The Lowdown
G’day, Rusty here. Let me tell you how it’s looking in feet and fahrenheit.
The next couple of weeks at Curly are a real slow burn. From Saturday the 15th through to Tuesday the 25th of August, there’s basically nothing worth paddling for. Small, choppy, weak waves with poor wind. A few mornings might look clean, like Wednesday the 19th with a 2ft ESE swell and a light westerly, but that’s knee-high mush with weak energy (180 units). You’re looking at a solid eight-day gap of forgettable surf.
Then, on Sunday the 23rd of August, things finally fire up. Curl Curl gets a clean 4–5ft south swell with a 12-second period and decent energy (511 units). The wind is a light west-southwest cross-offshore, so the waves should be glassy with good shape. This is the real standout – solid, clean, and not too crazy for most surfers. A proper winter groundswell.
But after that? It turns huge. From Wednesday the 26th, the swell jumps to 10ft, then 13ft, then 16ft by Friday the 28th – with glassy conditions and a 13-second period. Energy readings hit over 16000 units. That’s expert-only territory – anything over 8ft is strictly for the brave. The long-period south swell will wall up at the beach, but it’s going to be mighty. The following days stay massive with 10–12ft swell through the weekend of the 29th–30th, but onshore winds creep in. Water temp is 62°, which is about 3° colder than average for mid-August – layer up good.
Best advice: Sunday the 23rd is your window. After that, it’s all big-wave territory for experienced crew only.
Rusty out.

Information about the Curl Curl Surf forecast
The above surf forecast table for Curl Curl provides essential information for determining whether the surfing conditions will be good over the next 16 days. A general guide to surfing at Curl Curl can be found by selecting the local surf guide option on the grey menu. Our Curl Curl 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 (Curl Curl) 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 Curl Curl 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.
