The Lowdown
Alright folks, Rusty here. Let's get into it.
First up, we've got The Window. It's a reef break, and it's one that's fairly consistent. The water temp is sitting at about 66°F, which is pretty much what you'd expect for this time of year.
The swell is coming in from the SW, which is the sweet spot for this break. We're looking at a solid 8ft of swell for Wednesday morning, with a period of 13 seconds. That's a nice groundswell, and the combined energy is pumping at 2671. The wind is a cross-off from the NE at 12 mph, and the wave comment says it's clean. This is a solid start and the best we've got on offer for the first few days. Wednesday afternoon, the swell drops a touch to 7ft, the wind lightens up to 6 mph, and it's still clean. This is a really good window for experienced surfers, as the 7ft to 8ft range is a proper size but not out of control.
Thursday morning sees a bit of a bump in the wind, with a 15 mph cross-off from the NNE, and the swell is at 6ft. It's still clean, but the wind is a bit stronger. The afternoon shifts to a cross-shore, which is a little less ideal.
Friday is where things get messy. The swell jumps up to 10ft in the morning, but the wind swings to a cross-on from the NW at 18 mph, and the wave comment calls it poor. The afternoon is even worse, with 12ft swell and onshore wind. This is a full-on stormy setup, more for kite surfers than paddle surfers.
Saturday morning, the swell is a huge 13ft, but the wind is a cross-off from the SSE. The wave comment says it's marginal, but with that size, it's only for the experts. The afternoon gets even bigger at 16ft, and the combined energy hits 10901, which is very strong. It's still a cross-off, but the size is intimidating.
Sunday morning is back to 10ft with a cross-off from the NE, but the real standout is Sunday afternoon. The swell is 10ft, the wind is glassy from the NNE at just 3 mph, and the wave comment says it's excellent for experienced surfers. This is a moment of pure clean power. The only downside is that this spot can get crowded sometimes, so you might have some company.
Monday morning is another glassy moment, with 7ft of swell from the SW and a 15-second period. The glassy wind from the W makes for some of the cleanest conditions you'll see. Monday afternoon, the wind shifts to a cross-on, and the quality drops.
From Tuesday, 4th of August, through to the end of the forecast, it's a long stretch of big, powerful, and mostly messy swells. We're talking 12ft to 20ft swells, with onshore and cross-onshore winds ripping at 15 to 28 mph. The wave comments are consistently "poor" for this period. The 12th of August, Wednesday morning, has a massive 20ft swell with a 17-second period and a clean cross-off wind from the SE, but the wave comment says it's too big for this break. The following days have similar energy levels, but the wind is always a mess. This is a two-week long stretch of heavy, blown-out conditions that are not for the faint of heart.
So, to sum it up: the first few days, especially Wednesday and Sunday afternoon, are your best bets. After that, you're either looking at huge, dangerous surf or a total washout. The second week is a write-off.
Rusty, signing off.

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.
