Alright, gather 'round. Rusty here.
It’s been quiet for a bit, but we’ve got a run of solid action shaping up for Cobblestones. This is a reef setup, so it's one for the experienced crew only. The water temp is sitting about average for this time of year, so no surprises there.
The real story starts Tuesday morning, July 7th. We’ve got a serious groundswell pulsing in, 12 ft from the SW with a long 16-second period, mixing with a light 6 mph ESE breeze. The energy is cooking at 6420 (moderate to strong), making for exceptional conditions for those who can handle it. That's the pick of the week. The wind stays cross-off, keeping it clean.
Tuesday afternoon sees the swell drop a touch to 10 ft and the wind swings onshore a bit, making it less appealing. Wednesday looks interesting again though. The morning is blown out with a cross-on wind, but Wednesday afternoon is a real beauty. We’re looking at 12 ft from the WSW, glassy conditions with a light 3 mph NW breeze – dead calm. That’s a standout window for the experts.
Thursday and Friday look less exciting as the swell backs off and the wind gets messy. Saturday morning, July 11th, offers a reprieve with 8 ft SW swell and glassy conditions again under an easterly wind, but it’s not as powerful.
Sunday, July 12th, is a big one. The morning is clean with a 6 mph cross-off breeze and 8 ft SW swell, but the real story is Sunday afternoon. The swell jumps back to 12 ft from the SW with a very long 17-second period, and wave energy is pumping at 8131 (strong). Even with a side-shore wind, the power is undeniable.
Monday, July 13th, keeps that energy going. A clean morning with a 6 mph cross-off, 12 ft SW swell, and 16-second period – magic for the skilled crew.
Things start to get messy from Wednesday, July 15th, with strong winds picking up and the surf turning lumpy and poor through the 16th and 17th. That stretch sees big, windy, onshore slop that’s better left for the kite surfers.
We get a small clean-up on Sunday, July 19th, with glassy conditions and a 6 ft SW swell, but the energy is lower. The forecast then winds down with choppy, cross-onshore winds through the 20th and 21st, before a final very powerful but lumpy pulse on Wednesday, July 22nd at 15 ft and 12023 energy (very strong), though the fresh cross-shore wind will chop it up.
Bottom line: The standout windows are Tuesday and Wednesday (July 7-8) and Sunday afternoon, July 12th, for the real big-wave players. Don’t sleep on Saturday morning, July 11th, either, for a glassy moment. After that, it’s a waiting game.
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.
