The Lowdown
Alright, Rusty here. Let’s talk about what’s coming up.
We’ve got a reef break on the cards: Rockpile. It’s an exposed spot that gets the SW swell, and it’s usually pretty consistent. The water is a touch warmer than average for the time of year, sitting at 72°F with an anomaly of 4°F, so it’s notably warmer than what you’d normally expect.
Right off the bat, the first couple of days are a bit of a write-off. Monday the 7th and Tuesday the 8th are showing some swell, but the wind is mostly cross-shore and the overall energy is moderate (around 943 on Monday morning), but the conditions are just marginal. Tuesday afternoon on the 8th does clean up with a cross-offshore breeze and a clean wave state, but the swell is only 3ft. It’s rideable for a beginner-friendly wave, but nothing to get too excited about.
The real standout in this whole 16-day window is shaping up for Thursday the 10th. We’ve got a 3ft swell from the SW, with a long period of 16 seconds, and it’s blowing onshore light from the SW. The energy is moderate (509). The key here is the long period groundswell, which at a reef setup like Rockpile will hold up better than at a beach break. It won’t be big, but the shape should be there.
After that, things get pretty grim. From Friday the 11th right through to the end of the period, we’re looking at mostly poor conditions. The swell drops off and gets smaller, the wind stays onshore or cross-onshore, and the energy stays low, often under 500. There’s a tiny flicker of life on the mornings of the 18th and 20th with some moderate energy (639 and 550 respectively) and even a 19-second period on the 18th, but the wave height is only 2ft and the wind is not your friend. The 21st and 22nd are similar – marginal at best, with small swell and poor wind.
Honestly, if you’re not out on Tuesday afternoon the 8th or early on Thursday the 10th, you’re looking at a long stretch of flat, choppy, or onshore slop. The gap between any decent window is basically the whole second half of the forecast.
So, the best bet? Thursday the 10th – early morning glass-off with a clean, long-period SW swell at Rockpile. It’s small, but it’s the cleanest you’ll get in this run.
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.
