The Lowdown
G’day, Rusty here. Look, I’ll be straight with you – this outlook for Chapadmalal is a bit of a mixed bag. We’ve got a window of decent surf, but you’re gonna have to be patient and pick your moments. The water’s sitting at 50°F, which is a touch warmer than normal for this time of year, so that’s a small win.
The first real chance to get wet comes on Sunday, 13th September. It’s not going to be huge, but the conditions are looking prime. We’ve got a clean, 4ft south swell rolling in, with a nice 11-second period. That’s a proper groundswell, so expect some shape. The wind is blowing offshore from the WNW at 9 mph, and that’s gonna keep the faces glassy. It’s a point break which will suit that long-period energy nicely. The combined energy is moderate at 336. It’s a beginner-friendly wave at this size, but there might be a few other folks around as crowds are sometimes there. Sunday afternoon is still surfable but dropping off to 3ft with lighter offshore wind.
Now, nothing else in this run really stands out as a top-shelf session. We’ve got a few other clean moments, but the swell is too small or the wind too strong. For example, Wednesday morning the 16th has some solid 5ft from the SSE with clean conditions and a light breeze, but the period is short at 8 seconds, so it’ll be a bit mushy. Still, it’s a wave. The combined energy is 274 which is moderate.
Beyond that, things get messy. There’s a big gap from the 18th with tiny, weak surf and then a lot of strong, cross-shore wind through the 21st and 22nd, with a 7ft swell on the 22nd, but it’s blown out by 28 mph cross-shore winds. That setup looks more interesting for kite surfing than paddle surfing. On the 25th, we see some clean 3ft waves, but the wind is a fresh cross-offshore breeze, so it’s not perfect.
The biggest problem here is that the spot itself is fairly consistent, but the wind and swell just don’t line up often enough to call any other day a standout. That Sunday is your pick.
Rusty.
