The Lowdown
G’day, Rusty here. Gotta be honest with ya – we’ve only got the one break in the mix, Bunbury Bay, and she’s been a bit of a handful lately. This isn’t a multi-spot smorgasbord; it’s a single-wave story, and for the first few days, it’s a story about sizing up and waiting. The water’s sitting at 61°F, which is a bit colder than normal for this time of year – you’ll feel that chill on the paddle out.
The real buzz starts building from Tuesday the 11th, but don’t get too excited just yet. That morning, a solid 10ft WSW groundswell with a very long 16-second period is hammering the coast. The combined energy is massive at 4030, and honestly, that’s way too much heft for a fairly exposed spot. It’s churning out a cross-shore wind too, so it’s messy and huge – more of a tow-in or a watch-from-the-cliffs situation than a paddle session. The afternoon drops to a still-chunky 8ft, but it’s on a cross-onshore wind, making it choppy. Not the day to get wet.
Wednesday the 12th is a step down, but not a pretty one. You’ve got 6ft and 6ft swells from the WSW with a 15-second period, but the wind is all wrong, blowing light cross-onshore and putting a ripple on the face. The energy is moderate (1312 and 1185), but the conditions are marginal – you’d be scratching for a ride.
Now, Thursday morning the 13th – that’s where we get a little window of goodness. The swell has settled to a clean 6ft from the WSW with a long 16-second period, but the real magic is the wind: dead calm, glassy as a mirror. The combined energy is 1676, which is a nice, punchy moderate level. This is a proper session for experienced surfers – that swell will be lining up clean, but those long-period sets will peel fast along the bank. It’s not a beginner wave at this size and with that power.
Friday morning the 14th is another bright spot. You’ve got 6ft WSW swell with a 16-second period, and a light cross-offshore breeze (5 mph) is keeping the faces clean. Energy is 1708 – solid moderate. This is your other standout for the first week: glassy-offshore texture, decent size, good energy. Crowds can happen here sometimes, so get in early.
The weekend drifts into smaller, cleaner conditions. Saturday afternoon the 15th is a real treat if you want something mellow – 4ft WSW groundswell, glassy as, and combined energy of 684 (weak, but fun on a longboard). Sunday afternoon the 16th jumps back up to a glassy 7ft W swell with a 15-second period and 1709 energy – another strong option for the experienced crew.
Then it turns ugly again. Monday the 17th through Wednesday the 19th brings strong onshore winds, rain showers, and a massive spike of energy – 7127 on Wednesday morning the 19th with an 12ft W swell and 22 mph onshore wind. That’s a washing machine, not a surf break. Steer clear.
The outlook brightens a fair bit from Thursday the 20th. Thursday morning is a clean 7ft W swell with a cross-offshore breeze and 2182 energy – excellent for experienced surfers again. Thursday afternoon is 7ft and glassy. Friday the 21st keeps the clean runs going with a 5ft and 6ft swell under light offshore winds. Saturday the 22nd is smaller (5ft) but still clean – good for a cruise.
Looking into the second week, we get another pulse of long-period energy late. Sunday the 23rd sees a 7ft to 8ft W swell with a very long 19-second period, cross-onshore wind, and energy around 3219 to 3841. It’s promising, but the wind is just okay, and that super long period will make it top-heavy and tricky on a beach break – it’ll want to stand up and throw. Monday the 24th gets blown out by fresh to strong onshore winds and rain, and Tuesday/Wednesday the 25th and 26th stay messy and small. Not much to chase there.
Overall, the standout windows are Thursday morning the 13th, Friday morning the 14th, and Sunday afternoon the 16th for the first week, then keep an eye on Thursday the 20th and Friday the 21st for clean, quality waves. The big grinding stuff in between is just noise – wait for the calm, and you’ll get your score.
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.
