The Lowdown
G’day, Rusty here. Let’s talk about Spot x in feet, miles per hour, and degrees Fahrenheit.
The first couple of days are a write-off. Monday August 17th and Tuesday August 18th have strong onshore winds and big, messy swell—not worth getting wet for. The water’s about 66°F, a touch warmer than average.
Wednesday August 19th shows some promise. Winds go offshore from the WSW with a gentle breeze. Swell’s a meaty 13 ft to 15 ft out of the west-southwest, period 15 to 16 seconds. That’s groundswell, so better shape and longer lulls. Combined energy is high, between 7531 and 9362. Wednesday afternoon with clear skies and that offshore wind could be decent for experienced surfers.
The standout is Saturday August 22nd morning. Glassy conditions—zero wind. A 10 ft swell from the southwest, period 16 seconds, rolling into the reef. Combined energy is 4181. The wave quality is excellent. This break is very consistent, exposed, and loves that WSW direction. It’s intermediate-level, so 10 ft is too big for beginners. Crowds are possible here. This is the session to aim for.
Sunday August 23rd and Monday August 24th get messy again with onshore winds and a 12 ft to 15 ft swell.
Tuesday August 25th morning offers another glassy window, with ENE wind at just 3 mph. A 10 ft southwest swell, period 11 seconds. Combined energy is 2955. Excellent conditions for experienced surfers—this is your second best option.
Thursday August 27th morning is glassy again, with a 8 ft WSW swell, period 15 seconds, and combined energy of 2351. Clean and worth a look.
After that, it’s mostly windy and rough leading into Tuesday September 1st, with a big 13 ft to 16 ft swell but poor conditions—only for experts, and even then it’s ugly.
Best waves: Saturday August 22nd morning. Glassy, 10 ft southwest groundswell with a 16-second period. If you miss that, Tuesday August 25th morning.
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.
