The Lowdown
Alright folks, Rusty here. Let’s have a look at what’s cookin’.
We’ve got a solid run of surf ahead at Nungas. This reef and point setup starts pumping from Monday afternoon and barely lets up for over two weeks. The water’s sitting at 80°, which is bang on average for this time of year, so no surprises there.
The first real standout kicks off Monday afternoon, September 7th. We’re looking at a 7ft SSW groundswell, with a period of 14 seconds. That’s proper energy—long lines, plenty of push, and the combined energy reading (1792) tells you there’s moderate to strong pulse in the water. The wind is a gentle cross-off from the SSE, keeping the face clean. That’s a prime window for experienced surfers.
Tuesday, September 8th, keeps the quality high. Morning sees a 6ft SSW swell, but the afternoon steps it up: 5ft SSW swell with an 18-second period. That’s a super long period, meaning those sets will be fat, powerful, and better for the point than the reef section. The energy jumps to 3154, so there’s plenty of grunt.
Wednesday, September 9th, is another cracker. Morning has an 8ft SSW groundswell at 16 seconds—strong and clean. The combined energy hits 3504. That’s heading toward expert territory but still manageable if you know your spot. The wind stays cross-off and gentle.
Thursday, September 10th, offers a 6ft SSW swell in the morning, but the afternoon drops to a “marginal” tag due to tide. Still, the swells are solid.
Now, the standout of the whole run has to be Sunday, September 13th. The afternoon delivers a 8ft SW groundswell with an 18-second period, and the combined energy screams 4049. That’s strong wave energy, and with a light cross-off breeze, it’s about as good as it gets for experienced surfers.
If you’ve got the skills, also circle Sunday, September 20th. That morning brings a 10ft SW groundswell at 17 seconds—big, deep, and powerful. Combined energy hits a massive 4614. This is expert-only territory. The wind is light and cross-off, so it’ll be clean, but that size and period will make it heavy. Best suited to the point.
Nungas is fairly consistent and fairly exposed to the SW swell, which matches the optimum direction. Crowds are a factor here—they’re listed as “sometimes,” so you can expect company on the best days, but the quality makes it worth it.
From around Tuesday, September 22nd, the swell drops off a touch, with 6ft to 6ft SW swells and shorter periods around 13 seconds. Still fun, but the energy fades (1147–1338), and the magic window has passed.
So overall, if you’re chasing clean, powerful groundswell with offshore-friendly winds, Nungas has a long, strong run. The best are September 13th afternoon and September 20th morning. Get 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.
