The Lowdown
Right, g'day, Rusty here. Let's get stuck into the outlook for Nungas, which is a reef and point setup. There's a solid run of surf on the cards, but it's not a flat start. The first decent wave is this afternoon.
The water temp is sitting at 80° right now, which is about average for the time of year, so no wild surprises on that front.
The pattern kicks off this Saturday afternoon (29th August) with a clean 7ft SSW swell, 15-second period, and a cross-off SE breeze. The combined energy is strong at 1750. This is proper groundswell, and while it's a beginner-friendly setup, that 7ft on a long period is pushing into experienced territory. It's a solid start.
Sunday (30th) sees a drop in size to 5ft SW swell, still clean with light SE winds, morning is best. Energy is still moderate at 873. Good, surfable waves.
Monday (31st) is an interesting one. The morning brings a 4ft SW swell, but the period is a massive 19 seconds. That's very long-period groundswell. The combined energy is still high at 1474, but for a reef and point, that long period should wrap in nicely and offer some proper lines. The afternoon kicks up to 5ft. Clean cross-off winds all day.
Now, the standout period. Tuesday (1st September) through to Thursday (3rd September) looks fantastic. Tuesday sees clean 7ft to 7ft SW swell (18-second period) with strong energy reaching 2974. Wednesday holds 7ft and Thursday drops to 6ft, all with clean cross-off winds. This is a run of quality, powerful surf for experienced surfers.
Friday 4th and Saturday 5th September it backs off a touch to 5ft and 5ft, still clean. Good for a cruise.
Sunday (6th September) morning is a highlight. Clean 6ft SSW swell, 14-second period, energy at 1618. The wind is cross-off and the conditions are clean. This is a ripper morning.
Monday (7th September) morning is another cracker: 7ft SSW swell, 14-second period, clean as a whistle. Energy at 1604. Excellent.
After a bit of a breather on Tuesday (8th) with a morning knee-high 5ft, the real fireworks start on Wednesday (9th September) . That morning we've got a 8ft SSW swell, 17-second period, and the combined energy is pumping at 3122. The wind is cross-off and clean. This is big, powerful, and long-period. For the reef and point at Nungas, this is going to be a serious session for experienced surfers only. The afternoon holds the same size.
Thursday (10th) is still solid at 7ft, but the wind picks up a touch.
Then, the absolute best of the bunch is Friday (11th September) . The morning delivers a 7ft SW swell with a 20-second period and combined energy of 4813. That's massive, powerful energy. The wind is a clean cross-off. This is a very long-period groundswell that will be cranking. The afternoon pushes to 8ft, but the wind turns cross-shore, creating a bit of chop. The morning is the magic window.
Saturday (12th) morning is still pumping at 8ft SW swell, 17-second period, energy at 3274, and clean cross-off winds. Another big session.
The run finally winds down through Sunday (13th September) with a solid 7ft to 6ft, clean again.
The standouts are clear: Tuesday 1st September through Thursday 3rd September for a sustained run of quality, and Wednesday 9th September and Friday 11th September mornings for the pure power and size. That Friday morning slot is the king of the 16-day window.
No crowds mentioned, so it might be a quiet one out there.
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.
