The Lowdown
G’day, I’m Rusty. Let’s cut straight to it. Over the next 16 days, we’ve got two brief windows of clean, surfable waves, but the rest of the run is looking pretty average or blown out. The first chance comes on Thursday the 20th of August, with a small but clean morning session. The real standout, though, is Tuesday the 25th of August – glassy conditions and a modest bump in size. After that, we’re looking at a long stretch of onshore, messy conditions, and then a big swell event late in the month that’s way too meaty for this spot.
Kicking off at Curl Curl (Curl-Curl), the water temp is sitting at 63°, which is about 1° cooler than normal for this time of year – nothing wild, just a touch on the chilly side.
Thursday morning the 20th of August has some clouds, a light N wind at 9 mph blowing cross-offshore, keeping things clean. Swell is only 2 ft from the ESE with a short period of 8 seconds – it’s small, but it’s surfable. Combined energy is weak at 148. Not a ripper, but a chance to get wet.
Friday morning the 21st of August is your next look. Cloudy, NW wind at 9 mph blowing straight offshore, so the surface is glassy. Swell is 3 ft from the ENE but period is a short 6 seconds, and energy is very weak at 55. Ordinary waves, but clean.
Now for the best of the run: Tuesday the 25th of August. Morning and afternoon both have light rain but the wind goes dead calm – glassy, zero wind. Swell picks up to 5 ft from the NE in the morning (period 7 seconds, energy 229), and 4 ft from the ENE in the afternoon (period 8 seconds, energy 207). That’s moderate energy, clean as a whistle, and the best we’ll see. This is the standout session. Curl Curl is an exposed beach break, and with the swell direction shifting from the ENE, it’s not the optimum direction (SE is best), but the glassy conditions make up for it. Crowds are *often* here, so expect company.
After that, Wednesday the 26th of August sees strong winds of 28 mph from the W and SSW – messy, choppy, and not worth paddling out. The run from Thursday the 27th of August through to the end of the month is a mixed bag of onshore winds and poor surf quality.
Then we hit a massive swell event from Sunday the 30th of August right through to Wednesday the 2nd of September. Swell heights climb from 10 ft to 16 ft, with periods up to 14 seconds, and combined energy readings into the thousands – up to 15,476. This is expert-only territory. The wind is cross-onshore from the ENE at 9–16 mph, so it’s choppy and messy. Honestly, this setup looks more interesting for kite surfing than paddle surfing. For most surfers, stay out of the water.
After that, Thursday the 3rd of September drops back to 7 ft from the SE with period 11 seconds, but the wind is still cross-onshore, and conditions are marginal.
To wrap it up: the only solid window to plan for is Tuesday the 25th of August – glassy, clean, and surfable. Everything else is small and ordinary, or way too big and blown out.
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.
