Right, mate, Rusty here. Let's have a look at what's coming up for The Window.
The first few days are a bit of a write-off, honestly. We've got a solid swell rolling in from the 7th of July, but the wind's all wrong – cross-on and messy – so it's not really a paddling proposition. The water temp is sitting at 67°, which is pretty average for the time of year.
Things start to turn around on Thursday the 10th of July. We get a proper window of opportunity. Friday morning the 11th is looking good too, with a 7ft SW swell, a solid 13-second period, and some clean conditions under light offshore winds. The energy's moderate at 1456, and the break's fairly consistent, so you can expect a few sets.
But the standout, the one that's got me a little excited, is Sunday the 12th. You've got a clean 8ft SW swell with a 14-second period, combined energy of 4373, and glassy, clean conditions in the afternoon. The wind's light and cross-off, so the face should be tidy. That's the best on offer for experienced surfers.
Monday the 13th is another cracker – 10ft SW, 16-second period, glassy conditions in the afternoon. That's proper groundswell, and the energy is very strong at 4954. It's a reef break, so that long period will wrap in nicely, but at this size, you'll want to be comfortable on a bigger wave. Not for the groms.
After that, we hit a patch of poor conditions from Tuesday the 14th onwards. Strong winds, lumpy seas, and for a few days we're looking mainly at cross-on junk. There's a gap through to Sunday the 20th before things clean up again. That Monday the 20th morning has a clean 8ft SW swell with offshore winds – a decent option for the second week, but less certain.
Tuesday the 21st afternoon is worth a mention – glassy conditions with a 8ft SW swell and a 15-second period. Energy's moderate at 2342, and the clean face should make for some fun, lined-up waves.
So, for the real standout: Sunday the 12th of July afternoon, and Monday the 13th of July afternoon. Clean, powerful SW groundswell, light winds, and The Window doing what it does best. Get 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.
