The Lowdown
G’day, Rusty here, and we’ve got a solid run of surf coming up at Nungas. This spot is a reef and point setup, pretty exposed to the southwest swell, so it’s gonna be firing on and off for the next couple of weeks. The water’s sitting at 80°, which is pretty much what you’d expect for this time of year, nothing unusual there.
We kick off on Sunday the 30th of August with clean, cross-off conditions and a nice 5ft southwest swell, period around 13 seconds. The wave energy is moderate (933), and the surf is clean and very good. Monday the 31st keeps it ticking over with a 4ft to 5ft swell, but the period jumps up to 18–19 seconds – that’s a long-period groundswell. The energy climbs to 1465–1660 (moderate), and while the cross-off wind keeps things clean, that long period might make the waves break a bit straight at the beach. Nungas is a reef and point though, so it should handle it well.
Tuesday the 1st of September sees the swell building to 7ft, with the same long period, and the energy jumps to the upper 2000s (moderate). The wind is still cross-off, and the morning is clean, but it’s marginal for tide. The afternoon though, the swell drops a touch to 6ft from the SSW, and the conditions are excellent for experienced surfers – that’s a standout session. Wednesday the 2nd keeps that 7ft swell going, with the morning again clean but marginal, then the afternoon offering excellent waves for the crew who know what they’re doing.
By Thursday the 3rd, the swell eases back to 5–6ft, still clean, but the energy drops to 1265–1540 (moderate). Friday the 4th is smaller, around 4–5ft, but still clean and fun. Saturday the 5th sees a little bump back to 5–5ft, with some clouds around but the cross-off wind keeping it tidy.
Now, Sunday the 6th of September is where things get interesting. The swell pushes up to 8ft from the SSW, with a 17-second period, and the energy is strong (2815). The morning is excellent for experienced surfers, but the afternoon gets a bit of cross-chop from the cross wind. Monday the 7th keeps the 7ft swell, with the morning clean and excellent for the more skilled surfers. The rest of the week from Tuesday the 8th to Thursday the 10th stays solid, with swell heights between 6ft and 8ft, and the energy staying in the moderate to strong range. The wind is cross-off again on Thursday, giving clean waves.
But the real standout is coming up on Friday the 11th of September. We’ve got an 8ft southwest swell with a 19-second period, and the energy is cranking at 5161 (strong to very strong). The wind is a light cross-off, making it clean. This is excellent for experienced surfers – a proper session. Saturday the 12th is even bigger, with 10ft swell in the morning and 8ft in the afternoon, both clean with light winds. The energy is 4826–3877, still very strong. That’s expert territory, but if you’re confident, it’ll be pumping.
The following week, from Sunday the 13th to Monday the 14th, keeps the swell solid at 7ft to 10ft, with clean conditions and excellent surf for experienced surfers. The energy stays high, around 3193–4699. The waves are big, so this is not for the groms – it’s for the crew who can handle serious power.
Crowds can be a thing here sometimes, so if you’re looking to get a clean one, aim for the early morning sessions, especially on the standout days. The consistent run of southwest swell and light cross-off winds means Nungas is going to be a good bet for the next couple of weeks.
Stay safe out there, and paddle hard.
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.
