The Lowdown
G’day, it’s Rusty here. Let’s be straight with you – the next couple of weeks at Bronte Beach are a mixed bag, and honestly, there’s not a whole lot that’s gonna have you paddling out in a hurry. We’ve got a long stretch ahead, and a lot of it is pretty average. But there are a couple of little windows where it might just come together, if you’re patient.
First up, this Sunday the 16th is a write-off. We’ve got a cross-onshore breeze and a choppy mess on the cards. There’s a bit of swell, around 5ft, but it’s short-period and weak, with the combined energy only reading 282. It’s just messy. The water temp is sitting at 61°F, which is nearly 3°F colder than normal for this time of year – so you’ll want the full steamer and booties.
Monday the 17th is much the same – light rain, cross-on winds, and small, weak waves. Not worth the effort. The energy’s dropped right off into the 160s – we’re talking weak, gutless stuff.
Tuesday the 18th is where we see the first little glimmer. The morning turns glassy with about 3ft of swell, but the period is only 7 seconds – short and crumbly. It’s surfable, but very ordinary. The energy is still weak at 137. You’d be scratching for a wave. The afternoon drops off to nothing.
Wednesday the 19th has a clean morning with a light cross-offshore breeze and a 2ft wave. Again, it’s small and weak, energy at 165. Not terrible, but not memorable. The afternoon turns cross-on and choppy again.
From Thursday the 20th through Saturday the 22nd, we’re in a flat spell. The energy readings are barely registering – down in the 50s and 60s. There’s nothing doing. Friday has a clean-ish look, but with a 3ft wave and weak energy, it’s not worth wetting a suit. Saturday afternoon, a fresh southerly kicks up to 22 mph with a quick 7ft of swell but that’s got a 474 energy reading and cross-shore winds – it’s a lumpy, blown-out mess. Not for surfing.
Then comes the first real standout. Sunday the 23rd, morning. The wind goes light and offshore, the sky clears, and we get a clean-looking 5ft of swell from the south with a 9-second period. The combined energy is 326 – moderate, but the conditions are right. This is your best bet in the early part of the week. It’ll be clean and lined up on the reefs and banks. Not huge, but fun. Keep an eye on the tide.
Monday the 24th is another ordinary one – moderate offshore breeze, but the swell is tiny (3ft) and the energy is weak. Forget it.
Now, let’s fast-forward to the end of the window. This is where it gets interesting. Tuesday the 25th has a real pulse. The morning sees 8ft of south swell with a 9-second period, and the energy is cranking at 1109 – that’s strong. The wind is cross-offshore and the surf looks clean. This is a solid, powerful day for the more experienced crew. The afternoon gets bigger (8ft) and the period stretches out to 12 seconds, but the wind turns onshore and it gets lumpy. The morning is the window.
Wednesday the 26th is still sizable – 6ft from the SSE – but a fresh, cross-offshore breeze and 596 energy. It’s clean, but there’s a bit of push in it. This is a decent option if you missed the Tuesday morning. After that, it fades out again through the rest of the week.
By the 27th and onwards, we’re back to small, weak surf, with the odd clean morning but nothing with any power. The energy readings are back down into the 100s and below. The 28th onwards is pretty flat, with a couple of clean but tiny waves. Not worth planning around.
So, to sum it up: the standout window is Tuesday morning, the 25th – that’s the big one. Strong swell, decent period, clean lines. The next best is Sunday the 23rd morning – smaller but still clean and fun. If you can’t make those, there’s not a lot else. The water is colder than usual this week, so be ready for that.
Given the conditions we’re looking at, especially on Saturday afternoon with that strong cross-shore wind and 7ft of messy swell, that setup is going to be more fun if you’ve got a kite than a paddle board. It’s just not a surfable wave.
That’s the outlook, mates. It’s patchy, but there are a couple of gems in there if you’re keen. Stay patient.
Rusty.

Information about the Bronte Beach Surf forecast
The above surf forecast table for Bronte Beach provides essential information for determining whether the surfing conditions will be good over the next 16 days. A general guide to surfing at Bronte Beach can be found by selecting the local surf guide option on the grey menu. Our Bronte Beach 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 (Bronte Beach) 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 Bronte Beach 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.
Bronte Beach is 4 km (2 miles) from Randwick. If you plan a holiday in Sydney South Coast, look for hotels and other accommodation in Randwick. Randwick has rooms for a wide range of budgets as well as car hire and transport links.
