The Lowdown
Alright, Rusty here again, same spot, different units. Cobblestones is the only break in the game, a reef that demands respect.
The best surf of the 16-day window is gonna be Tuesday, July 14th. Clear skies, light breeze from the NE at 6 mph, and that’s a cross-offshore wind, so the surface is gonna be like glass. Swell is 10 ft out of the SW, with a period of 15 seconds – that’s long-period groundswell, pure power. The combined energy of all swells directed here is 4309, which is moderate-strong, so you’ll feel it in your chest. This is for experts only – 10 ft on a reef is no joke. Water temp is roughly average for the season.
Tuesday afternoon holds the same quality: 10 ft, period 14 seconds, energy 3777, still that light cross-off breeze. Crowds are noted as “sometimes,” so you might see a few others, but it’s worth it.
Wednesday the 15th is blown out with a strong breeze from the NNE at 25 mph. Thursday and Friday are just as ugly – cross-shore winds, rain, and lumpy seas. The swell stays big, but the wind kills it.
Saturday the 18th is a monster: 20 ft in the morning, 16 ft in the afternoon, but with a W or cross-on wind at 22 mph, it’s a total mess. That’s kite-surfing swell, not paddle. Sunday through Tuesday is more of the same – onshore or cross winds, lumpy, choppy, and poor.
There’s a big gap from Wednesday the 15th until late Thursday the 24th. Friday the 24th of July, morning is clear, gentle breeze from the SW at 9 mph, but it’s onshore. Swell is 8 ft from the WSW, period 14 seconds, energy 4045 – moderate-strong. The afternoon is better: light breeze from the SW at 6 mph, cross-on, but only a light ripple, and the swell is 10 ft. It’s workable.
Saturday the 25th is a dark horse: moderate breeze from the N at 16 mph, cross-off, and the swell is 7 ft from the W, period 13 seconds. Clean face, smaller, more manageable.
Sunday the 26th afternoon brings 10 ft from the SW, period 10 seconds, light cross-on wind. That’s a shorter period, so it’ll be softer.
The standout is Tuesday the 14th – morning and afternoon. Big, clean, and that 15-second groundswell is gonna produce some beautiful lines. Friday the 24th afternoon is the second pick, but not as clean. Beyond that, it’s a waiting game for the wind to play fair.
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.
