The Lowdown
Alright folks, Rusty here. Let’s have a look at what’s coming our way.
We’ve got a bit of a slow start, but hold tight – a proper window of clean, punchy surf is lined up for the middle of the week. The real standout is a solid morning session on Tuesday, 11 August, with a smaller but glassy dawn on Wednesday, 12 August also worth a paddle. After that, things get messy for a long stretch.
The first real action kicks off Monday afternoon, 10 August, at Chapadmalal. The swell is already chunky at 8ft from the SSE, with a period of 12 seconds – that’s proper groundswell energy. The combined energy is cranking at 2783 (strong wave energy). But the wind is cross-shore from the SW at 12 mph, so it’s gonna be a bit lumpy. This swell is also too big for beginners; it’s pushing into expert territory. The water’s sitting at 51°, which is a notable 4° warmer than usual for this time of year – a real treat for the skin.
The highlight of the whole outlook is Tuesday morning, 11 August. The swell drops to a solid 7ft from the SSE, still carrying that 11-second period (good groundswell). The combined energy is 1413 (moderate to strong). But the big win is the wind: a light breeze from the west at 6 mph, coming cross-offshore. This is going to clean the waves right up. Excellent conditions for experienced surfers. This is the one to circle.
Wednesday morning, 12 August is the next best bet. Swell is a very manageable 4ft from the SSE, 11-second period, and the wind is glass – absolutely dead calm at 0 mph. Combined energy is 740 (moderate). It’ll be tiny but absolutely perfect, glassy faces. A great session for a longboard or a funboard.
Wednesday afternoon sees a bump in size to 5ft from the SSE, with a very long 14-second period, but the wind swings onshore from the SE, making it less inviting. Combined energy jumps to 1554 (strong).
From Thursday, 13 August, right through to the end of the second week, the surf goes pretty ordinary. The winds are mostly cross-onshore or onshore, and the swell drops away to nothing much. There’s a long gap of poor conditions from Thursday morning through to Saturday, 22 August, when a tiny 2ft wave from the east shows up with a gentle cross-offshore breeze – it’s surfable but very ordinary. That’s about a 10-day stretch of mostly flat or choppy water.
The very end of the outlook, on Tuesday, 25 August, has a bit of a pulse: 5ft from the south with a 9-second period, but the wind is a screaming 28 mph from the west, cross-offshore. Combined energy is 738 (moderate). That’s a strong, clean wind, but the swell is short-period and the wind is howling. It might be more of a kite-surfing day than a paddle day.
So, the call is simple: Tuesday morning, 11 August is the best of the lot. Wednesday morning, 12 August is the backup for smaller, cleaner glass. Get on it before the long flat spell hits.
Rusty.

A general guide to surfing at Chapadmalal can be found by selecting the local surf guide option on the grey menu.

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.
