The Lowdown
Alright, let’s get into it. The long-range charts are showing a solid stretch of groundswell heading our way, and Nungas is the spot that’s got my attention for the next couple of weeks. It’s a reef and point set-up, fairly consistent, and it loves a good SW swell. This isn’t a day for the learners though; we’re looking at quality waves for those who know what they’re doing.
The action kicks off on Wednesday the 9th. We’ve got a strong pulse of SW groundswell at 8ft with a long 16-second period. That’s proper energy, with a combined energy reading of 3504, and it’s clean with a light cross-off breeze. It’s going to be on the bigger side, so only the experienced crew should be out there. The water temp is about average for this time of year, so it’s not a shock to the system.
We’ll see a slight dip on Thursday the 10th, but it’s still very much rideable. The swell drops to around 6ft to 7ft, still from the SW with that long-period goodness. The wind stays cross-off, keeping the face clean, though the tide might make it a bit more challenging to find the perfect one. It’s still a good day, but that Wednesday was the standout.
Through Friday the 11th and into the weekend, the swell eases back a touch, sitting in the 5ft to 7ft range. The period remains long, in the mid to high teens, which keeps those waves with plenty of push. Winds stay light to moderate and cross-off, so the conditions remain clean and inviting. It’s consistent, fun surf, but not quite the size of the opening day.
Sunday the 13th is another one to circle. The swell jumps back up, reaching 8ft in the afternoon with a very long 18-second period. The energy reading jumps up to 3988, and with light offshore winds, it’s going to be firing. This is premium Nungas, big, clean, and powerful. Expert territory for sure.
The following week looks good, with solid surf most days. Monday the 14th has some decent 7ft waves but the tides look a little trickier. From Tuesday the 15th through Thursday the 17th, we’ve got a steady run of SW groundswell in the 6ft to 7ft range, with periods holding in the sweet spot of 15-16 seconds. Winds remain light and cross-off, making for clean conditions day in and day out. Friday the 18th and Saturday the 19th see a slight drop in size, down to 4ft to 6ft, but there are still some fun clean waves to be had.
For the last part of the window, the swell is due to pick right back up. Sunday the 20th and into the following week looks promising, with the models showing a return of bigger SSW groundswell, hitting 7ft to 8ft by Tuesday the 23rd and into Wednesday the 24th. The periods are long, up to 17-18 seconds, and the energy readings are strong again, over 3000. This is another potential stand-out period, with the Wednesday the 23rd afternoon looking particularly special. Keep an eye on this one, it could be the best of the bunch. It’s further out, so we can’t be 100% sure, but the signs are good.
Overall, there isn’t a bad day on the horizon, but the true standouts are Wednesday the 9th and Sunday the 13th, with another promising pulse forming for the 23rd. The consistent SW swell and light offshore winds mean Nungas is going to be the place to be. Just remember, when it’s over 5ft, it’s not for the faint of heart, and at over 8ft, it’s experts only. There will be a few of you out there, and the crowds are likely at times, but for those who score it, it’ll be worth 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.
