The Lowdown
Alright folks, Rusty here. Let’s have a look at what Bunbury Bay has got cooking for us over the next couple of weeks. Straight up, the first couple of days are a bit of a write-off, so don’t bother paddling out until we get past the weekend.
The first real chance to get wet comes on Wednesday, 12 August. It’s been a long wait, but we’ve got a decent window. The swell is a solid 7ft from the WSW, with a very long period of 16 seconds, which is proper groundswell energy. The combined energy is pumping at 2276, so there’s plenty of grunt in the water. The wind is glassy out of the NNE, which is going to leave the surface like a mirror. This is clean, powerful surf, but at 7ft, it’s pushing into the big stuff, so this is one for the experienced crew only. This isn’t a beginner’s wave. The water is sitting at 62°, which is a bit colder than normal for this time of year, so you’ll want a decent wetsuit.
That Wednesday morning session is the standout for the whole outlook. The following days soldier on with similar-sized swell, dropping slightly to 7ft to 7ft, but the wind shifts around, going cross-on or onshore, which messes with the surface. The swell period stays long, over 15 seconds, so there’s still quality, but the wind isn’t playing ball. Crowds are possible here, it can get busy, so for that Wednesday morning, you’ll want to be out early.
After that, there’s a long dry spell starting from the 15th. The wind gets up into the 20s and 30s mph, and the swell sticks around at 8ft to 13ft, but it’s just messy. The setup looks more interesting for kite surfing than paddle surfing honestly. The wind is just too strong. By the 19th, the swell drops to 5ft, and the wind is clean from the SSW, but it’s only marginal. The 20th looks promising again with a 10ft WSW swell and a light E wind, but the forecast says it’s just too big for this break, so it’s a tease.
So, bottom line: if you’re an experienced surfer, mark your calendar for Wednesday morning, 12 August. That’s your best shot. The rest of the window is either blown out or too big for this spot. Don’t get your hopes up for the long-range stuff; it’s a gamble.
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.
