The Lowdown

Alright, folks, it’s Rusty here, and I’ve been staring at the charts for our local patch. It’s a bit of a mixed bag, but there’s a serious window of opportunity if you’re willing to play the waiting game. The first half of the outlook is pretty grim, but the second half has some serious firepower.

We’re looking at a lot of waiting initially. The first few days are a write-off, with strong winds and messy conditions. Don’t even bother paddling out on Tuesday the 25th or Wednesday the 26th until the afternoon. The real action starts to build from Wednesday, but there’s a big caveat.

The standout session – and the one you should circle on your calendar – is Wednesday morning, the 26th of August at Cobblestones. You’ve got a solid 16 ft swell rolling in from the WSW, with a very long period of 18 seconds. That’s a proper groundswell with some serious energy in the water (14,698). The wind is a gentle cross-shore, which is a huge plus. It’ll be clean and powerful. The downside? That’s a lot of water. At 16 ft, this is strictly for the advanced crew. The tide needs to be right, but the forecast suggests it’s lining up. This is the big one. The water temp is a touch warmer than normal at 66°F.

Now, if that Wednesday morning is too gnarly for you, the next best bet is Sunday morning, the 30th of August. The swell drops to a still-serious 10 ft from the SW, with a 16-second period. The combined energy is still strong (4,833). The wind is light and cross-offshore, making for clean conditions. This is another excellent window for experienced surfers. You’ll get those long, lined-up sets, but again, the size keeps it in the expert zone.

The pattern then turns messy again as we head into the first week of September, with onshore winds and more rain. Don’t get too excited about the big numbers on the 5th and 6th – the wind is going to ruin it.

There’s a glimmer of hope right at the very end of the forecast. Tuesday morning, the 8th of September, and Wednesday morning, the 9th of September, both show clean conditions with light winds and a 10 ft+ SW swell. These are excellent windows for experienced surfers, but it’s a long way out, so keep your fingers crossed that the forecast holds.

So, to sum it up: the first week is a non-starter. The only real standouts are Wednesday morning, 26 August and Sunday morning, 30 August. The rest is a gamble. Cobblestones is a reef, so it handles the big SW swell well, but it’s not for the faint of heart.

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.
