Alright, Rusty here, and I’m looking at what’s coming up for us at Cobblestones. It’s a solid reef break, advanced territory, and it’s about to get very interesting.
We’ve got a big run of surf starting Monday, July 6th. The swell is already pumping, with a solid 12 ft to 13 ft of groundswell from the WSW, packing a serious punch with a combined energy of 5587. The water is sitting at 67°, which is about average for this time of year. The wind is a cross-off from the SE, so the morning session is clean but the size is serious. At 12 ft, this is expert-only stuff, and the period is a long 15 seconds, so it’s got that deep ocean energy. The afternoon bumps up to 13 ft, still solid.
Tuesday morning, July 7th, is the first real standout. The swell drops a touch to 12 ft from the SW, but the period stretches to 16 seconds, and we’ve got clear skies with a light ESE breeze at 6 mph. The energy is massive at 6430, and the conditions are described as exceptional for experts. This is clean, powerful, and the kind of day that makes the paddle out worth it.
The stretch from Wednesday, July 8th, through to Monday, July 13th, is where Cobblestones really shines. Wednesday morning, the glass-off is on. Wind is WNW at 3 mph, so it’s glassy, and the swell is 12 ft from the WSW with a 16-second period and energy of 6221. The afternoon is similarly glassy. Thursday morning, the 9th, is a write-off with strong cross-on wind, but we’re back on it Friday and Saturday. Saturday morning, July 11th, sees a jump to 16 ft from the SW, but it’s choppy. Sunday morning, July 12th, is a gem: glassy, with a 12 ft SW swell at 14 seconds, and energy of 5630. That is clean, big, and all for the experts.
The best of the best, though, is Monday, July 13th, through Tuesday, July 14th. Monday morning has a 12 ft SW groundswell, period of 17 seconds, with a light NE cross-off wind. The energy is 6167, and it’s glassy clean. Tuesday morning, July 14th, is the same story: 12 ft SW, 16-second period, light NE offshore wind, energy of 6315. These are the sessions where you feel every pulse of the ocean. The swell is big, but it’s a long-period groundswell, so it’s going to be powerful and lined up, best for the reef.
After the 14th, things get messy. By Wednesday, July 15th, the wind picks up hard from the NNE at 16 mph, and the swell is dropping. It’s still clean, but the energy is fading. From Thursday, July 16th, onward, the wind turns onshore and the swell gets too big. By the 18th and 19th, we’re looking at 25 ft to 20 ft swells with near gale force winds. That’s not surfing, that’s survival. The energy numbers are off the charts—19744 and 15515—but it’s blown out and dangerous. The final days, the 20th and 21st, are still massive and onshore, no good for a paddle.
So, to wrap it up: the standout is Tuesday morning, July 7th, for that first clean, powerful session, and then the whole stretch from Monday, July 13th, to Tuesday morning, July 14th, is the true peak. Glassy, clean, and a solid 12 ft from the SW with a 16-second period. That’s the one. Crowds? Cobblestones is a break that can get busy, so expect company, especially on those perfect days.
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.
