session for those who know what they're doing. Crowds are possible here, so get in early.
The swell hangs in the 6.6ft to 8.2ft range through the following week, with the wind staying mostly cross-off or light, keeping the face clean. Monday afternoon, August 10th, sees a spike in energy to 4276, with a 8.2ft SSW swell and an 18-second period—that's very long period groundswell, meaning it will stand up nicely on the point. The best of the first week is likely Tuesday morning, August 11th, with a 9.8ft SSW swell at 17 seconds. The combined energy is a massive 4447. That's a big, powerful swell, and with the clean cross-off wind, it's going to be an epic session for experts only. Remember, over 8.2ft is for experts. The swell then drops back a touch, but the quality remains high through the week.
The window from August 15th onward still has surf, but it's a little more inconsistent in size. The morning of Saturday, August 15th, is a smaller 4.9ft, then a 6.6ft swell pushes in on Sunday, August 16th, but the wind picks up from the ESE at 12 mph, making it a bit trickier. The combined energy drops to 2020. The real blazer comes in on Wednesday, August 19th, with a 8.2ft SW swell at 18 seconds and a combined energy of 4649. The wind is light from the SSE, making it cross-off and clean. That is a standout long-range call. Then Thursday, August 20th, pushes up to a 9.8ft SW swell at 17 seconds, with a combined energy of 5160 in the afternoon. That's another massive, clean session for experts. The run finally fades out with smaller, 6.6ft to 7.9ft surf through Saturday, August 22nd.
So, the standout pick is Tuesday morning, August 11th. The energy is high, the swell is solid, the wind is clean, and it's a classic SSW groundswell matched to the optimum direction for the point. That's your best bet. The long-range standout is Wednesday, August 19th, for the same reasons—just a bit less certain that far out, but it looks promising.

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.

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.
