The Lowdown
Alright folks, Rusty here. Let’s have a look at what’s lined up for us over the next couple of weeks.
Right off the bat, we’ve got a bit of a lull. There’s nothing worth paddling out for until the afternoon of Friday, 24 July. From there, things pick up and stay busy for a solid run, but the quality varies.
Friday afternoon, 24 July, is a solid start. The swell is 5 ft from the SW, with a 12-second period. The wind is a cross-off at 9 mph, and the water is sitting at 66°, which is a touch warmer than average for this time of year. It’s clean, and the combined swell energy is moderate at 896. It’s a reef break for advanced surfers only, and crowds happen sometimes.
The real standout window, though, is the morning of Tuesday, 28 July. We have a 10 ft SW swell with a 14-second period – proper long-period groundswell coming in. The wind is offshore from the ENE at 9 mph, making it glassy and clean. The combined energy is very strong at 3726. This is for experienced surfers only. The reef setup here loves a solid SW, so the direction is spot-on. This is easily the best early option.
Moving into the next week, the morning of Saturday, 1 August, is another absolute beauty. We’ve got an 12 ft SW swell with a 17-second period – that’s very long-period groundswell. With a light cross-off breeze from the NE at 6 mph, it’ll be clean. The combined energy is massive at 7478. It’s a real big-wave day for experts, and the direction matches what this break loves. That’s your headline session.
Later on, from around 4 August, the swell builds to serious size – 21 ft to 28 ft – but it’s all onshore or cross-onshore, and some of that energy is just too big for this reef setup. A lot of that period is a write-off for safe surfing. There’s a chance on the morning of Thursday, 6 August, if you’re a serious charger, but the wind and chop make it a tough call.
So in short: Tuesday 28 July morning and Saturday 1 August morning are your golden tickets. The rest has plenty of waves, but you’ve got to pick your windows.
Rusty.

Information about the Cobblestones Surf forecast
The above surf forecast table for Cobblestones provides essential information for determining whether the surfing conditions will be good over the next 16 days. A general guide to surfing at Cobblestones can be found by selecting the local surf guide option on the grey menu. Our Cobblestones 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 (Cobblestones) 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 Cobblestones 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.
Cobblestones is 85 km (53 miles) from the city of Bunbury. If you plan a holiday in Margaret River, look for hotels and other accommodation in Bunbury. Bunbury has rooms for a wide range of budgets as well as car hire and transport links.
