The Lowdown
Alright mate, Rusty here. Let’s talk Curly in feet and miles per hour.
We’re looking at a pretty slow start. Thursday morning brings a south swell around 8ft, but the wind is cross and messy – the energy is heavy (1080) but it’s not clean. Water temp’s about 64°F, nothing wild for this time of year.
Friday drops to about 6ft, still south, but the wind stays cross or onshore. It’s just average.
Saturday 12 September morning is the first real highlight. Swell drops to a clean 4ft from the south with a 12-second period – that’s groundswell, 614 energy – and the wind goes glassy. That’s as clean as it gets for an exposed beach. Best session of the first week.
Sunday and Monday fade to around 3ft to 3ft. It’s small and weak. Tuesday through Friday morning the 18th is a long stretch of poor or marginal surf. Don’t bother.
Now, Saturday 19 September morning – watch out. A massive 12ft south swell with a 10-second period and light offshore wind. That’s 2576 of raw energy. But for a beginner-friendly spot like Curly, that’s too big. Only for experts. The morning is clean, but it’s a beast.
Sunday 20 September morning is the other standout for experienced surfers: 7ft south swell, 11-second period, light offshore, and 1045 energy. Clean and powerful. Not for the faint of heart.
After that, it fades. There’s a pulse on Friday 25 September morning with a 8ft SSW swell, short 7-second period, but clean with light offshore (629 energy). It’ll be quick and bumpy. The afternoon shows a monstrous 16ft south swell – 6281 energy – but it’s too big for Curly.
Best bets: Saturday 12 September morning for a glassy, friendly session, and Sunday 20 September morning for the crew who want power. Crowds are likely, but the conditions will make it worth sharing the lineup.
Rusty.

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.
