The Lowdown

Alright folks, Rusty here. Let's have a look at what Nungas is cooking up for us over the next couple of weeks.

The water temp is sitting at 79°, which is bang on average for this time of year, so no surprises there. The first few days are a bit of a slow burn, nothing to write home about just yet. We’ve got clean conditions, but the swell and energy are still finding their feet.

We start on Tuesday the 25th with messy, marginal waves around 5ft to 6ft. The wind is cross-off, but the energy is weak in the morning (1121) and the swell direction is a bit mixed, coming from the SSW with a short period on the morning session. It’s not really offering much for a proper session. Wednesday the 26th is similar, still clean but the swell is short-period and the energy (1209) is nothing special.

Now, Thursday the 27th afternoon is where things start to get interesting. The swell drops to 4ft, but the period jumps to 15 seconds and the energy spikes to 1505. That’s a classic groundswell pulse. The wind is a light cross-off, so it’ll be clean. This is a good window for the more experienced crew – the long period means better shape but longer lulls between sets.

The absolute standout, no question, is Friday the 28th. Both morning and afternoon are firing. We’ve got a solid 8ft swell from the SW with a 16 to 17 second period. That’s a serious, powerful groundswell. The energy is huge – 4343 in the morning and 3808 in the arvo – and with light cross-off winds, it’s going to be clean and throwing. This is expert territory at this size, but for the brave, it’s the best day of the entire forecast. The swell direction is SW, which is hitting Nungas right in its optimum zone.

Saturday the 29th carries that energy forward, with 7ft dropping to 6ft, still a strong groundswell and still clean. Excellent conditions for experienced surfers again. Sunday the 30th backs off a little, but remains clean and rideable for the average punter.

Moving into the second week, we see September kick off with a solid pulse on Monday the 31st. The swell is 4ft to 5ft but with a very long 18 to 19 second period. That’s a deep ocean groundswell. The energy is good (1402 to 1744), and the wind is light cross-off. This will be a proper clean swell for the points and reefs. Tuesday the 1st of September shows a bigger 7ft swell from the SW, but the morning session is flagged as marginal due to tide, so pick your time. The afternoon is clean and firing again.

The run from the 3rd to the 9th of September is a consistent stretch of clean, rideable surf. Swell heights sit between 4ft and 7ft, all coming from the SW or SSW with decent period. The wind stays light to gentle cross-off for most of it. There are a couple of mornings (2nd and 8th of September) with more cross-chop, but nothing that ruins it. The real highlight of the back half is the afternoon of the 9th of September – a 6ft swell from the SSW with a long 18 second period and energy of 2723. It’s a big, clean groundswell pulse to finish the window.

So, to wrap it up: Friday the 28th of August is the hands-down winner – epic size, long period, clean wind, and a big energy reading. If you’re an experienced surfer, that’s your day. For the rest of the run, Nungas is in a solid, consistent groove with plenty of clean sessions for all levels, especially from Thursday the 27th onwards.

Stay wet,
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.
