The Lowdown

Righto, Rusty here. Let's have a look at what's on the menu for Bunbury Bay over the next couple weeks. Straight off the bat, there's a bit of a messy start. Sunday and Monday are a write-off with strong, cross-onshore winds and lumpy, poor conditions. Tuesday the 18th of August is a bit of a tease – the wind goes glassy in the morning and offshore in the afternoon, and there's a solid 10ft west swell pumping in. That's a big one though, pushing well past what’s comfortable for your average surfer. This is expert territory only, with the combined energy cranking at 4174. It's a powerful, long-period groundswell at 16 seconds, which might make it a bit tricky if it wedges up too straight, but on a good bank, it'll be a freight train. Water temps are about average for this time of year.

Now, the rest of the first week is a bit of a mixed bag. Wednesday and Thursday are messy with cross-onshore winds and marginal surf. But then, Friday the 21st of August morning looks decent. We've got a clean 8ft swell from the WSW, a nice cross-offshore wind from the ENE, and the combined energy is a strong 2216. It's a setup that should offer some fun, well-shaped waves for those who know what they're doing.

The following weekend, the 22nd and 23rd of August, the swell drops off but cleans right up. Saturday afternoon is calling out – glassy conditions with a 4ft WSW swell. It's not big, but it'll be clean and fun for a beginner session on a log. Sunday morning is also worth a look with a cross-offshore breeze and a similar 5ft swell.

Then there’s a long flat spell through Monday the 24th and Tuesday the 25th of August. The wind is howling onshore, and the swell is either tiny or blown out. No surf to speak of.

Looking further ahead, there’s a light at the end of the tunnel. On Saturday the 29th of August, the morning session looks like the pick of the whole forecast. Glassy conditions, a solid 8ft groundswell from the west with a very long 18-second period, and combined energy at 3456. This is a big, powerful, clean swell for experienced surfers. It’s a week out, so keep an eye on the charts, but it has all the hallmarks of a serious day at Bunbury.

The very end of the run on Monday the 31st of August also shows a glassy morning with a big 10ft swell, but that's again a bomb for experts only.

So, for the average surfer, the best bet is the end of the first week and the weekend just gone. For the experienced crew, keep that Saturday the 29th of August circled in your mind, but be ready for the crowds at Bunbury Bay.

Rusty.

Information about the Bunbury Bay Surf forecast

The above surf forecast table for Bunbury Bay provides essential information for determining whether the surfing conditions will be good over the next 16 days. A general guide to surfing at Bunbury Bay can be found by selecting the local surf guide option on the grey menu. Our Bunbury Bay 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 (Bunbury Bay) 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 Bunbury Bay 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.

Bunbury Bay is 3 km (2 miles) from the city of Bunbury. If you plan a holiday in Perth South Coast, 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.
