The Lowdown
What’s up, crew? Rusty here, breaking down the next two weeks for us.
Right now, the only break on the table is Rockpile (reef), and it’s a tough sled. We start Wednesday the 29th of July with some rideable SW groundswell around 4 ft, with a 16-second period – that’s a long, lully groundswell. Feels like decent energy underneath (758 combined energy), but with the wind blowing cross-on from the W at 9 mph, it’ll be choppy. Water temp is a balmy 75°, running more than 5° warmer than usual – that’s very unusual for this time of year.
Thursday the 30th morning lightens up to a 6 mph cross-on breeze, but it’s still only marginal, with waves around 4 ft and a 15-second period (760 energy). By Friday afternoon we’re down to 3 ft, and the quality drops off a cliff.
From Saturday the 1st of August through Sunday the 10th, swell stays tiny – between 1 ft and 3 ft, with energy levels hovering in the low 100s to mid-200s. Most of this stretch is either light onshore or cross-onshore wind, and the surf just doesn’t have any push. Not worth paddling out for unless you’re a beginner wanting to practice pop-ups in ankle-biters.
Heading into the second week, things try to perk up from Tuesday the 11th to Thursday the 13th of August. Swell inches up to around 2 ft to 3 ft, with those long-period swells (16–18 seconds) returning. Energy picks up, hitting 446 on Tuesday afternoon and 408 by Thursday afternoon. But the wind remains cross-on or onshore, so even with good groundswell, the surface is a mess. For a reef, that’s a heartbreaker.
If I had to call a sliver of hope, it’s Thursday the 30th of July morning – the cleanest of a messy bunch. Still, don’t expect much.
Long, quiet run here. It won’t stay flat forever, but right now it’s a waiting game.

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.
