The Lowdown
Alright, let’s talk about The Window. This is a reef break that needs a solid SW groundswell and proper wind, and it’s not for the faint of heart. Water temp is 66°F, about average for this time of year.
First real session is Tuesday, July 28th. Tuesday morning brings a solid 10ft SW swell with a 14-second period, wind from the ESE at 6 mph – that’s offshore, light breeze, and the wave energy is pumping at 3549. It’s clean, powerful, and the kind of morning that makes you forget about work. Tuesday afternoon gets even better: wind shifts to WSW at 3 mph, going glassy, with the swell still a healthy 8ft. The combined energy (3582) is still strong. Experienced surfers only, this is the best of the first week.
Wednesday the 29th is still good, with 8ft to 7ft SW swell, cross-off wind from the NE at 9 mph, and energy from 2823 down to 2219. It’s clean but not as pristine as Tuesday. Thursday the 30th holds similar 6ft SW swell, clean cross-off conditions, and energy around 1800 to 1924 – a solid but smaller day.
Then it gets chaotic. Friday the 31st is a washout: 12ft SW swell but with strong cross-on and onshore winds, energy jumping to 6035 and 6586, and the forecast says poor. Saturday, August 1st looks promising but tricky: a massive 15ft SW swell, energy 7567, but with 9 mph ESE cross-off winds. It’s clean, but that’s big, only for experts, and the comment says marginal due to tide or size. Saturday afternoon drops to 13ft, still heavy, with a light breeze, and it’s exceptional for those who know what they’re doing.
Sunday the 2nd drops to 10ft, but 16 mph NE winds make it cross-off and choppy, energy 3749 – it’s okay but not the main event. Monday the 3rd is ruined by 25 mph NNE winds, dropping to 6ft, energy 1429 - not worth it.
Thursday, August 5th is a standout in the second week: a huge 21ft WSW swell, energy 15564, with 9 mph NW cross-on wind. It’s clean-ish but messy, and the comment says “marginal” – again, this is massive, for experts only. Friday, August 7th hits a peak with 21ft WSW swell, 19-second period, energy 25947, but the wind is 43 mph onshore – blown out, even though the tide and swell look good for the break. The rest of the second week is a mess of gale-force winds, rain, and massive swell, with energy readings over 15000 but no surfable conditions until the very end.
There is a gap from the 8th to the 12th of August with no quality surf, mostly because of extreme wind and swell. The last chance is Wednesday, August 12th: 6ft SSW swell, 19 mph cross-wind, and 12ft later in the day with a short 8-second period – it’s lumpy, not great.
So, the standout is Tuesday, July 28th, without a doubt. That morning session with the 10ft SW groundswell and offshore wind is the one to circle. Saturday, August 1st is a close second for the big wave hunters, if you can handle the size and the crowd. The Window gets busy, so expect company on the good days.

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.
