The Lowdown
Alright, Rusty here again, this time in feet and miles. We’re talkin’ about The Window, a reef that’s strictly for the advanced crew. Water’s around 66°, pretty much normal for this time of year.
The first few days are a bit of a slow burn. Thursday the 23rd has swell around 8 feet from the SW, with a 14-second period, but the wind is cross-off at 20 km/h, making it a touch lumpy. The energy is strong at 2424. Friday the 24th drops to about 5 feet, still cross-off, and the energy is down to 859. By Sunday the 26th, a big one hits. Sunday afternoon has a massive 16-foot swell from the WSW, but the wind is ripping from the South at 25 km/h, tearing it up with a cross-chop. The energy is a beast at 7811, but it’s not for paddle surfing.
Monday the 27th is where it gets good. The swell settles to a solid 12 feet from the SW, with a 12-second period, and the wind eases to a light cross-off from the SSE. That’s a clean, powerful wave for the experienced, with energy at 4082.
The real standouts are at the end of July and start of August. Friday the 31st of July morning has 12 feet from the WSW with a very long 18-second period and a light cross-off breeze. The energy is huge at 7384. That’s a groundswell that will be peeling perfectly. Then, Saturday the 1st of August morning is the best of the lot: 12 feet from the SW, 15-second period, and a clean offshore breeze from the ESE at 25 km/h, energy at 5423. The afternoon gets even bigger, hitting 13 feet from the SW with the same offshore wind and energy at 8994. Expect crowds, but it’ll be worth it.
The second week of August keeps the swell, but the wind gets gnarly. Tuesday the 5th has a 13-foot SW swell with a long period, but by Wednesday the 6th, the wind turns onshore and blows everything out. Thursday the 6th and Friday the 7th are a total loss with near-gale winds and messy surf.
The hammer is Saturday the 1st of August for that clean offshore wind and huge SW groundswell. Friday the 31st of July is also a gem for the long period and clean conditions. The rest is a gamble.
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.
