The Lowdown
Alright, Rusty here. Let’s talk about what’s coming up for Spot X.
First off, the water is sitting at 67°, which is a touch warmer than normal for this time of year – not a bad thing when you’re paddling out. The surf’s about to kick off with some real muscle, but you’ve got to be patient because the early part of the window is a write-off for most.
We’re looking at a big, long-period SW groundswell hitting on Tuesday the 11th of August. Swell heights are punching 18 ft in the morning with a 16-second period, packing a massive 15270 units of energy. That is serious, heavy water. But the wind is a fresh 19 mph cross-onshore, so it’s going to be lumpy and messy. Only the most experienced chargers would even think about it, and honestly, it’s too big for this reef. By the afternoon, the wind backs off a bit but it’s still choppy.
Wednesday the 12th is still bumpy with onshore winds and questionable tide conditions. Not worth paddling for.
Now, Thursday the 13th of August morning is where it gets interesting. The swell is still a solid 12 ft from the SW with a 16-second period, but the wind swings to a light N at 3 mph, giving us clean, cross-offshore conditions. The energy is still strong at 7410. This is a proper window for expert surfers only – the size is demanding, but the clean lines will be there. Definitely the standout of the first week.
Friday the 14th morning follows a similar theme: 12 ft SW swell, clean cross-off wind from the NE. Solid, but keep an eye on the crowd factor – it’s a spot that gets surfed sometimes, so you might have some company.
The weekend leans into a slight drop in size. Saturday the 15th and Sunday the 16th bring 8 ft to 10 ft WSW swell with nice offshore winds, but the energy is moderate. Experienced surfers will find fun waves, but nothing compared to Thursday.
After that, we hit a rough patch from Monday the 17th through to Wednesday the 19th. The wind cranks up hard, especially on Wednesday the 19th with a 28 mph cross-onshore making a total mess of the big 18 ft swell. That’s more kite-surfing territory than paddle surfing.
The second week is a mixed bag. Thursday the 20th and Friday the 21st of August offer cleaner conditions with gentle offshore breezes, but the swell sits around 12 ft with moderate energy. It’s good, but not a standout.
The real long-range highlight looks like Sunday the 23rd of August morning. We’ve got an 12 ft WSW swell with a very long 19-second period, and a light 6 mph cross-on wind, but the energy is strong at 9342. That’s a beautifully lined-up groundswell, perfect for this reef. Keep an eye on it, but it’s still a way out, so that’s promising but less certain right now.
From Monday the 24th onward, the wind goes ballistic again – near gale force – and blows everything out through to Wednesday the 26th. Surf will be poor, jumbled, and not worth the effort.
So, to sum it up: Thursday the 13th of August is your best bet for quality, heavy, clean waves for the experts. And if you can wait, Sunday the 23rd of August has some serious potential if the wind plays nice.
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.
