The Lowdown

Alright, this is Rusty, coming to you live from the lineup.

We've got a solid block of swell heading our way, but it’s one that’s going to sort the crew from the groms, especially at a spot like Cobblestones. This is a serious reef, advanced only, and it’s gonna be pumping, but the wind is going to be the main character here. We’ll be working with a consistent SSW groundswell for the bulk of the window, but the key is picking the pockets of light wind.

The first few days look good. Wednesday the 22nd is a cracker to start. We’re looking at a solid 12ft SW groundswell with a very long 15-second period, delivering a huge punch of energy (5896). The morning gets a light E breeze, keeping it cross-off and clean. The water’s sitting at 67°, a touch warmer than normal for this time of year, which is a bonus. That afternoon holds up nicely too.

Thursday the 23rd is the standout of this first week. The swell drops slightly to a still-chunky 8ft SW, period still holding at 14 seconds. But the real story is the wind. Thursday afternoon we get glassy, dead-calm conditions with a NNW breeze of just 3 mph. That’s as good as it gets. The lines will be perfect. This is the session to point the car at. The swell is big and powerful, but those glassy conditions are a gift. Expect epic, clean faces on this reef.

Friday the 24th sees the swell back off to around 5-6ft SW, and the energy drops right off (964). It’ll be smaller and less exciting for the experienced crew looking for a challenge.

Saturday the 25th gets ugly. Winds bump up, and by the afternoon we’ve got a fresh cross-shore from the NNW at 22 mph creating lumpy, choppy conditions. Not the one.

Then we hit a big stormy patch. Sunday the 26th is a write-off – strong onshore gales and a massive but messy 16ft swell. That’s a hard pass. Monday the 27th is still messy with a strong cross-shore wind but the swell (10-12ft SW) has plenty of energy.

After the storm passes, look at Tuesday the 28th. We’re back in business with a clean offshore breeze from the NE at 9 mph, grooming that solid 10ft SW groundswell (14-second period). The energy is massive (3457), and the wind is offshore and clean. This is the second true standout of the outlook – a powerful, clean, expert-only day.

The middle of the window (29th-30th July) holds a nice, clean, consistent 7ft+ SW swell with manageable winds, but the quality remains high for the advanced surfer. Keep an eye on Thursday the 30th with a light N breeze and clean 8ft SW swell.

The end of the first week of August looks promising again. Monday the 4th is an absolute sleeper alert – we get a glassy morning with zero wind, grooming a 8ft WSW swell. The period is a very long 17 seconds, which is ideal for a reef like Cobblestones. That long-period energy will draw in some beautiful, heavy lines.

And finally, the very last day of the window, Thursday the 6th of August, throws a massive 18ft WSW swell at us with insane energy (11635), but it comes with a moderate cross-shore. That’s expert territory only, and the conditions will be challenging. There’s a lot of water moving, but it could produce some absolute bombs for the crazy crew.

All in all, this window is for the experienced and the brave. The water’s a touch warm, the swell is consistent, and there are two absolutely perfect days – Thursday the 23rd afternoon and Tuesday the 28th morning – that you don't want to miss. Crowds at Cobblestones can be a factor “sometimes,” but with conditions this demanding and a swell this size, only the die-hards will be out.

Stay safe, read the reef, and get some.

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.
