The Lowdown
Alright folks, Rusty here. Let’s take a look at what’s cooking for Bunbury Bay over the next couple of weeks.
This is a mixed bag, with a bit of a slow start, a couple of really nice windows, and then a big, powerful finish that might be too much of a good thing. The water is sitting at 64°F which is a bit colder than we’d usually expect for this time of year, so you’ll want the wettie zipped up.
The first real chance to get wet doesn’t hit until Tuesday morning, the 21st of July. We’ve got a clean 4ft swell from the WSW with a solid 14-second period pushing in. The wind is a gentle cross-offshore breeze, which should keep the faces tidy. The combined energy is moderate (642), so there’s some push. It’s not the biggest, but it’s clean and surfable for a beginner-friendly break.
The standout, without a doubt, is Wednesday the 22nd of July. Wednesday morning kicks off with a glassy 4ft swell from the WSW and a light offshore breeze out of the east – that’s a recipe for perfection. The combined energy is ramping up (730). Then in the afternoon, it gets a bit punchier with a 5ft swell (just about the limit for a comfortable session here) and a clean 15-second period, with a solid offshore wind. The energy is strong (1001). This is the best window of the entire forecast. Thursday afternoon the 23rd also looks sweet with a glassy 3ft swell and very light winds.
We hit a bit of a lull from Friday the 24th. The swell drops right off to 2ft, and through the weekend it’s mostly small and messy with cross-shore winds. Then Sunday the 26th of July, the wind kicks up hard from the north, making a mess of the 8ft and 7ft swell. That’s a no-go for the paddle crew.
The first week of August gets interesting, but in a heavy way. By Monday the 3rd of August, we’re looking at massive 10ft groundswell from the west, with a very long 15-second period. The combined energy is extreme (4636). The wind is onshore, so it’s going to be a washing machine. It’s an expert-only situation. Tuesday the 4th of August shows a massive 13ft swell (energy at a whopping 7996). Even with a gentle breeze, that’s far too big for this spot. This setup looks more like a kite surfing playground than a paddle session.
So, to wrap it up: get out on Wednesday the 22nd for the best of it. The Tuesday before and Thursday afternoon are also solid. The rest is either too small, too windy, or way too big.
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.
