The Lowdown
G’day, Rusty here. Let’s break down what’s cookin’ at Spot x.
The week starts off a bit rough. Wednesday sees a big WSW groundswell, but it’s hammered by strong cross-onshore wind. Thursday’s a little better but still on the messy side. Friday the 21st of August is the first real gem – glassy, clean, 3.5m SW groundswell (5329 energy). That’s exceptional surf for the experienced crew. Saturday and Sunday are blown out, so take a rest.
Monday the 24th and Tuesday the 25th are marginal or poor, with strong winds. Then Wednesday the 26th of August brings another big WSW pulse with energy over 11000 – that’s a lot of power – but the morning has onshore wind, though the afternoon cleans up a bit. The second standout is Thursday the 27th of August: gentle offshore ENE wind, 3.0m SW groundswell (3699 energy), and clean conditions. That’ll be excellent for those who know what they’re doing.
The end of the month and start of September offer smaller but clean windows. Friday the 28th of August has clean 1.8m SW swell, and Tuesday the 1st of September gives you 2.1m SW with clean cross-off winds. The two best days are Friday morning the 21st of August and Thursday morning the 27th of August – both solid, clean, and for experienced surfers.
Water temp is about average for the season. Spot x can see crowds sometimes, but when it’s this good, it’s worth it.
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.
