The Lowdown
Hey folks, Rusty here. Let's talk about the home break, Rockpile, over the next couple of weeks.
To be straight with you, the outlook is pretty grim for a while. The surf is small and the wind is messy. The water is sitting at 72°, which is a touch warmer than normal for this time of year, so at least it’ll feel nice on the skin.
Wednesday the 9th has a tiny 2ft SW groundswell with a 16-second period, giving us moderate energy (397). The wind is a light cross-shore from the WNW, so it’s not blown out, but the wave comment says it’s marginal. Honestly, it’s a skunk session unless you’re on a log.
Thursday the 10th morning looks a little better on paper with a 3ft SW swell, same long period, and stronger energy (513). The issue is the wind is straight onshore from the SSW at 9 mph, and the report says marginal. By afternoon the wind goes cross-on and it’s a no-go.
Friday the 11th through Sunday the 14th is a write-off. The wind is onshore or cross-on from the south and southwest, with chop. The swell drops right off, and the energy dips into the 200s. You’re better off staying home.
Now, from Monday the 15th onwards, things start to get a little more interesting, but it’s still far from firing. The swell stays small, 1ft to 3ft, but the period is long and the energy builds back up. Tuesday the 15th afternoon has a 1ft, 20-second swell from the SSW – that’s a very long period groundswell. The energy is only moderate (309), and the wind is light cross-on. It’s marginal, but for a patient surfer on a point break or reef, those long lines could offer a few sneaky ones.
The best bet in this whole 16-day window looks to be Saturday the 19th. The morning has a 3ft SW swell with an 18-second period, and the energy is a decent 568. The wind is light from the WNW, so it’s a light cross-on breeze. The afternoon has a bit of cloud cover but the wind swings light from the south, still cross-on. It’s still marginal, but this is the cleanest window we get. The swell is small, but the long period means it’ll have some shape. Saturday the 19th is the standout, but keep your expectations in check. It’s a spot that’s consistent, so it tends not to stay this poor for long.
The rest of the period into the 24th is a mix of marginal and poor conditions with onshore winds and small swell. Nothing to get excited about.
This is Rusty, signing off.

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.
