The Lowdown

G’day, I’m Rusty, and I’ve been watchin’ the charts for Nungas. This is a reef and point setup, good for beginners, and it’s fairly consistent. We’ve got a solid run of surf ahead, but it’s a bit of a slow start tomorrow morning. The water temperature is sittin’ at 79°F, which is about average for the time of year.

The action really starts to crank from Wednesday afternoon. The swell is 5ft from the SW with a very long period of 15 seconds, and the combined energy is moderate (1359). The wind is a gentle cross-off breeze from the SSE, so the waves will be clean. It’s a solid afternoon for experienced surfers, but with that long period, it’s a proper groundswell — Nungas being a reef and point, it’ll handle that beautifully.

Thursday cranks up a notch. Morning swell hits 7ft from the SSW, period 18 seconds, and the energy is already strong (2768). The wind is a moderate cross-off from the ESE, still clean. By afternoon, it’s 7ft with a 17-second period, and the energy is even stronger (2731). The wind backs off to a gentle cross-off from the SSE. This is excellent, experienced surfer territory.

Friday and Saturday keep the momentum going. Friday morning has 7ft from the SSW at 16 seconds, energy at 2706, with a gentle cross-off. Saturday morning is 8ft, same direction and period, with energy climbing to 3278. The wind stays gentle and cross-off from the SE. Saturday afternoon is a standout — 8ft, 16-second period, and the wind drops to a light breeze from the SSE at 6 mph. That’s glassy, clean conditions for the bigger swell.

Sunday stays solid, with 8ft and clean cross-off winds. Monday is a bit of a mixed bag — morning drops to 5ft, but the period is 20 seconds, and the energy is still strong (3106). The wind is a gentle cross-off from the SSE. The afternoon sees a big jump back to 8ft from the SSW, 19-second period, and the energy is very strong (5043). The wind switches to a cross-shore from the S, which might introduce a little chop, but it’s still surfable.

Now, the real standout is coming up on Tuesday, 11th August. Both morning and afternoon have 10ft from the SSW at 17 seconds, with energy at 4552 and 4714 — that’s very strong energy. The wind is a gentle cross-off from the SSE, keeping it clean. This is only for experts, but for those who can handle it, this is the best session of the whole outlook. The swell is big, the period is long, and the wind is perfect. Nungas will be firing.

The rest of the second week has consistent surf, mostly 5ft to 8ft, with clean conditions and gentle winds. The crowd factor is “sometimes” at Nungas, so you might have company, but it’s not a circus. The swell direction stays SW to SSW, which matches the optimum, so the waves will be well-shaped.

After the 17th, the swell drops a bit, but there’s still decent waves on offer. The 19th of August sees another pulse — 8ft from the SSW, 17-second period, and energy at 4255, with clean cross-off winds. That’s a late reward for those who wait.

All in all, the best session is Tuesday, 11th August — big, clean, expert-only surf. The whole 16-day run has little downtime, so 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.
