The Lowdown
Alright folks, Rusty here. Let's have a look at what Bunbury Bay is cooking up for us over the next couple of weeks.
The water is sitting at 61° right now, which is a bit colder than normal for this time of year – you'll be wanting a decent 4/3.
We've got a bit of a slow start, but Friday the 28th kicks things off with some clean lines. The morning sees a 4ft swell out of the WSW, a period of 13 seconds, and clean offshore winds from the SE at 15 mph. The combined energy is moderate at 433, but it's clean and rideable. The afternoon stays in that same sweet spot, dropping just a touch to 3ft, but still offshore and clean.
The real highlight of this first stretch lands on Saturday the 29th. Saturday morning pumps up the volume with a 4ft swell from the WSW, but the period jumps to a very long 19 seconds – that's proper groundswell energy. The combined energy is already strong at 949. But it's the afternoon that gets the blood pumping: 5ft of swell from the WSW, 18 seconds of period, and clean offshore wind from the ESE at 9 mph. The energy jumps to 1447, making for excellent surf for those with a bit of experience. This is the best wave of the early run.
Sunday the 30th gets a little trickier. The swell pushes up to 6ft in the morning, which is getting big for beginners, but the wind swings cross-shore from the NNE. The afternoon drops to 6ft but goes cross-onshore from the WSW. The energy is high, but the quality is marginal.
From Monday the 31st through Tuesday the 1st of September, the wind turns more onshore or cross-onshore, and the swell hangs around 5-6ft but with a shorter period of 15-17 seconds. It's going to be choppy and messy. Not worth paddling out for.
Wednesday the 2nd and Thursday the 3rd are pretty flat and poor, though Thursday the 3rd morning throws a surprise – 6ft of WSW swell, 14 seconds, and glassy conditions with the wind from the NNW at just 3 mph. That's clean, but it's a tough call with the onshore winds forecast for the afternoon.
Friday the 4th and Saturday the 5th are a write-off, with strong winds and messy conditions. Sunday the 6th sees the swell drop right back to 4ft, but the wind stays messy.
Then we get a little pulse of clean 3ft surf on Monday the 7th with an offshore wind from the NE, and a bit more size on Tuesday the 8th with 4-5ft, but it's all a bit average.
Now, for the second week, the real standout is showing up. Wednesday the 9th of September has a 7ft swell in the morning, but the afternoon is the session to circle. It builds to 8ft from the W with a 16-second period, and the wind goes dead calm – glassy conditions. The combined energy is very strong at 3438. This is solid, powerful groundswell, and it'll hold its lines well over the reef at Bunbury Bay. This is expert territory, as 8ft is pushing into big-wave country. It's your best bet in the second week.
Thursday the 10th is just too big at 10ft for this break – even with decent wind, it'll be maxed out and dangerous. The swell stays big through the 11th and 12th, but the wind is onshore or cross-onshore, so it'll be a messy, washed-out mess.
So, to wrap it up: your best windows are Saturday the 29th of August afternoon, and if you're an experienced surfer hungry for some size, the afternoon of Wednesday the 9th of September is the one.
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.
