Table - best surf conditions forecast for Cobblestones over the next 16 days.
The Lowdown
Alright folks, Rusty here. Let’s have a look at what’s going on for the next couple of weeks.
We’re looking at a solid run of swell, but it’s not all clean sailing. The first few days are a write-off, with strong winds and lumpy conditions. The real window opens up from Tuesday, 28 July (that’s this coming Tuesday) and runs through to Monday, 3 August, with a couple of standout windows. The water is sitting at 67°F which is a touch warmer than normal for this time of year, so that’s a nice bonus.
Standout Session: Tuesday, 28 July – Cobblestones (reef)
This is the day to circle. Tuesday morning you’ve got a clean 10ft SW groundswell with a 14-second period (moderate wave energy around 3929) and a light offshore breeze from the ENE – that’s going to be glassy, lined-up reef waves. The afternoon goes even better: glassy conditions, 10ft from the SW, and that same long period. This is advanced territory, no question – 10ft is pushing expert level, but the quality is excellent. Crowds are possible here, so get in early.
Thursday, 30 July is another decent option, with 6ft SW swell and a clean cross-offshore breeze, but it’s a step down in size and energy. Consistent, but not as punchy.
The big one: 9 August (Sunday) – A word of caution
We’ve got a massive 26ft to 28ft SW groundswell rolling in on Sunday, 9 August, with a very long period of 16 seconds. The combined energy is off the charts (over 36,000). That’s not just big – that’s insane. This is strictly for elite, experienced surfers only, and even then, the wind is howling onshore at 37-43 mph. It’s going to be a foamy, dangerous mess. This spot is a reef, so the long period will make it powerful, but the wind will ruin any chance of a rideable face. Honestly, this setup looks more interesting for kitesurfing than paddle surfing.
The gap in the middle
After the 3 August, we get a bit of a lull. From 4 August through to 7 August, conditions are messy or blown out, with the swell getting too big again. The next clean window is on Friday, 7 August morning, with a 12ft SW swell and a light offshore breeze – that’s a good one, but it’s a week away, so keep an eye on the forecast.
Best bet: Tuesday, 28 July morning. Clean, powerful, and glassy. Don’t sleep on it.
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.
