The Lowdown
Alright, let's get into it. This is Rusty, and I'm looking at the next couple of weeks for Cobblestones.
First up, Sunday the 2nd. We’ve got a solid SW groundswell rolling in, around 10 to 12 feet, with a nice long period of 13 seconds. The wind is light and cross-offshore, keeping things clean. This is a proper reef break, so it’s for the advanced crew only. The water temp is sitting about average for this time of year, so nothing wild there. The combined energy is pumping at 3936 to 4156 (moderate to strong), so there’s plenty of push. Sunday afternoon is the call here.
Monday the 3rd sees a drop in size to about 6 feet, but the wind picks up strong, making it a bit of a mess. The period stretches out to 15 seconds, but the wind is just too gnarly. The energy drops to 1455 (moderate), and the conditions are marginal. Give it a miss.
Then we hit a rough patch. From Tuesday the 4th through to Saturday the 8th, the wind is howling onshore or cross-on, and the swell is either too big or too messy. The energy gets huge, hitting 28296 (very strong) on the 8th, but with 40 mph winds, it’s a complete write-off for paddling. This is kite-surf territory, not paddle surfing.
Sunday the 9th and Monday the 10th are still blown out, with strong winds and messy waves. The swell is still massive (18 to 20 feet), but the wind is straight onshore or cross-on. Forget it.
Tuesday the 11th is still a mess, but we start to see the wind easing a bit. Still not worth it.
Now, here’s where it gets interesting. Wednesday the 12th, the wind goes glassy in the morning. We’ve got a 12-foot SW groundswell with a 14-second period, and the energy is 4619 (moderate to strong). This is clean, but it’s a big wave for a reef. For the experts, it’s a solid session.
But the real standout is Thursday the 13th. The morning brings a 12-foot SW groundswell, 16-second period, and a light cross-offshore breeze from the NNE. The combined energy is 7007 (strong). The conditions are described as exceptional for the expert crew. This is the best wave of the first week. The water temp is still average, nothing unusual.
Friday the 14th is also very good, with a 12-foot WSW swell, 15-second period, and light cross-offshore winds. The energy is 5024 (moderate to strong). It’s clean and powerful.
The weekend of the 15th and 16th drops off a bit in size, with 6 to 7-foot swells, but the wind stays light. Nothing special, but fun for the advanced guys.
Now, look ahead to the second week. Sunday the 16th morning, we get a big jump again. A 15-foot WSW groundswell, 16-second period, with light cross-offshore winds. The energy is 10771 (strong to very strong). The conditions are called exceptional for experts. This is a big, powerful swell.
Then Monday the 17th, the swell hits 18 feet with a 15-second period, and the energy is 23872 (very strong). The wind is light and cross-offshore, but at this size, it’s only for the absolute top-tier crew. The forecast says it might be too big even for this break. That’s a promising but less certain call for the long-range.
So, the pick of the fortnight is Thursday the 13th morning. That’s the sweet spot. The Sunday the 16th morning is also a standout, but it’s a bit further out and the size is intense. If you’re an expert, mark your calendar for the 13th.
Rusty, signing off.

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.
