The Lowdown
Hey, it’s Rusty. Let’s talk surf for the next couple of weeks.
Everything’s happening at Nungas, a reef and point break that’s fairly consistent. Water temp is normal for the season. The first real waves arrive on Friday, September 11th, with a SW groundswell at 7 ft, a very long period of 16 seconds, and a cross-off wind from the SE at 9 mph. The combined energy is strong (2195). It’s clean, but at that size, it’s for experienced surfers. The point and reef will handle the long period well, giving you nice lines. The afternoon drops to 7 ft with lighter wind.
Saturday the 12th and Sunday the 13th keep the quality. Saturday morning: 5 ft, 15-second period, clean. Sunday morning is the true standout: 6 ft, 18-second period, combined energy 2585 (strong), light winds – that’s a dream setup. Sunday afternoon gets bigger to 8 ft, but wind picks up to 12 mph, still clean but pushing expert-only.
The whole first week is filled with excellent conditions for experienced surfers, with swell between 5 ft and 7 ft, periods 14-16 seconds, and cross-off winds. Best days are Tuesday the 15th and Wednesday the 16th – clean and consistent.
We get a mellow patch around the 18th-19th, swell dropping to 5 ft, energy lower (around 1000), but still clean. Then a second pulse hits Sunday, September 20th: 7 ft to 8 ft, 16-17 second period, energy back up to 2531-2645 (strong). That’s another expert window with light winds. The 21st and 22nd stay solid but with shorter periods.
The 24th gets a cross-shore wind from the S, bringing some bumps. The 25th and 26th see the swell fade to 4 ft, energy down to 829 (weak), but light winds make it fine for beginners.
The two standouts: Sunday, September 13th (6 ft, 18 seconds, clean) and Sunday, September 20th (8 ft, 16 seconds, light winds). Both are expert-level on the bigger days. Nungas can get crowded sometimes, so plan accordingly.
Second week holds up, but confidence is a bit lower. The 21st and 22nd are still good, then the 23rd and 24th get wind-affected, but there’s a clean window on the 25th morning.
That’s the word. Catch you out there.

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.
