The Lowdown
Alright folks, it’s Rusty here, and I’ve been staring at the charts for the next couple of weeks. It’s a bit of a slow-burn story for this stretch, with some real gems hidden in the mix for patient souls.
We’re looking at Quatro-Once (411) as the sole player on the board this forecast period. It’s a point break, perfect for beginners getting their feet wet, and it’s consistent, which is a good thing because we’re going to need that reliability. The water is sitting at a balmy 84°, a touch warmer than normal for this time of year, so you can leave the thick wetsuit at home.
The first real call to action is on Saturday, September 14th. The morning session is the pick of the early days. We’ve got a clean 1ft SW groundswell, with a very long period of 19 seconds – that’s proper energy rolling in (312 combined energy). The wind is a slight cross-offshore from the ESE, keeping the surface glassy. This is a morning for the log or a mid-length; the long period means the sets will be lined up and easy to read at this point, with long lulls between them for an easy paddle back out.
Things really start to cook as we head into the middle of the following week. Keep an eye on Tuesday, September 16th. The afternoon is where it’s at: the swell bumps up to 3ft from the SW, that same long-period groundswell, but the energy jumps to a solid 594. The wind goes glassy calm, and the call is for very good conditions. This is a standout session for a small-wave performance board.
Then, Wednesday, September 17th’s morning session is the absolute king of this outlook. We’re looking at a 4ft SW groundswell with a long 16-second period, packing 708 points of combined energy – the strongest of the entire run. Combine that with glassy, calm conditions from the ESE, and you’ve got the makings of the best waves of the fortnight. It’s a beginner-friendly size, but the quality will have everyone smiling. Expect a few other folks around though; the word gets out when Quatro-Once starts reeling.
We go through a bit of a rough patch mid-period, but there are more clean windows. The mornings of Saturday, September 20th and Sunday, September 21st are both showing glassy conditions with solid, long-period swell, before the wind turns onshore in the afternoons. The Monday, September 22nd morning is another flat-calm beauty with 3ft of SW swell.
Further out, we have a couple of interesting pockets. The morning of Sunday, September 28th sees a glassy 2ft SW groundswell with a very long 17-second period – a reminder that the ocean is still breathing even when the size is small.
Forget the second week’s afternoon sessions – the wind gets messy. Stick to the glassy windows I’ve called out, and you’ll be sorted. The standout is hands-down the Wednesday, September 17th, morning session at Quatro-Once. Don’t sleep on it.
Rusty.

Further information to help with frequently asked questions about our surf forecast for Quatro-Once (411) 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.
