The Lowdown
Alright folks, Rusty here with a look at the waves coming our way. We’ve got a mixed bag ahead, but there is definitely some quality to be had if you’re patient.
The pattern starts off clean but a bit tricky, with longer-period SW groundswell and consistent NE winds to start. The water temp at Spot x is 64.2°, which is pretty much spot on for the time of year.
First up, Wednesday morning the 16th at Spot x. It’s a reef break, very consistent and exposed. We’ve got clean, 6.2ft of SW swell pushing in with a 13-second period, and the NE wind is holding steady at 12 mph in a cross-off position. The combined swell energy is moderate at 1299. It’s a bit of a session for the intermediate crew, nothing too outrageous. Then Wednesday afternoon cleans up even more with the wind dropping to a slight 3 mph from the north, still cross-off, with 4.9ft SW swell and 13-second period (energy 1079). This is looking like a good window for a fun session.
Thursday the 17th sees the swell dip a bit to 5.2ft in the morning, with a moderate breeze, but the quality holds. The afternoon turns cross with 4.3ft, which isn't as inviting.
Friday the 18th is a hard no. 25 mph north winds shred the morning, and by afternoon it’s a 14.8ft, 9-second NW slop with near gale-force winds. That’s a genuine kite-surfing setup, not for paddling.
We then hit a rough patch. From Friday afternoon all through to Monday the 22nd, the swell is big and powerful but the winds are onshore, cross-onshore, or just plain ugly. Saturday the 19th sees 14.8ft of WSW swell (energy 7442) with 22 mph onshore wind – a complete washout for paddle surfing.
The first real standout window arrives Monday morning the 21st of September. It’s still big with 11.5ft of SW swell from the west-southwest, period 15 seconds (combined energy a strong 5051), but the wind flips to a clean 12 mph cross-off from the north. It’s going to be a heavy, powerful groundswell – best suited for the more experienced surfer at this reef or point. The sets will be widely spaced with that long period, but the shape and energy will be superb. Crowds are possible out there.
The pattern stays big and messy through the rest of the week, with wind issues and onshore conditions dominating Tuesday through Thursday.
Then, look at this – Tuesday morning the 29th of September gets interesting. We’ve got a 9.8ft SW groundswell with a very long 17-second period pumping in (energy a strong 6015), and the wind is a light 6 mph from the west-southwest, which is onshore, but light enough that it’s just a slight bump. That’s a lot of water moving.
The true gem, though, is Wednesday morning the 30th of September. This is the best on offer. Glassy conditions – 3 mph from the north-northwest, offshore and glassy – with a solid 9.8ft SW swell, 16-second period, and a combined energy of 4056. The first hour or two of the day will be utterly perfect for the crew who can handle that size. That’s a session to mark in the calendar, but it’s ten days out, so keep an eye on it.
The outlook ends with a few workable afternoons on the first of October, but nothing that beats that Wednesday glass-off.

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.
