Table - best surf conditions forecast for Cobblestones over the next 16 days.
Alright, Rusty here, let's get into it. The main event is a massive pulse of long-period SW groundswell stacking up quickly, but the timing is tricky with the winds. There are a couple of standout windows of clean, powerful surf, but this forecast is mostly for experienced surfers.
The first action kicks off Monday, July 13th at Cobblestones. It's a solid start, but not perfect. We're looking at a 13.1ft SW groundswell with a 16-second period – that's a proper groundswell, meaning really long waits between sets but a ton of energy when they come. The combined swell energy is huge at 7227. The water's a touch warmer than normal at 66.6°, so a degree or so above average. The wind is light cross-onshore, so the surface will have a few bumps. It's manageable for the advanced crew that this reef break demands.
Tuesday, July 14th, is the standout. Clear skies, light NE cross-offshore winds make for clean, smooth faces. The swell drops to a still-sizeable 9.8ft from the SW, with a long 15-second period (4309 combined energy). Conditions are described as excellent for experienced surfers. This is the call for the first week.
From Wednesday the 15th, things get rowdy. Strong northerly winds kick up, keeping the wave quality marginal despite the solid 9.8ft SW swell (4554 combined energy). It's clean but messy due to the wind.
Thursday the 16th sees onshore winds and moderate rain with 11.5ft WSW swell – the quality drops off sharply, making it a tough paddle.
Friday, July 17th, through Sunday, July 19th, is a real mess with strong to gale-force winds and rain showers. The swell peaks Saturday the 18th with a massive 18.0ft WSW swell (26884 combined energy!) but it's accompanied by strong onshore winds. At that size, it's a legit big-wave session for experts only, and the wind is not our friend. For the rest of the first week and into the second week, the onshore winds and stormy conditions dominate, making most days a write-off for good surf.
The second week (from July 20th onward) looks blown out for the most part. There's constant onshore wind and more rain, with solid 9.8ft to 13.1ft SW swells, but the wind is just too strong. A potential bright spot is Saturday, July 25th. We see a brief return of clearer skies and a lighter SW breeze coming onshore with a 9.8ft SW swell (3576 combined energy). It's only "marginal" but it's the best-looking day in that second week.
Overall, if you're an experienced surfer and you want to score, make Tuesday, July 14th your absolute priority. It's a short, sharp window of clean power. The rest is a battle with the wind.

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.
