G’day, Rusty here. The Window is about to get some serious juice, but the winds are gonna keep it interesting. There’s a big run of clean, powerful swell coming, but most of it is for the experienced crew only. Let’s get into it.
Starting Saturday the 4th, there’s a solid 10ft SW groundswell with a long 17-second period, and a fresh 30 km/h NNE cross-offshore wind keeps it clean enough for those who know what they’re doing. The wave energy is very strong (4587). Sunday the 5th is a washout with moderate rain and messy cross-onshore breezes—skip it.
Monday the 6th gets real. The morning brings 12ft of WSW groundswell with a moderate 25 km/h SSE cross-off, keeping the surface clean. The afternoon cranks up to 13ft from the same direction, still clean with a 20 km/h SSE breeze. Energy is very strong (6745 in the afternoon). This is huge, powerful surf—strictly for experts. Tuesday the 7th morning is a standout: 12ft SW groundswell, 16-second period, and a light 10 km/h SE cross-off. Clear skies, clean lines, and very strong energy (5926). If you’ve got the chops, this is your session.
But the real gem of the whole forecast is Wednesday the 8th morning. We’ve got 10ft of WSW groundswell with a very long 17-second period, and the wind is glassy—just 5 km/h from the south, dead calm. This is about as perfect as it gets for an advanced reef wave. The energy is very strong (5647). Water temp is 19°, right about normal for the season, so don’t worry about extra rubber. That long period means the sets will pour in with heaps of power and longer gaps, which is ideal for this spot. Just keep in mind the crowds can pop up here occasionally.
Thursday the 9th and Friday the 10th turn ugly with strong cross-onshore winds and lumpy seas—stay on the beach. Saturday the 11th sees a return to cleaner conditions with 12ft SW swell and a 25 km/h SSE cross-off, but it’s only marginal. By Sunday the 12th, the swell drops to 6ft with a light SE breeze, making for a much more manageable morning for experienced surfers.
Into the second week, Monday the 13th morning is a real highlight: 10ft of SW groundswell with a 16-second period and a light 10 km/h offshore ENE wind. Clean, powerful, and rippable. The afternoon stays clean too with 8ft of SW swell. After that, the midweek turns sloppy with onshores and cross-shore winds, and by Friday the 17th it’s choppy and weak. Saturday the 18th and Sunday the 19th bring back big numbers—up to 16ft—but with onshore winds and short, weak periods (8–10 seconds), that’s more for the kite crew than paddle surfers. Energy is strong (5449 on Saturday arvo), but the conditions are ugly.
Your best bets are Tuesday the 7th morning and Wednesday the 8th morning. Both deliver clean, very strong, long-period SW groundswells with light or glassy winds. If you’ve only got one session in you, make it Wednesday the 8th morning.
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.
