The Lowdown
Alright folks, Rusty here. Let’s get into it.
We’ve got a solid run of swell lining up for Nungas, a reef and point set-up that’s fairly consistent and handles a good S/SW push. The water is sitting at 79.3°, which is pretty much bang on average for this time of year, so no surprises there.
The real standout kicks off on Sunday the 23rd of August. We’re looking at a 6.9ft SSW groundswell with a 15-second period – that’s proper long-period energy, and it’s got some serious grunt behind it, with a combined energy of 2260 (moderate to strong). The wind is a gentle cross-off from the SE, which will keep the surface clean. This is excellent surf for experienced surfers; it’s a bit much for beginners at this size. That same pulse holds through Monday, still clean and solid.
Then we get a bit of a breather on Tuesday the 25th, with the swell dropping a touch, but the afternoon picks up again to 5.6ft. The real magic, though, is looking at Friday the 28th of August. That morning we’ve got a 9.8ft SW swell, 17-second period, and a combined energy of 4800 – that’s strong to very strong wave energy. The wind is light cross-off from the SSE. This is expert territory, no doubt. The waves will have serious power, and with that long period, Nungas as a reef and point will handle it beautifully, offering up some proper lines. The afternoon wind shifts to a light cross, so the morning is the pick.
The following week continues to deliver. Monday the 1st of September brings another 6.9ft SW swell, with the energy ramping back up. The wind stays light and cross-off, keeping it clean. This is a long stretch of quality, consistent surf, and the first week is the most reliable bet.
For the best of the best, I’d be circling Friday the 28th of August for the biggest, most powerful swell, and also Monday the 1st of September for a more manageable but still excellent session. Crowds are possible at Nungas, so get there early.

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.
