The Lowdown
G’day, Rusty here. Look, it’s a tough old run for a while around Bronte Beach. We’ve got a bit of a dry spell to start, but the back half of the forecast brings some serious size – though it comes with its own set of challenges.
For the first four or five days, it’s honestly pretty grim. We’re looking at small, weak, and mostly onshore chop. There’s nothing really surfable for the weekend of the 12th or the start of the week. You’d be better off checking the wind forecast from somewhere else.
Now, Wednesday the 16th is when things get interesting, but only if you’ve got the skills and the board for it. A big pulse of south swell pushes in on Wednesday morning, showing a solid 10ft from the south. The combined energy is absolutely pumping at 1247, which is strong. The wind is cross-off from the SSW at a stiff 25 mph, so it’ll be clean, but that’s a lot of breeze on tap. By Wednesday afternoon the swell hits 12ft from the south, with wave energy up to 2523. This is big, powerful, and really only one for the experienced crew. The south direction can line up okay here, but with that much juice, you’ll need to pick your peak.
Thursday the 17th keeps the size going with another 10ft on the morning from the south, and the energy is even higher at 2533. The wind stays cross-off from the south at 19 mph, so it stays clean. Thursday afternoon drops off a bit to 8ft from the SSE, but the wind swings cross-shore and it gets a bit messy. Still, the morning of Thursday the 17th is your window if you’re looking for a real slab.
After that, things wind down. By Friday the 18th, there’s a smaller, cleaner morning with 3ft from the south, and light cross-off winds. It’ll be surfable, but nothing to write home about. The real standout to keep an eye on is the following Saturday morning, the 19th. We get a long-period south groundswell, 2ft but the period is a very long 17 seconds. That’s proper groundswell, and with a light westerly offshore at 9 mph, it’ll be glassy. The energy is moderate at 359, but for a point-break setup, that long period can make the lines incredibly clean. It’ll be a super-tidey, organised little swell, and given how long the wait is, it’s a real treat.
After that, it goes back to small, weak, and messy. The morning of Friday the 25th has a bit of a blip with 4ft from the NE and clean cross-off winds, but it’s short period at 6 seconds, so it won’t be all that. And the morning of the 26th, with glassy conditions and small 3ft waves, is nice for a log but the energy’s low.
So, best on offer: Thursday morning the 17th for the big, clean south swell – that’s the one for the experts. And for a more relaxed, long-period treat, Saturday morning the 19th is a real winner for the more refined spots, with that offshore wind. Water temp is about 63°, which is a touch below average for this time of year, so a decent spring suit is the go.
Alright, stay safe, and I’ll catch you down the beach.
– 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.
