The Lowdown

Alright, this is Rusty. Let’s have a look at what’s shaping up.

We’ve got a solid run of surf on the cards here, and it’s all at Nungas. This is a reef and point set-up that likes a solid SW swell, and that’s exactly what’s coming. The water temp is sitting about average for this time of year, nothing out of the ordinary there.

Things kick off on Wednesday the 26th of August. We’re looking at a clean 6ft SW groundswell with a period of 14 seconds. The wind is a light cross-off, so the face should be pretty tidy. The combined energy is pumping at 1212 (moderate to strong), and it’s a good, surfable size for most. The afternoon holds similar but swings a touch more SSW.

Thursday the 27th drops a fraction in height to 4ft, but the period stretches out to a lovely 16 seconds, making it a proper groundswell. The morning is clean, but the afternoon is where it gets interesting – the energy jumps to 1467 and it’s calling for excellent conditions for experienced surfers. The smaller size means it won’t be as intimidating.

Now, Friday the 28th is the standout. We’ve got 8ft of SW swell at 17 seconds. That’s a big, powerful groundswell with very high energy (4343 in the morning). This is expert territory. The winds are clean cross-off all day. This is the one to circle on the calendar – it’s going to be pumping, but only for those who know what they’re doing. Expect some crew out there because it’s Nungas, and it’s fairly consistent.

Saturday the 29th is still excellent, with 7ft on the same long-period SW groundswell. Energy is still very strong at 2249. The wind is a touch lighter in the morning, a light breeze, making it glassy. Still a big, powerful wave. Sunday the 30th sees it back off to a more manageable 5ft, but the period drops to 13 seconds. Still clean and fun.

Moving into the new week, Monday the 31st has a weird mix. The morning is a smaller 4ft but with a very long 19-second period, which can be a bit tricky on a point break – it can straighten out. The afternoon bumps up to 5ft with 18 seconds, and the energy is solid at 1728.

The first week of September keeps the swell alive. Tuesday the 1st and Wednesday the 2nd have solid 7ft to 7ft SW swells, but the wind gets a bit more cross than cross-off on those afternoons, introducing a slight chop. Still plenty of energy there.

The second week drops off a bit. From Thursday the 3rd of September into the weekend, the swell sits around 5ft to 6ft, but the wind isn't as kind – more cross and cross-off, with some light chop. The energy dips into the moderate range (907 to 1505). Still surfable, but not the same quality as that first week.

Sunday the 6th and Monday the 7th see a slight pulse of 6ft to 6ft SSW swell, with light offshore winds. The energy climbs back up, making for clean, fun waves for experienced surfers.

The very end of the outlook, around the 9th and 10th of September, shows another strong pulse. Wednesday the 9th has a 7ft SW swell with 17 seconds, but the wind is a moderate breeze. The afternoon, however, has a 7ft SW swell with a nice offshore wind (ESE at 16 mph), which should clean it up nicely. Thursday the 10th has a 8ft SW swell at 17 seconds with very high energy (3570), but again with a moderate cross-off breeze.

Overall, the best on offer is undeniably Friday the 28th of August. The combination of size, long period, and clean wind makes it a no-brainer for anyone who can handle it. The Saturday after that is also a fantastic option.

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.
