The Lowdown
Alright folks, Rusty here. Let’s have a look at what Bunbury Bay has got cookin’ for us over the next couple of weeks. It’s gonna be a bit of a mixed bag, so strap in.
First off, the water’s sitting at 62°, which is a bit colder than normal for this time of year – you’ll want that thick wetsuit for sure.
We’ve got a long period groundswell rolling in right from the get-go, but the conditions are touch and go. Thursday morning sees a clean 4ft W swell with a very long 15-second period. The wind is a light cross-off, which will keep the surface tidy, though the combined wave energy is on the weaker side (736). Thursday afternoon cleans right up with glassy conditions and a similar 4ft swell – that’s your best bet for a quiet, fun paddle on a beginner-friendly wave.
Friday gets messy. The swell picks up a bit but the wind turns onshore and it gets choppy, with the energy jumping way up (1257 to 1497) but the quality drops right off. Saturday and Sunday look pretty poor – onshore winds and lumpy conditions as the swell builds to 7ft. That’s getting a bit much for the beginners, and the onshore breeze is just gonna chop it up.
Now, Monday the 14th is a real standout for the crew who can handle it. We’ve got a clean 7ft W swell (14 secs) with glassy conditions and zero wind on the morning. The energy is strong (1715), and it’s marked as excellent for experienced surfers. This is the one to circle – long period groundswell, no wind, and a clean face. Tuesday the 15th is also a cracker, with a clean 6ft W swell and offshore ESE wind at 3 mph. It’s clean as a whistle and the energy is solid (1411). Another great morning session for the experienced crew.
After that, we hit a flat and windy spell from Wednesday the 16th through to Friday the 18th – onshore winds, messy, and dropping swell. A real write-off. Then Saturday the 19th throws a curveball – a massive 15ft swell rolls in, but it’s way too big for this break. The energy is immense (7582), but you’d be mad to paddle out unless you’re after a washing machine ride. Sunday the 20th calms down to a clean 7ft W swell with glassy morning conditions – another excellent window for the experienced surfer. The energy is still strong (1463).
The final week (21st to 25th) looks promising. Monday the 21st has a 10ft WSW groundswell (17 secs) with a clean cross-off wind, but that’s pushing the upper limit for even experienced guys. Energy is very strong (4133). From Tuesday the 22nd onward, the swell drops into the 5ft to 7ft range, and the wind turns offshore on the 23rd, 24th, and 25th. Those last three mornings, particularly the 24th and 25th, look real nice – clean offshore wind, long period WSW swell, and moderate energy. Good times for a proper session.
Best on offer: Monday 14th (7ft, glassy, experienced only) and Sunday 20th (7ft, glassy, experienced). For the less gung-ho, Thursday morning right now is your clean, gentle option.
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.
