The Lowdown
Alright, Rusty here. Let’s get into this one. We’re looking at Nungas, a reef and point break that’s fairly consistent and exposed to a SW swell. Water temp is sitting at 79°F, and the anomaly is only -0.2°F, so that’s bang on average for this time of year—nothing to worry about there.
For the first few days, Wednesday the 26th and Thursday the 27th are looking decent but not the main event. Wednesday morning serves up a clean 6ft SSW swell with a long 14-second period, cross-off winds from the ESE at 9 mph, and moderate wave energy (1126). It’s good, surfable, and beginner-friendly. Thursday afternoon nudges up to a slightly better score with a 4ft SW swell, 15-second period, and a bigger energy reading (1528), still clean and glassy.
Now, here’s where it gets exciting. Friday the 28th is the standout of the whole outlook. Morning brings a solid 8ft SW groundswell with a 17-second period, cross-off light breeze (6 mph), and strong wave energy (4343). That’s the kind of power that gets the heart pumping. This is expert territory at that size, especially with the long-period swell—it’ll be lining up beautifully on the point, but the reef might get a bit heaving. Saturday the 29th is still pumping with 7ft SW swell in the morning and energy dropping to 2331, but still very clean. Excellent stuff for experienced surfers.
The first week stays consistently good. Sunday the 30th drops to a smaller 5ft but remains clean. Monday the 31st has a touch of that long-period magic again (19 seconds) with a 5ft SSW swell in the afternoon, and the energy is solid at 1731. Tuesday September 1st sees another pulse of 7ft SW swell with 18-second period and energy hitting 2800—another top-tier session for those who can handle it.
The second week is still promising but less certain. Wednesday September 2nd holds at 7ft SW with a 17-second period, and Thursday the 3rd is a bit smaller at 6ft. Both are clean and manageable for competent surfers. By Friday the 4th, we’re down to 4ft, but still clean and fun. Saturday the 5th is the weakest day—4ft and the energy is barely moderate (510–580)—but the wind is light. Worth a paddle if you’re keen.
Then, a pulse arrives again on Sunday September 6th: 7ft SSW swell with 16-second period, light breeze, and energy near 1900. That’s another good day for the experienced crew. Monday the 7th holds similar 6ft SSW, and Tuesday the 8th brings a very long 21-second period swell (4ft) with 1922 energy—this will be a beautiful, clean, punchy wave on the point, but that long period means it might be a bit too straight at the beach. Wednesday September 9th sees another spike to 8ft SSW with 17-second period and massive energy (3473)—that’s a proper swell for experts only, but a dream for those who know the reef. Thursday the 10th winds down with 7ft SW, still clean.
Best on offer: Friday August 28th morning (8ft SW, 17s, 4343 energy, light offshore) and Monday September 9th morning (8ft SSW, 17s, 3473 energy, glassy conditions). Both are for the experienced only, but they’re the kind of days you circle on the calendar.
Crowds at Nungas can be a factor sometimes, so get in early on those standouts.

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.
