The Lowdown

Alright, let’s get into it.

We’ve got a solid run of surf ahead. The window starts with a bit of a slow burn, but it’s building into something real. The first day, Tuesday the 25th, is pretty average—some chest-high lines around 5ft but the energy is weak, and the conditions are just okay. There’s a morning session possible, but honestly, I’d hold off.

Wednesday the 26th looks a touch better. Still not huge, but the swell is a bit more organized at 6ft, and it’s clean with light winds. The energy is moderate. You’ll get some fun ones but nothing to write home about.

Thursday the 27th is where it starts to pick up. The morning is small at 3ft but clean. The afternoon is where you want to be—swell bumps to 4ft, but the period jumps to 15 seconds and the energy reads much better. It’s a proper groundswell, and the break starts to come alive. This is a good warm-up.

Now, Friday the 28th is the first real standout. The swell jumps to 8ft out of the SW, with a 17-second period. The energy is strong. This is a solid, powerful swell. The winds are light offshore, and it’s going to be clean and lined up. This is for the crew who know what they’re doing—8ft is beyond beginner territory. This is where Nungas shows its true reef and point potential.

Saturday the 29th is still pumping, with 7ft to 7ft surf, solid energy, and clean conditions all day. It’s not quite the peak of Friday, but it’s still a great day to be out.

The surf eases a bit into Sunday the 30th, down to 5ft, still clean but the energy drops off. Monday the 31st brings a new pulse. The morning is small, but the afternoon picks up to 6ft with a 19-second period and the energy jumps. This is another excellent window, especially for the afternoon session.

Looking at the water temp, it’s sitting around average for this time of year, so no surprises there. You won’t need a full winter suit, but a decent spring suit is a safe bet.

As we roll into September, the first week holds plenty of good surf. Tuesday the 1st has 7ft to 8ft waves with strong energy, still clean. Wednesday the 2nd keeps that same rhythm with 7ft to 7ft surf. Thursday the 3rd eases a touch, but the afternoon is still excellent.

Then there’s a bit of a lull from Friday the 4th into Saturday the 5th. The swell drops back to 4ft and 4ft, and the energy wanes. It’s not terrible, but it’s small. The weekend looks like a wait-and-see.

But hold on, because Sunday the 6th brings it back with a punch. 6ft surf, 15-second period, and light winds. It’s clean and fun. Monday the 7th is okay, but the real kicker is Tuesday the 8th. The morning has a long-period swell at 22 seconds, though the height is only 4ft. The afternoon is where it’s at—swell jumps to 7ft with a 20-second period and strong energy. That’s a proper, long-period groundswell. This will be epic at the reef and point, though you might find it breaking a bit straight at the beachies.

Then Wednesday the 9th finishes the run with 8ft of strong SW swell and a 17-second period. Energy is high. Again, this is big and only for experienced surfers.

So, the standout days are clearly Friday the 28th and then that late kicker on Tuesday the 8th and Wednesday the 9th of September. These are the ones with the size, the power, and the clean conditions. The crowd factor is there too—Nungas is fairly consistent and can get busy, so you might be sharing the peak.

We do have that little dip on the 4th and 5th, a couple of small days, but it’s a short gap in an otherwise solid forecast.

Overall, there’s a lot to work with here. Get on it.

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.
