The Lowdown
Alright folks, Rusty here. We’ve got a solid block of big swell on the way for Cobblestones, but we gotta wade through some rough conditions first.
Things are looking a bit ugly for the opening weekend. Sunday, the 26th of July, is a write-off. We’re talking a massive 18ft SW swell, but it’s getting hammered by a strong breeze onshore, making for a real mess. Forget about it. That trend continues into Monday, the 27th, with an 12ft SW swell and cross-shore winds, just not a pretty picture.
The real change kicks in on Tuesday, the 28th of July. The swell drops to 10ft from the SW, but the wind goes light offshore from the ENE in the morning, then goes completely glassy in the afternoon. This is classic Cobblestones. The wave energy is strong, and the long 14-second period groundswell will be grooming those lines. The water temp is about average for the time of year. This is a standout for experienced surfers only at that size, but the conditions will be absolutely pristine. Wednesday, the 29th, still offers clean 7ft to 8ft SSW swell with light cross-off winds, keeping it fun.
We then hit a bit of a lull. Thursday, the 30th of July, has clean but smaller 6ft SW swell, and then Friday, the 31st, gets blown out with a strong cross-shore breeze and a messy 8ft to 10ft SW groundswell.
The following week starts with solid, but messy, 13ft SW swell over the first weekend of August. The onshore wind is back, so it’s a bit of a washout. Keep an eye on Monday, the 3rd of August, though. The swell drops to a clean 6ft to 8ft from the SW with glassy conditions in the afternoon.
Now, here’s the big one. As we get into the second week, the energy really ramps up, but it might be too much of a good thing. From Thursday, the 6th of August, the swell climbs rapidly. The Thursday afternoon sees a 26ft WSW swell, and into Friday the 7th, it’s a massive 21ft to 28ft WSW swell with very long 17-18 second periods. The wave energy is off the charts. While the winds are light, the forecast is clear: the swell is predicted to be too big for this break. This is expert-only territory, and even then, it’s a question of whether you can get in. For a few days there, it’ll be a spectacle to watch from the cliff, not to paddle out.
Honestly, for the average surfer, your best bet is locked in on Tuesday the 28th of July. That’s the one that’s firing on all cylinders. For the brave, watch the second week, but it’s a promise of something wild, not a guarantee of a good ride.
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.
