The Lowdown
G’day, Rusty here. We’ve got a solid run of surf on the way at Nungas. It’s a reef and point break that’s fairly consistent, and it’s open to the south-west. For a beginner-friendly spot, this is a proper stretch of clean, powerful swell. Water temp is 80°, which is about average for this time of year.
The action kicks off on Wednesday the 19th of August. Morning sees a strong 8ft SW groundswell with a very long 19-second period – that’s proper energy (3626). Winds are cross-off from the ESE at 9 mph, keeping things clean. This is serious, powerful surf for experienced surfers only – over 8ft by the afternoon, so it’s expert territory. The combined energy stays high (3839), and the period is 18 seconds. This is the best of the run: big, clean, and pushing a lot of water. Crowds are sometimes a factor here, so you might see a few others, but the quality will be worth it. Thursday the 20th is the standout if you want that early push – morning swell hits 10ft, from the SW, 16-second period, combined energy of 4174. Still cross-off and clean. This is the biggest of the forecast, and it is expert-only. From Friday the 21st, the swell size drops but stays excellent – 7ft to 8ft through the weekend with 15 to 17-second periods. Winds stay cross-off from the ESE or SE, light to moderate, keeping the waves clean and lined up. Saturday the 22nd and Sunday the 23rd both offer strong 8ft and 7ft SSW swell with 16 and 15-second periods. Saturday stays clean all day, but Sunday afternoon shifts to a crosswind and gets a little choppy.
Moving into the second week, the swell eases but still holds. Monday the 24th has 7ft SSW swell, still clean. By Tuesday the 25th the swell drops to 6ft but the period holds at 15 seconds – still a decent wave. Wednesday the 26th is a smaller, clean 5ft SW swell. Thursday the 27th gets light, with a 4ft SW swell in the morning, but the period jumps to 20 seconds in the afternoon – a very long period groundswell that will wrap around the point beautifully, though a 8ft SW swell returns on Friday the 28th with a 16-second period and light winds, super clean – another good day. Saturday the 29th drops to 6ft with crosswinds and a little chop, so it’s less inviting. Sunday the 30th is clean but smaller at 5ft.
Then on Monday the 31st of August, we get a weird one – the swell is only 3ft but with a massive 22-second period, giving a combined energy of 2152. That’s a lot of energy for a small wave – a classic groundswell that’ll peel perfectly along the point. The real re-up comes on Tuesday the 1st of September: 8ft SW swell at 18 seconds, combined energy of 4754, and clean cross-off winds. That’s the best of the late forecast – a serious, powerful swell for experts. The following days ease down but stay clean and surfable through to Thursday the 3rd of September.
The very long period swells (15-22 seconds) will be best on the point at Nungas since beach breaks can get too straight. The consistent SE cross-off wind keeps it clean most days, and the water stays warm. This is a cracking outlook with a couple of true standouts: Thursday the 20th of August for the big, clean 10ft, and Tuesday the 1st of September for the powerful 8ft re-up. Don’t sleep on the 22-second day on the 31st either – that’s a special one.
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.
