The Lowdown
G'day, Rusty here. Look, I'll be straight with you—this is shaping up to be a tough stretch for a paddle. The first week or so is a write-off with hardly anything surfable, and while there's a little light at the end of the tunnel, we've got a long wait for it.
The forecast kicks off with a gap of nearly nothing. From Friday the 11th right through to Saturday the 20th, it's a real mixed bag of poor conditions. You'll see some swell pop up, like a 6.9ft on Saturday the 12th, but it's accompanied by strong onshore winds from the SSE at 19 mph making a mess of it. That's a lot of energy (602) going to waste. The only real glimmer in that first week is Sunday the 13th morning. We get a clean, 3.6ft SSE swell with a solid 11-second period and light offshore wind from the W at 6 mph at Chapadmalal (point). That's the best of a bad bunch early on, with moderate energy (348) and the potential for some clean little waves. But it doesn't last, and the following days are back to choppy, windy junk.
The second week isn't much kinder. We've got another gap of poor surf until Monday the 21st morning. That morning, a light offshore NW wind at 12 mph blows over a 3.9ft E swell with a 6-second period. The energy is weak (116) and the period is short, so it's not going to be pretty, but it's the first time the wind is actually helping. It's surfable, but very ordinary.
Then, on Friday the 25th afternoon, the swell tries to push back in. A 5.9ft SSW swell with a 6-second period rolls in, but the wind is a strong cross-shore SW at 22 mph, making it lumpy and poor. The energy is moderate (274), but the quality just isn't there.
Honestly, the standout, if you can call it that, is that Sunday the 13th morning. That's your best chance for a clean wave with that 3.6ft SSE swell and light wind. The water temperature is about 50.7°F, which is a touch warmer than normal for this time of year, so you might not need the thickest gloves. The rest of the window is a real grind, with most days offering nothing but chop and onshore slop. For a point break that needs a clean line, the wait will be worth it if that Sunday delivers.
Stay keen.

A general guide to surfing at Chapadmalal can be found by selecting the local surf guide option on the grey menu. Our Chapadmalal 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.

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 Chapadmalal 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.
