The Lowdown
Alright, surfers, Rusty here, looking at the charts for our stretch of coast. It’s a mixed bag coming up, so let’s break it down.
The first thing that jumps out is the water temp at our main spot, Chapadmalal. It’s sitting at 51°, which is a couple of degrees warmer than usual for this time of year. Not a huge deal, but you might not need the thickest hood.
We’ve got some rideable surf on the menu right away. Tuesday morning (August 11th) is the standout early call. We're looking at a solid 7ft of SSE swell, with a strong 11-second period. The energy is serious, and the wind is light and offshore-ish from the WSW. It’s going to be a bit raw and powerful—this is for experienced surfers only. The crowd could be around, so pick your peak wisely. The conditions will be clean, but it's a lot of water moving.
Tuesday afternoon drops off a bit, with the swell easing to 6ft and the wind turning more cross-on. It’s not as inviting.
Wednesday morning (August 12th) shapes up nicely. The swell settles to 4ft from the SSE, the period is a long 11 seconds, and we’ve got a glassy, clean morning with next to no wind. This is a much more user-friendly option, especially if the big Tuesday morning was too much.
Wednesday afternoon is a write-off, with the wind going cross-on and the period jumping to 14 seconds, which can cause things to close out a bit.
Then the wheels fall off. From Thursday morning (August 13th) right through the weekend and into early next week, it’s poor. Winds are onshore, chop is up, and the swell is small and messy. Don’t bother getting the board wet. It’s a stretch of a few days with nothing on offer.
There is a glimmer on Tuesday morning, August 18th. It’s a small but clean 4ft from the S with a cross-offshore breeze. But it’s followed by poor conditions again. The rest of that week stays small and junky.
Looking further out, there’s a pulse showing up around Tuesday, August 25th. The swell builds to 5ft from the SSE with a long 13-second period. It’s a promising sign, but it's over a week away, and the winds are predicted to be messy. It could be good, but I’d say it’s a “keep an eye on it” situation. The next morning, August 26th, still has some size at 5ft, but the period drops a touch.
All in all, for the next 16 days, we've got two real windows to consider: Tuesday morning, August 11th, for the powerful stuff, and Wednesday morning, August 12th, for the cleaner, more manageable session. Everything else is either flat, blown out, or just not worth the hassle.
This is Rusty, signing off. Stay stoked.

Information about the Chapadmalal Surf forecast
The above surf forecast table for Chapadmalal provides essential information for determining whether the surfing conditions will be good over the next 16 days. A general guide to surfing at Chapadmalal can be found by selecting the local surf guide option on the grey menu. Our Chapadmalal surf forecast is unique since it includes wave energy (power) that defines the real feel of the surf rather than just the height or the period. If you surf the same spot (Chapadmalal) regularly then make a mental note of the wave energy from the surf forecast table each time you go. 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.
