The Lowdown
Alright folks, Rusty here. Let’s have a look at what’s cooking.
We’ve got a slow start, but don’t write the week off just yet. The real action kicks in on Wednesday the 22nd and it’s a ripper. That Wednesday morning, Cobblestones is absolutely pumping. We’re looking at a solid 12 ft of SW groundswell, with a period of 15 seconds, giving it serious energy (5896). The wind is light and cross-offshore, so the faces will be clean and lined up. This is proper, expert-level reef break territory. If you’ve got the skills, this is your window.
Wednesday afternoon holds strong too, with the same size swell and only a slight shift in wind, still clean. Thursday the 23rd is also excellent. The wind shifts to a true offshore from the NE in the morning, with 8 ft of SW swell and a 14-second period (2934). The afternoon glass-off with N wind is a bonus, dropping to 8 ft but still super clean. That’s two days of top-tier waves.
The water temp is about average for this time of year, so a spring suit should be fine.
Now, Friday the 24th through the weekend sees the swell drop off. Friday morning has 5 ft of SW swell (871), but it’s clean with cross-off winds. Not a standout, but a fun size for a session. Saturday and Sunday are smaller and a bit messier, with stronger winds making it less appealing.
Heads up: Sunday the 26th gets nasty. A big 15 ft to 13 ft SW swell rolls in, but it’s accompanied by howling cross-shore winds. The energy is huge (9103 to 12471), but the conditions are a write-off for paddle surfing. That setup is more for the kite crew.
Monday the 27th is a no-go with onshore winds and big, messy swell. We get a bit of a reprieve on Tuesday the 28th, with 10 ft of SSW swell and light winds, giving clean conditions again for experienced surfers. But the following days are a mixed bag of smaller swells and building winds, with a few poor days around the 30th and 31st due to storms and strong cross-onshore winds.
The best of the whole run is clearly Wednesday the 22nd through Thursday the 23rd. That’s the highlight. After that, the second week is patchy. The 28th of July is worth a look for the brave, but the long-range stuff around the 2nd of August has a 16 ft monster arriving with onshore winds, so that’s only for the die-hards or the kites. The setup at Cobblestones for the first week is the clear winner.
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.
