The Lowdown
Alright folks, Rusty here. Let’s have a look at what’s coming our way for the next couple of weeks.
Right now, we’ve got a bit of a wait on our hands. The first few days are a write-off, with onshore winds and messy conditions. We’re looking at a gap of about 3 days with no real surf to recommend. The real action, and the standout of the whole run, kicks off on Wednesday, July 22nd at Cobblestones. This is a reef break, so it’s for the advanced crew. The water is a touch warmer than normal for this time of year at 67°F.
Wednesday, July 22nd is the big one. We’ve got a solid 12 ft swell from the SW with a clean cross-offshore breeze. The wave energy is absolutely pumping (5373), and the period is a long 15 seconds, which will give those waves some serious push. Conditions are described as exceptional for experts. The morning is a bit smaller at 8 ft with a 16-second period, but still clean. This is the best on offer, no question.
Thursday, July 23rd keeps the fun going. The morning has 8 ft SW swell with a clean offshore breeze, and the afternoon turns glassy with 7 ft waves. Excellent conditions for experienced surfers.
The surf hangs around, but it’s not as clean. Friday, July 24th sees the swell drop to 6 ft by the afternoon, with a clean cross-offshore breeze and better conditions. Saturday the 25th gets windy, with a 25 mph wind making a mess of things, so that’s one to skip.
Then we get another window. Monday, July 28th afternoon shapes up with a 8 ft SSW swell and a clean offshore breeze. The week after that, from Tuesday, July 29th through Thursday, July 31st, looks promising. The 30th is a real highlight – 7 ft SW swell with a very long 18-second period, moderate offshore wind, and excellent conditions. The energy is up there (3157).
Now, for the brave souls. Friday, July 31st afternoon and into Saturday, August 1st, the swell gets huge. We’re talking 21 ft on Friday and 28 ft on Saturday from the WSW. The wind is offshore, but at those sizes, this is only for experts. The energy numbers are insane (12518 and 43355). For most of us, it’ll be too big.
Sunday, August 2nd is still big, with 15 ft to 13 ft waves, but the wind is clean. It’s a serious session.
After that, Monday, August 3rd brings rain and strong onshore winds, so the window closes.
Remember, that long-period swell (over 15 seconds) at Cobblestones, being a reef break, will handle that energy beautifully. For a bit of perspective, the combined swell energy (43355) is very strong.
So, your best bets are Wednesday the 22nd and Thursday the 30th. Get out there if you’re good enough.
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.
