The Lowdown

Righto, let’s have a look at what’s coming for Nungas over the next couple of weeks. This is a reef and point setup that gets a good amount of swell, and from what I’m seeing, there’s plenty to get excited about.

The pattern is set to kick off on Friday the 21st of August. We’ve got a solid groundswell arriving with a 7ft swell out of the SW, and that swell period is a very healthy 15 seconds. The combined energy is strong at 2269, so there’s plenty of grunt in the water. Winds are light and cross-off from the ESE, which will keep things clean. This is excellent surf for experienced surfers – anyone else will find it a bit of a handful. The water temperature is about average for this time of year, so no nasty surprises there. Crowds are possible at Nungas, so get in early.

That Friday afternoon, the swell pulses up a touch to 8ft from the SSW, period stretching to 17 seconds and energy surging to 3229. The wind stays cross-off, but the tide or conditions might be a bit tricky, so the morning session is the standout.

Saturday the 22nd looks mint. Morning brings 8ft SSW groundswell with 16 seconds and strong energy at 2900. Cross-off wind again, and it’s glassy clean. This is classic Nungas – powerful lines wrapping around the point. It’s going to be excellent for experienced surfers. The afternoon holds 7ft with similar conditions.

Sunday the 23rd keeps the run going. A 7ft SSW swell, 15-second period, cross-off breeze, clean waves. The combined energy is still solid at 2106. Another excellent morning for those who can handle it.

Monday the 24th is a bit more marginal in the morning with a 7ft swell, but the afternoon cleans up nicely with 7ft, 16-second period, and excellent conditions. By Tuesday the 25th, the size drops to 5ft in the morning, but the quality is still very good, and the afternoon bumps up to 6ft from the SW.

We then get a bit of a taper mid-week. Wednesday the 26th sees 6ft SSW swell, dropping to 4ft by Thursday the 27th. Still clean, still fun, but the energy is easing off.

Then, hold onto your boardies. Friday the 28th of August, a new pulse arrives. It’s a bit tricky with cross-shore wind, but the swell size jumps to 10ft from the SW with a 17-second period and massive energy at 4554. This is a big, powerful groundswell. The wind is cross, so there will be some bump, but for the experts who know the break, it’s going to be a serious session. Saturday the 29th cleans up again. 7ft SW with 16 seconds and cross-off winds. Energy is high at 2322. This is a proper weekend.

After that, we roll into a quieter spell from Sunday the 30th to Monday the 31st, with waves in the 4ft to 6ft range. Still very good conditions in the mornings, but the energy drops right down.

But here’s where it gets truly exciting. Tuesday the 1st of September, a massive swell lights up. The morning kicks off with 7ft from the SW, period at 19 seconds, and energy at 3414. The wind is light cross-off. This is a groundswell of rare quality for Nungas. The afternoon holds at 8ft with 18 seconds.

Wednesday the 2nd keeps the fire burning with 8ft SW, 17 seconds, light winds, and excellent conditions for experienced surfers. The wave energy is strong at 2845. Thursday the 3rd is solid again, 7ft SW, 15 seconds, clean.

And then, for the absolute standout of the entire forecast… Friday the 4th of September. The morning has a 5ft SSW swell but look at that period: 21 seconds. That is a very long-period groundswell. The combined energy is 3729 – moderate but highly organised. The wind is light and cross-off. This is a point break dream. By the afternoon, the swell size jumps to 8ft from the SSW with a 19-second period and energy slamming in at 6423 – that’s very strong. The wind stays light. It’s clean, it’s powerful, and it’s going to be world-class for those who can paddle into them.

Saturday the 5th of September finishes the run with 10ft SSW, 17 seconds, strong energy at 4272, and clean cross-off winds. A massive, expert-level day to end it.

Overall, there are a couple of days in the gap around the 27th to 31st where it’s smaller, but this is a stellar run. Nungas is a fairly consistent spot and it doesn’t stay flat for long around here – but this is a true winning streak. The standout is clearly Friday the 4th of September into Saturday the 5th, but the whole first week from the 21st to the 25th is also pure gold.

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.
