The Lowdown

Alright folks, Rusty here. Let's have a look at what Nungas has in store for us over the next couple of weeks.

Right off the bat, we’ve got a solid pulse of south-west swell coming in. Monday morning (20 July) kicks things off with a clean 5ft SW swell, but the wind is a cross-off from the SE. The water’s sitting at a warm 82°, which is a touch above the norm for this time of year. The combined energy is pumping at 1924 (moderate to strong), and with a 15-second period, this is proper groundswell. That long period means the waves will have plenty of shape and power, but at a reef and point like Nungas, it should line up nicely. The standout window is definitely Monday afternoon (20 July) – the swell bumps up to 7ft from the SW, period stretches to 17 seconds, and the energy jumps to 2442. That’s a serious amount of water moving. The wind stays cross-off, so it’ll be a bit textured, but for experienced surfers, this is the best of the whole run. This is the one to point your board at.

Tuesday (21 July) sees the swell drop a touch to 6ft in the morning, still with that long 15-second period, but the wind remains cross-off. The energy is down to 1420, and it’s looking marginal. By Tuesday afternoon, the swell has dropped further to 6ft, the period shortens to 14 seconds, and the energy is 1126. It’s still clean, but the quality is fading.

We then hit a long, flat spell. From Wednesday (22 July) right through to Tuesday morning (28 July), the swell gets smaller and smaller. Heights hover around 3ft to 4ft, but the energy drops into the low hundreds – 633, 614, 481 – it’s weak. The wind is a persistent cross-off, so the waves are clean but gutless. There’s a brief flicker of life on Saturday afternoon (25 July) with a 3ft SSW swell and a 15-second period, energy at 636, and the forecast says “expect good surf conditions,” but it’s still small. The crowd situation at Nungas can be a problem – it’s a spot that does get busy sometimes, so be prepared for company if you paddle out.

Things start to get interesting again on Wednesday, 29 July. The afternoon shows a 5ft SSW swell, 14-second period, and energy climbing to 944. The wind is a light SE cross-off, and the forecast says “expect very good surf conditions.” That’s a promising sign.

The real resurgence comes on Thursday, 30 July. Morning delivers a 3ft SSW swell, but the period is a massive 19 seconds – that’s a very long-period groundswell. The energy is 1448, and it’s excellent for experienced surfers. The wind is a light ESE cross-off. Then the afternoon gets even better: same 3ft, 19-second period, but the energy jumps to 1661, and there’s a risk of thunderstorms, but the wind drops to a light breeze from the SE, 10 km/h. That’s glassy conditions. This is a hidden gem of a day – very clean, long-period waves for the crew who know how to handle them. Friday, 31 July, is also excellent, with a 5ft SSW swell in the morning, 15-second period, and energy of 1768. The wind is light and cross-off. The afternoon is 5ft with a 17-second period and energy of 1883. Another cracker.

The first weekend of August (1st and 2nd) holds onto that 5ft to 5ft range, but the period drops to 16 seconds, and the wind is a moderate 20 km/h cross-off. The energy is still in the 1300 to 1400 range, so there’s plenty of push, but the wind will put a bit of texture on the face. It’s still worthwhile, just not as pristine as the Thursday and Friday before.

By Monday, 3 August, the swell fades again, dropping to 3ft in the morning, and the energy is down to 602. The afternoon picks up a little to 4ft, energy 668, and the forecast says “expect very good surf conditions,” but it’s a far cry from the big pulse.

Tuesday, 4 August, ends the outlook with a 5ft SSW swell in the morning, 16-second period, energy 991, and a clean cross-off. The afternoon is 4ft, 15 seconds, and energy 935, with another “very good” forecast. It’s a solid finish to the run.

The absolute standout is Monday afternoon, 20 July – that 7ft, 17-second groundswell with 2442 energy is the best wave of the period, but it’s for the experienced crew. For the cleanest, most user-friendly conditions, look at Thursday, 30 July, through Friday, 31 July – the light winds and long-period swell will produce some beautiful, lined-up waves at this reef and point.

Rusty out.

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.
