The Lowdown
Alright, folks, Rusty here. Let’s cut through the noise and look at what this stretch has in store for us at Chapadmalal. It’s a bit of a mixed bag, to be honest. We’ve got a fair bit of waiting to do, but there are a couple of windows that could definitely get the heart rate up.
The next week and a half look pretty bleak, to be straight with you. Through the 21st, we are looking at small, weak surf with poor winds. The energy is just not there, with readings mostly in the double digits and low hundreds (148, 223), and a lot of those days are cross or cross-on. Not worth suiting up for. The swell is small, often under 3ft, and those easterly directions are just not doing anything for the point. The 20th, it's clean but gutless—you'd be paddling for nothing.
Then things get proper messy. Around the 21st and 22nd, we see the swell start to build, but it comes with a whole lot of wind. We're talking fresh to near-gale strength cross-shore winds and heavy cross-chop, with the energy jumping up into the strong range (836, 952). The surf gets up to 6ft to 7ft, but it’s going to be a war zone out there. This is less about surfing and more about survival, or possibly a kite session if you're into that sort of punishment.
Now, for the one true standout in this whole run. Mark your calendars for the morning of Sunday, August 23rd. The forecast shows the swell is up around 7ft from the S, and while the wind is a cross, the energy reading is massive at 1829. That’s a strong, powerful swell. The file even notes that wind and tide are favorable, but the size might be too much for this break. At over 7ft, this is heading into expert territory for sure. A big S swell like that will be hitting the point with some serious intent, but the cross wind could make it a bit of a battle. It’s a standout for size and power, no doubt.
After that, the swell backs down but the conditions improve. Monday afternoon, August 24th looks like the pick of the week. We're looking at 5ft of S swell, clean, with a glassy wind state (5 km/h) and a good energy reading of 629. This feels like the window where it all comes together. The swell direction is SSE, which is pretty much right in the sweet spot for Chapadmalal's optimum SSE direction. It should offer some proper, clean point-break waves. I'd be getting excited for this one.
The rest of the run slides back into the mediocre zone. The last week of August and into September just doesn't have the same punch. There's a long stretch with barely a ripple of energy, and we’re back into the small, weak category (326, 197, 121). The wind on the 27th morning is glassy, but the swell is just a pulse, not worth the paddle.
So, the long and short of it: get through the early junk, be ready for the big, gnarly groundswell on the 23rd if you're an expert, and save your energy for that clean, glassy Monday afternoon on the 24th. That’s the one. The rest is just filling in time. Patience, friends.
Rusty, signing off.

Information about the Chapadmalal Surf forecast
The above surf forecast table for Chapadmalal provides essential information for determining whether the surfing conditions will be good over the next 16 days. 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. If you surf the same spot (Chapadmalal) regularly then make a mental note of the wave energy from the surf forecast table each time you go. 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.
