Alright, Rusty here again, looking at the same Cobblestones forecast, but in feet and Fahrenheit. The water’s about 67°, which is right around the average for now.
We’ve got a solid run of swell starting Monday, July 6th. Waves are 11 to 13 feet from the WSW, with a long 15-second period, pumping a ton of energy (5589 to 6660). The wind is cross-offshore from the SE, so it’s clean. That’s a big wave, so only the advanced crew should be out.
Tuesday morning, July 7th, is the real standout. The swell is 11 feet from the SW, the period stretches to 16 seconds, and the energy is 6430. The wind is almost nothing from the ESE, making it clean. This is the best it gets. The afternoon is a bit less clean, but that morning is gold.
Wednesday, July 8th, is another top morning. The swell is 11 feet from the WSW, period at 16 seconds, energy at 6221. Wind is light from the NNW. The afternoon goes glassy with a light SW breeze. It’s clean, powerful, and for experts.
Then it goes bad from Thursday, July 9th, through Sunday, July 12th. Onshore winds from the W and SW at 12 to 15 mph ruin the surf. The quality is poor. Sit it out.
There’s a chance on Monday, July 13th, with the swell back at 11 feet, but the wind is onshore or cross-onshore, so it’s messy.
Tuesday, July 14th, is the second big standout. The wind goes offshore from the ENE at 5 mph in the morning, the swell is 11 feet from the SW at 15 seconds, and energy is 4797. The afternoon is glassy. It’s clean and powerful. Experts only.
The week after (July 15th to 19th) is hit or miss. Swell is there, but the wind is up or onshore, so the quality is poor.
Finally, look ahead to Tuesday, July 21st. Offshore wind from the ENE, 11-foot swell from the WSW at 16 seconds, and energy at 5916. It’s a long-range promise, but it looks excellent. The afternoon goes glassy.
So, the best bets are Tuesday, July 7th, and Tuesday, July 14th. Big, clean, and powerful. Crowds can show up sometimes, but the size will keep it light.
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.
