The Lowdown
Alright folks, Rusty here. Let’s get into it. We’ve got a solid run of swell on the cards for Nungas, so get your gear ready.
The first few days kick off with a long-period groundswell that’s packing some serious energy. Saturday 22nd August sees a clean 8ft swell from the SSW with a 16 second period, and the combined energy is a massive 2900. It’s a bit much for the groms, but for anyone with a bit of experience, this is where it’s at. The cross-off breeze keeps things clean, and the water temp is pretty much what you’d expect for this time of year.
Sunday 23rd holds similar size, dropping just a touch to 7ft, but still with that lovely long 15 second period. Morning is the pick with clean conditions. The afternoon gets a little lumpy with a cross breeze, so stick to the early session.
The real standouts, though, are the Friday 28th August and into the first week of September. Friday the 28th sees a 8ft SW swell with a 17 second period and the energy reading hits 3863 – that’s proper, powerful groundswell. The wind is light and cross-offshore, so it’ll be glassy. This is the best on offer for the whole forecast period. It’s big, it’s clean, and it’s consistent for a reef and point setup.
Then, on Tuesday 1st and Wednesday 2nd September, we get another pulse. Wednesday morning (2nd Sept) has a 8ft SW swell, 18 second period, and energy of 3121. Again, cross-offshore wind and clean conditions. Another top-tier session.
There’s a bit of a lull around the 30th and 31st August, with smaller 5ft and 3ft swells, but still rideable. The end of the run into the first week of September drops off in size but stays clean.
If you’re not an expert, steer clear of the 8ft days. For the rest, it’s a great run. Crowds are “sometimes” a thing at Nungas, so you might have company on the peak days.
Alright, that’s the view from here. Stay salty.

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.
