The Lowdown
G’day, Rusty here. Let’s break down the surf at Chapadmalal for the next couple of weeks. There’s a slow start, a couple of clean windows, and a few proper standout sessions if you’ve got the patience.
Water temp’s about 51°F, which is a touch warmer than usual for the season – not a huge shift, but worth noting if you’re not in a thick suit.
The first few days are a write-off. Tuesday arvo is a mess with a 6-foot S swell and 22 mph cross-on winds; combined energy is 369 (moderate), but it’s lumpy and poor. Not worth a paddle.
Then we get a real highlight. Wednesday morning, September 16 – that’s the one. The surf is a clean 5-foot south swell at 9 seconds, and the wind is light north at 6 mph, cross-off. Combined energy is 453 (moderate). The lines will be smooth and well-shaped. Crowds can pop up at Chapadmalal now and then, so if you get in early, you’re golden. This is the best early session.
Thursday September 17 stays clean in the morning with a 3-foot SSE swell and offshore NW winds at 16 mph. It’s smaller, but the wind’s straight off the land, giving you glassy conditions. Combined energy drops to 120 (moderate) – surfable but not pumping.
Then there’s a long dead stretch. From Friday September 18 through Monday September 21, the surf is tiny – under 2 feet – with weak energy (as low as 19-44) and poor conditions. That’s about 4 days of nothing.
Now Tuesday, September 22 – circle this one. Morning brings a clean 5-foot S swell, 10-second period, and light WSW winds at 6 mph (cross-off). Combined energy is 422 (moderate). That’s a cruisey, well-shaped point-break kind of day. The longer period means good energy and longer gaps between sets – perfect for this spot.
Wednesday September 23 keeps the offshore flow going (NW and NNW, 16-19 mph) with a 4-foot SSE swell at 11 seconds. Energy is 363-401 (moderate). Clean and workable.
From Thursday September 24 through Monday September 28, things get messy – cross or cross-on winds, swell dropping to 2-3 feet, and poor conditions. One exception is Saturday September 26: a massive 8-foot SSW swell, but with cross-on 13 mph winds and combined energy of 1166 (strong). The surf report says it’s too big for most – experts only, and it’s choppy.
The final days, Monday September 29 and Tuesday September 30, bring chest-high S swell (6-6 feet) but with cross-on winds, so the quality’s iffy. Energy is moderate to strong (571-761), but the wind’s spoiling it.
Bottom line: hit Wednesday morning September 16 for the early clean session, and lock in Tuesday morning September 22 – that’s the real standout with light winds and a fun point break.
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.
