The Lowdown

Righto, let’s have a look at what’s coming down the line for the next couple of weeks. It’s all about Cobblestones, a solid reef setup that needs a good SW groundswell and offshore winds to really fire. We’ve got a lot of swell on the cards, but the wind is going to be the big story.

The window kicks off on Sunday the 26th of July, but honestly, I’d give it a miss. There’s a big 16 ft SW swell with moderate energy (7344), but the wind is howling from the WSW at 25 mph, making it a messy, blown-out affair. Not a pretty sight.

Monday the 27th isn’t much better. The swell drops to 12 ft, but it’s a cross-shore wind that’s got a chop on it. You’d be fighting a bumpy surface for not a lot of joy. Still, the energy is there (3887).

Now, Tuesday the 28th. That’s where things start to look up. We get a gentle offshore breeze from the ENE, and the swell is still a meaty 10 ft from the SW with a 14-second period. The wave energy is solid (3929). This is clean, powerful surf for experienced surfers only—anything over 8 ft and it’s not for beginners. That 14-second period means quality, long lines. This is your first standout.

Wednesday the 29th holds. The swell drops a touch to 8 ft, but it’s still clean with a cross-off wind. The afternoon session on Wednesday looks even better with 7 ft and clean conditions. Good, fun waves for the crew that knows the reef.

Thursday the 30th and Friday the 31st? The wind turns nasty again. Friday is a total loss with rain and strong onshore winds hitting an 12 ft swell. Just stay on the beach.

Saturday the 1st of August and Sunday the 2nd are interesting. Saturday sees a 13 ft SW swell with moderate energy (7322), but the cross-shore wind will make it lumpy. Sunday the 2nd, though… That’s the second big standout. We get that magic combination: clear skies, a light offshore breeze from the NE, and a 10 ft SW groundswell with a 14-second interval. The wave energy is pumping (5376). It’s going to be clean, powerful, and lined up. This is your target. Pure class for the experienced surfer.

The first week of August has a few more solid days, but the wind is the joker. The 6th of August Thursday morning is a cracker: 15 ft of SW swell, very long 15-second periods, and a light offshore wind with a combined energy of 8830. That is a lot of water moving, and it will be clean. Only for the brave.

After that, it gets wild again. The 8th and 9th of August are blown out by strong westerly winds, and the swell is too messy to recommend.

Overall, the best bets are Tuesday the 28th of July morning and Sunday the 2nd of August morning. Both are clean, powerful, and offer proper reef waves. Crowds are possible at Cobblestones, so get there early. Water temp is a touch warmer than normal for this time of year at 67°F.

That’s the story. Stay safe out there.

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.
