The Lowdown
Alright, Rusty here, let's have a look at what's on the cards.
We’ve got a solid run of swell on the way for Nungas, a reef and point setup. It’s a fairly consistent spot that’s fairly exposed to the swell, so it’s going to be working for a good stretch here. The water temp is sitting right about where it should be for this time of year, so nothing unusual there.
The action kicks off on Saturday the 5th. The afternoon swell is already up to 6ft from the SSW with a long period of 16 seconds, so there’s proper groundswell energy in the water (1677). The wind is a cross-shore from the S though, so it’s a bit messy with some chop. It’s rideable, but honestly, wait for the cleaner stuff.
Sunday the 6th morning is where it starts to get interesting. The swell holds at 7ft from the SSW, period 14 seconds, and the wind shifts to a light cross-offshore from the SSE. That’s clean. The afternoon sees the swell bump to 7ft and the period jumps to 17 seconds, but the wind goes cross again, so the morning is the call.
Monday the 7th is a beauty. Both sessions are clean with light cross-off winds and consistent 7ft to 7ft swell from the SSW (period 14 seconds). The energy is moderate (1628-1770). This is a great window for experienced surfers on a longer board, that point will handle this long period well.
The standouts start rolling in from Tuesday the 8th. The morning has 6ft, 13 seconds from the SSW under light cross-off winds, and the energy is building (2288). But the real highlight is Tuesday afternoon: 5ft from the SSW with a massive 18-second period and a combined energy of 3094. That’s a lot of grunt for a 5ft wave. It’s clean and gorgeous. This is the session to circle.
Then Wednesday the 9th brings the biggest swell of the run. Morning sees 8ft from the SSW, period 16 seconds, and the energy is pumping (3504). The wind is a light cross-off, so conditions are clean. This is a solid, powerful swell – over 8ft, so this is experts only out there, but the reef and point will handle it beautifully. The afternoon is still a solid 8ft with similar energy.
The quality holds through the rest of the week and into the second. Thursday the 10th, Friday the 11th, and Saturday the 12th all offer clean, cross-off winds with swell in the 5ft to 7ft range from the SW/SSW. The periods are consistently 14 to 16 seconds, keeping the energy up. The 11th has a risk of t-storms, but the wind is still good.
Into the second week, things stay solid. Sunday the 13th has a 5ft to 6ft swell with a 19-second period in the morning – that’s a very long groundswell, perfect for the point. Energy is strong (2382). The 14th, 15th, 16th, 17th, 18th, 19th, and 20th all keep pumping out clean, 5ft to 7ft swell from the SW with light offshore or cross-off winds. The longest gap in quality is maybe a session or two where the wind shifts, but nothing that kills the run.
For the best on offer, I’m calling Tuesday afternoon, September 8th as the standout. That 5ft wave with an 18-second period and 3094 energy under light cross-off winds is a recipe for long, clean walls with easy paddling. The second standout is Wednesday morning, September 9th, for the biggest, most powerful swell of the window at 8ft, still clean. Crowds are possible at Nungas, so you’ll want to be early.
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.
