The Lowdown

Alright folks, Rusty here. Let’s have a look at what’s on the menu for the next couple of weeks. We’ve got one spot on the radar, and it’s looking like a solid run of swell with some real standout sessions.

The overall pattern is a sustained pulse of SSW to SW groundswell, with a long period that’s going to give us some proper, powerful lines. The water temp is sitting about average for this time of year, so nothing too wild there. The first real action kicks off on Friday the 4th of September at Nungas, a reef and point break that’s a beginner-friendly setup but handles a decent swell well. The wind is forecast to be a light cross-offshore breeze, which is a major plus for keeping things clean.

We start with a clean 5 ft SW swell on Friday morning, with a long 14-second period. The combined energy is moderate at 833. The afternoon holds similar size and conditions. The weekend sees a build. Saturday morning the 5th gets a bump to 6 ft from the SSW, with the energy jumping to 1240. The wind remains cross-off, keeping it glassy. Saturday afternoon the swell bumps to 7 ft, but the wind shifts to a cross-shore, adding a little texture.

Sunday the 6th offers a solid 6 ft in the morning with cross-off wind, but the real standout for the first week looks like Monday the 7th of September. The morning sees a 7 ft SSW swell with a 14-second period, the energy is a strong 1770, and it’s clean. This is when it starts getting a bit punchy. The forecast says this is excellent for experienced surfers, and I’d agree. Anything over 7 ft here with that long period is going to have some push.

The swell continues to fluctuate through the middle of the week, with a peak on Wednesday the 9th hitting 8 ft. That’s getting into the "experts only" territory, and the wind is mostly cross-shore, so it’s not the cleanest pick. The energy is very strong at 3300 though – you’ll feel that.

Things really clean up again for the second week. Friday the 11th of September is a proper standout. Morning and afternoon both show a 7 ft SW swell, a 16-second period, and cross-off wind. The energy is over 2000. This is a premium session with clean, powerful lines. The following Saturday the 12th is also a beauty, with a slightly smaller 6 ft and lighter winds, making it very user-friendly.

The run of excellent, clean conditions continues pretty much non-stop from the 11th through to the end of the window. Monday the 14th and Tuesday the 15th both have 7 ft to 7 ft SW swell with cross-off wind and solid energy. Then Thursday the 17th of September looks like a real highlight: a 8 ft SSW swell, a very long 17-second period, feathering light winds, and energy at 2918. That is a proper groundswell pulse. Because it’s a reef and point break, it’s going to handle that long-period energy perfectly, giving you lined-up, grinding waves rather than the wonky closeouts you’d get at a beach break.

The crowds are listed as "sometimes" here, so you might have some company, but with this much swell on offer, there’ll be waves for everyone.

Bottom line: the first few days are good, but the real magic starts from the 11th onwards. If you can only pick one session, the 11th, 14th, or 17th of September are the absolute standouts for clean, powerful, offshore-condition surf. Get on it.

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.
