The Lowdown

Alright folks, Rusty here with a good long look at what’s coming down the line. We’ve got a solid run ahead, so let’s get into it.

The window opens this Sunday afternoon and doesn’t really let up. The main spot, and the only one we’re talking about, is Nungas. It’s a reef and point set-up, fairly consistent, and it’s getting hammered by a long-period SSW groundswell. The water’s sitting at a warm 79°F, which is pretty much average for this time of year – no surprises there.

We kick off on Sunday, August 23rd with a solid 7ft SSW swell running at 15 seconds. The wind is a cross-off SSE breeze at 9 mph, so it’s gonna be clean with that slight push. The energy in the water is strong (2587), and the wave comment says it’s for experienced surfers—that 7ft on a point break with a long period is a proper machine but not for the faint-hearted.

Monday, August 24th holds similar size, around 7ft to 7ft, with the same SSE cross-off wind. Tuesday brings a bit of a drop to 5ft in the morning, but that SW groundswell keeps things interesting. By Tuesday afternoon it’s back up to 6ft, and we get a 16-second period that afternoon. You’re looking at clean surf with cross-off winds through the week.

Now, the first real standout comes on Friday, August 28th. That morning we get a solid 8ft SW swell, 17-second period, with a light SE breeze at 6 mph – that’s as good as it gets for the experienced crew. The combined energy jumps to 4343, which is pumping. Nungas is built for this kind of SW groundswell, and with those long gaps between sets, paddling out will be a breeze. The afternoon gets a bit cross-chop, so hit it early.

The surf stays solid through the end of August and into September. Saturday the 29th is a strong 7ft to 6ft, and Sunday the 30th drops to a more manageable 5ft. The long-period pulses keep coming.

Looking into the first week of September, things stay active. Tuesday, September 1st is another standout – 6ft SW swell with a 17-second period and light SE wind at 6 mph. That’s a beautiful clean session with strong energy (2040). Wednesday the 2nd pushes back up to 7ft with the same light cross-off conditions.

We roll into the second week and the consistency holds. Early September sees 6ft to 7ft SSW swells, and the wind stays favourable with 6 to 9 mph cross-off breezes. The energy stays moderate to strong, and the conditions are clean.

One more highlight: Saturday, September 5th brings a 6ft to 7ft SSW pulse with a 16-second period. Morning is glassy with light SE wind. Nungas will be firing again.

Right through to Monday, September 7th, the tail end of the run still offers 5ft to 5ft SW swells, though the wind swings a little cross later in the afternoon. But the mornings are clean.

Overall, if you’re an experienced surfer, Nungas is your spot. The best bets are the Friday morning of August 28th and Tuesday, September 1st. Crowds are possible here, but the quality of the waves will make it worth sharing.

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.
