Listen, let’s break down what’s in the water. We got some serious size coming through The Window, but the wind’s gonna be the boss.
Friday the 3rd kicks it all off. A long-period SW groundswell pushing 10ft, and the energy is chunky – moderate (3200). Water’s sitting about 67°, right where it should be for this time of year. That Friday morning is the shot: clean cross-off breeze out of the ENE at 6 mph. This is killer for the guys who know what they’re doing, but that size – over 5ft – is for experts only. The swell direction from the SW is right on the money. The afternoon’s smaller but not as clean. Saturday the 4th is still big at 10ft, but that NNE wind at 18 mph will put a chop on it.
Sunday the 5th is a bust. Rain and onshore winds, and the energy drops way off. Monday the 6th roars back. Swell from the WSW builds from 10ft to 13ft through the day. Energy goes through the roof – very strong (6254 and 7989). Wind stays offshore from the ESE at 12-15 mph, so it’s clean but heavy. This is for experts only. Tuesday the 7th is solid with 10-12ft SW swell and light, clean cross-off winds. Great day for the experienced crew if you’re brave.
Wednesday the 8th morning is pure silk. 10ft swell, ENE wind at just 3 mph, glassy as it gets. That is the absolute best window of the stretch. The afternoon turns onshore, so paddle out early.
Thursday the 9th through Friday the 10th are messy with onshore winds and lumpy conditions. Then Saturday the 11th hits us with a mega pulse: 13ft SW groundswell with insane energy (10707). Wind is moderate cross-off from the SSE. This is a beast, for experts only. Sunday the 12th and Monday the 13th drop back to a more manageable 8-10ft with clean winds. Tuesday the 14th brings proper offshore breezes from the ENE at 12 mph, making for clean, lined-up waves at 7-8ft. That’s a good session.
Second week gets touchy. Wednesday the 15th the swell drops to 4ft, and Thursday the 16th the wind screams from the NNE at 28 mph, making a mess. There is a pulse on Friday the 17th with 12ft swell, but the wind is howling onshore from the NW at 22 mph, so it’s blown out. Saturday the 18th is a complete loss with onshore gales and rain.
The clear standouts are Wednesday the 8th morning for that glassy perfection, and Tuesday the 7th and Friday the 3rd morning for the big, clean, expert-level waves. The second week’s a lottery at best.

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.
