The Lowdown

G’day, Rusty here. Let’s be straight with you—this stretch of coast isn’t exactly firing. For most of the next two weeks, we’re staring at mushy, weak, or just plain messy conditions. There’s one small window that stands out, but even that’s only for the patient ones.

We kick off with a bit of nothing on Monday the 14th—small 2ft SSW swell, offshore wind, but it’s gutless and the energy is weak (133). Tuesday the 15th gets a bit more size, 4ft in the morning and 6ft by the afternoon, but the wind goes cross and cross-on, and it’s lumpy and poor. That 6ft is pushing it for anyone not solid, and the short 8-second period doesn’t help.

Then comes the standout. Wednesday the 16th morning is your best bet of the whole run. Chapadmalal (Buenos Aires) picks up 5ft of south swell at 9 seconds, with light NNE cross-off wind—clean, rippable conditions. The combined energy is solid at 443, so there’s some push behind it. The afternoon drops a touch to 5ft, still clean, but the tide might mess with it. If you can get out early, that’s your session.

After that, it fades fast. Thursday the 17th has 3ft offshore—clean but weak, energy down to 104. Friday through Sunday the 18th-20th is all under 3ft, mostly tiny and poor. The period drops to 5-6 seconds, so it’s chopped-up slop. By Monday the 21st, we’re still in the gutter.

The following week—22nd to 29th—is more of the same. A brief pulse on Tuesday the 22nd morning brings 3ft at 9 seconds, but it’s marginal and the cross-shore wind messes it up by afternoon. Then it’s back to small, onshore, or weak conditions. The 25th has 4-5ft but with rain and onshore wind—poor quality.

Bottom line: this isn’t a run for the faint-hearted. The water’s about average for this time of year—nothing crazy warm or cold. Crowds will be spotty at best, and given how inconsistent it is, you might have the place to yourself. But don’t expect any magic. The only real shout is Wednesday morning—get it while it’s clean. Otherwise, keep the board in the car and wait for the next system.

Signing off, 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.
