Alright, Rusty here, and let's have a look at what's on offer for The Window over the next couple of weeks.
We’ve got a blank start right now, so forget about paddling out just yet. The surf kicks in from Sunday the 5th of July, but the early conditions are a bit of a write-off with that 5ft SW swell getting hammered by a 22 mph cross-onshore and some moderate rain. Not the way you want to start. The energy is moderate at 823, but the wind just kills it. Later that afternoon, the swell builds to 7ft, but it’s still messy.
Monday the 6th is where things start turning. The swell jumps to a solid 12ft out of the WSW, but it’s the wind shift to a 16 mph cross-offshore from the SE that cleans things up. The ocean has some serious energy now (5163), and the surf is clean but big. This is expert territory – over 8ft, so keep the beginners on the sand. The morning and afternoon both look good.
Come Tuesday the 7th of July morning, and this is where we see a real standout. The swell is still a chunky 12ft from the SW, but the wind drops to a light 6 mph cross-off from the ESE, and we’re looking at clean surf with massive energy (6016). The conditions are excellent, but again, that size means it’s for experienced surfers only. The afternoon eases to 10ft, but the wind goes cross-shore, so the morning is the pick.
Wednesday the 8th is another day for the big-wave crew. The swell holds at 12ft from the WSW, with a very long 17-second period. That’s proper groundswell energy (6363) and with a light cross-off from the NNE, it’s going to be clean and lined up. Best suited for the point and reef, as that long period can make a beach break a bit too straight.
After that run of big surf, things taper down slightly but stay fun. Thursday the 9th and Friday the 10th drop into the 7-10ft range, but the wind turns onshore and it gets lumpy. Not worth a special trip.
Now, Saturday the 11th sees the swell pump back up to 13ft out of the SW – that is serious water moving (5265 in the morning, 6575 in the afternoon). But the wind is cross-shore, so it’s going to be a bit of a wrestling match. Only for the hardcore.
The next absolute standout hits on Sunday the 12th of July. The morning has 12ft of SW swell, light cross-off wind, and clean surf (6431). Then the afternoon gets even better: the swell drops to a clean 12ft, but the period stretches to an incredible 17 seconds with energy at 7101. The wind is a gentle cross-off, and conditions are exceptional. This is the session you wait for.
Monday the 13th is a gem of a different kind. The swell drops to a more manageable 7ft, but the wind on Monday afternoon goes glassy – dead calm from the NNE at 3 mph. That 7ft SW swell with an 18-second period (4030 energy) will be absolutely perfect, clean, and peeling. This is the pick for anyone who wants a serious barrel without the death-drop.
The action keeps going through Tuesday the 14th (10ft, clean, light winds), but from Wednesday the 15th the wind turns nasty again with onshores and rain, messing up the 8ft swell.
We get a bit of a reprieve on Thursday the 16th with 6ft in the morning and clean cross-off wind, but it’s marginal. Friday the 17th through to the end of the window on Monday the 20th of July sees the swell bouncing between 10ft and 12ft, with mostly clean conditions and gentle winds. The standout in that last run is Saturday the 18th morning – 10ft from the SW, clean, and excellent for experienced surfers (3050 energy).
Water temp hangs around average for the time of year – about 67°F in that first session, no major anomaly.
So, if you ask me, the Tuesday morning the 7th and the Sunday afternoon the 12th are your true standouts. The Tuesday is big, clean, and powerful. The Sunday afternoon is the whole package – massive energy, clean, and long-period groundswell. And don’t sleep on that Monday the 13th afternoon, it might be smaller, but glassy conditions with an 18-second period? That’s a dream session.
The crowds at The Window can be an issue sometimes, so for those big days, expect a few other keen locals in the water.
Stay safe, read the conditions, and don’t get greedy.
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.
