The Lowdown
Alright crew, Rusty here. Let’s break down Nungas over the next couple of weeks. This is a reef and point break that’s fairly consistent, and it loves a SW swell. We’ve got a solid run of SSW groundswell coming.
The water is sitting at 80°, which is pretty normal for this time of year, so no worries there.
The first few days are a bit of a slow start. Sunday the 26th and Monday the 27th have tiny waves around 2ft to 3ft, with a cross-off wind and clean conditions. The energy is weak (325) on Sunday, so it’s barely a ripple. Not worth suiting up for.
Tuesday the 28th is where we start to see something. Swell bumps to 3ft from the SSW with a 16-second period, and the energy is 496. That’s moderate, and the waves are clean with a gentle breeze. Still small, but the quality is there. Wednesday the 29th pushes to 4ft, and by Thursday afternoon the 30th, we’ve got 4ft with 15-second period and 1156 energy. That’s strong, and the surf is lining up.
The window to watch opens Friday the 31st. Swell is 4ft from the SSW, but the period stretches to 17 seconds, and the energy is 1328. The wind is light and cross-off. That’s a proper groundswell, and Nungas being a point and reef means it’s going to handle that long period like a dream. Saturday the 1st of August is the best of the first week: 5ft to 5ft, SSW then SW, 16-second period, light breeze, and 1613 energy. The surf is clean and excellent for experienced surfers. This is the one to mark on the calendar.
Sunday the 2nd keeps the stoke going with 6ft to 7ft SW swell, 17-second period, and 2611 energy. That’s getting solid, and it’s still clean. Monday the 3rd is similar, with 7ft SSW swell. Anything over 8ft is for experts only, so we’re still in the sweet spot. This whole run from Friday the 31st through Monday the 3rd is firing.
The second week stays active but the wind picks up. From Tuesday the 4th through Thursday the 6th, we’ve got 5ft to 6ft SSW swell, but the wind turns into a moderate cross-off. The energy is still high (1555 to 1750), but the surface will be a bit choppier. The surf is still good, but not as clean. Friday the 7th and Saturday the 8th see the same thing: big swell (6ft to 6ft) but moderate wind, so the quality dips.
Then we get a monster Sunday the 9th of August: 10ft SSW swell with 17-second period and 4328 energy. That’s huge. Expert-only territory. The swell is massive, the period is long, and the energy is off the hook. The wind is a gentle breeze, so it’s clean, but only for the brave. Monday the 10th is still heavy at 7ft SW, with 3005 energy.
The absolute best on offer is the stretch from Friday the 31st of July to Monday the 3rd of August. Good sized swell, long period, light winds, and the point break will handle it perfect. The Sunday the 9th spike is a beast, but it’s only for the experienced crew.
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.
