The Lowdown
Alright, Rusty here. Let’s have a look at what’s cookin’ at Spot x.
Right now we’re in a bit of a rough patch. That big westerly swell rolling in on the 17th is packing some serious punch with combined energy readings up around 8700 to 8856, but it’s blowing a gale from the west, peaking at 31 mph, and the surf is just poor. That's nearly 18ft of messy, onshore slop – definitely not one for the quiver.
We’ve got a long stretch of questionable conditions through the first week. The swell sticks around, but the wind stays ugly, mostly onshore or cross-onshore through until the morning of Saturday the 22nd. That’s a solid five days of waiting.
Now, Saturday the 22nd morning is where I start to get a bit excited. The wind drops to absolute glass – 0 mph – and we’ve still got a solid 10ft swell rolling in from the southwest with a long 16-second period. That’s a groundswell with plenty of energy (4075). The glassy conditions mean the surface will be like a mirror. This is excellent for experienced surfers. The water temp is a touch warmer than normal at 66°, about 3° above average, so it’s a tiny bit balmier than usual for this time of year. Spot x is a very consistent reef break here, exposed to the swell, and its optimum direction is WSW, which is spot on for this swell. It’s a setup that handles long-period energy well, so the shape should be solid. Crowds are sometimes an issue here, and with conditions this good on a Saturday morning, you can bet there’ll be a few others thinking the same. This is the standout of the whole period.
After that Saturday high, things go south again. Sunday the 23rd sees strong breezes kick up, and the whole next week is a mix of messy cross-shore winds and poor surf quality. Not worth paddling out.
But then, look at the last few days of August and into September. The swell picks up again big time. On Saturday the 29th, we’ve got a 15ft swell from the WSW with a 16-second period, combined energy hitting 10150. Wind is offshore from the north at 16 mph, keeping things clean. That’s a big, powerful swell, over 8ft, so definitely for experts only. It’s more than a week away, though, so keep an eye on the long-range forecasts – this one has promise but isn’t locked in. That 15ft on the 29th morning, with offshore wind, is the other true standout in the window.
There’s another pulse on the 1st of September, with an 18ft monster from the southwest, but the onshore winds return, so it’s likely a pass for paddle surfing.
So in short: the first five days are a write-off. The absolute best chance you’ve got is Saturday the 22nd morning for some clean, powerful waves at head-high-plus. Then get ready for a potentially epic, big swell window on the 29th. The rest? Leave it for the kites.
Rusty.

Information about the Spot x Surf forecast
The above surf forecast table for Spot x provides essential information for determining whether the surfing conditions will be good over the next 16 days. A general guide to surfing at Spot x can be found by selecting the local surf guide option on the grey menu. Our Spot x 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 (Spot x) 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 Spot x 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.
Spot x is 75 km (47 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.
