The Lowdown
G’day, Rusty here, looking at the surf ahead for our patch. To be honest, straight up, the next 16 days are looking pretty ordinary. There’s no real standout swell on the cards, and a lot of the time the wind is going to mess things up. We have a long gap from now until Sunday the 13th of September where conditions are not worth paddling out for. After that, there are a few brief windows of cleaner but small surf.
Let’s start with the only break we’ve got to work with: Chapadmalal. It’s a point break with a pretty consistent track record, but for the first week, it’s mostly a write-off. The water temp is sitting at 50°F, which is a touch warmer than normal for this time of year, so at least it’s not freezing.
This Tuesday the 8th of September, the swell is tiny, only 2ft from the south with a short 8-second period, and the wind is cross-off. The combined swell energy is weak (95), so it’s just not worth it. Wednesday the 9th sees a little pulse of 2ft swell from the south, but with a very long 15-second period. That’s a proper groundswell, but at this size it’s barely breaking. Winds are offshore in the morning, so while it’s clean, it’s just too small to get excited about. Combined energy is moderate (164).
The weekend is a no-go. Friday the 11th has onshore wind from the SSE at 16 mph, and by Saturday the 12th, the swell jumps to 7ft from the SSE. That sounds big, but with onshores blowing 22 mph and a short 8-second period, it’s a washing machine. Combined energy is strong (571), but it’s blown out and messy – probably more interesting for kite surfers than proper surfing.
Now, Sunday the 13th of September is the best on offer in the whole run. We get a morning session with 4ft swell from the SSE, a 9-second period, and light WNW winds at 9 mph that are cross-off. The combined energy is moderate (278) and conditions are clean. It’s not pumping, but it’s surfable and the point should offer some lines. Crowds can show up here sometimes, so you might have a few out, but it’s going to be the pick of a pretty quiet period.
From Monday the 14th onwards, it drops back to tiny 2-2ft swell with offshore winds, but the energy is too weak (under 113) to be worthwhile. There’s a slight glimmer on Thursday the 17th with 4ft from the SSE and a 10-second period, with cross-off NW winds, but the combined energy (337) is moderate and it’s only rated as marginal. After that, we’re back to tiny waves below 2ft and mixed wind directions right through to the end of the forecast.
Overall, if you’re desperate, aim for Sunday morning the 13th at Chapadmalal. It’s a small, clean, and workable window, but don’t expect magic. The rest is a write-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.
