The Lowdown
Alright folks, Rusty here. Let’s get into it.
Water temps are sitting at 67°F, which is a touch warmer than normal for this time of year. Nice.
The next few days are pretty grim. There’s a big gap with nothing worth paddling out for until Thursday the 23rd. That’s a solid week of waiting. Early on, we’re hammered with onshore winds and messy, oversized swell – Saturday the 18th sees a massive 18ft swell with onshore wind, total write-off unless you’re after some kite surfing chaos. The combined wave energy is absolutely pumping at 10605, but that’s just raw power with zero quality.
The first real glimmer shows up on Wednesday afternoon, the 22nd. Cobblestones will see a 13ft swell from the SW, with a period of 14 seconds. The wind goes cross-offshore from the SE, cleaning it up nicely. The energy is strong at 5672. This is a big, powerful reef wave and still going to be only for the experienced – that size is no joke. One to watch from the cliff.
The standout window opens Thursday the 23rd. That afternoon, Cobblestones cleans right up with offshore wind from the east at 12 mph. Swell is a solid 8ft from the SW with a 13-second period. It’s a classic combo of size and form. The wave energy is 2528, so still plenty of push. This is the best of the bunch. Crowds are a possibility here, so get in early.
Friday the 24th keeps the run going. Morning is clear, light offshore from the ENE at 12 mph. Swell drops a touch to 7ft from the SSW, period at 13 seconds. Clean, lined-up waves for the advanced crew. The afternoon gets even lighter with only 6 mph offshore, and the swell settles to 6ft. That’s the session to slide into.
Saturday the 25th morning is gentle offshore at 9 mph, swell at 5ft from the SW, period 11 seconds. In the afternoon, it picks back up to 7ft from the SW with a very long 15-second period – that groundswell will wrap in nicely here at the reef. Wind is light cross-off from the NE. Clean and lined up.
Sunday the 26th afternoon sees another solid window: 7ft SW swell, 14-second period, and gentle cross-off breeze from the NNE. Clean conditions, great for a reef break like this. The energy is moderate at 2268.
From the 28th onwards, the wind swings onshore again and things get sloppy. A total blank from Monday the 28th through the end of the month. Big cross-on swells and lumpy water mean the board stays in the car.
The clear winner is Thursday the 23rd and Friday the 24th. Clean offshore winds, solid SW groundswell, and the reef doing its thing. Don’t sleep on that window.
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.
