The Lowdown
Alright folks, Rusty here. Let’s have a look at what’s shaping up.
First thing you need to know: the water at Nungas is sitting at 80°, bang on average for this time of year, so no surprises there.
The pattern starts with a solid pulse of SW groundswell already rolling in. Saturday the 29th is the first call, and it’s a ripper for experienced surfers. We’re looking at 7ft of SW swell with a very long period of 16 seconds, so the energy is pumping (combined energy of 2233). That’s proper groundswell, and with a steady cross-off breeze from the SE at 9 mph, the reef and point setup at Nungas will be grooming out clean. The period is long enough to hold shape, and this break is fairly exposed to the SW swell direction, so it’s handling it nicely. Just be aware, with swell over 5ft, it’s pushing into intermediate territory, and at 7ft, it’s really for the confident crew. Crowds are possible here – it’s a spot that can get busy sometimes.
The standout of the whole run? Saturday the 12th of September. That morning and afternoon are looking mint. Swell hits 8ft from the SW, period still a solid 16 seconds, and the combined energy jumps to 2954. Wind is light cross-off from the SSE at 6 mph, so it’ll be glassy and clean. This is proper, punchy groundswell for the point and reef, and the wave quality is excellent for experienced surfers. If you can wait, that’s the one to circle.
The shoulder days are still good. Sunday the 30th drops to 5ft but with a 13-second period, nice and clean with light breezes – a good option for intermediate surfers. Monday the 31st sees a bit of chop picking up, but the swell is still there. Tuesday the 1st of September bumps back up to 7ft with 18-second period, but the wind is a bit stronger at 12 mph, so not as clean.
Through the first week, the swell stays consistent, with the best clean windows on Wednesday the 2nd, Saturday the 5th, and Sunday the 6th. The 9th, 10th, and 11th all offer solid 6ft to 6ft SSW swell with 16-second periods and clean cross-off winds – very consistent, good energy.
But the real peak is that Saturday the 12th and into Sunday the 13th. Sunday shows 8ft of SW swell, very long period, with light SE winds. The combined energy hits 3288 on the afternoon – that’s strong wave energy. It’s a long-range standout, so keep an eye on it, but it’s looking promising.
No gaps here – the surf is on from the start right through the 16 days. Nungas is the only break in the mix, and it’s handling the swell well. For the bigger days, think reef and point breaks over beach breaks, as the long period can make it a bit straight at the beach.
Right, get out there and enjoy it.
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.
