The Lowdown
Alright folks, Rusty here. Let’s get into it.
We’ve got a bit of a waiting game on our hands for Rockpile. This is a consistent reef break that’s great for beginners, and it’s wide open to the south-west swell. The water temp is sitting about average for the time of year, so nothing wild there.
The first bit of wave energy worth paddling out for shows up on Friday, the 31st of July. We’ve got a 4ft south-south-west groundswell rolling in with a long 14-second period, packing a decent punch of energy (617). The catch is the wind is light, but it’s coming from the west, making it a cross-onshore breeze. The surface will have a few ripples, not properly glassy. It’s a marginal call with questionable tide. This is the best the whole outlook has to offer, but it’s not a standout day.
After that, things go flat and quiet. From Friday afternoon all the way through to early August, the swell drops below 3ft and the conditions are poor. The wind stays light, but it’s either onshore or cross-onshore, and the wave state is described as “poor” for every window. You’ll be chasing crumbs. We’re looking at a solid two-week stretch of tiny surf, with heights mostly bouncing between 1ft and 3ft. The energy levels are weak to moderate, dropping into the hundreds.
The only other flicker of life comes on Thursday, the 13th of August, and into the weekend. The swell picks up a little to 3ft from the south-west, with a 16-second period, and the energy comes back up to 391. The wind finally shifts to a cross-shore breeze, which is a better angle for the reef. Still, it’s only rated as marginal, and the wave quality is still poor for the rest of the day. It’s not much to write home about.
Honestly, there’s no true standout session here. The first morning on the 31st of July is the closest we get to a wave, but the wind isn’t perfect. The rest of the 16-day window is a long, flat spell. For a spot that’s normally consistent, this is a rough run. Keep your eye on the longer-range stuff around the 13th, but don’t get your hopes up.
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.
