The Lowdown
G'day, Rusty here. We've got a solid run of surf on the cards at Nungas, a reef and point set-up that's fairly consistent and picks up a good SW swell. The water's sitting at 80°, which is spot on for this time of year, nothing unusual there.
The action kicks off Sunday afternoon, August 2nd, with a solid 7ft SSW groundswell, long period of 17 seconds, and a light ESE breeze holding it clean. The energy's pumping hard at 2127 (strong wave energy). This is proper stuff, but at this size and with that long period, it's best left to the experienced crew – the paddle out will be easier between sets, but the waves will be powerful.
We get a bit of a lull Monday morning, August 3rd, with the swell dropping to 6ft, but still a long 15-second period from the SSW. The wind is a gentle cross-offshore from the ESE, keeping things clean. The energy dips a bit to 1241 (moderate wave energy), but it's still a very good session. This trend holds through Monday afternoon and into Tuesday, August 4th, with the swell holding around 5ft and the same clean cross-off wind. The energy settles into the 1000s, which is still moderate.
Wednesday morning, August 5th, is similar, but Wednesday afternoon sees the swell bump back up to 5ft, with the period stretching to 15 seconds and the energy jumping to 1374 (moderate). The wind stays clean from the SE. The real standout then hits on Thursday, August 6th – the swell jumps to 7ft in the morning and 7ft in the afternoon, with a very long period from the SSW (18 seconds) and the energy surging into the 2000s (strong). The wind is a moderate cross-off from the ESE and SSE, keeping it clean. This is a big, powerful groundswell, and at Nungas, a reef and point, it'll handle that long period well. It's an expert-only zone at this size.
Friday, August 7th, is the pick of the lot. The swell builds to 8ft in the morning and 8ft in the afternoon, with a 17-second period from the SSW. The energy is blasting into the 3000s (very strong). The wind is a gentle cross-offshore, which is a dream. This is serious, powerful surf for experienced surfers only. Saturday, August 8th, holds that same 8ft SSW swell, with the energy still in the 3000s. The wind stays a gentle cross-off. This is a peak period of solid, consistent swell.
The swell slowly eases from Sunday, August 9th, through to Tuesday, August 11th, dropping from 7ft down to 6ft, but the period stays long and the energy remains strong, in the 2000s. The wind is light to gentle and cross-offshore, keeping it clean. This is excellent, high-quality surf.
Wednesday, August 12th, sees the swell drop to 6ft and the energy back to 1430 (moderate). The wind is a moderate cross-off from the SE, which is still clean. Thursday, August 13th, the swell jumps back to 7ft in the morning and 8ft in the afternoon, with a very long period of 18 seconds from the SSW. The energy rockets to 3955 (very strong). However, the wind picks up to a moderate 12 mph cross-off, which can make things a bit lumpy. It's still a big, powerful swell for experts. Friday, August 14th, holds that 8ft mark with a moderate cross-off breeze, energy in the 3000s. The weekend of August 15th and 16th sees the swell drop back to 7ft and then 6ft, with the period staying long. The wind is a gentle to moderate cross-off, keeping it clean. The best of the late period looks like Sunday afternoon, August 16th, with 6ft SSW swell, 17-second period, and clean conditions.
The big standouts are definitely Friday, August 7th, and Saturday, August 8th, with that 8ft, long-period SSW groundswell and clean, gentle cross-off winds. It's a powerful, consistent run for the experienced surfer.
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.
