The Lowdown
G'day, I'm Rusty.
Let's have a look at what's on the cards for Bunbury Bay. The next couple of weeks are a bit of a mixed bag, but there are a couple of windows that look pretty special.
The first real sniff of action comes in on Sunday the 19th, but it's a bit of a messy one. We've got a 7ft west swell rolling in, but it's coming with a cross-on breeze and a fair bit of chop, so honestly, it's looking more like a paddle out of frustration than a session to remember. The swell drops a touch on Monday morning the 20th to 4ft, swinging around to the WSW, and the wind goes glassy. That's a nice morning for a beginner to get a few small, clean ones with the period at 13 seconds, giving the waves a bit of shape. The energy is moderate (518). The water temp is sitting at 64°, which is about average for this time of year, so no surprises there.
The pattern builds through the week. Tuesday the 21st and Wednesday the 22nd see the swell holding steady around 4ft to 5ft from the WSW, and we get a clean run with light cross-offshore winds. Wednesday afternoon is the pick of this early run, with the swell pushing 5ft, a 15-second period, and the energy jumping up to 773 (moderate). The wind is light and cross-off, so you're looking at clean, lined-up waves. Keep in mind this spot can get a few people, so you might have some company.
Thursday the 23rd stays small and clean, but by Friday the 24th, the wind picks up onshore and the swell drops to under 3ft, pretty much killing the vibe. That poor run hangs around for a few days. There's a notable gap here with no real recommendations until the following week.
Now, here's where it gets interesting. Late in the forecast window, we've got a couple of absolute standouts, but you need to be an experienced surfer. On the 31st of July, Friday morning, the forecast is showing a massive 10ft west swell with a 17-second period and glassy conditions. The combined energy is a massive 5305 (very strong). This is a proper groundswell with heaps of power. However, the buzzer is that it's predicted to be too big for this break. Bunbury Bay is a beginner-friendly spot, and at 10ft, it's going to be washing over the reef and closing out. This is expert-only territory, and even then, you'd need to be very wary. The same goes for Saturday the 1st of August, with another 12ft to 10ft west swell.
The true standout, the one I'm circling on the calendar, is Sunday the 2nd of August. The morning looks sensational. The swell has dropped to a more manageable 8ft from the WSW, with a 15-second period and light cross-offshore winds. The energy is still strong at 2510. This is the sweet spot. It's still big enough to be for experienced surfers only, but it's not the insane, dangerous size of the days before. The wind is clean, the swell direction is perfect for the break, and you'll have long, powerful sets. If you've got the skills, this is the session to chase.
So, for the beginner, the best window is Monday the 20th and Wednesday the 22nd of July. For the experienced crew, keep your eyes on Sunday the 2nd of August. It's a long way out, so the forecast could change, but it's looking like a cracker.
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.
