Table - best surf conditions forecast for Cobblestones over the next 16 days.
Alright, mate, let’s have a look at what Cobblestones is doing. It’s the only spot we’ve got on the cards for the next couple of weeks.
The water’s sitting at 67°, which is dead average for this time of year, so nothing crazy.
The first few days are a bit of a mess, to be honest. Saturday the 11th and Sunday the 12th have some solid 10ft to 12ft SW swell, but the wind is a messy cross-on. The wave energy is moderate to strong (2820 to 6920), but it’s choppy and ugly. Not worth paddling out for.
The real standout is Tuesday the 14th. The swell drops to a very manageable 10ft from the SW, with a nice long period of 14-15 seconds. That’s proper groundswell. The key is the wind. Tuesday morning we’ve got a clean offshore from the NE, and by Tuesday afternoon it goes absolutely glassy with zero wind. For a reef break like this, that’s a dream. The wave energy is still strong (3968 to 4427). This is the best session on offer, hands down. It’s an advanced wave, so leave the beginners on the beach.
We get a bit of a mixed bag mid-week. Wednesday the 15th gets hammered by a fresh 19 mph cross-shore, making it lumpy. Not worth it. Thursday the 16th and Friday the 17th are a write-off with strong winds and poor conditions. The energy is there, but the wind is a killer.
Saturday the 18th is a bit of a beast. The models are showing a massive 20ft SW swell with a very long 17-second period. That’s a huge amount of energy (21793). The problem is the wind is howling onshore at 34 mph, and the swell is honestly too big for this break. This is for experts only, and even then, it’s going to be a wild, dangerous session. I’d call it more of a kite-surfing day if you’re game.
We get a bit of a reprieve on Sunday the 19th with a 13ft SW swell and lighter winds, but it’s still cross-shore. It’s a marginal call.
Looking further out, the week of the 21st has another potential highlight. Tuesday the 21st is glassy again with an 12ft SSW swell. The period is a bit shorter at 11 seconds, but the glassy conditions will make it clean. It’s another one for the experienced crew.
After that, the wind swings around and gets nasty again from the 24th onwards, with strong onshore gales and rain. The swell is still solid, but it’s going to be a choppy mess.
Overall, the best bet is Tuesday the 14th. That’s the one with the cleanest conditions and a solid, long-period swell. The Sunday the 19th is a backup, but it’s not as clean. The later window on the 21st is promising but less certain.

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.
