The Lowdown

G’day, Rusty here, and I’ve been staring at the charts for Nungas, and the outlook is a solid run of surf that’s going to build into a classic stretch of south-west groundswell. This is a reef and point setup, fairly consistent, and it’s got beginner-friendly potential, but we’re looking at a window where the size ramps up and demands a bit more respect. The water temp is sitting at 26.2°, which is about normal for this time of year, so no surprises there.

The surf kicks off on Tuesday, August 4th, in the afternoon. We’ve got a clean 1.6m swell from the SW with a period of 14 seconds, and the wind is a light cross-off at 10 km/h from the SE. The combined energy is moderate at 1002, and the conditions are clean. It’s a gentle start, a nice little intro, but the real action is building.

From Wednesday, August 5th, the swell starts to find its groove. The afternoon sees the swell hitting 1.6m from the SW, but the period bumps up to 15 seconds, and the energy jumps to 1359. The wind is still a light cross-off from the SSE at 10 km/h, making for clean faces. This is a long-period groundswell, and at a reef and point, it’s going to line up nicely. Thursday, August 6th, is where you need to pay attention. The morning swell is 2.0m from the SSW with a period of 18 seconds, and the energy is strong at 2462. The wind is a gentle cross-off at 15 km/h from the ESE, keeping it clean. This is a big, long-period swell, and the point should handle it beautifully, but it’s getting into expert territory at 2.0m. The afternoon pushes it further to 2.2m from the SSW with a 17-second period and 2731 energy, still clean with a light cross-off.

Friday, August 7th, is the standout. The morning swell is 2.2m from the SSW with a 16-second period, and the energy is 2711. The wind is a gentle cross-off from the ESE at 15 km/h, and it’s clean. But the afternoon is the real deal: 2.5m from the SSW with a 16-second period, and the energy is a massive 3217. The wind is a gentle cross-off from the SSE. This is big, powerful, and long-period. For a reef and point, it’s going to be a memorable session, but this is solid expert-only territory at 2.5m. Crowds are possible at Nungas, so get there early.

Saturday, August 8th, holds onto that size. The morning swell is 2.5m from the SSW, 16-second period, and 3062 energy. The wind is a light cross-off from the SE at 10 km/h, so it’s glassy. The afternoon drops a touch to 2.4m but still a 16-second period, and 2939 energy. It’s a touch cloudier, but still clean. The run continues through Sunday, August 9th, with a 2.3m morning swell and 2.2m in the afternoon, both from the SSW with a 16-second

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.
