Alright, let’s get into it.
We’ve got a proper stretch of solid, powerful groundswells coming our way over the next couple of weeks, all focused on one spot: Cobblestones. This is an advanced reef break, exposed to the open ocean, and it’s going to be absolutely pumping at times. The water temperature is sitting at 67°, which is pretty average for this time of year, nothin’ out of the ordinary.
The real kicker is Monday the 6th of July. That afternoon we’re looking at a clean 13 ft swell from the WSW, with a long 15-second period pushing through. The combined energy is massive at 6660, and the wind is a nice cross-off from the SE. This is the standout session of the week – proper expert territory. It’s going to be big, powerful, and clean.
Tuesday the 7th sees a tiny drop, still with an 12 ft swell from the SW, but that morning the wind goes cross-shore and it gets a bit lumpy. The real magic returns Wednesday the 8th in the afternoon. The wind goes glassy, dead calm, with an 12 ft SW swell at 15 seconds. That’s a top-tier window for those who can handle the waves. The energy is still well over 6000.
Thursday the 9th gets a bit messy with onshore wind, and the swell backs off through Friday. But don’t sleep on the following Monday, July 13th. Early morning, we get a 13 ft SW groundswell with a 16-second period, clean cross-off from the ESE, and the energy spikes to a massive 7500. That’s about as good as it gets for a serious reef. The wind stays light and off the next morning, too, on Tuesday the 14th.
Now, the second week gets tricky. From the 15th, the wind picks up hard from the NNE, and while the swell stays solid in the 8 ft to 10 ft range, it’s blowing like crazy. By the 16th and 17th, we’ve got strong winds and rain, with 15 ft of onshore junk on Friday the 17th. The 18th turns into a full-blown gale with 37 mph winds. It’s a write-off. The surf is going to be poor, blown out, and dangerous for anyone but the kamikaze crew.
There is a glimmer late in the run, on Monday the 21st of July. The wind swings back to a clean cross-off from the SE, we get an 12 ft WSW swell with a 16-second period, and the energy is back up over 5500. That afternoon could be a sneaky good session on the back half of the swell, but it’s a long way out so don’t book your flights yet.
Overall, the first week and a half has a couple of absolute gems for experienced surfers. The rest is mostly big, windy, and unappealing. Stay sharp and pick your windows.

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.
