Chapadmalal Surf Forecast and Surf Report

Alright, Rusty here. Let’s talk about what we’ve got for Chapadmalal over the next sixteen days.

Overall, it’s a pretty quiet start, with a long stretch of nothing really worth paddling out for. The first week is mostly small and poor. The swell energy is low, and winds are messy. Then things start to build, and there’s a couple of standout windows that look really promising, especially if you’re experienced. Let’s get into it.

We start off Tuesday, 1st September, and it’s flat. Tiny 1ft swell from the east, weak energy (30) and onshore winds. That sets the tone for the next few days – small, weak, and ordinary. Through Wednesday, Thursday, and Friday the swell stays below 3ft with energy in the low double or triple digits, and winds are mostly cross-shore or cross-off. Nothing to get excited about.

Saturday the 5th sees a jump in size – 5ft to 8ft from the SSW, energy hitting 392 to 565 – but the wind is howling from the south, gusting 31 to 50 km/h, so it’s blown out and messy. Not worth it. Sunday the 6th is even bigger with 7ft to 7ft from the SSE and energy up to 869 and 1046, but again cross-onshore winds ruin it. Lumpy and choppy.

Now, Monday the 7th – this is the first real glimmer. The morning shows 5ft from the SSE with a clean, light offshore breeze (WNW, 10 km/h) and energy at 461. The wind is offshore and light, and that’s a major positive for clean conditions. The swell is manageable and the period is 10 seconds, which is solid. This is a decent option for surfers looking for clean, fun waves.

Then we hit a big gap. Tuesday the 8th through Thursday the 10th drops right back down to knee-high waves and weak energy. Friday the 11th brings a big spike – 8ft to 10ft from the SSE, with energy hitting 712 and 1280. But this is flagged as too big for the break. The wind is offshore or cross-shore but the size makes it expert-only. If you’re a seasoned charger, the Friday morning might be your window with clean conditions and serious power.

Saturday the 12th stays big, 8ft to 8ft from the SE, but now with strong onshore winds. Not good.

The real standout is Sunday the 13th. Morning session: 5ft from the SE, period a long 11 seconds, energy at 686, and the wind is light (N, 10 km/h) and cross-off shore. That’s clean, decent size, and good energy. This is the pick of the forecast – a groundswell with real punch, best for point breaks or reefs, but at Chapadmalal it should still shape up nicely. Get out there.

After that, Monday the 14th and Tuesday the 15th drop back to small, weak waves, and Wednesday the 16th is tiny with glassy conditions but barely any energy. Not much to chase.

For the water temperature – it’s not flagged as unusual, so it’s about average for the time of year.

So, to sum it up: the first week is a write-off. The best windows are Monday the 7th morning for clean small waves, and Sunday the 13th morning for the best combination of size, energy, and clean wind. That Sunday is your one to circle.

Rusty.
