The Lowdown
Right then, let's get into what's on the menu. Cobblestones is our only option for the next couple of weeks, and it's a proper heavy-hitter, but it's gonna take some patience.
The coming days are a write-off. Through the end of July and into the start of August, we've got a solid SW groundswell pumping in – we're talking 11 to 16 feet with a long 14 to 16 second period, and the wave energy is way up there (7,600 - 10,621). The problem is, the wind is just all wrong. We've got strong cross-onshore winds from the NW, W, and S, just clawing it up into a lumpy, choppy mess. For any surfer looking at that, it's a hard pass. The water temp is about average for this time of year, nothing unusual there.
First real glimmer of hope comes on Sunday, the 2nd of August. The morning starts with a fresh 11-foot SW swell on a 13-second period, and we get a sweet NE cross-offshore breeze. It's clean. The afternoon cleans up even more with a light N breeze and the swell dropping to a still solid 10 feet. The combined energy is around 3,833 to 4,020 – that's moderate but potential. It's still a big wave (over 8 feet), so this is expert-only territory at a top-tier reef break.
Now, if you're an experienced hand, keep your eye on Monday the 3rd of August. That morning is the standout in this whole outlook. We've got a 7-foot SW groundswell with a long 15-second period, plenty of grunt there (2,001 energy). But the real magic is the wind: glassy. Dead flat, SSW air. It doesn't get much better than clean, glassy surf at a reef break. This is the best on offer. The size is more manageable than the prior days, making it the best window for experienced surfers to get some truly excellent conditions. The afternoon gets a bit choppy, so be on it early.
Things get messy again for the rest of the week. A big pulse moves in around the 4th through the 7th of August, with swells pushing 13 to 20 feet. The wind stays onshore and strong, making it a total mess. By the 7th and 8th of August, the swell gets massive – 20 to 24 feet (22,718 energy). The forecast says the break is simply too big to handle. This is more for kitesurfers than paddlers. That big energy stays on through the 9th but with still poor wind.
We get a bit of a breather in the second week. The wind finally drops a bit on the 12th of August, but we're back to a solid 18-foot, super long-period groundswell (18-19 seconds) with a large 22,028 combined energy. It's too big again for Cobblestones, but the wind is light. The next real chance comes on the morning of Thursday the 13th of August. A 15-foot SW swell rolls in with a 17-second period, and a N cross-offshore breeze cleans it up nicely. The energy is high (12,423), so it's still a solid, powerful wave, but the clean conditions will make it a much better prospect for experts.
Overall, there's only one real standout, and that's the glassy morning on Monday the 3rd of August. Get it while it's clean.

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.
