The Lowdown
G’day, I’m Rusty. Let’s get into it.
We’ve got a solid stretch of SW groundswell lining up for Nungas (reef and point). The water temp is sitting at 80°F, pretty much dead-on average for this time of year, so no surprises there. The first proper action kicks off Monday the 14th and honestly, it doesn’t really let up for the whole 16 days. The combined energy is moderate to strong throughout, and it’s almost all long-period SW groundswell, which is perfect for a setup like this—reef and point breaks handle that long-period juice beautifully, giving you proper shaped waves and decent gaps between sets to get back out.
Monday morning the 14th, we’re looking at a clean 7ft SW swell with a 16-second period, cross-off wind from the ESE at 12 mph. It’s a bit punchy at that size, better suited to experienced surfers. The combined energy is 1945 (moderate to strong) and the wave comment says marginal surf or questionable tide conditions, but the wind keeps it clean. Monday afternoon drops to 6ft, still 16-second period, wind lightens to 6 mph SE—still cross-off, and the energy is 1764. That afternoon session is where it’s at for the day.
Tuesday 15th holds similar: 6ft SW, 15-second period, SE wind 9 mph, energy 1534. Clean again. The whole week rolls on like this—morning sessions generally rating a solid “excellent” for experienced surfers, afternoons a touch more marginal but still clean. The swell sticks around 6ft to 7ft, with period dropping to 14 seconds mid-week, but still decent. Crowds are listed as “sometimes,” so you might get a few others out, but it’s not a circus.
The standout windows? Look at Sunday the 20th: morning sees 6ft SW swell, 17-second period, light SE wind at 6 mph, energy 1972. That’s a gorgeous long-period groundswell with glassy morning vibes. Monday the 21st is similar: 7ft SW, 15-second period, light SE wind, energy 1941. Both mornings are clean as a whistle.
But the real highlight—and I mean the one that gets you out of bed—is Sunday the 27th. The morning starts with 7ft SSW swell, 15-second period, ESE wind 9 mph, and the combined energy is 3280 (strong). The afternoon though? That’s the session. 6ft SSW swell, but the period jumps to 21 seconds—very long period groundswell—wind drops to 6 mph SE, energy hits 4786 (very strong). That’s a rare, powerful groundswell with clean conditions. Then Monday the 28th cranks up even bigger: 10ft SSW, 17-second period, energy 5349 (very strong). That’s expert territory—too big for beginners, but for the crew who know what they’re doing, that’s as good as it gets. Wind stays cross-off and light.
Late in the run, Tuesday the 29th still holds 7ft SSW with 16-second period and energy 2151. The whole two weeks are firing. No gaps, no dead periods—just consistent, clean, long-period SW groundswell. If you can only pick a couple, aim for the 27th afternoon and the 28th morning.
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.
