The Lowdown
Alright, this is Rusty. Let's fire up the outlook for Rockpile, starting right now.
Alright, look, if you're hanging out for a proper session at Rockpile, you're gonna need some patience. The first week or so is looking pretty average. The wind is mostly cross-on or cross, and the swell is all over the place, but it generally lacks punch. The water temp is about what you'd expect for this time of year, so nothing wild there.
Friday, August 28th, we kick off with a tiny 2ft SW groundswell, with a long 16-second period. The energy is weak (391). The wind is onshore, so it's gonna be a bit of a struggle. Not one to get excited about. Saturday the 29th lifts a little to 4ft, still that long-period SW groundswell, but the wind is cross-on, chopping it up. The energy is moderate (649), but the conditions are just poor.
We go through a whole run of days – from Sunday the 30th right through to Sunday, September 6th – where the reports are all "marginal" or "poor." The swell hangs around 2ft to 4ft on average, but it's plagued by cross-onshore winds and a lot of chop. There's a small window on Wednesday morning, September 2nd, with a 2ft SW swell and a light breeze, but the energy is still moderate (500) and the conditions are just "light cross-onshore with small wind ripples." It's not going to be all-time.
Now, pay attention to Tuesday, September 8th. That's when things get interesting. The morning starts with a 5ft SSW swell, energy jumping to 830, and a light breeze. By the afternoon, the swell builds to 6ft, the energy cranks up to 1188, and the wind is just a gentle cross-shore. That's a big jump in power. This is the best-looking window in the whole forecast. The swell is still a bit short-period at 13 seconds, but that energy is serious.
Wednesday, September 9th, carries that momentum. Morning sees 6ft SSW swell and a gentle cross-shore breeze, energy at 1021. The period is a bit shorter at 11 seconds, but there's still plenty of push. The afternoon holds at 6ft. This is the standout stretch. This isn't for beginners though – anything over 5ft starts getting a bit much, and at 6ft to 6ft, it's getting into intermediate territory. With that short period, it might wall up a bit, but the energy is there.
The rest of the forecast from Thursday, September 10th onward drops back down to marginal 3ft to 3ft SW groundswell with better winds, but nothing that reaches the energy of that Tuesday-Wednesday window.
So, the honest truth: the best bet is to circle Tuesday, September 8th, into Wednesday, September 9th. That's your shot. The morning of the 8th and the morning of the 9th are the pick of the bunch with that big energy and light winds. It's a full week and a half away, so keep an eye on it, but that's the one to point the car towards.
Rusty.

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