Righto, let’s have a look at what’s on the cards. Nungas, a reef and point setup that’s fairly consistent and works best with a south-west swell, has a bit of a slow start. The first week is mostly building blocks rather than full-on barrels.
We kick off on Friday the 10th. The sea’s running at 5ft from the SSW, with a very long period of 15 seconds. The combined swell energy is strong at 1681. It’s clean, but the conditions are labelled marginal, so don’t expect perfection. Water temp is sitting at 82°, which is about a degree and a half warmer than normal for this time of year (anomaly 2°), so it feels a touch balmy. The wind is cross-off, so the face is clean but there’s a bit of bump.
Saturday the 11th is similar – 5ft SSW swell with a long period, moderate energy levels around 1124, but still just workable rather than epic.
Sunday the 12th morning is the first bright spot. A 4ft SW groundswell with 14 seconds, but the wind goes offshore from the ESE at 12 mph. That’s a big positive. The combined energy is lower at 480, but it’s clean and lined up. There’s not much size, but it’ll be fun for a beginner-friendly point break. The day after, Monday the 13th, sees the swell drop right off to 3ft, so it’s a lull.
Now, things start to build nicely from Tuesday the 14th. Swell pushes to 6ft from the SSW, period 18 seconds, and the energy jumps to 2006. The wind is cross-off, so it stays tidy. The sets get a little pushy by Wednesday the 15th – 7ft SSW, 17 seconds – that’s getting punchy. This is still clean but the energy is very strong at 2262.
The real standout in this first week is Thursday the 16th. The morning has 5ft SW groundswell at 15 seconds, with a light breeze from the SE at 6 mph – almost glassy. The forecast says “very good surf conditions”. The combination of that light cross-off and long-period groundswell should really suit the reef and point. Crowds are “sometimes”, so you might get a few out, but it’s early July.
For the second week, we’ve got a solid pulse arriving the following Monday, the 20th of July. The afternoon shows 7ft from the SSW, 16 seconds, and the combined energy is 2219. The comment is “excellent for experienced surfers”. That’s our best wave of the whole run. Tuesday the 21st is similar – 7ft SSW, period 15 seconds, with a light cross-off breeze. This is big, powerful groundswell. At 7ft, it’s getting into expert territory at Nungas, but the point and reef setup should handle it beautifully.
As we get to the end of the window, Friday the 24th of July has magic written all over it. The morning is glassy – 3 mph from the ESE, no wind at all. The swell is 4ft SW at 15 seconds, and the wave energy is moderate at 864. That’s a clean, long-period swell with zero chop. If you can wait that far out, that’s a golden session.
The very last day, Saturday the 25th, pumps up again: 6ft SW with 16 seconds, light cross-off breeze, 1806 energy, rated “excellent for experienced surfers”. A fine way to close out.
Overall, the best windows are the morning of Thursday the 16th for a mellow but high-quality day, and then the afternoon of Monday the 20th through Tuesday the 21st if you’ve got the skill for a solid-sized groundswell. And if you’ve got real patience, the glassy session on the 24th is a hidden gem.

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.
