Table - best surf conditions forecast for The Window over the next 16 days.
Alright folks, Rusty here. Let’s break down the next 16 days for The Window. It’s a reef setup, and it’s mostly going to be for advanced surfers, with some real standouts for those who know what they’re doing.
The first real surf kicks off Thursday, July 9th, but it’s not great. We’ve got a 8 ft swell from the WSW, but the wind is honking from the WSW at 12 mph, raking it onshore. The water is sitting at 66°, which is about average for this time of year. The combined energy is moderate (2978), but the conditions are just messy. You’d be better off waiting.
Moving into Friday, July 10th, and Saturday, July 11th, the swell hangs in there around 8 ft to 10 ft from the SW, but it’s plagued by cross-shore winds. The energy is still moderate (1328 to 3208), but the chop is making it a lumpy, frustrating session. A couple of the morning windows look cleaner, but nothing to write home about.
Now, Sunday, July 12th, is a mixed bag. The morning has a 10 ft SW swell with a 14-second period and light offshore winds from the WSW at 9 mph. The combined energy is solid (4479), and it’s a fair-to-middling session. But the afternoon turns to slop with a cross-onshore wind, and the rating drops to zero. Not worth the paddle.
The first real standout hits Monday, July 13th. This is the one. The swell bumps up to 12 ft from the SW with a very long 16-second period. The wind is light from the SSW at 6 mph, keeping it cross-shore and clean. The combined energy is strong (6882). This is proper groundswell, and it’ll be firing down the reef. With a period that long, it’s going to be powerful and lined up, but it’s big enough that it’s only for experts. The crowd factor is “sometimes” here, so expect a few others in the know, but it’s worth it.
Tuesday, July 14th, is another solid option. The swell is still 10 ft from the SW, with a 15-second period. The wind switches to a clean cross-offshore from the NE at 9 mph, and conditions are clean. The afternoon session is rated “excellent for experienced surfers” with a moderate energy (3420). This is a great window.
The rest of the week from Wednesday, July 15th, through Saturday, July 18th, sees a drop in quality. The swell pulses, but the wind gets strong again (19-25 mph), making it messy and dangerous. On Saturday, July 18th, the swell jumps to 13 ft from the SW, but it’s cross-offshore and clean, keeping the energy very strong (5197). That’s huge, thick, and only for the brave.
Then we hit a quiet patch. Sunday, July 19th, and into Monday, July 20th, the swell drops to 5 ft with a shorter 12-second period. The combined energy is weak (1040). But Monday morning is a gem: glassy conditions with the wind dropping to 3 mph. If you’re a beginner, that 5 ft on a reef might be too much, but for everyone else, it’s clean, small, and fun.
The second standout is Tuesday, July 21st. This is a late call, but it looks promising. A 6 ft SW swell with a very long 18-second period rolls in. The wind is glassy in the morning (3 mph from the NE), and the combined energy is moderate (3661). The afternoon gets a 8 ft swell with a 17-second period, clean cross-offshore winds, and a rating of “excellent for experienced surfers.” This is a long-period groundswell that will be peeling down the reef. Keep an eye on it, but it’s a week and a half out, so don’t bank on it.
The final days from Wednesday, July 22nd, to Friday, July 24th, see the swell hanging around 7 ft to 10 ft, with mostly clean conditions. Friday morning, July 24th, has a 7 ft SW swell, glassy winds from the ESE at 3 mph, and a rating of “excellent for experienced surfers.” The energy is moderate (1365). It’s a solid way to wrap up the run.
Bottom line: If you’re an expert, circle Monday, July 13th, and Tuesday, July 21st, on your calendar. The first is more certain, the second is a long-range promise. The Window is a reef, so it handles the long-period swell well, but it’s not for the faint of heart. If you’re a beginner, wait for the glassy Monday, July 20th, and enjoy the small stuff.

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.
