The Lowdown
Alright, let's get into it. Rusty here, lookin' at what's cookin' for the next couple of weeks.
It's gonna be a lean stretch for a while, with a real quiet spell before things get interesting. The water is sittin' at about 63°, which is pretty much what you'd expect for this time of year, so no surprises there.
The first few days are a bit of a write-off. We've got a few windows of small, weak surf, but nothin' worth paddlin' out for. The combined energy is low, mostly in the double digits, and those ESE 3ft waves on Tuesday the 18th are just messy with a cross-on breeze. Wednesday morning the 19th is glassy but tiny, so maybe a longboard if you're desperate.
We get a bit of a pulse on the 28th of August, with some S/SW swell pushin' in, but the wind is gonna be a killer. Friday afternoon the 28th sees 5ft from the SSW but with a fresh 19 mph cross-on wind, makin' it lumpy and tough. That's a no from me.
The real standout, and the one you've gotta bookmark, is Sunday the 30th of August at Curl Curl. Look, this is a big one. We've got a solid 8ft S swell rollin' in with a very long period of 18 seconds. That's pure groundswell, lots of energy – the combined energy is a whopping 6764, which is insane. The wind is a gentle cross-off from the SSW, so it's gonna be clean. But, and this is a big but, this is a beefy swell. At 8ft, this is expert territory. It's gonna be powerful and the sets will be long. For the experienced crew, this is the best on offer by a long shot. The swell direction matches perfectly with what this break likes.
The followin' morning, Monday the 31st, still has some size left at 6ft from the S, but the period drops to 12 seconds and the wind is light and cross, so the quality won't be as good.
There's a tiny window on Tuesday the 1st of September with a glassy 4ft from the SSE, but it's nothin' to write home about compared to that Sunday. The rest of the first week of September looks like it fades back into mediocrity.
So, to sum it up: the first week is a bust. The second week offers one big, clean, powerful day on the 30th for the experts. Everything else is a gamble on small, ordinary waves.

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.
