The Lowdown

Alright folks, Rusty here. Let’s have a look at what’s on the cards for Cobblestones. This is a reef break that takes a south-southwest swell, and it’s a spot for the experienced crew only. The water is sitting at 67.8° which is much warmer than usual for this time of year, a real treat.

Alright, the outlook starts on Thursday, August 6th, but it’s a write-off. We’ve got a solid 13.1ft swell from the west-southwest, but it’s coming with a 22 mph onshore wind. The energy is pumping at 9060 (moderate), but the conditions are just poor. Nothing to get excited about.

Friday the 7th is the same story. The swell sticks around 13.1ft to 14.8ft from the southwest, but the wind is howling from the west at 16–25 mph, cross-onshore and messy. The energy is still high (7932, 7394), but it’s blown out. A real shame.

Saturday the 8th sees the swell jump to a massive 23.0ft from the southwest, with a long 15–16 second period. The energy is huge (20825, 24824). But the wind is a strong 28 mph cross-onshore. The wave comment says wind and tide are favorable, but the swell is too big for this break. Unless you’re a madman, stay on the beach. This is a kite-surfing kind of day if anything.

Sunday the 9th drops back to 14.8ft to 16.4ft, but the wind is still onshore from the west and southwest at 16 mph. The energy is still substantial (12888, 8938), but the surf conditions are poor. No dice.

Monday the 10th is a no-go. The wind is a near-gale from the southwest at 31–34 mph, with a 19.7ft to 21.3ft swell. The energy is huge (8446, 14157), but it’s a complete mess. Blown out.

Tuesday the 11th is another day of massive swell, 26.2ft in the morning with a 17-second period. The energy is astronomical (68411). The wind is strong cross-onshore, and the comment says it’s too big for this break. Even the afternoon, with 21.3ft, it’s still too much. This is for experts only who are looking for a death wish.

Wednesday the 12th, the swell drops to 13.1ft to 14.8ft but the wind is still onshore. The energy is moderate (8593, 7051), but the conditions are poor to marginal. Not a good look.

Now, we start to see a glimmer of hope. Thursday the 13th. The swell holds at 13.1ft from the southwest with a 14–17 second period. The wind drops right off to a light breeze, only 6 mph. The morning is marginal, but the afternoon sees a light cross-onshore with small wind ripples. The energy is 9577 (moderate), and the score is a solid 8. This is the first decent window, but it’s still a bit lumpy. For the experienced surfer, it’s worth a look.

Friday the 14th is the standout. The morning is clean with an 11.5ft swell from the southwest and a 16-second period. The wind is a light cross-offshore from the northeast at 9 mph. The energy is 6148 (moderate). The afternoon is even better: 9.8ft swell, 15-second period, and a light cross-offshore breeze from the north-northeast at 6 mph. The wave comment says “excellent surf conditions for experienced surfers.” The energy is 4079. This is the one. Cobblestones will be firing with clean, long-period groundswell. It’ll be a bit straight for a beach break, but on a reef like this, it’ll be perfect. Expect some power.

Saturday the 15th is still rideable. The swell drops to 7.9ft to 8.2ft from the southwest, with a 15-second period. The wind is a fresh cross-offshore at 19

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.
