The Lowdown

G’day, Rusty here, and we’ve got a proper mixed bag coming up for Cobblestones. This is a solid reef setup, but you’re gonna need your wits about you—it’s strictly for the advanced crew. The water’s sitting at 66°, which is a touch warmer than normal for this time of year, so you can leave the extra rubber at home.

We kick things off on Wednesday morning, July 29, with a 8.2ft SW swell pushing in at a long 13 seconds. The wind’s a gentle cross-off from the NE, and the wave energy is pumping at 2924—moderate to strong. It’s clean, but the conditions are marginal, so pick your tides carefully. By afternoon, the swell drops a bit to 6.6ft from the SSW, still with that long period, and the wind goes lighter. The energy dips to 2306, but this is excellent for experienced surfers. This afternoon window is a true standout—clean, powerful lines, and you’ll have the place mostly to yourself if you’re lucky.

Thursday, July 30, sees the swell settle at 5.9ft from the SW, still a solid 14-second period. Morning wind is a moderate NNE cross-off at 25 km/h, keeping it clean, but the energy is moderate at 1931. The afternoon clears up with a lighter N breeze, and the energy climbs a bit to 2093. Both sessions are marginal, but there’s enough there for a paddle.

Now, Friday July 31 through to Saturday August 1, things get gnarly. Friday morning the swell jumps to 11.5ft from the SW with a 16-second period, but the wind swings NW at 30 km/h—cross-onshore and lumpy. The energy is massive at 6476, but the surf quality is poor. By afternoon, it’s even worse: 13.1ft, onshore WSW wind at 40 km/h, and the energy hits 7826. This is kite-surfing territory, not paddle. Saturday morning stays big at 13.1ft from the SW, with a moderate S cross-shore at 20 km/h. The energy is still huge at 6882, and the conditions are moderate cross-shore chop. Saturday afternoon sees the swell peak at 14.8ft, same direction, with a 15-second period and an SSE cross-shore. The energy rockets to 9922, and this session gets a decent score—it’s big and challenging, but for the advanced crew, there’s something there if you’re hungry.

Sunday August 2, the swell drops back to 9.8ft from the SW, 13-second period. Morning has a clean cross-off from the NE at 20 km/h, and the energy is 3461. It’s marginal, but the afternoon is where it’s at: light NNE breeze, energy at 3721, and the report calls it excellent for experienced surfers. Another good window.

Monday August 3 is a sleeper. Morning is glassy—5 km/h WSW wind, zero chop. The swell is 6.9ft from the SW at 15 seconds, energy at 1981. This is clean, lined-up, and excellent for the crew who know the reef. Afternoon gets a light cross-on from the south, 7.5ft swell, 16-second period, and the energy climbs to 2957. It’s marginal, but the glassy morning is the real highlight.

Tuesday August 4, the swell jumps again to 11.5ft from the SW, 17-second period—very long period groundswell. Morning wind is light onshore from the west, energy at 7210. This is a big, powerful swell, and it’s marginal at best. Afternoon goes to hell with a 30 km/h onshore SW wind, energy at 5491, poor conditions.

Wednesday August 5 through Thursday August 6 is a write-off. Wednesday has 13.1ft to 11.5ft swells, onshore winds, and energy

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.
