The Lowdown
Alright folks, Rusty here. Let’s have a look at what’s on the table for the next couple of weeks.
First up, we’ve got a solid run of swell for the experienced crew. The water temp is sitting about average for this time of year, so nothing unusual there. The real energy is coming from the southwest, and we’re looking at a big window of surf.
Monday, July 27th kicks off, but it’s a bit of a write-off. The swell is a chunky 12 ft from the SW, but that south wind is blowing 12 mph, creating a cross-chop. The combined energy is high (3887), but it’s messy, and the tide might be a factor. Not for the faint-hearted.
Tuesday, July 28th is where it starts to get interesting. The morning drops to 10 ft from the SW, but the wind swings around to a light ESE breeze at 6 mph, making it clean. This is a genuine standout. The energy is still pumping (3929), and with a 14-second period, these are proper groundswell lines. This is a day for the experienced surfer to get on it.
Wednesday, July 29th is also a good call. The swell eases to 8 ft in the morning, but the wind is clean from the NE. The afternoon is even better with 7 ft from the SSW and a light offshore breeze. Clean conditions all day, with 2306 energy. You’ll be smiling.
Thursday, July 30th stays in the 6 ft range from the SW. The wind is offshore from the north, which is the cleanest condition you can ask for. The energy is dropping a bit (1847), but the quality will be there for those who know the break.
Now, Friday, July 31st through Saturday, August 1st is a wild ride. The swell jumps up to 10 ft and then 16 ft, but the wind is a nightmare. We’re talking 22-28 mph cross-shore and cross-onshore winds. The energy is massive (over 8500), but it’s going to be a total mess. Only for the lunatics or the kite surfers.
Sunday, August 2nd is a solid return to form. The swell is 12 ft easing to 10 ft, but the wind is light and offshore (or glassy). The energy is still high (4764), and the conditions are clean. This is a top pick for the experienced surfer.
Monday, August 3rd delivers a clean 8 ft swell with a gentle offshore breeze. The energy is 2281. It’s a very good, user-friendly day for the advanced crew.
Tuesday, August 4th is another standout. The swell is back up to 10 ft, but the wind is light and offshore. The energy is 4896, and with a 16-second period, the power is on. This is a classic long-range groundswell. The afternoon gets a little onshore, but the morning is the session.
Wednesday, August 5th holds steady at 8 ft from the SW with a 16-second period. The wind is offshore, so it’s clean. The energy is 3142. It’s consistent, but not the absolute peak of the run.
Thursday, August 6th through Saturday, August 8th look huge and dangerous. The swell hits 18 ft, then 23 ft, and even 25 ft. The wind is straight onshore or cross-shore at gale force. The energy is off the charts (over 20,000), but the break is taking a full beating. This is wave energy for the kamikaze only. The wind and tide might be favorable for the break, but the size is just too big for mortal paddling.
Sunday, August 9th is still lumpy, with 15 ft dropping to 12 ft, but the wind is messy and cross-onshore. Not a good bet.
Monday, August 10th sees the swell drop to 12 ft, but the wind is messy again. The energy is still there, but the quality is gone.
Tuesday, August 11th ends the forecast with 12 ft from the SW and a 17-second period, but the wind is onshore and strong. A poor finish.
The Bottom Line: The best windows are the morning of Tuesday, July 28th, and the morning of Tuesday, August 4th. That’s your cleanest, most powerful, and most surfable swell. The conditions will be world-class for the experienced surfer. Watch out for the massive, blown-out stuff starting on July 31st and again from August 6th to 8th. That’s for the kite surfers or the incredibly brave.
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.
