The Lowdown
Alright folks, Rusty here. Let’s check out what’s happening with Chapadmalal. It’s been a slow start, but there’s a couple of decent windows opening up.
The next 16 days kick off pretty quiet. The first week, from Monday, August 31st through to September 7th, is mostly a write-off. The swell is tiny and the conditions are poor. The combined energy is just a whisper, (24) to (29) – not enough to get a move on, even with the glassy wind. Even on Monday afternoon and Tuesday afternoon when the wind goes glassy, you’re only looking at 0.4m waves with a short period. It’s a real struggle. When the swell tries to show up on the 4th and 5th of September, the wind is howling cross-shore and onshore, making a mess. By Saturday the 5th, the swell is a massive 4.0m, but with a 45 km/h cross-onshore wind and a combined energy of (4901), that’s a kite-surfing day, not a paddle. The water temperature is about average for the time of year.
Now, the real highlight comes on Monday, September 7th. The morning session is the one to circle. The swell drops to a manageable 1.6m from the SE, the wind goes light and offshore from the N at 15 km/h, and the combined energy is a solid (495). This is your best shot. The point break will be clean and offering up some nice lines. The difficulty is beginner-friendly, so everyone can get a piece. Just be aware that crowds are possible here.
After that, the swell fades fast. The 8th and 9th are small and ordinary. But then on Thursday, September 10th, we get another chance. The morning looks good with a 1.1m ESE swell, a light offshore wind from the W at 10 km/h, and a combined energy of (213). The conditions will be clean, and the waves will be surfable, though less powerful than the 7th. The rest of the second week is a mix of onshore winds and small, choppy waves, so don’t expect much else.
To sum it up: the standout is Monday morning, September 7th. The offshore wind, the drop in size, and the clean conditions make it the best on offer. The 10th is a solid backup. The rest of the time, just keep your board waxed and wait for a better forecast.
Stay stoked, Rusty.
