The Lowdown
G’day, Rusty here. We’ve got a proper run of swell building at Cobblestones, but it’s not all smooth sailing. The water’s sitting at 66°, which is a touch warmer than usual for this time of year – nothing wild, just a nice little anomaly.
The first real action kicks off Friday morning, July 24. It’s a bit of a slow starter with a 6ft SW swell, but the cross-off breeze from the NNE keeps things clean. The energy’s moderate (950), and the period is a solid 12 seconds, so there’s some push behind it. Friday afternoon cleans up even more with lighter winds and a 5ft SW swell – still a touch on the small side, but very surfable.
Saturday July 25 holds a similar vibe. Morning brings a 6ft SW swell with a moderate cross-off breeze, and the afternoon drops to 4ft with a longer 13-second period. It’s rideable, but nothing to write home about. The energy is still moderate (1123 and 1001).
Sunday July 26 is a write-off. A strong W wind shift kicks up a messy 13ft to 18ft swell, but it’s onshore and ugly. The energy spikes (2734 to 9277), but the conditions are poor. Don’t even think about it. Monday July 27 is similar – big, choppy, and cross-onshore.
Now, here’s where it gets good. Tuesday July 28 is a standout. The morning sees a 10ft SW swell with a 14-second period, clean offshore winds from the east, and the energy is strong (3545). That’s a proper groundswell, and it’s going to wrap in nicely. The afternoon is even better – glassy conditions, 8ft SW swell, and a 14-second period. This is for experienced surfers only, because 8ft is pushing it for beginners. The crowd factor is “sometimes,” so you might have a few out, but it’s worth it.
Wednesday July 29 is still good but a step down. The 8ft SW swell holds in the morning, but the wind is cross-off. The energy drops a bit (3019), but it’s still clean. Afternoon is similar with a 7ft SW swell.
Thursday July 30 is another gem. Glassy conditions in the morning with a 8ft SW swell, 15-second period, and strong energy (3486). That’s very long-period groundswell, so it’ll be powerful and clean, but it may break a bit straight at the beach – though Cobblestones is a reef, so it should handle it well. Afternoon has a cross-shore breeze, so it’s less perfect.
Then comes Friday July 31 – and this is the big one. The morning is already pumping with an 12ft SW swell, 16-second period, and massive energy (6411). The wind is light and cross-off. The afternoon is the crown jewel: 15ft SW swell, 17-second period, and energy through the roof (10546). That’s very long-period, powerful groundswell. The wind is light and cross-shore. This is expert-only territory. The water will be heavy, and the sets will be long. The crowd factor is “sometimes,” but on a wave this size, you’ll likely have it to yourself if you’re comfortable.
Saturday August 1 still has a solid 10ft SW swell with a 16-second period and glassy conditions in the morning. But the afternoon gets a cross-on breeze, so morning is the call.
Sunday August 2 offers a more manageable 8ft to 7ft SW swell, with clean cross-off winds. A good option for those who found Friday too big.
Monday August 3 is massive again – 20ft in the morning and 15ft in the afternoon, both from the W. The energy is enormous (12796 to 18270). The wind is clean, but the swell is simply too big for this break. Only for the most experienced, and even then, it’s a handful.
From Tuesday August 4 onwards, the forecast gets messy. A strong gale-force wind event moves in, with rain and big onshore swells. Wednesday August 5 through Saturday August 8 is all poor conditions – strong winds, rain, and blown-out surf. The swell size is still there (8ft to 13ft), but the wind is junk. Steer clear.
So, to wrap it up: the best of the best is Friday July 31 afternoon, with a close second on Tuesday July 28. If you’re an expert, the weekend of August 1-2 has some solid options too. The second week turns sour, so don’t hold your breath for anything good after the 4th.
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.
