The Lowdown

Alright, Rusty here. Let’s cut through the noise and get into what’s happening for us at Cobblestones.

We’ve got a solid 16-day window ahead, but it’s a real mixed bag. The first few days are a write-off – there's some serious swell energy coming in, but the wind is just wrecking it. Hang tight, because there are a couple of proper windows where it all lines up.

The water is sitting at 66°F today, which is a touch warmer than normal for this time of year. That’s a nice bonus for when we do get out.

First up, we’ve got to suffer through Monday the 24th. There’s a 8ft SW swell pushing in, but with a cross-shore wind it’s just messy. Combined energy is way up there at 2492 but it’s not doing us any favours. Tuesday the 25th is even worse – the swell jumps to 10ft and the wind howls from the NW at 25 mph. It’s a total washout, with poor conditions all day. Don't even bother.

Wednesday the 26th sees the swell absolutely jack up to 16ft. It’s too big for most, and while the wind is a bit better, this is strictly for the experienced crew. The combined energy is massive at 15512 – that’s raw power. But really, unless you’re a serious charger on a big wave board, sit this one out. The conditions are described as marginal. Thursday the 27th drops a bit to 13ft, but the wind is still a problem, making things lumpy.

Now, here’s where it gets interesting. Saturday the 29th is the standout. We’re looking at a clean, 7ft swell from the SW with a long period of 16 seconds. That’s proper groundswell. The wind is a light cross-offshore from the SE, which will clean it right up. This is excellent for experienced surfers – the energy is strong at 3804, and the shape on a reef like Cobblestones should be fantastic. This is the call for the whole window.

Sunday the 30th is another solid option. The swell holds at 12ft from the WSW, and the morning has a light cross-offshore wind from the N, keeping it clean. Combined energy is still pumping at 5921. The afternoon gets a bit more cross-shore, but the morning session is prime.

After that, the following week gets tricky. Monday the 31st through to the end of the first week and into the second sees the swell bouncing around 8ft to 12ft, but the wind is inconsistent – onshore, cross-on, and choppy a lot of the time. There are glimmers, like Wednesday the 2nd of September with a light 6ft swell and a slight wind ripple, or Saturday the 5th with a 13ft SW swell that might have some clean windows with a cross-offshore wind on the 6th. But nothing hits the same quality as that Saturday the 29th. The second week is a waiting game, with the combined energy staying moderate to strong, but the wind just won’t play ball consistently.

The Takeaway: Forget the first few days. Your golden window is the morning of Saturday the 29th and then the morning of Sunday the 30th. That Saturday morning surf at Cobblestones with the 7ft SW groundswell and clean offshore wind is the one to circle on the calendar.

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.
