The Lowdown
Alright folks, Rusty here. Let’s break down what’s cooking at Nungas over the next couple of weeks. This is a reef and point set-up, and it’s fairly consistent, so we’ve got plenty to work with.
The overall pattern is a long run of persistent SSW to SW groundswells. It’s not all perfect, but there are definitely some days that will have you feeling alive. The water temp is sitting right around 79.2°F, which is bang on average for this time of year, so no shocker getting in.
The first solid action kicks off Monday the 24th of August. We’ve got a clean 7.2ft SSW swell rolling in with a 15-second period (combined energy at 2199). It’s a bit cross-off with a 9 mph breeze, but those long-period lines will be wrapping nicely around that point. This swell is a touch over the 5ft mark, so get it while it’s still manageable.
Tuesday the 25th sees the swell dip a little, but it’s still clean with 4.6ft to 5.9ft from the SW. The best window in this first week without a doubt is Friday the 28th of August. That morning, it’s a standout: 8.2ft of SW groundswell with a 17-second period (combined energy of 4343). The wind is a gentile cross-off breeze making it clean. Now, that 8.2ft is solid; this is for experienced surfers. The 17-second period means proper groundswell – it will stand up and wall, but on a point reef like this, it’ll be absolutely world-class.
After Friday, the weekend of the 29th and 30th is still very good, with clean 6.9ft dropping to 4.6ft cross-off conditions. That Sunday the 30th is a nice day for a longer board if you want a break from the heavy stuff.
Things get very clean again for the start of September. Monday the 1st and Tuesday the 2nd are top-tier. On Monday the 1st, we’re looking at 6.6ft to 6.9ft of SW swell with 17-second periods and light to gentle cross-off breezes. The energy is strong at 2371 to 2429. Again, this is for the more capable crew.
The second week stays active. Into the week of September 3rd through the 8th, the swells hold at a robust 5.2ft to 7.2ft, mostly from the SW with clean conditions. The best of this back half looks to be the morning of Tuesday the 8th of September: 6.2ft, 14-second SW groundswell with a light 6 mph cross-off breeze (combined energy at 1552). It’s clean and punchy.
A bit of a heads up on the crowds: this spot can get busy sometimes, so if you want a quieter paddle, aim for the early starts. On the bigger days (over 6.6ft), the experienced surfers will be the main show. The inconsistency isn’t a problem here – this run is fairly consistent right through.
Alright, that’s the look. Stay safe out there, watch the sets on those bigger groundswell days. Get on it.

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.
