The Lowdown
Alright, Rusty here, your local surf scout. Let's break down what's on the menu for Bunbury Bay.
First thing you need to know – the next couple of days are nothing to get excited about. We've got moderate onshore winds and weak surf, so don't rush out. The first real window to paddle out is Monday, September 14th. That morning, we get a clean 6ft WSW swell with light offshore ESE winds, switching to a moderate offshore SE breeze in the afternoon. Wave energy is solid (1512), and with a 14-second period, expect long, well-formed walls. This is the best call for experienced surfers in the early stretch. Water temp is 62°, just a touch below average, so you'll want your spring suit.
Tuesday the 15th keeps it going – morning waves at 6ft with clean cross-offshore winds, dropping to 5ft in the afternoon with light airs. Good, clean surfing, but Monday morning is your best bet.
Then from Wednesday the 16th through Friday the 18th, the wind turns onshore and the swell disappears to tiny, choppy mush. Not worth your time.
Now for the big stuff. Saturday, September 19th, we’ve got a solid 10ft WNW swell rolling in. The wave energy is pumping (3594) with a 14-second interval, but this is too big for Bunbury Bay unless you're an experienced charger. Even then, it's on the heavy side. Sunday the 20th stays big with even more energy (4438), but the wind switches onshore, making it lumpy.
Monday the 21st through to Thursday the 25th is mostly onshore wind and weak, messy surf. One hopeful note – Friday afternoon, September 25th, shows a clean 5ft WSW swell with moderate offshore SE winds. It’s not huge, but with decent energy (1298) and clean conditions, it’s a solid option for the second week.
So, the absolute standout to circle on your calendar is Monday morning, September 14th – 6ft WSW swell with light offshore winds, 14-second period, and moderate wave energy (1512). Clean, powerful, and worth the wait.

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.
