The Lowdown
G’day, Rusty here. We’ve got a solid run of surf coming up at Roches Noires, a reef break that’s consistent and works best on a SW swell. The water’s sitting at 77°, which is a touch warmer than normal for this time of year – nice for long sessions.
The week kicks off Monday the 17th with a long-period SW groundswell, 4ft, but a bit of a mixed bag. The morning is clean enough with a light offshore, though the forecast calls it marginal. The afternoon shapes up better with a cross-off breeze and clean waves, rated for experienced surfers. Tuesday the 18th drops off to 3ft and 3ft, still clean and cross-off in the arvo, but the energy is moderate, so it’s just small fun stuff.
Wednesday the 19th sees the swell drop to 3ft, but the afternoon goes glassy – dead calm. Energy is weak, but if you’re keen for a longboard, it’s smooth. Thursday the 20th stays small and glassy, 3ft to 2ft, with moderate energy. Not pumping, but clean.
Now, Friday the 21st is where it starts to get interesting. The swell lifts back to 4ft, long-period SW at 14 seconds, with glassy conditions all day. Energy is moderate, and it’s lining up nicely. Saturday the 22nd pushes up to 5ft, still glassy, with energy climbing. This is the first standout of the run – clean, building swell, and that reef will be handling it well.
The real standout is Sunday the 23rd. The swell jumps to 8ft, SSW direction, with long 14-second periods. Energy is strong, and it’s glassy all day – morning and afternoon. This is for experienced surfers only; it’s big and powerful. The reef will hold it, but it’s not for beginners. Monday the 24th stays solid at 6ft to 6ft, clean and glassy, with strong to moderate energy. Tuesday the 25th holds at 5ft to 5ft, though the afternoon gets a cross-on breeze, making it a bit messy.
Second standout – Wednesday the 26th. Another big day, 8ft, long-period SSW, with glassy morning and a clean cross-off afternoon. Energy is strong. Again, expert territory. Thursday the 27th backs off a bit – 6ft in the morning with a cross-on breeze, but the afternoon goes glassy at 5ft, strong 16-second period, energy at 2198. Clean and powerful.
Top standout of the whole period – Friday the 28th. The swell hits 12ft in the morning, glassy, with energy over 4000. That’s very strong wave energy. The afternoon drops to 10ft but goes cross-shore, a bit more rippled. This is for proper experts only – big, heavy, and long-period. It’s a beast.
Saturday the 29th drops to 7ft with onshore winds, then 6ft in the afternoon with cross-shore. Still moderate to strong energy, but the wind’s not dialled. Sunday the 30th settles back to 4ft glassy in the morning, and 2ft in the afternoon with a very long 19-second period – that’s a weird combo, tiny but super-long, will likely break straight at the beach but the reef might pick it up. Monday the 31st gets a nice 5ft to 4ft SW groundswell, glassy both sessions, strong energy – a clean end to the run.
Tuesday the 1st of September fades to 4ft with cross-onshore and cross-shore winds, weak energy, not worth paddling out.
Overall, the best windows are Sunday the 23rd, Wednesday the 26th, and especially Friday the 28th – all big, glassy, and powerful. Stick to those.

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 Roches Noires 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.
