Alright, Rusty here. Let’s break down the next couple of weeks at Cobblestones. This reef needs a good SSW groundswell to do its thing, and it’s going to get hammered with it. But you gotta watch the wind.
Water temps are around 67°F right now, a hair above the long-term average for this time of the year. Nothing crazy.
The first real highlight is Tuesday morning, 7th July. Clean 12ft SW groundswell, with a long 16-second period. The combined energy is kicking at 6420 (moderate-strong). A light offshore breeze from the ESE is putting a shine on it. These waves are going to be heavy and powerful. This is for experts—at this size and period, it’s not a beginner’s game. Best of the early run.
Wednesday afternoon, 8th July, is another cracker. The swell holds at 12ft from the WSW, 15-second period, and the energy is 5723. The key is the wind is dead calm, glassy. That’s rare for a swell this big. The waves will be pristine but still only for confident, advanced surfers.
The rest of the first week gets messy. Thursday the 9th is trashed with onshore wind. Friday the 10th drops to 5-5ft.
Saturday morning, 11th July, we get a reprieve. Glassy conditions on an 8ft SW swell with a 14-second period. It’s still a bit hefty, but experienced surfers will find clean, fun lines. Sunday morning, 12th July, looks solid—10ft at 14 seconds from the SW, energy at 4571, and a clean cross-off breeze. That’s a good session.
Into the second week, the swell stays big. Monday morning, 13th July, offers another clean 12ft SW groundswell, 6368 energy, and a light offshore. Same quality as the Tuesday before.
But then it gets wild. Around the 16th and 17th of July, the swell jumps big. Thursday the 16th sees 15ft WSW at 17 seconds with an energy of 11694, but the wind is howling onshore. It becomes a total mess—too big and too windy for paddle surfing. This looks way more interesting for kite surfing. That onshore mess carries through the 17th, 18th, and 19th with 8-16ft swell and strong wind. Not a surfer’s paradise.
We might get a break on Wednesday morning, 22nd July. The swell drops to 8ft from the SW with a 14-second period, and a light, cross-onshore breeze returns. Not perfect, but a lot friendlier. It’s a long way out, though.
Standout pick: Tuesday morning, 7th July, at Cobblestones. That’s the one.

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.
