The Lowdown
Alright folks, Rusty here. Let’s see what this stretch of the coast has in store for us. The focus is squarely on The Window, a solid reef break that mainly comes alive with a solid SW groundswell.
The first proper action kicks off this Saturday, August 1st. The morning is a bit messy with a cross-shore wind from the SSW at 15 mph, making conditions a bit lumpy despite a solid 13ft SW swell. Wait for the afternoon though. The wind swings around to the SSE and drops to 9 mph, turning into a clean cross-offshore breeze. That 15ft SW groundswell (15-second period) will be pumping, with massive energy levels (9533). The water is sitting at 67°, which is a touch warmer than normal for this time of year. This is a standout session for experienced surfers, as 15ft is expert territory.
Sunday, August 2nd, stays clean with a lighter NE breeze, but the swell drops to 10ft. Still a solid day, especially the afternoon with that light 6 mph cross-off wind. The long-period groundswell (13 seconds) gives decent shape, but the energy is more moderate (2800).
Monday, August 3rd, sees the swell drop further to 6ft. The morning is clean with a NNE cross-off, but by the afternoon, the wind shifts to the NNW and picks up, making things choppy. Not worth getting wet for.
Tuesday the 4th is a write-off. Strong onshore winds from the W at 15 mph ruin any chance of clean surf on the 10ft+ swell.
The best bet of the entire 16-day run is Wednesday, August 5th. Sure, the wind is a cross-onshore from the WNW, but it's light in the afternoon at just 6 mph. The swell is a huge 16ft from the WSW, with a period of 16 seconds. The energy is monstrous (11188). This is big, powerful, and for experts only. If you've got the skills and the board, the morning session with the 12 mph wind will still have some grunt, but the afternoon will be the cleaner window.
Thursday the 6th and Friday the 7th are no-gos, with strong to fresh winds creating lumpy, messy conditions, even with 13ft to 21ft of swell. Not for surfing.
The weekend of August 8th and 9th sees the swell peak at a massive 25ft, but the wind is a mess. The forecast even notes the swell is too big for this break. Kite surfers might be having a field day, but for paddle surfing, it's a pass.
After a few days of poor conditions, things start to look up again on Thursday, August 13th. A new 13ft SW groundswell (18-second period) arrives with a gentle NNE cross-off wind at 9 mph. The energy is strong (10234), and the conditions are clean. That will be a great morning session for advanced surfers.
The run continues into Friday, August 14th, with a smaller 10ft swell but clean conditions, and Saturday, August 15th, holds a clean 10ft morning session with light NNE winds. Solid, consistent, clean waves for experienced surfers.
The final day, Sunday, August 16th, looks like a washout with onshore winds again.
So, to sum it up: Saturday afternoon, August 1st, is the standout early call for clean, big waves. Wednesday, August 5th, is the big-swell highlight for the brave. And Thursday, August 13th, offers another clean, powerful session later in the period. The Window doesn't lie, but it doesn't let you in easy either.
Stay safe out there.
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.
