Alright, let’s get into it. The next couple of weeks are all about The Window, a solid advanced-level reef break. The water temp here is 19°, which is pretty much spot on for this time of year, nothing unusual going on.
Monday afternoon sees the first proper swell hitting – a solid 3.5m (that’s about 12ft) groundswell from the WSW with a very long period of 15 seconds, packing a strong wallop of wave energy (6039). It’s cross-off with a SE breeze, so faces will be clean. This is big, powerful stuff – only for experienced surfers. The long period means the waves will have real push and shape, but at this size it can be a handful. Crowds can show up here sometimes, but with this size it might thin the pack out.
Tuesday morning keeps the energy high with another 3.5m SW groundswell, period 16 seconds, and a light SSE cross-off. Clean again. The energy is off the charts (6014), so expect long, powerful lines. This stretch from Monday afternoon through Tuesday morning is the real standout of the early window – consistent, clean, and strong.
Wednesday morning has 3.5m WSW groundswell with 16 second period, but a Westerly onshore wind. That’ll mess up the face a bit, making it less appealing. The energy is still huge (5715), but the wind is a downer.
Thursday sees the swell start to dip a little – still 3.0m (10ft) from the WSW, but period drops to 14 seconds. Onshore winds in the morning with rain showers, then a messy cross-onshore in the arvo. This is a day for the hardcore only.
Friday morning offers a breather: 2.1m (just under 7ft) SW groundswell, 12 second period, light S cross-off. Cleaner again, and much more manageable. The energy (1327) is moderate. This could be a good session for someone with a bit of experience.
Saturday morning, 6th July, you get a real treat: glassy conditions, 3.0m (10ft) SW groundswell, 14 second period. The energy is strong (2956) and with zero wind, it’ll be like glass. This is for experienced surfers only at this size, but the conditions will be world-class.
The runs of quality surf continue into the following week. Sunday is a bit messy with cross-shore winds and 3.0m swell, but then Monday 13th July returns to form: a massive 3.5m (12ft) SW groundswell, 16 second period, light ESE cross-off and clean. The energy reading is 6469 – huge. This is another standout day for experts.
Tuesday 14th July starts with a light NE cross-off, 3.0m (10ft) SW, 14 seconds, then the afternoon turns glassy again. Two excellent windows back-to-back for the advanced crew.
From Wednesday 15th July into the weekend, it gets gnarly. Strong northerly winds, then storm fronts roll in with huge swell (4.5m, almost 15ft on Friday 17th) and howling onshore winds. This isn’t for surfing – it’s a bomb cyclone setup. The energy readings (8594) are insane, but the wind will shred any quality. This is more kite-surfing territory or just gawking from the cliff.
By Monday 20th July, things start to settle but remain messy. Tuesday 21st July, though, brings hope again: a solid 3.0m (10ft) WSW groundswell, 16 second period, with a clean cross-off SE breeze. The long-range window here is promising but less certain – definitely one to watch as it gets closer.
Overall, The Window delivers some legitimate, heavy, clean surf in the first week, especially Monday afternoon to Tuesday morning, Saturday morning, and then again Monday/Tuesday of the second week. The middle of the second week is a write-off. Experienced surfers only at this spot through this forecast.

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.
