The Lowdown

Alright, Rusty here again. Let's break it down in feet and miles.

We've got a solid run of surf coming up at Cobblestones, but you've gotta pick your moments. This is a serious reef break, advanced only, and it's going to be firing with some proper groundswell. The water temp is sitting at 66°, which is a touch warmer than normal for this time of year, so you might get away with a slightly thinner suit.

The first real window kicks off on Wednesday afternoon, the 29th of July. That's when we see a 7ft SSW groundswell rolling in with a 13-second period. The combined energy is a solid 2306 (moderate-strong), and with a light NE cross-off breeze, it's going to be clean. For the experienced crew, this is a solid entry point.

Thursday the 30th is a bit of a two-faced day. The morning is cloudy with a 6ft SW swell at 14 seconds, but the NNE wind is 12 mph, so it's a bit more wind-affected. The afternoon, however, cleans right up with a clear sky and a lighter N wind at 9 mph. The swell holds at 6ft SW, and the energy bumps up to 2093 (moderate-strong). That afternoon session is the better call.

Now, Friday the 31st of July is where it gets big. The morning brings a 12ft SW groundswell with a 16-second period, energy shooting up to 6213 (strong). But the wind is a cross-shore 19 mph from the NW, making it lumpy. It's big and it's messy. The afternoon is a write-off as the wind swings onshore and the rain comes in. Skip it.

The weekend is a mixed bag. Saturday the 1st of August is messy with onshore wind and a 13ft to 16ft swell. Not good. But Sunday the 2nd of August is a standout. The morning shows a 10ft SW swell at 13 seconds, energy at 3314 (strong), and a clean NE cross-off breeze at 9 mph. The afternoon is even better: glassy conditions with a NNE breeze of just 3 mph, the swell holding at 10ft, and energy at 3409 (strong). This is the best of the early run. Clean, powerful, and consistent. Keep in mind, this is a reef break, so that long-period groundswell will be holding up well here.

After that, things get messy again. From Monday the 3rd of August, the wind shifts onshore and the swell jacks up. By the 4th and 5th, we're looking at 13ft+ swells with strong cross-onshore winds. It's a washing machine. This pattern continues right through the first week of August. The swell peaks massively on the 8th and 9th of August with 21ft to 25ft SW groundswells and energy readings hitting over 24,000 (very strong). At that size, it's not just for experts; it's for the truly brave, and the wind is largely cross-onshore, making it a mess. This setup looks more interesting for kite surfing than paddle surfing.

The window finally opens again on Wednesday the 12th of August. The afternoon session shows a 12ft SW groundswell with a 17-second period (very long period), energy at 7114 (strong), and a gentle cross-onshore breeze. It's still a bit choppy, but the quality of the swell is undeniable. That's a long-range standout, but as always, anything two weeks out is promising but less certain.

The final day of the outlook, Thursday the 13th of August, has a 8ft to 10ft SW swell, but the wind is still cross-onshore, so it's not the cleanest finish.

The Pick: Wednesday afternoon the 29th of July and Sunday the 2nd of August are your best bets. Sunday afternoon is the absolute standout: glassy, clean, a solid 10ft SW groundswell with plenty of energy.

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.
