The Lowdown

G’day, Rusty here.

Alright, look, the next couple of weeks at Cobblestones – a solid reef setup – are gonna be a bit of a mixed bag. We’ve got some serious swell pulsing through, but the wind is going to be the main character for a lot of this run. The water is sitting at 67°, which is a touch warmer than normal for this time of year, so that’s a nice little bonus.

The first few days… honestly, we’re paying our dues. Sunday the 19th and Monday the 20th are pretty average. There’s plenty of swell – around 10ft to 12ft from the SW and WSW – but the wind is onshore or cross-onshore, making things a bit sloppy. The wave energy is pretty high (values between 2000 and 4000), but it’s not doing us any favours with the chop. Tuesday the 21st is similar, with cross-shore winds making it tricky.

Then, we get a window. Wednesday the 22nd is the absolute standout of this whole forecast. You get an 12ft swell from the SW, but the magic is in the wind. We’re talking light, cross-offshore breezes from the East and ESE, which is going to groom that big swell into something special. The period is a long 15 to 16 seconds, meaning groundswell with serious grunt, and the energy is massive (over 5000). This is expert territory for sure – over 8ft, so it’s not for the faint of heart – but for those with the skills, it’s going to be firing. The 8ft swell on Thursday the 23rd and Friday the 24th is still solid, with clean conditions and offshore-to-cross-off winds. The swell drops a bit over the weekend, with 5ft to 6ft waves on Saturday the 25th still looking clean.

We hit a rough patch again from Sunday the 26th onward. The wind picks up and swings onshore, and the swell gets messy. There’s a lot of energy (over 3000) but it’s just not surfable. By the time we get to the end of the month, things get wild. Thursday the 30th and Friday the 31st see a massive swell – 13ft to 18ft – but with gale-force winds and near gale conditions, it’s a no-go. The energy is through the roof (over 15,000), but it’s just too big and blown out. The first week of August looks like a write-off with strong winds and big, messy surf.

So, to sum it up: the clear winner is Wednesday the 22nd of July. That’s your day to be at Cobblestones. It’s big, it’s clean, and it’s for experts only. The 23rd and 24th are also good options if you want something a little less intense. The rest of the window is a struggle, but that one day is worth the wait.

Stay safe out there.

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.
