Chapadmalal Surf Forecast and Surf Report

Alright, Rusty here. Let’s have a look at what we’ve got for this stretch of coast.

First thing to mention – the water temperature at Chapadmalal is currently running at 50.7°F, which is a touch warmer than normal for this time of year. Not a massive jump, but you’ll feel it’s a little more comfortable than usual, so you can get away with a thinner suit if you’ve got one.

The opening Monday is actually the pick of the near-term. Monday morning, September 7th, sees a clean 3.6ft SSE swell, period around 8 seconds, and NNW offshore winds blowing at 12 mph. The combined swell energy is moderate at 222, and with that offshore wind keeping the surface glassy, this is very surfable for a beginner-friendly point break. The swell direction is straight from the optimum SSE direction that this spot likes. It’s not a massive day, but it’s clean and fun. Crowds are possible here sometimes, so keep an eye out.

Monday afternoon holds similar conditions – same clean offshore wind, same 3.6ft SSE swell, slightly more energy at 240. A solid first day.

Tuesday the 8th drops off quickly. Tuesday morning sees the swell crash to just 1.6ft from the south, with moderate offshore wind but poor conditions overall. Tuesday afternoon is even smaller at 1ft with a 12-second period from the SSE, but the cross-offshore wind can’t save it. Not worth paddling out.

Wednesday the 9th offers a bit of a tease. Morning has a 2ft S swell with a long 15-second period – that groundswell potential – but it’s weak, with only 164 combined energy. Offshore wind from the NW at 16 mph keeps things clean, but the swell is just too small. Same story Wednesday afternoon – 2.3ft, 13-second period, gentle cross-offshore breeze, but still ordinary.

Thursday the 10th is more of the same. Morning sees 2ft from the south, light offshore wind, but energy is low at 74. Afternoon turns poor with a cross-onshore breeze from the east.

Friday the 11th is a write-off. Strong onshore winds from the SSE, gusting 25-31 mph, with a building but junky 6.2ft SSE swell. That’s messy and unsurfable.

Saturday the 12th gets bigger but uglier. 8.2ft SSE swell in the morning, combined energy jumps to 980 – solid power – but the wind is howling onshore at 22 mph. That’s a no-go for paddle surfing; honestly, kite surfers would have a field day here with that wind and size. Afternoon stays poor with cross-onshore wind and a 7.9ft lumpy swell.

Now we get a nice window. Sunday the 13th morning – clean again. NNW offshore wind at just 6 mph, 4.3ft ESE swell, period 8 seconds, combined energy 433. That’s a proper surfable morning. The swell direction isn’t the absolute optimum (SSE preferred), but it’s still good. Afternoon is marginal with a cross-offshore breeze, but still clean.

Monday the 14th looks good too. Morning has a 3.3ft ESE swell, period 11 seconds, combined energy at 292, with moderate offshore wind from the NNW. Clean and consistent. Afternoon holds with 3ft and moderate offshore wind from the NW. Two solid days back to back.

Tuesday the 15th – steer clear. Strong cross-shore winds from the SW at 28-31 mph ruin everything. Swell is 4.3-4.6ft from the south, but the wind chops it up badly.

Wednesday the 16th is a standout, but only for experts. The swell hits 6.9ft from the south, with a 12-second period, and combined energy is a massive 1236 – that’s strong. Winds are cross-offshore from the WNW at 19 mph, keeping the surface clean. But 6.9ft at a point break? That’s big, especially for a beginner spot. Only experienced surfers should even look at it.

Thursday the 17th is even bigger. 9.8ft SSE swell, 14-second period, combined energy over 3000 – very strong. Winds are light offshore from the north in the morning, building to a moderate cross-offshore in the afternoon. This is huge for the spot. Only for experts, and even then, it’s a heavy day.

Friday the 18th drops back to 5.2-5.2ft SSE swell, long 11-second period, but winds are fresh and cross-offshore. Marginal conditions – the swell is still significant, but the wind isn’t ideal.

After that, the surf fades. Saturday the 19th morning offers a tiny 2.6ft SSE swell with gentle offshore wind, but combined energy is weak at 114. Ordinary. Saturday afternoon turns poor. From Sunday the 20th through Tuesday the 22nd, it’s mostly small, weak, and messy – you’re looking at a long stretch of flat or poor conditions.

The best of the whole window? Monday the 7th for clean, fun, beginner-friendly waves. And Wednesday the 16th if you’re an expert and want to wrestle a bigger, powerful swell in clean conditions. That second week call on the 16th is promising but less certain this far out.
