The Lowdown

Alright folks, Rusty here. Let’s have a look at what’s on the table for Cobblestones over the next couple of weeks.

First up, the water temp is sitting at 67°F – a touch warmer than normal for the time of year, so you might get away with a lighter suit.

The first half of the period is a bit of a mixed bag, but we’ve got one absolute standout. The swell is primarily from the SW, and Cobblestones is a consistent reef setup that handles that direction well. It’s an advanced wave, so leave the foamies at home.

The real highlight is Wednesday morning, the 22nd of July. We’ve got 8ft of SW swell, with a solid 15-second period – that’s proper groundswell, packing a heap of energy (5896). The wind is light and cross-offshore from the ESE, which means it’ll be clean. For a reef break, that long period is a dream – it’ll wrap in nicely and hold its shape. This is the one to circle.

The rest of that week ebbs and flows. Thursday the 23rd morning has 8ft SW swell and true offshore winds from the NE, making for some clean, punchy walls. But by Sunday the 26th, forget it – a strong onshore blow from the WSW with 25 mph winds and 13ft of messy swell will have it blown out. That’s a skip day.

We’ve got a decent run from Tuesday the 28th through to Friday the 31st of July. Mid-week looks solid: Tuesday the 28th has 8ft SW swell with offshore ENE winds, clean and powerful. The swell energy is still hefty (3342). By Thursday the 30th, the swell drops to 4ft with a 16-second period, and on the afternoon we get glassy conditions – that’s a rare treat for a clean, small day.

Now, the real firecracker comes on Sunday the 2nd of August. The afternoon sees 13ft of W swell, a 13-second period, and moderate offshore ENE winds. The energy is huge (6232). That’s expert territory, no question. The waves will be big, powerful, and lined up. If you’ve got the skills, that’s your session.

The first few days of August bring a solid pulse of WSW swell, with 18ft on Monday the 3rd and 16ft on the afternoon. The energy readings are massive (13008 and 10753). But the wind is cross-offshore and strong – 25 mph gusts. It’ll be big, raw, and challenging. Only for the brave and the experienced.

The tail end of the outlook, around the 5th of August, still has 13ft+ of SW swell, but the wind stays strong and cross-offshore. The quality is there for the experts, but it’s not a beginner’s game.

Cobblestones is a reef, so it’s not a place you want to take a wrong drop. It’s a consistent spot, but crowds are possible – so get in early for the clean windows.

If you’re looking for the best of the best, lock in Wednesday morning the 22nd of July for perfect conditions, and keep an eye on Sunday the 2nd of August afternoon for the big-swell crew.

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.
