Table - best surf conditions forecast for The Window over the next 16 days.
G’day, Rusty here. Let’s get straight into it. We’ve got one spot on the radar for the next couple of weeks, and it’s The Window, a solid reef break that’s fairly consistent and fairly exposed to the swell. The water’s sitting at 66°, which is pretty much bang on average for this time of year, so no surprises there.
The outlook kicks off Thursday morning, July 9, with a solid 3 yd WSW groundswell running at 14 seconds. That’s a long-period swell, which means proper lines and decent energy between sets, and the combined energy is a hefty 3107 (moderate to strong). The wind is light cross-onshore from the NNW, so it’s not perfect, but it’s workable. The afternoon sees the swell drop a little to 3 yd, but the wind swings SW and picks up to 15 km/h, making it a bit choppy. The score’s low, so don’t expect a classic.
Friday the 10th keeps the swell in the 2 yd to 2 yd range, but the wind is straight cross-shore from the south at 20 km/h, creating a cross-chop. It’s a bit of a battle. Saturday the 11th looks better in the morning: 3 yd SW groundswell, period 13 seconds, and light southerly cross-shore winds at 10 km/h. The combined energy is 2176 (moderate). It’s not glassy, but it’s clean enough to get a few. The afternoon swells back up to 3 yd, but the wind picks up and turns cross-shore again, so it’s a mixed bag.
Sunday the 12th offers a good 3 yd SW swell with a 14-second period, combined energy at 4479 (strong). The wind is light cross-onshore in the morning, just a slight ripple. That’s a solid day if you’re keen on a bigger wave. The afternoon sees the swell drop to 3 yd, but the wind freshens.
Now, Monday the 13th is a standout. We’ve got a 4 yd SW groundswell with a very long 16-second period, combined energy of 6603 (strong to very strong). The wind is light cross-shore from the SSW at 10 km/h, keeping it clean. This is a big, powerful swell, and with that period, it’s going to offer some deep, fast barrels at The Window. It’s only for experienced surfers—over 3 yd is expert territory, so don’t even think about it if you’re not solid. The afternoon holds similar conditions.
But the real gem is Tuesday the 14th. Morning brings a 3 yd SW groundswell, 15-second period, and the wind turns cross-offshore from the ENE at 10 km/h, with clean conditions. The combined energy is 4178 (strong). The afternoon is even better: wind goes offshore at just 5 km/h from the ENE, glassy, and the swell holds at 3 yd with a 14-second period. This is the best of the window. Crowds are possible here—it’s a break that can get busy, but with the size and quality, it’ll be worth the paddle. The offshore wind and that groundswell energy will make for some epic, clean walls.
Wednesday the 15th drops off a bit to 3 yd, with light cross-onshore winds, and the surf holds through the week. From Thursday the 16th to Sunday the 19th, the swell bounces between 3 yd and 4 yd, but the wind deteriorates. Strong cross-onshore and even onshore winds, especially on the 18th with 40 km/h winds, will make it messy and blown out. That’s a write-off, likely better for kiting than paddling.
Monday the 20th brings a nice reset: 3 yd SW swell, light cross-offshore NNE wind at 5 km/h, and clean conditions. The combined energy is 1749 (moderate). It’s a bit smaller, but the clean wind and consistent swell make it a solid session. Tuesday the 21st holds similar size but with a 15-second period, combined energy 2309 (moderate), and cross-offshore NE wind at 20 km/h, keeping it clean again.
After that, the wind turns ugly from the 22nd with onshore and strong cross-offshore winds, and the swell drops. The 24th offers a small 2 yd SW swell with clean cross-offshore wind, but the energy is low (1360, weak to moderate).
Overall, the best is Tuesday the 14th—that offshore wind, 3 yd groundswell, and clean conditions are a proper standout. Monday the 13th is a close second for the sheer power, but it’s expert-only. The rest of the run is a mix of solid waves and windy chaos, so pick your windows wisely.
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.
