Table - best surf conditions forecast for Cobblestones over the next 16 days.
Alright, folks, Rusty here. Gotta be straight with you – we've only got one spot on the radar for this whole 16-day stretch, and that's Cobblestones. So let's break it down.
The early part of the outlook is a bit of a write-off. Friday and Saturday are looking pretty poor, with a messy cross-onshore wind and choppy conditions. The swell is there, but the quality just isn't. Honestly, you'd be better off waiting.
Now, things start to get interesting around Sunday the 13th. We've got a solid 13ft SW groundswell rolling in with a very long 16-second period. The wave energy is massive, clocking in at 7319. The wind is light, only a slight cross-onshore breeze, so the surface should be okay. This is the first real standout – big, powerful lines for the experienced crew. The water temp is sitting at 66°, which is about average for this time of year.
Monday the 14th is also looking clean. The wind swings around to a light offshore from the NE, giving us clean 12ft SW groundswell. The period is still a solid 15 seconds, with strong energy (4828). This is prime time if you want a more user-friendly day than Sunday's big stuff.
Now, hold onto your boards for Saturday the 19th. The forecast shows a 16ft SW swell (energy 9339) with light offshore winds from the ESE. It's going to be absolutely pumping, but this is strictly for experts – 16ft is a beast. The break will be clean and powerful.
For the rest of the second week, we've got some more clean days with offshore winds, like the 20th and 21st, with solid 7ft+ SW swells and long periods. The wind stays favorable, so expect some rippable walls. The last few days, from the 23rd to the 25th, look like a total mess again with strong onshore winds and rain. Avoid that.
Overall, we've got a few windows of truly epic conditions, and the consistency of Cobblestones is solid. The standout is clearly the 19th, but the 13th and 14th are also going to be rewarding for those who can handle the size.
Rusty out.

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.
