The Lowdown
Alright folks, Rusty here. Let’s get into it.
The only game in town for the next 16 days is The Window, a reef setup for advanced surfers. We’ve got a big run of swell coming, but the wind is going to be a real battle for most of it. The water temp is sitting at 66°F, which is about average for this time of year, nothing to write home about.
We start off on Friday the 24th with a bit of a mixed bag. Morning sees a 5ft SW swell with a 12-second period, but the wind is a cross-off from the NNE at 12 mph. It’s clean, but the energy is only moderate (859). The afternoon cleans up a bit with lighter breezes, but the swell is still just okay. Not a standout, but a session to be had.
Saturday the 25th is a write-off. The wind howls from the north at 16 mph, and the swell drops and gets messy. Sunday the 26th is a hard no – onshore gales up to 31 mph and a huge, short-period 12ft to 16ft swell that’s just a washing machine. The energy is massive (2322 to 7203), but it’s all wind and chop.
Monday the 27th is still messy with cross-shore winds and a big, lumpy 13ft SW swell. The energy is still strong (5549), but it’s not surfable for fun.
Now, here’s the first real standout. Tuesday the 28th. The wind goes offshore from the ENE at 9 mph in the morning, and we’ve got a solid 10ft SW groundswell with a 14-second period. That’s a long period, meaning proper energy and better-shaped waves for this reef. The energy is very strong (3302). The afternoon is lighter winds with an 8ft swell. This is for experienced surfers only – at 10ft, it’s well into expert territory. This is the best session of the first week.
Wednesday the 29th keeps the goods coming. An 8ft SW swell with a very long 17-second period in the morning. The wind is a light cross-off from the NE. That’s a groundswell with serious pull. The afternoon is a bit smaller at 8ft but still clean. The energy is massive (4588). This is a close second, but the wind is slightly less perfect than Tuesday.
Thursday the 30th is glassy offshore in the morning with a 6ft SW swell. Clean, but the swell drops a bit. The afternoon gets a side-shore breeze.
Friday the 31st has a big 10ft to 13ft SW swell rolling in, with long periods of 16 to 17 seconds. The morning is clean with a cross-off breeze, but the afternoon gets a cross-onshore. The energy is enormous (5363 to 8931). Still for experts.
Saturday the 1st of August is a special mention. The morning is glassy – absolute mirror conditions – with a 10ft SW groundswell at 16 seconds. The energy is huge (4645). This is as good as it gets for a clean, big wave day. The afternoon gets a bit onshore, so hit the dawn session.
Sunday the 2nd is back to clean cross-off winds with a 8ft to 7ft SW swell. Still good, but not the standout.
Monday the 3rd of August is the biggest standout of the whole outlook. We’ve got an 18ft W swell hitting in the morning, with a 13-second period. The wind is a gentle cross-breeze, and the energy is extreme (12045). The afternoon sees a 16ft W swell with a 14-second period and a clean cross-off breeze. This is the biggest, most powerful swell of the run. The energy is off the charts. For experts only – this is a serious, heavy day at The Window.
Then the wheels come off. Tuesday the 4th brings near gale-force winds, and the swell gets messy. From Wednesday the 5th all the way through to Saturday the 8th, it’s a total write-off. Onshore gales, rain, and stormy conditions. The swell is still there, but it’s blown out and dangerous. You’d be better off on a kite.
So, the pick of the period: Tuesday the 28th for the first clean offshore day with a solid 10ft SW groundswell, and Monday the 3rd of August if you’re an expert looking for a massive, clean W swell. The glassy morning on Saturday the 1st is also a beauty.
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.
