The Lowdown
Alright folks, Rusty here. Let’s break it down.
We’ve got a long stretch of solid swell heading our way, but you got to know when to paddle out. This ain't a learner’s week. The water is 66°F, which is a touch warmer than usual for the season.
It kicks off on Tuesday, 28 July, with a 10 ft groundswell out of the SW, running with a 14-second period. At *Cobblestones*, it’s a reef setup, and the light ESE breeze is cross-off, keeping it clean. The wave energy is pumping at 3929, so this is proper heavy. Only for the advanced crew.
Wednesday the 29th drops a bit to 8 ft from the SW, still with a solid 13-second period. The wind turns NE at 9 mph, cross-off, clean. The energy sits at 3068. Still a serious, consistent reef wave for the experienced.
Now the real standout. We ride through a sloppy Friday the 31st with cross-shore wind, but Saturday, 1 August, is the day. The swell is a clean 15 ft from the SW, 14-second period, and the wind is light out of the ESE at 9 mph, cross-off. It’s glassy. The combined energy is 8359 – that’s a lot of ocean moving. The break will be handling it, but this is expert-only territory. It’s the best looking day on the board.
Sunday the 2nd is still solid at 8 ft with a NE breeze, keeping it clean.
Looking way out, and this is a long-range promise, so take it with a grain of salt. Wednesday the 5th of August shows a beast – 18 ft from the WSW with a 17-second period. The wind is light NE at 9 mph, cross-off. The energy reading is a massive 18051. The file does say it might be too big for the break, so it could be a washing machine. Keep it on the radar.
From Thursday the 6th, the wind turns ugly with strong NW and SW gales making a total mess. That’s kite-surfing conditions or a total skip.
The pick of the window: Saturday the 1st of August at *Cobblestones*. Clean, massive, and world-class for the experts.
Rusty out.

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.
