The Lowdown
G’day, Rusty here.
Alright, we’ve got a solid window of surf coming up at Cobblestones, but you’re going to have to be patient. The first few days are a write-off with howling onshore winds and a messy ocean. The good news is the swell sticks around and conditions clean up nicely.
The first real chance to get wet is Wednesday morning, July 22nd. That’s the standout of the whole run. We’re looking at a clean 8ft SW groundswell with a very long 16-second period, and light offshore winds. The combined energy is pumping at 5183, which is strong. This is a proper reef break setup, so that long period will wrap in nicely with good shape and power. For advanced surfers only at that size, but it’ll be worth the wait. Wednesday afternoon holds size at 12ft (5300 energy), still clean, but a little more size and a touch less wind – still a good option for the crew who can handle it.
Thursday the 23rd is another cracker. Thursday morning is the call here: 8ft SW swell with a clean 14-second period, and proper offshore winds from the ENE (12 mph). That’s excellent, experienced surfer territory. Combined energy is strong at 2686. The afternoon goes glassy with a 3 mph cross-off breeze and 8ft SW swell – clean as a whistle.
Friday the 24th drops off a bit to 5ft, but the winds stay favourable (cross-off). The afternoon has “very good” conditions, so if you’re after a more mellow session, that’s your window. The combined energy is weaker in the 800s, so it’s not a powerhouse.
Saturday the 25th gets blown out. Strong winds, messy, big swell but no quality. Skip it. Sunday the 26th is a total no-go: 15ft onshore slop with gale-force winds – that’s kite-surf territory if anything.
Monday the 27th might be rideable for the brave, with 13ft swell but cross-on winds and chop. Tuesday the 28th morning looks cleaner again with 8ft SW and light cross-off winds – a solid backup option for intermediates who want to push it.
Wednesday the 29th keeps the clean theme with 7ft SW and light offshore winds, and Thursday the 30th winds down with 4ft SSW groundswell but clean offshore winds – that’s a fun, smaller end to the run. The weekend of August 1st has a couple of promising windows, but it’s further out, so treat it as a hopeful maybe. Winds stay good, but the swell is inconsistent.
Crowds at Cobblestones can be an issue sometimes, so get there early on the good days, especially Wednesday and Thursday.
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.
