The Lowdown
G’day, it’s Rusty. Let’s talk about the next couple of weeks—and brace yourself, because it’s mostly a flat, frustrating run. There’s a long stretch where the surf just isn’t doing anything, and you’ll be waiting days for any kind of pulse.
First up, Monday and Tuesday are blown out. Onshore winds, messy chop, no size to speak of. You’re better off doing anything else. Then Wednesday morning on the 16th—that’s the window. Wind goes offshore, light, clean. Swell pushes to 1.7m from the SSE, 9-second period, and energy’s sitting at 541—moderate but the most power we see all period. Chapadmalal is a point break, and that SSE direction should give it some shape. Water’s 10°, a touch warmer than normal, so it’s not too brutal. That’s the one to get out for.
Thursday is smaller, still offshore, but only around 0.9m. It’s rideable, but nothing special. Then Friday through the following Tuesday is basically dead. Small waves, weak energy, messy directions. A few clean moments but no push. You’ll be sitting on your board doing nothing.
Tuesday the 22nd morning brings a bit of life—1.4m from the south, 10-second period, light offshore wind. Energy’s moderate at 427. It’s clean and could be fun, but the afternoon turns cross-shore and messy. That morning window is all you get.
After that, the 23rd onward is a grind. Poor surf, weak pulses, and winds that just don’t cooperate. There’s a tiny south swell around the 29th—1.2m—but it’s onshore and choppy. Forget it.
So the short story is: one standout morning on the 16th, maybe a glimpse on the 22nd, and a whole lot of nothing in between. If you’re flexible, chase that Wednesday. Otherwise, it’s a waiting game. Forecasts can change, but right now, it’s lean.
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.
