The Lowdown
Alright, Rusty here. Let’s talk about what’s on the menu. We’ve got one solid option on the table: Nungas. This is a reef and point break setup, fairly consistent and it’s got a bit of a beginner-friendly side to it, but don’t get too comfortable because this is a week that demands respect.
The overall pattern is a long, sustained pulse of SSW groundswell, and it’s packing some serious energy. The water temp is sitting about average for the time of year, so no shock to the system there, but don’t expect a warm bath.
We start on Saturday the 8th of August. Saturday morning at Nungas, the swell is 8 ft from the SSW, with a long 16-second period. That’s a groundswell with very long-period energy, and it’s directed here with combined energy of 3062 – that’s strong and there’s a lot of power in the water. The wind is a light breeze from the SE, cross-off, and the description says clean. This is serious, excellent surf for experienced surfers only. Anything over 8 ft is expert territory.
The standout of the whole outlook? Monday the 10th of August afternoon. The swell hits 8 ft from the SSW with an 18-second period – that’s a very long period groundswell – and combined energy of 4129. Wind is light breeze from the SSE, cross-off, clean. That’s a five-star session for the experienced crew. Tuesday the 11th morning is also a huge contender: 10 ft SSW, 17-second period, combined energy of 4394, clean with a gentle breeze cross-off. That’s some of the best, most powerful, and cleanest surf you’ll see all outlook. Over 8 ft, so experts only.
Come Thursday the 13th afternoon, we’re still seeing excellent conditions: 8 ft SSW, 16-second period, combined energy of 3470, light breeze, cross-off, clean. The wave quality holds.
There’s a bit of a lull around the 17th and 18th, where the swell dips a little and the winds get a bit stronger, but it’s still surfable for the confident crew. Then the kit really fires back up. On Wednesday the 19th of August morning, the swell jumps back to 10 ft from the SSW, 18-second period, combined energy of 5351 – that’s a very strong pulse. Clean with a gentle breeze. The forecast shows marginal conditions for the morning, but by Thursday the 20th afternoon, it’s back to excellent: 10 ft SW, 17-second period, combined energy of 4344, gentle breeze, clean. That’s another potential standout for the experienced.
Heading into the final weekend, Friday the 21st afternoon looks solid: 8 ft SW, 16-second period, clean. And Saturday the 22nd afternoon has 7 ft SW, also clean. The consistency holds right through.
A big caveat: because this is a long-period groundswell (think 15-18 seconds), the sets will be powerful and spaced out. At a point and reef break like Nungas, that’s a beautiful thing – it grooms the waves and makes paddling out easier between sets. But at a beach break, that long period can make the waves break too straight. Here, the reef and point setup is ideal. Also, keep an eye on the crowds: it says “sometimes” crowded, so you can expect other crew out there during these peak windows.
Bottom line: the real standouts are Monday the 10th afternoon, Tuesday the 11th morning, and Thursday the 20th afternoon. Those are your best bet for powerful, clean, excellent waves. This is solid expert territory for most of the outlook. Beginners, sit this one out.
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.
