The Lowdown

Alright, Rusty here. Let’s get into it for Nungas.

We’ve got a run of solid, clean conditions kicking off on Friday the 28th of August. This isn’t a small summer dribble; this is a proper groundswell event. The water temp is sitting about average for the time of year, nothing wild there, but the energy in the water is the real story. Friday morning brings a heavy 8ft SW swell with a very long 17-second period – that’s a powerful groundswell. The combined energy is massive at 4161, so there’s serious push behind it. Winds are light and cross-offshore, keeping the lines clean. This is only for experienced surfers though; 8ft with that kind of period is going to be a freight train on the reef and point setup. Crowds are sometimes an issue here, and on a day like this, expect a few locals out.

Friday afternoon drops off just slightly to 8ft at 16 seconds, still excellent, still powerful (3808 energy), but same story – expert territory.

Saturday the 29th is still pumping. Morning sees 7ft SW at 16 seconds (2233 energy), still big and clean. It eases into the afternoon to 6ft at 15 seconds (1610 energy). Still top-notch, but you need to know what you’re doing.

Sunday the 30th is where it gets a bit more manageable for the average good surfer. Morning shows 5ft SW at 13 seconds (933 energy). That’s a very good, clean wave. Afternoon is 5ft (1015 energy) with light winds. This is the standout window for the first weekend – still decent size, but not the absolute heavy stuff.

Monday the 31st is a bit of a mixed bag. The morning is marginal with a long 19-second period on a smaller 4ft swell – that long period can make it weird and fat on the reef, but the afternoon picks up to 5ft at 18 seconds (1697 energy) and cleans up nicely. Good surf for the experienced crew.

We roll into Tuesday the 1st of September with another pulse. 7ft at 18 seconds (2684 energy) in the morning, building to 7ft in the afternoon. Conditions are clean, but the size and period keep this in the expert zone. Wednesday and Thursday stay solid, with 7ft and 6ft SW swell, but the forecast is a bit more marginal on quality – still clean, but maybe not as perfectly shaped.

The second week sees a gradual drop but some real highlights. After a bit of a lull in size, we get to Thursday the 10th of September. The morning is small at 3ft but with a very long 20-second period – that’s weird energy, might be fat. But the afternoon fires up again with a 6ft SSW groundswell at 18 seconds (2109 energy). That’s another excellent, powerful session.

Then, the absolute standout of the whole outlook is Friday the 11th of September. Friday morning hits with a clean 8ft SSW swell at 17 seconds (3674 energy), light offshore winds. This is as good as it gets for an expert wave. Saturday the 12th of September looks like the peak of the whole run. Saturday morning shows a solid 10ft SSW swell at 17 seconds with light winds. The combined energy is 4648. That is a proper, heavy, all-time swell. Only the most experienced chargers need apply. That’s your pick of the whole 16 days, but it’s a long-range call so keep an eye on it.

For the gaps, there’s no dead time here – Nungas has swell pretty much the whole way through, just fluctuating in size. The early days are the biggest, but the middle of the second week holds the real magic for the hardcore crew.

Rusty, signing off.

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.
