The Lowdown
Alright, Rusty here again, but in feet and miles. Let’s talk Cobblestones.
Water temp is about 66°F, right around normal for this time of year—no surprises.
The standout starts Tuesday, July 14th. Tuesday morning brings a solid 10ft SW groundswell with a 15-second period, plenty of grunt—combined energy at 4309, strong stuff. Wind is a light 9 mph cross-off from the NE, keeping it clean. This one’s for experts only; that’s a lot of water moving. The afternoon holds a similar 10ft with a 14-second period, still clean.
Wednesday the 15th has the same 10ft swell but the period jumps to 17 seconds—very long period groundswell. Wind picks up to 25 mph from the NNE, still cross-off but much stronger. Quality dips.
Thursday the 16th is a complete loss with onshore winds and rain. Choppy and poor.
Friday the 17th drops to 7ft, but cross-shore wind keeps it bumpy and marginal.
Saturday the 18th sees a massive 18ft swell, but strong cross-onshore winds and lumpy conditions. This is kite-surf territory, not paddle.
Sunday the 19th stays big and onshore, poor.
Monday through Thursday the 23rd is just a run of big but choppy, windy days. No good.
Friday, July 24th, starts to clean up. Swell drops to 11-12ft, wind goes light—only 6 mph cross-on. Getting better.
The true highlight is Saturday, July 25th. Both morning and afternoon are glassy—wind is basically zero. Swell is 6ft from the SSW with a 12-second period, clean, lined up. Combined energy around 2264. This is the day to be in the water. Still expert-level due to size, but the conditions will be stunning.
Sunday the 26th shifts to a shorter-period W swell with cross-off wind, quality drops.
Monday the 27th is choppy with short-period lump.
Tuesday the 28th brings back 13ft SW swell, cross-shore, marginal.
And Wednesday, July 29th morning is another one to circle. 13ft SSW swell, 12-second period, clean cross-off wind from the east at just 3 mph. Combined energy at 5167—strong but exceptional for experts. Two weeks out, so consider it a promising forecast, not a guarantee.
Best bets: Tuesday the 14th morning and the entire Saturday the 25th. The 25th with glassy conditions and clean 6ft swell is the gold standard here.
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.
