The Lowdown
Alright folks, Rusty here. Let's get into what's cooking for Chapadmalal over the next couple of weeks. Gotta be straight with you – the first few days are a bit of a write-off, but there's some promise later on if you're patient.
Right now, we're looking at a pretty flat start. The first bit of rideable swell doesn’t really show until Monday afternoon, August 24th, and even then, it's a bit average. We've got a 6ft swell rolling in from the SSE with a period of 11 seconds, and the wave energy is moderate at 643. The water's sitting at 50°, which is a touch warmer than normal for this time of year. But the issue is a light cross-onshore breeze from the East at 6 mph, making conditions choppy. Not the greatest start.
The next morning, Tuesday the 25th, things clean up a lot. The wind swings to a moderate cross-offshore from the North at 12 mph, and the wave heights drop a bit to 4ft from the SSE but with a short 10-second period. The real standout of this early week, though, is Tuesday afternoon into Wednesday. On Tuesday afternoon, the swell drops to 4ft, but it's coming from the SE at a much longer 14-second period, which is proper groundswell. The combined energy jumps up to 679. By Wednesday morning, that SE groundswell is pushing 6ft with the same 14-second period, and the energy is strong at 1083. The wind stays a moderate cross-offshore from the NNE at 16 mph. These are the best conditions in this first stretch – clean, powerful waves for those who can handle a bit of current.
But don't get too excited. There's a big gap after that. From Thursday the 27th onward, the swell drops and stays below 3ft for the better part of a week. We see a brief spike in energy on Thursday morning with a light offshore from the NNW at 6 mph, but the swell is only 4ft from the SE. It's clean, but small.
The next real opportunity doesn't come until the following week, and it looks promising. Tuesday, September 1st, the swell picks back up. Tuesday afternoon has a 4ft swell from the East with a 12-second period and a light cross-offshore wind from the WNW at 6 mph. The combined energy is 338. Again, clean and workable. Then Wednesday morning, September 2nd, sees a fresh offshore breeze from the NW at 19 mph, with a 3ft swell from the ESE at 12 seconds. Nice and clean, but the wind is strong.
For my pick of the whole outlook, I'm looking at Thursday morning, September 3rd. We’ve got a light offshore wind from the NW, only 6 mph, pushing into a 4ft swell from the SSE with a 10-second period. The energy is moderate at 430. The conditions are clean, and the wind is ideal. That’s a solid morning to be out at Chapadmalal point.
After that, the swell hangs around the 3ft to 5ft mark through the 4th and 5th with moderate winds, but nothing that really screams "drop everything." The final few days of the outlook drop back into tiny, weak surf with strong, messy winds. By Tuesday, September 8th, it's a flat, choppy mess with a gale cross-shore. Not worth suiting up at all.
Overall, the best bet in the next 16 days is that Thursday morning, September 3rd. Get on it if you can.
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.
