The Lowdown
G’day, Rusty here, and I’ve got a look at what’s shaping up for the next couple of weeks. It’s a bit of a slow start, a real slow start actually—there’s no surf worth chasing until we get to Sunday afternoon, the 13th of September, so we’re looking at a few days of flatness before anything kicks off. But once it does, there’s some clean, small-wave fun on the table if you know where to go.
The best of it, and the standout for the whole run, is Quatro-Once (411) . This spot is a consistent, exposed point break that loves a SSW swell, and the water’s sitting at 84° – that’s a touch warmer than what you’d usually expect for this time of year, so you can leave the thick wetsuit at home. The swell energy over the opening sessions is pretty light, with readings around 335 to 372 (moderate energy) but it’s all about the quality here.
Sunday afternoon, September 13 – It’s tiny, just 2ft of SW swell at 13 seconds, but the wind is glassy and light. It’s a marginal call, but if you’re keen for a gentle paddle, it’s a start.
Monday, September 14 – Morning and afternoon both deliver glassy conditions and tiny 1ft to 2ft of SW swell. The period jumps up to 18-19 seconds, so it’s proper groundswell, but it’s small enough that you’ll be on a longboard. The combined energy is around 288-301 (low-moderate) but the lack of wind means it’s clean.
Tuesday, September 15 – Now we’re talking. The morning sees 2ft of SW swell with a 12 mph NNE offshore wind, clean and lined up. Afternoon kicks up a notch: 3ft of SW swell, 18 seconds, gentle offshore from the NE at 9 mph. The energy climbs to 582 (moderate) and the wave comment says it’s looking very good. This is a solid small-wave session for a point break.
Wednesday, September 16 – The pick of the first week. Morning has 4ft of SW swell at 16 seconds, with a gentle 9 mph NNE offshore wind. Combined energy hits 713 (moderate-strong). Afternoon holds similar, at 3ft. The winds are clean, the swell is punchy for the size, and this is a great day to be out.
Thursday, September 17 – Still some clean 3ft of SW swell in the morning with light offshore wind, but the afternoon gets messy with a cross-onshore breeze. Not your best session.
There’s a bit of a lull from Friday to Saturday, with smaller swell and cross-shore winds, but hang in there.
Sunday morning, September 21 – This is the absolute standout session. Flat calm, glassy, 3ft of SW swell at 18 seconds, and the combined energy is 633 (moderate-strong). The wave comment says “very good surf conditions,” and with the point break handling the long period beautifully, this is the day to clear your schedule.
Tuesday morning, September 22 – Another beauty. 3ft of SW swell at 16 seconds, with a light cross-offshore breeze from the east. Clean, fun, and the energy’s at 569. The crowd situation at Quatro-Once can get a bit busy sometimes, but on a weekday morning like this, you’ll likely have plenty of room.
Saturday morning, September 27 – Into the second week and this one shines. 5ft of WSW swell, 9 second period, with a 6 mph NE offshore wind. The combined energy reads 618 (moderate-strong) and the conditions are clean and glassy. Afternoon on the 27th keeps the glassy vibe with 4ft. A great way to end the window.
There’s a bit of a funky day on the 24th with a 6ft of SW swell but a period of only 7 seconds—short period, crumbly, and the wind is cross-onshore. Not worth the paddle.
For the real standout session: Sunday the 21st of September, morning at Quatro-Once. Glassy, 3ft of clean SW groundswell, good energy, no wind. Perfect.
Rusty.
