The Lowdown
Alright folks, Rusty here. Let’s get stuck into this one.
We’ve got a solid run of swell on the cards for Nungas, a reef and point set-up that loves a good SW groundswell. The water is sitting at 80°, which is pretty much bang on average for this time of year, so nothing weird going on there.
The first real action kicks off on Tuesday the 11th of August. We’re looking at a solid 10ft swell from the SSW, with a period of 17 seconds – that’s proper long-period groundswell, loads of energy and shape. The combined energy is pumping at 4394 (strong to very strong). Winds are a cross-off SE breeze at 9 mph, keeping things clean. This is big, powerful stuff though – over 8ft, so this is strictly for the experienced crew. Beginners should stay well out of the water. The long period means the waves will be reeling nicely down the point, but the sets will be spaced out, making the paddle out a bit easier if you time it right.
Wednesday the 12th backs off a touch to 6ft, still from the SSW, with a 14-second period. Combined energy drops to 2153 (moderate to strong). Still clean with that cross-off SE breeze. This is still a solid wave, but more manageable.
Thursday the 13th is similar, with a morning 6ft and afternoon bumping to 7ft, both from SSW. The period hangs around 16 seconds, so still plenty of groundswell character. Afternoon winds ease to a light cross-off SSE at 6 mph, making for some glassy conditions.
Friday the 14th through Sunday the 16th sees a consistent run of 6ft to 7ft SSW swell, periods between 15 and 17 seconds. Winds stay light and cross-off. The combined energy hangs around the 1600 to 2400 mark. This is just excellent, clean surf for experienced surfers, day after day.
Monday the 17th drops a little to 5ft-6ft, still clean and cross-off. The energy dips to around 1000-1200, but it’s still a very good wave.
Now, Tuesday the 18th to Friday the 21st of August, the swell kicks back up. Tuesday afternoon sees 7ft, and Wednesday through Friday brings 8ft swell from the SW, with periods of 16-18 seconds. The combined energy is massive, hitting 3831 on Friday afternoon. Winds are still cross-off, but a bit stronger – moderate breeze at times. This is heavy, powerful swell. Unless you’re an expert, give it a miss.
Saturday the 22nd stays solid at 8ft-8ft from the SW, with light cross-off winds. Another great day for the experienced surfer.
Sunday the 23rd drops to 6ft, and then Monday the 24th to Wednesday the 26th of August runs solid 6ft to 7ft SW swell, with periods between 13 and 19 seconds. The longer period on the 26th (19 seconds) will be especially good for the point, with that super-long, lined-up energy.
The standout here is clearly the first day, Tuesday the 11th of August. That 10ft SSW groundswell with 17-second period, clean cross-off wind, and pumping energy is the best on offer. If you’re experienced, you’d be a fool to miss it. The run from Friday the 21st to Saturday the 22nd is also a highlight, with 8ft SW swell and light winds. Crowds are listed as “sometimes,” so you might get a few out, but with that much swell, it’ll spread out.
Overall, this is a cracking 16-day window for Nungas. No gaps, just wave after wave.

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.
