The Lowdown
Alright folks, Rusty here. Let’s get into it for Chapadmalal. We’ve got a bit of a wild ride ahead, with a real mix of powerful swell and tricky winds, so you’ll need to pick your moments carefully.
The next few days are a write-off, but hold tight. Thursday the 20th is a mess with a fresh cross-onshore breeze and weak, short-period energy, so don’t even bother. Friday the 21st sees bigger swell rolling in, but those cross-shore winds are going to keep it lumpy and unrideable.
Now, Saturday the 22nd is where things get interesting, but it’s not for the faint of heart. We’re looking at a serious injection of energy with a combined energy reading of 2653, which is substantial. The swell is 10ft from the SSW with a 10-second period, and the wind is clean cross-offshore. However, that’s too much water for this point break and it’s really only for the most experienced crew. The same goes for Saturday afternoon, with a 8ft swell from the south.
Sunday the 23rd is a hard pass. The swell jumps to 12ft with a very long 15-second period from the SSE, but the wind swings cross-onshore, making it a lumpy, blown-out mess despite the huge energy. Not worth it.
Monday the 24th morning is a real tease. The swell is still a solid 7ft from the SSE, but it’s glassy. The wind is dead calm, which is a major positive. But again, the size is pushing the limits for this spot, so it’s a big-wave day for experienced surfers only. The afternoon sees the wind turn, and the quality drops off.
From Tuesday the 25th through to Wednesday the 27th, the swell drops significantly, but we get some clean conditions. Tuesday morning has a 4ft swell from the SSE with a clean cross-offshore wind, but the energy is moderate. The afternoon on Tuesday gets a bit more interesting with a 5ft swell from the SE and a 14-second period, which has good energy. Wednesday the 27th morning is the real standout of this quieter period: a 3ft swell from the SE with a 12-second period and a gentle offshore wind. The water is a touch warmer than normal at 51°, which is nice. It’s small but clean, and this point break handles that well.
The end of the month and into September is a mix of small, clean conditions and some building energy. Thursday the 28th and Friday the 29th are very small with poor surf. Saturday the 30th has a glassy 2ft swell, but it’s tiny. There’s a gap of a few days here with nothing worth paddling out for.
The real buzz for the end of the forecast window is Tuesday the 1st of September. The morning brings a 5ft swell from the ESE with a 9-second period and a gentle offshore wind. Clean, surfable, and a solid size for the average surfer. The energy is moderate. Then, the real highlight of the entire forecast is on Wednesday the 2nd of September afternoon. The swell is 6ft from the SE with an 11-second period, a gentle offshore wind, and excellent conditions. The combined energy is 1070, which is strong. This is the best looking session on offer.
The pick of the whole period? I’d be looking at the afternoon of the 2nd of September for the best combination of size, clean conditions, and quality. The morning of the 1st of September is a solid second option for a fun, clean session.
Rusty out.

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.
