The Lowdown
Alright, Rusty here. Let’s have a look at what’s on offer.
We’re looking at Rockpile for the next 16 days, and I’ll be straight with you – it’s a tough stretch. The consistent swell is there, but it’s coming in with a cross-onshore wind almost the whole time, which keeps things messy. The water temp is about average for the time of year, so nothing unusual there.
The first few days, from Tuesday 4th August right through to Monday 17th August, are mostly a write-off. We’re seeing small, weak swells around 2ft to 2ft, mostly from the SW, with a long period around 15 seconds – that’s groundswell energy, but it’s not helping. The wind is light to gentle, but it’s coming from the WSW, W, or SW, which means cross-on or onshore conditions. The combined energy stays low to moderate (between 131 and 391), and the surf quality is repeatedly described as poor. It’s just not doing anything for a paddle surfer.
The pattern shifts a little around Saturday 15th August. The morning still looks poor, but by Saturday afternoon, the swell bumps up to 3ft from the SW, with a 16-second period. The combined energy jumps to 554 – that’s moderate wave energy. The wind is still a light cross-onshore from the W, but it’s just enough to make it marginal. This is the first time the score edges up to a 1 out of 10. It’s still not great, but it’s the best we get.
The last couple of days, Monday 17th and Tuesday 18th August, drop back down into the poor and marginal range. The wind shifts to a cross-shore from the NW and WNW, which is a bit cleaner, but the swell is back to 2ft to 2ft and the energy is dropping. Nothing to get excited about.
Honestly, this is a lean run. If you’re desperate, the afternoon of Saturday 15th August is the only window where the swell and wind come close to lining up, but it’s still only a marginal call. The long period groundswell might make it a bit better for a reef like Rockpile, but the cross-onshore wind is going to mess up the face. For beginners, 3ft is fine, but the wind won’t help. Mostly, this setup looks more interesting for a kite surfer than a paddle surfer.
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.
