The Lowdown
Alright, Rusty here, pulling up the charts for our little slice of surf. Let's see what's on the menu.
First thing you gotta know – we’ve got a consistent run of swell, but it’s the second week that’s got my heart pumping. The water’s sitting at a balmy 85°F , which is a touch warmer than normal for this time of year, so you might get away with a thinner suit.
It kicks off Tuesday afternoon (August 18th) with a clean 3ft SSW groundswell. The period is a juicy 14 seconds, and with a light cross-offshore breeze from the east, it's surfable. The combined wave energy is moderate at 498. Not a cracker, but a fine way to start.
Wednesday morning (August 19th) is a real treat. Glassy conditions, zero wind, and a clean 3ft SW swell at 14 seconds. This is where it gets good – the point will be smooth and lined up. The afternoon turns a bit messy with a cross-on breeze, but that morning session is the pick of the first few days.
We've got a bit of a lull in quality through the weekend and into the start of the next week. The swell drops right down to 2ft by Sunday the 23rd. That long period (20 seconds) groundswell will wrap in, but it’s tiny. You’re looking at ankle-biters, best for the loggers on a glassy morning.
Hold on, because things fire up again. The standout window is from Friday, August 28th. The morning starts with a glassy 3ft SW swell at 16 seconds – clean and inviting.
But the real magic is August 29th and 30th. Saturday morning (Aug 29th) brings a solid 4ft SW groundswell at a very long 17 seconds and glassy conditions. The wave energy jumps to a whopping 1098. This is excellent surf. By the afternoon, it bumps to 5ft with similar glassy wind, and a monster 1230 wave energy. Sunday morning (Aug 30th) is even bigger at 5ft with a 15-second period and 1259 energy. These are expert-level waves; the point will be pumping, with very long, clean sets. For the experienced crew, this is the time.
Through the 31st and into September, the size drops back a touch, but it stays clean and very good, with 5ft to 3ft SSW swell and glassy mornings holding the quality.
So, your two true standouts? Saturday morning and afternoon, August 29th, and Sunday morning, August 30th at Quatro-Once. That's the cream of the crop – big, clean, powerful groundswell, and the wind is perfect. Get ready for a proper session.
Stay wet,
Rusty

Information about the Quatro-Once (411) Surf forecast
The above surf forecast table for Quatro-Once (411) provides essential information for determining whether the surfing conditions will be good over the next 16 days. A general guide to surfing at Quatro-Once (411) can be found by selecting the local surf guide option on the grey menu.

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 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.
