The Lowdown
Alright, let’s see what’s brewing. The only spot in the game is Cobblestones, a reef break for the advanced crew. The water is 67°F, which is a touch warmer than usual for this time of year, so that’s a small win. But the first few days are a total mess.
This Saturday the 18th and Sunday the 19th are a washout. Saturday morning has a massive 18ft swell from the WSW, but it’s getting hammered by a 25 mph onshore wind, making it pure garbage. The energy is huge (8948), but it’s unsurfable. Sunday drops to 12ft, but the wind is still on it, leaving it marginal. Monday and Tuesday are the same story – messy cross-onshore breezes and marginal conditions with swell around 8ft to 10ft. Not worth the paddle.
The first real standout is Wednesday the 22nd of July. The morning brings a clean 12ft swell from the SW, with an offshore breeze from the ENE at just 3 mph. The energy is strong (4468), and it’s excellent for seasoned surfers. By the afternoon, it goes completely glassy – zero wind, clean lines, 12ft SW swell. For a reef break with that long period (14 seconds), the waves will have plenty of punch and shape. This is the best window in the whole run. Crowds are possible here, so get in early.
Thursday the 23rd is still solid – an 8ft SW swell with clean conditions thanks to a cross-offshore breeze. It’s not as powerful, but still a good session. Friday the 24th is a bit of a dud with cross-shore winds.
Then, buckle up. Sunday the 26th of July is a standout. We’re looking at an 12ft to 13ft SW swell with a very long period of 17 seconds. The energy is insane (7798 to 7903), and the wind is light and cross-offshore, keeping it clean. This is exceptional surf, but it’s for experts only. That size and period will make it a beast at this reef. The early morning is the pick.
The following week is a mixed bag. Monday the 27th is still good with a 10ft SW swell and offshore winds, but the size drops. From Tuesday the 28th onward, it starts to fade, with smaller swells and more wind. There’s a spike on Thursday the 30th of July with a 13ft SW swell, but it’s cross-shore and choppy, so it’s a gamble. The energy is high (8225), but the wind kills the quality.
The last few days into August are small and sloppy, nothing to write home about. The best of the whole run is absolutely Wednesday the 22nd and Sunday the 26th. If you’re a charger, don’t miss the 26th.

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.
