The Lowdown
G’day, Rusty here. Look, I’ve had a good squiz at Bunbury Bay and the next couple of weeks are a bit of a mixed bag. The first week is pretty ordinary with a lot of cross-onshore wind messing things up, but there’s a couple of windows that’ll get a surfer’s heart rate up if you’re patient.
Right now, we’re in a flat spell with no surf worth paddling out for. The first real chance doesn’t come until Tuesday the 8th of September. Before that, we’ve got a long stretch of poor surf and junk wind. The swell starts showing mid-week, but it’s chopped up by cross-onshore breezes. Thursday the 4th and Friday the 5th see some 8ft waves, but the wind is all wrong—gusty onshore and lumpy. Not worth it. Saturday the 6th is no better with a 28 mph wind making it a write-off for paddle surfing; that setup looks more interesting for kite surfing.
Now, the standout. Tuesday the 8th of September is your day. Early morning we’ve got a solid 8ft swell rolling in from the west, with a long period of 16 seconds—that’s proper groundswell, loads of energy. The combined swell energy is strong at 3470. The wind swings offshore from the ESE at a moderate 16 mph. That means clean, peeling waves for the experienced crew. This is solid size—over 8ft—so it’s for the experts only, and with the long period, expect better shape but longer gaps between sets. The afternoon stays clean with a gentle offshore from the east at 9 mph, and the swell holds at 8ft from the WSW. This is the best on offer, no question.
The water is sitting around 63°F with a small anomaly of -0.9°F, so pretty average for this time of year, nothing unusual.
We also get another chance on Friday the 11th of September. Morning sees a 6ft west swell with a 15-second period and clean conditions thanks to a cross-offshore from the SSE. The energy is moderate at 2030. Afternoon gets even better with 5ft west swell and a light offshore from the ESE, clean faces. That’s a good one for a smaller board but still plenty of fun.
Saturday the 12th of September morning is another gem. Light offshore wind from the ESE, 6ft west swell with a very long 16-second period, and the energy is moderate at 1440. Clean lines, nice shape. It’s not huge, but it’ll be quality.
After that, the surf fades. Sunday the 13th drops to under 3ft and the wind goes light and variable. Then Monday the 14th and Tuesday the 15th see a big bump back up to 8ft, but the wind is onshore or cross-onshore again, making it messy. By Wednesday the 16th of September, the swell is 10ft with onshore wind—too big and ugly for this spot. A real shame.
Bottom line: Tuesday the 8th is the standout. If you’re an experienced surfer, that’s the session. Friday the 11th and Saturday the 12th are also quality, but smaller. The rest of the window is best spent on other things.
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.
