The Lowdown
Alright, this is Rusty, and I'm gonna give it to you straight. The next couple of weeks are gonna be a real grind. The water temp at Chapadmalal is sittin' about a touch warmer than normal for this time of year, at 50°, and that's about the only good news.
We're in for a long, dry spell of poor surf. From Friday the 14th of August, it's all cross-shore winds, chop, and lumpy conditions. The wave energy is weak to moderate, with numbers like 285 and 120, but it's just not comin' together with the wind.
The first real chance of anything doesn't roll in until Sunday the 23rd of August, and it's a heavy one. Early that morning, the swell is a massive 10 ft from the S with a 12-second period, and the wind is a clean cross-offshore from the WSW at 22 mph. The energy is huge – 2546 – but it's just too big for this break. This is expert territory, and honestly, it's more of a kiteboarding day than a paddle session.
Monday the 24th of August is another big one. The morning sees a 8 ft SSE swell (11-second period) with a clean offshore wind from the W at 16 mph. The energy is 1219. But again, it's too big for the average surfer. The afternoon drops to 7 ft with a still-strong cross-off, but it's marginal.
After that, it's back to onshore winds and tiny, weak swells. The only other time I'd even mention is Wednesday the 26th of August, where the morning goes glassy with a tiny 3 ft SSE swell. It's surfable, but just barely.
So, the honest truth is, there's not a single good session in this 16-day window. The only big swells are too big and too raw for this spot. If the forecasts change, I'll let you know, but for now, it's a good time to take a break.
Rusty.

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.
