The Lowdown

Alright, mates, Rusty here. Let’s get into it. We’ve got a solid run of surf ahead for Nungas, and the opening stretch is looking seriously good. Right out of the gate on Tuesday the 4th, we’re seeing clean 5ft of southwest swell rolling in with a 14-second period. The water’s sitting at a comfortable 79°, which is pretty much normal for this time of year. Light cross-offshore winds keep things clean, and it’s a good, honest start. The wave energy is already pumping at 1043, so there’s plenty of push behind those sets.

The surf holds steady through Wednesday the 5th, with the swell building slightly and the period stretching out to 15 seconds. By the afternoon, the energy jumps up to 1368 and conditions stay crisp. You’re getting those long, lined-up waves that Nungas is known for, all with that clean, cross-off breeze. This is definitely a standout window for the week—very user-friendly too, so if you've got mates just getting into it, this is the time.

Thursday the 6th brings a noticeable step up in size. Morning bumps to 7ft, and by the afternoon we’re looking at 7ft with a 17-second period. The energy gets serious, hitting 2731, so there’s a lot of water moving. This is still clean, but the size is starting to creep into more experienced territory. We’re edging past that beginner comfort zone, so keep that in mind. The breeze stays light and offshore, which is a huge plus for the wave faces.

The pulse continues into Friday the 7th and Saturday the 8th. We’re in the 7ft to 8ft range now, with a strong, consistent southwest groundswell. Periods are hanging around 16 seconds, and the energy is charging— hitting 3549 on Friday afternoon. This is proper surf. The quality is excellent, and that light wind is making it look like a postcard. It’s a step up in power, so it’s time for your bigger board and your forward commitment. The point and reef setup here will handle this swell beautifully, giving you those grinding, open faces.

Sunday the 9th and Monday the 10th see a slight dip in size back to around 7ft, but the quality doesn't drop. In fact, Monday afternoon looks like another standout moment. The swell jumps back up to 8ft and the period extends to a very long 18 seconds. The energy meter explodes to 3844. This is when you get those long, clean, freight-train sets that just march down the point. It will be big, powerful, and a proper session for anyone who knows what they’re doing.

Tuesday the 11th might just be the pick of the whole forecast. You’ve got 8ft of swell, a solid 17-second period, and the energy reading is massive at 4427. The wind is light and cross-offshore, the skies are clear. It doesn’t get much better than this. This is the one to circle on the calendar. For the weekend warriors, expect a crowd potentially, but for everyone else, this is as good as it gets.

After that peak, things settle down a touch from Wednesday the 12th through Friday the 14th. We’ve got decent 5ft to 6ft of swell still coming through, but the energy backs off into the 1500–1800 range. It’s still very good surf, clean and rideable, but it’s not the thumping energy we saw mid-week. The period drops a little too, so the waves will be a bit more relaxed.

We get another interesting pulse around Saturday the 15th into Sunday the 16th. The swell size holds around 5ft to 7ft, but there’s a bit of a cross-off wind thing happening. It’s still surfable, but the winds get a touch stronger and the quality dips slightly to just “good.” The energy builds again on Sunday afternoon, with a new 18-second groundswell showing up. This looks promising for the following week, a sign that the ocean isn’t done with us yet.

And that leads us into the real winner for the second week. Monday the 17th afternoon sees the energy peak again, with a 8ft swell and a 17-second period, driving the energy up to 4618. That’s another huge reading. It’s cleaner again, too, with light winds and excellent surf conditions. Tuesday the 18th keeps the run going with similar size and quality, so if you can plan around this, you’ll be rewarded with some serious, long-period groundswell action. The week after is still a bit far out, so treat it as promising but not locked in.

For the whole run, Nungas (Nungas) is the only real option, but it’s a belter. A reef and point setup that loves a southwest groundswell, and this forecast is just feeding it. The consistency is fairly good, and the rare occasions it’s not working... well, this isn’t one of them. Just be aware that when the swell is over 7ft, it’s time for the more experienced crew. Anything in the 8ft range with that period is strictly for the experts. It’s not going to be a beginner’s playground during that stretch.

Rusty, signing off.

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.
