The Lowdown

G’day, this is Rusty. Well, look, we’ve got one spot on the radar for the next 16 days, and it’s a ripper. Nungas is the only game in town, and it’s looking like a solid run of consistent swell, with clean conditions most of the time. The water’s sitting at 80°, which is pretty much bang on average for this time of year, so no surprises there.

The action kicks off this Friday the 4th of September. Friday morning and afternoon see a 5ft SW swell with a 14-second period. The wind is a cross-off from the SE, keeping things clean. The combined energy is moderate at 829, which is a decent start. The next few days build nicely. Saturday the 5th is a standout, with the swell bumping up to 6ft in the morning and 6ft in the afternoon, with the period stretching to 16 seconds in the arvo. The energy jumps to 1689, and the wind is still cross-off and clean. This is a solid day for an experienced surfer, but it’s not too intimidating for a keen intermediate.

Now, Sunday the 6th sees the swell hit 7ft in the morning, with a 14-second period, and by the afternoon, it’s 7ft at 17 seconds, with a light cross-shore wind. The energy is cranking at 2570. This is getting into that zone where it’s more for the experienced crew. Monday the 7th is another cracker, with 7ft, 14-second swell, and clean cross-off winds. The energy is 1770. Tuesday the 8th is a bit of a mix, with 6ft in the morning and 5ft in the afternoon, but that afternoon period is a massive 18 seconds, giving it a very long-period groundswell feel. The energy is up at 2934. This kind of long-period swell at a reef and point break like Nungas is where it really shines, offering up proper, well-shaped waves, but you’ll want to be patient between sets.

The real standout of the whole outlook is Wednesday the 9th of September. We’re looking at a 8ft SSW swell with a 16-second period in the morning. The combined energy is a massive 3504, which is strong. The wind is still cross-off and clean. This is big, powerful, and very clean. It’s definitely only for experts at this size. The afternoon gets a little cross-chop as the wind swings more southerly, but the morning session is the pick of the whole 16 days.

The swell dips a bit mid-week, with Thursday the 10th at 7ft, but it’s still clean. The pattern holds through the weekend and into the following week. The second week sees a lot of consistent 6ft to 8ft SW swell, with several days hitting over 7ft, and the wind stays nicely cross-off from the SE or SSE. The period is generally 14-16 seconds, which is great. Saturday the 19th of September, towards the very end of the forecast, sees another big pulse of 7ft SSW swell with a 17-second period and a light breeze, so keep an eye on that one, but it’s a long way out, so treat it as promising but not locked in.

Overall, this is a fantastic run for Nungas. The consistency is there, the swell direction is dead on from the optimum SW, and the winds are mostly clean. Crowds are possible, as it’s a fairly consistent spot, but with this much swell, there’ll be plenty of waves to go around. The only real caveat is that when the swell gets over 8ft, like on the 9th, it’s a heavy day that only the experienced should tackle.

Stay safe out there, and enjoy the run.

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.
