The Lowdown
Alright folks, Rusty here, and I’ve been staring at the charts for our little patch of coast. We’ve got a real mixed bag coming our way, so let’s break it down.
Right now, the water’s sitting at 67°F, which is a touch warmer than average for this time of year, so you might be able to ditch the thickest rubber for a session.
The first real window of opportunity fires up on Sunday afternoon, the 2nd of August. The Window is the spot to be. We’ve got a solid 10-foot SW groundswell rolling in with a 13-second period, packing a good punch of energy (2757). The wind is a light 6 mph NE breeze, making for a clean, cross-off setup. Conditions are excellent for those who know what they’re doing – this is advanced territory, no place for beginners. It’s fairly consistent, but crowds are possible, so get in early.
The rest of the first week is a bit of a write-off, I’m not going to sugarcoat it. Monday through to Friday sees a mix of messy onshore winds and building swell that just gets too big and ugly. The energy levels go through the roof – we’re talking 10,000+ readings – but it’s all blown out and lumpy with onshore winds. By Wednesday the 5th, the swell is 15 feet from the WSW, but the wind is cross-on, leaving it choppy and marginal. Not worth paddling out unless you’re testing gear.
The weekend of the 8th and 9th is a tough call. Saturday the 8th sees a massive 16-foot SW swell with big energy (13,074), but the wind is cross-on and choppy through the morning. The afternoon improves slightly to a cross-shore breeze, but it’s still a rough, messy ocean. Sunday the 9th is a no-go with onshore winds and rain.
Now, here’s where it gets interesting. The second week has some promise, but it’s a long-range call so keep an eye on it. The standout for the whole period is shaping up to be Tuesday the 11th of August. The morning is unreal with a clean 23-foot SW groundswell – that’s a massive 18-second period, very long period groundswell, and the combined energy is a whopping 29,087. The wind is a light 6 mph ENE cross-off, and the sky is clear. The caveat? This is for experts only. At 23 feet, it’s going to be a beast, and the long period will make it jack up fast. This is a day for the brave, and it might be too big even for The Window, so only the most experienced should even consider it.
The following Wednesday morning, the 12th, is another good bet. The swell drops to a still chunky 16 feet from the SSW, but the wind goes glassy – 3 mph offshore from the east. The energy is still high (8,019), and conditions are exceptional for experts. The afternoon sees a lighter 13-foot swell with a light sea breeze, so it’s a bit more manageable.
After that, we get a run of clean, workable surf through the 15th, 16th, and 17th. The swell hangs around the 8-foot to 12-foot mark, mostly from the SW or WSW, with cross-off winds keeping things clean. Saturday the 15th is a proper highlight: an 8-foot SW swell in the morning, only 9 mph ESE cross-off wind, and clean conditions. It’s a much friendlier size, but still for experienced surfers. The energy is moderate (4,334). The afternoon bumps up to 12 feet with the same clean wind, which is a gem.
So, to boil it down: if you’re a strong surfer, Tuesday the 11th is the big one, but it’s a monster. For a more realistic but still excellent session, aim for Saturday the 15th or Sunday the 16th for clean, solid waves. The rest of the time, you’ll be watching from the sand.

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.
