The Lowdown
Alright, Rusty here, and let me tell you about the next couple of weeks at The Window – it’s a bit of a mixed bag, but we’ve got one truly world-class window of opportunity if you're an experienced surfer.
To start, the first week is a write-off for getting a good wave. Saturday the 25th kicks off with 6 ft of lumpy cross-shore junk (1098 combined energy) and Sunday just gets bigger and messier, with a 37 mph cross-on blowing right across the 16 ft+ swell (6731+ energy). It’s a complete no-go. We do get a cleaner spell from Monday the 27th through Thursday the 30th, with consistent 7-10 ft SW groundswell, but the surf quality remains marginal due to tide or conditions – not worth paddling out for.
The real standout, and easily the best on offer, is Saturday the 8th and Sunday the 9th of August. The forecast shows a massive shot of long-period SW swell hitting The Window (a reef break, advanced only). Saturday morning sees 16 ft, but by Saturday afternoon it’s pumping 18 ft (17,774 combined energy) with a period of 18 seconds. That’s a serious, heavy groundswell with raw power. The wind goes glassy or light offshore (ENE/NNE), meaning this powerful reef break will be absolutely clean and barrelling. This is exceptional surf, but only for experts – anything over 8 ft is expert territory, and 18 ft is a beast. The water temp is sitting around 66°F, which is about average for the time of year.
Sunday morning the 9th stays epic, with 15 ft of WSW swell, a light glassy wind, and those same incredible conditions. If you’re an experienced surfer, that weekend is the one you’ve been waiting for.
Before that, there’s a bit of hope on Tuesday the 5th and Wednesday the 6th for some smaller, cleaner surf, but it gets blown out again after that. The long-range window is the keeper.
Stay salty.
Rusty.

Information about the The Window Surf forecast
The above surf forecast table for The Window provides essential information for determining whether the surfing conditions will be good over the next 16 days. A general guide to surfing at The Window can be found by selecting the local surf guide option on the grey menu. Our The Window 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 (The Window) 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 The Window 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.
The Window is 74 km (46 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.
