The Lowdown
Alright folks, Rusty here. Let’s get into it.
We’re looking at a patchy start, but the back half of this forecast has some serious teeth. The first solid option doesn’t show up until Monday, July 20th, with a building SW groundswell. Nungas is a reef and point setup, fairly exposed to the SW, and it’s fairly consistent when it does get swell. The water is sitting at 81°, which is pretty much normal for this time of year, so no surprises there.
The real standout looks like Monday afternoon, July 20th. The swell bumps up to 7ft from the SW, with a solid 17-second period—that’s proper long-period groundswell. The wave energy is strong at 2538, and with a gentle cross-off breeze, it’s going to be clean. This is one for the experienced crew, as it’s pushing into the bigger stuff. The long period means Nungas, being a reef and point, should handle it beautifully, with better-shaped waves and longer rides. Crowds are possible here, so keep an eye out.
Things drop off a bit through the middle of the week, with smaller, weaker swells and marginal conditions. The weekend of July 26-27 is pretty flat, with energy dropping to 193, so don’t bother.
Then, the second week shows a real pulse. Thursday, July 30th afternoon is a sleeper hit: 4ft from the SW, but with a very long 19-second period. The energy is strong at 1460, and it’s a clean, cross-off breeze. This is a classic long-period groundswell that will wrap in nicely at the point. Beginners might find it a bit tricky with the long gaps, but for anyone with a bit of experience, that’s the call.
The biggest swell of the run hits Sunday, August 2nd. We’re looking at 8ft from the SW, 16-second period, and massive energy at 3605. That is expert-only territory. The wind is light, so it’ll be glassy, but this is a serious, powerful swell. If you’re not comfortable in big, heavy water, sit this one out. The following Monday, August 3rd afternoon, still holds strong at 7ft with a 19-second period and energy peaking at 4843, but again, that’s for the big-wave crew.
Overall, the best bet for the average surfer is the clean, long-period groundswell on Thursday July 30th. For the experienced, the big sessions on August 2nd and 3rd are worth marking on the calendar.
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.
