The Lowdown

Alright folks, Rusty here. Let’s have a look at what’s on the cards for Chapadmalal over the next couple of weeks.

Right off the bat, I gotta be straight with you – the first week or so is pretty lacklustre. We’re looking at a long stretch of small, weak waves where the conditions just don’t line up. From Saturday the 29th of August right through to the end of that first week, you’ll find tiny little 1ft to 2ft swells, mostly from the east, with combined energy barely cracking 100 (74 to 79). It’s surfable, but it’s very ordinary. The wind is often offshore or clean, but the swell is just too small and weak to get excited about. There’s a window on Saturday afternoon the 29th with a light NW offshore and a 2ft East swell at 10 seconds – that’s your best bet for a beginner-friendly, clean little session if you’re desperate. But honestly, it’s nothing to write home about.

Then we hit a bit of a rough patch. From the 3rd of September, the wind turns onshore and the energy picks up, but it’s messy. Wednesday the 3rd has a 4ft ENE swell but with a 20 km/h cross-onshore wind – chop city. That theme continues, with the swell trying to build but being blown out by strong onshore winds. The standout in this period is actually a bit of a warning: on Sunday the 6th of September, we get a big 10ft South swell at 11 seconds, with combined energy going through the roof at 1870. The wind is cross-shore and the conditions are lumpy, but that swell is simply too big for this spot. This is only for very experienced surfers, and even then, it’s a full-on, heavy day. The Monday morning after that, the 7th, is still a solid 7ft South swell, but again, it’s probably more than most want to handle.

Now, listen. The real highlight, the one that’s got my attention, is Wednesday the 9th of September. We’ve got a clean 5ft SE groundswell rolling in with a 12-second period, hitting a combined energy of 772. The wind is light and offshore from the WNW, 10 km/h. That’s glassy conditions, and the swell is a nice, manageable size for a point break like Chapadmalal. The direction from the SSE is right in the sweet spot for this break. This is the best on offer for the whole run. It’s a solid, clean, fun day. The water temp is about average for the time of year, so no major surprises there.

The rest of the second week trails off again. The 10th and 11th see the swell drop and the wind turn onshore and messy, giving us poor surf. So, to wrap it up: if you’re a beginner, stick to the small, clean windows on the 29th and 30th of August. If you’re experienced and want the best wave, pencil in Wednesday the 9th of September – that’s your day.

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.
