The Lowdown

Alright folks, Rusty here. Let’s take a long, hard look at what’s on the table for Bunbury Bay over the next couple of weeks. Gotta be straight with you – the start of this period is a write-off. There's a big gap of about 4 days with no worthwhile surf, thanks to a massive, raw swell that’s just too powerful and messy for this spot.

The first real glimmer of hope comes in on Wednesday morning, 12th August. The ocean finally drops to a more manageable 6ft groundswell from the WSW, with a solid 15-second period. But the real story here is the wind – dead flat calm, glassy conditions. That's the kind of morning you paddle out for. The wave energy is moderate at 1312, so it’s not a beast, but it’ll be clean, lined-up, and a joy. Expect some very clean, workable waves.

Now, the standout window for the experienced crew is Thursday morning, 13th August. The swell holds at 6ft from the WSW, period stretches out to a very long 17 seconds, and it’s glassy again. The wave energy jumps to a solid 1758. This is a groundswell with serious legs. For a spot like Bunbury Bay, that long period means the waves will have great shape and power, but at a beach break it can get a bit walled and tricky. This is why it’s flagged for experienced surfers only. The water’s a bit colder than normal at 62°F.

Friday morning, 14th August is another one to keep in mind. We’ve got 6ft WSW swell at 16 seconds, with a light offshore breeze from the NE. That’s clean, that’s glassy, that’s you getting a head start on the peak. Wave energy is still strong at 1708. This is probably the best all-rounder for the average surfer who can handle a bit of size.

The wave energy starts to fade from Saturday the 15th into Sunday the 16th, dropping below 1000 and getting a bit smaller and messier. Just background waves.

Looking further out, there’s a flash of hope on Saturday morning, 22nd August. After a run of strong, messy westerly winds and lumpy 8ft+ surf, we get a reprieve. The swell drops to 6ft from the WSW, period is a nice 16 seconds, and the wind is light from the NE. The wave energy is back up to 1685. The forecast says "excellent surf conditions for experienced surfers." It’s 10 days away, so don’t bank on it, but it’s the best thing on the long-range radar.

For the rest of that second week, expect onshore winds and lumpy, unappealing conditions. This spot can get a bit interesting for kite surfing when the wind is up and the swell is chunky, but for a paddle surfer, most of it’s a pass.

So, to sum it up: don’t bother before Wednesday morning the 12th. Thursday morning the 13th is for the experienced crew. Friday morning the 14th is the best bet for most of us. And keep a loose eye on Saturday the 22nd.

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.
