The Lowdown
Alright folks, Rusty here. We’ve got a solid run of surf coming up at Nungas, a reef and point set-up that’s a great spot for a beginner. The water’s sitting at 80°, which is pretty much normal for the time of year, so no surprises there.
The overall pattern is a long stretch of consistent, clean waves from Sunday the 6th onwards. The combined energy of the swells is strong to very strong, with values like 1,626 (moderate) all the way up to 4,126 (very strong). We’re looking at a south-southwest swell direction, which is right in the sweet spot for this break. The period on the swells is mostly 14-17 seconds, which is long-period groundswell. That means better shaped waves, more energy, and longer gaps between sets – makes paddling out a bit easier. Being a reef and point, it’s well-suited to handle that long period stuff.
Now, the standout period is the weekend of the 19th and 20th of September. The swell pumps up to 10 ft early Saturday morning, with a period of 16 seconds and a solid 4,126 combined energy. That’s big, powerful, and only for experienced surfers – over 8 ft puts it firmly in the expert zone. The wind is light and cross-offshore, keeping things glassy. Then Sunday the 20th keeps that energy rolling with another 10 ft swell and light, cross-offshore winds. That’s the best of the bunch.
The rest of the period is excellent. From the 6th right through, you’re looking at clean waves with swell heights mostly between 5 ft and 8 ft. The wind stays cross-offshore nearly the whole time, which is a massive positive for clean faces. The 17th is a bit of a hiccup, with a gentle cross-shore breeze that might bring a little chop, but it’s still surfable. Crowds are a possibility here, as it’s a spot that gets busy sometimes.
The 6th of September kicks it off with a 6 ft, 14-second swell and clean conditions. Good for a beginner-friendly wave. The 7th, 8th, and 9th keep the consistency, with the Wednesday morning of the 9th hitting 8 ft. The 16th of September is a solid call, with 6 ft swells and clean conditions. The 18th has a nice 7 ft to 7 ft swell, but the afternoon turns a bit cross-shore. The 21st of September winds things down with a 7 ft swell in the morning.
If you’re an experienced surfer, don’t miss that weekend of the 19th and 20th. For everyone else, the whole run is a treat.
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.
