The Lowdown

G’day, it’s Rusty here.

We’ve got a bit of a mixed bag coming up for the next couple of weeks. The big news is that we’re looking at a solid, long-period west swell rolling in right away, but it’s going to be a wild ride before things settle down. The water’s sitting at 62°F, which is a touch colder than normal for this time of year, so you’ll want the hood and booties.

Tuesday morning kicks things off with some serious size – we’re talking 10ft of raw west swell, with a long 16-second period. The energy is strong, reading 5081, but it’s just too much juice for this spot. It’s going to be a washing machine, and honestly, it’s only for the most experienced, and even then, it’s a bit sketchy. The afternoon stays big and the wind picks up, making things messy. We’re really just watching this one from the beach.

Wednesday sees the swell drop a touch to 8ft, but the wind turns cross-on and it gets choppy. The energy is still moderate, around 2797, but it’s not looking clean. I’d give this one a miss.

Now, here’s where things get interesting. Thursday morning is the standout for the first week. The swell has backed off to a very manageable 8ft, still from the west with a 16-second period, and the wind is completely glassy. It’s the calm before the storm, and the surf will be absolutely pristine. This is your window if you’re an experienced surfer looking for some proper, powerful waves. The energy is still strong at 2702, so there’s plenty of push, but it’s clean. Bunbury Bay is the call.

Friday morning is another good one. The swell is down to 6ft from the west-southwest, and again we have glassy conditions with the wind coming from the ESE, which is offshore here. It’s a little less powerful than Thursday, but the quality will be excellent. This is a great option for a solid session without the intensity of the day before.

Saturday morning has a bit of size at 5ft, and it’s glassy again, so there are fun waves to be had. But the afternoons this week all get chopped up by onshore breezes, so make the most of the mornings.

Sunday’s surf drops off, and things get more marginal. We’ve got a long lull coming. From Sunday afternoon through to the end of the month, it’s pretty much a write-off. The swell fades and the wind is consistently onshore or cross-onshore, making the surf messy. There are a few poor days in there, with some strong breezes and rain showers, and the energy drops off significantly. It’s a blank run that I’m calling from the 23rd to the 29th. You’re better off waxing your longboard or doing some repairs.

Looking further ahead, there’s light at the end of the tunnel. Sunday the 30th, in the morning, looks promising. The wind goes glassy, and we’ve got a 5ft west swell with a 15-second period. It should be clean and workable, a nice return to form.

But the real gem of this whole forecast is Monday the 31st, in the morning. The wind is completely calm – dead zero – and we’ve got a solid 7ft west swell with a 16-second period. The energy is back up to 2389. This is going to be a fantastic day. Clean, powerful, and surfable, especially for those who know what they’re doing. This is the other standout, two weeks out, so don’t book your Monday off just yet, but it’s looking very good.

After that, the first week of September looks like it backs off a bit, with the swell dropping to around 7-8ft, but the winds turn a little cross-on, so it’s not as clean as that Monday. There’s still surf, but the magic of that glassy morning is gone.

So, to sum it up: the first couple of days are too big, the middle of the first week is the best bet for quality, and then we have a long flat spell before the action starts again at the very end of the month. Get out there when you can.

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.
