The Lowdown
Alright, this is Rusty. Let’s have a look at what’s coming up for Cobblestones.
We’ve got a solid run of swell on the cards, but the wind is going to be a major factor. The water’s sitting at 67°F which is a touch warmer than normal for this time of year, so that’s a nice little bonus.
The first decent call is on the morning of the 24th of July. That’s where things finally come together. We’ve got a 10ft SW groundswell with a 14-second period, and the wind is a clean cross-off from the NNE at 15 mph. That’s going to produce some well-shaped, powerful waves at this reef break. The combined energy is strong at 3124 (moderate wave energy), and it’s only for experienced surfers, so this is a standout. The morning of the 24th is the best on offer. The afternoon stays clean with the same wind but the swell drops to 8ft.
Before that, from the 15th through to the 23rd, it’s a mixed bag. There’s plenty of swell, but the wind is mostly cross-on or onshore, often strong, so the quality is poor. The 22nd of July afternoon shows a massive 15ft SW swell with a 16-second period and a combined energy of 10713 (very strong wave energy), but it’s locked in with onshore wind, so it’s a frustrating one. The 23rd morning has a 13ft SW swell with cross-shore wind, giving it some shape, but it’s still lumpy. The 30th of July morning has a 13ft WSW groundswell with a 17-second period and cross-shore wind, but that’s a long way out and the wind is fresh, so it’s one to watch but not a lock.
The 25th of July sees the swell drop off quickly, with a 4ft SSW swell and a fresh cross-shore wind, so that’s the end of the good run. After that, from the 26th right through to the 29th, it’s mostly onshore and messy, with the 29th getting hammered by near gale-force winds. That stretch is a write-off for surf.
So, to sum it up: the clear winner is the morning of the 24th of July at Cobblestones. That’s your window. The morning of the 23rd and the 30th are worth a look if you’re flexible, but the 24th is the one.

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.
