The Lowdown
Alright, Rusty here. Let’s just cut to the chase. The next couple of weeks at Nungas are looking like a proper run of clean, consistent swell. This is a reef and point setup, beginner-friendly when the swell is down, but it can get serious. The water temp is sitting at 80°, which is pretty much normal for this time of year, so no surprises there.
We kick off Monday the 7th with some solid SSW groundswell. The morning sees 7ft of swell coming from the SSW, with a 14-second period, and the combined energy is moderate to strong (2009). The wind is a gentle SSE breeze, cross-off, keeping the surface clean. This is excellent, but at 7ft, it's starting to push into the territory for experienced surfers only. The afternoon holds the same quality, just a touch smaller at 6ft, but still clean.
Tuesday the 8th is a bit of a mixed bag. The morning swell is still 6ft from the SSW, but the period drops to 13 seconds, and the energy is still strong (2288). It’s still clean. The afternoon is where the real standout happens: the swell period jumps to 18 seconds, a long-period groundswell. The swell height is 5ft, but the energy is very strong (3094). For a point break like Nungas, this long period will create some of the best, most lined-up waves you’ll see. The wind is still cross-off and clean. This is the standout of the first week.
Wednesday the 9th is a big day. The morning we’ve got 8ft from the SSW, 16-second period, and the energy is pumping (3504). That’s a big, powerful swell. This is expert-only territory. The wind is still a gentle cross-off. The afternoon is just as solid at 8ft. If you’re not an expert, pick a smaller day.
Thursday the 10th and Friday the 11th continue the pattern of clean, 6ft to 7ft SSW swell, with periods in the 15-17 second range. The wind stays cross-off, mostly light to gentle. This is a long, drawn-out run of quality surf. The energy values are consistently in the 2000-2600 range, which is a solid moderate to strong push.
The weekend of the 13th and 14th holds strong, with 6ft to 7ft SSW swell, 16-18 second periods. The morning of the 13th has a light breeze, making it glassy. The afternoon of the 13th brings some rain showers, but the wind is still cross-off, so the surf will stay clean. Monday the 14th has a bit more wind, a moderate SSE breeze at 12 mph, but it’s still cross-off, so it’s still surfable.
The middle of the week, from the 16th to the 18th, the swell backs down a bit. We’re looking at 4ft to 6ft from the SW, with periods dropping to 14 seconds. The energy drops too, into the 1200-1500 range. The 18th in particular has smaller, 4ft waves, but the light breeze and 16-17 second period will make for some clean, fun, smaller waves for the beginners.
Then, hold on to your board. Saturday the 19th through Monday the 21st sees a return of strong, 7ft to 8ft SW swell, with 15-16 second periods. The energy is back up into the 2500-3500 range. The wind is light to gentle and cross-off. This is another excellent run.
But the absolute standout of the entire 16-day window is Tuesday the 22nd. The morning swell is 8ft from the SSW, but the period is a massive 21 seconds. That is a very long-period groundswell. The energy is through the roof at 6446. Then the afternoon hits with 12ft of swell, 20-second period, and an incredible combined energy of 9161. This is a very strong, very powerful, exceptional swell. The wind is a gentle S cross-off, keeping it clean. This is for experts only, and it’s the one you want to circle on the calendar. It’s over a week away, so keep an eye on it, but the long-range forecast is looking very promising for this one.

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.
