Table - best surf conditions forecast for The Window over the next 16 days.
Alright, let’s break it down. Swell’s coming from the southwest with some real power, but we gotta pick our moments. The Window is a reef break that’s fairly consistent and open to that SW swell.
Friday the 10th is a dud – cross breeze, messy. So we wait. Saturday the 11th morning, that’s the one. Swell’s at 8ft from the SW, 13-second period – real groundswell. Winds are light from the south, almost offshore, making it clean. The combined energy is strong at 2492, and it’s excellent for experienced surfers. Water temp is about 67°, which is normal for the season. This is the standout: Saturday morning.
Sunday the 12th and Monday the 13th swell bumps up to 12ft, but the wind goes cross-on, and it gets a little choppy. Still surfable for the right people, not as clean. Tuesday the 14th is a gem – morning has a light offshore from the NE, 10ft SW swell, 15-second period, clean. Then Tuesday afternoon goes glassy – no wind. That’s a great session if you can make it.
Then it all goes sideways. From Wednesday the 15th through the weekend, strong onshore winds from the NW and WNW, gusting up to 34 mph, lumpy and blown out. Swell stays big, up to 16ft, combined energy hitting 15037 at one point, but it’s chaos. That stretch is for kite surfers, not paddle surfing.
There’s a few days of poor conditions, then Monday the 20th is still messy. Tuesday the 21st is a no-go. Wednesday the 22nd is average.
But look ahead – Thursday the 23rd morning brings a light offshore from the NE again, 12ft SW swell at 13 seconds, clean. And Friday the 24th morning, light offshore from the NNE, 12ft from the WSW, period 12 seconds, clean. Those are promising, but being over a week out, don’t bet the farm on it yet.
Best on offer: Saturday 11th July morning and Tuesday 14th July morning/afternoon. The Window will be firing and clean both times.

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.
