The Lowdown

Listen up, Rusty here. Let’s talk about what’s cooking for Cobblestones.

This is a reef break for the experienced crew only, and it’s about to get a serious hammering. The water is sitting at 67°, which is a touch warmer than normal for this time of year, so you might be okay without the thickest rubber.

The action starts on Wednesday the 22nd of July. We’re looking at a solid 12ft SW groundswell with a 15-second period. The wave energy is absolutely pumping (5896), and with a light ESE cross-off breeze, it’s going to be clean and lined up. This is a proper standout for those who can handle it. Thursday the 23rd keeps the quality high. The swell drops a touch to 8ft, but the wind goes glassy in the afternoon, with a NE offshore in the morning. You’ll be looking at some absolutely perfect, clean walls.

By Friday the 24th, the swell backs off to 6ft, but it’s still clean. The weekend turns a bit messy. Saturday the 25th has a 6ft SW swell but the wind swings and gets messy, especially Saturday afternoon with a fresh cross-shore that’ll chop it up. Sunday the 26th is a write-off for us – a strong onshore wind with 15ft of junk. That’s more of a kite day.

We get a reset on Monday the 27th. The swell is back to 12ft, and the wind is a clean cross-off from the SE. It’s still a bit raw, but it's surfable. Tuesday the 28th is a sneaky good day. Solid 10ft SW swell with a clean NE offshore wind in the morning. It’ll be well overhead and clean.

Wednesday the 29th and Thursday the 30th see the swell drop, but the wind gets gusty, and we get a bit of a lull. Then Friday the 31st of July through Sunday the 2nd of August, the ocean goes absolutely mental. The swell jacks up to 16ft and then 20ft on the 2nd, with extreme energy levels (23175). But the wind is a howling onshore. It’s going to be huge and completely blown out – a real wall of white water.

The next true standout pops up way out there on Tuesday the 4th of August. After all the chaos, the winds drop to glassy and the swell settles to a clean 7ft SW groundswell. It’ll be a welcome relief. The period is 15 seconds, so it’ll be a proper long-period groundswell, which on a reef like this will be thick and powerful. I’d be marking that day.

Then another big pulse comes through on the 5th and 6th of August, but with strong winds, so it’s mostly a washout until the end of the run.

Best bet: The Wednesday the 22nd and Thursday the 23rd are your standouts. Get on it early. The long-range promise on the 4th of August is also a solid call, but it’s a long way out.

Rusty, out.

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.
