The Lowdown
Alright, let’s talk about Bronte Beach in feet and miles per hour. This 16-day window is a frustrating one for anyone who isn’t an expert paddling into big, unpredictable stuff. The water temp is about 63°, which is pretty normal for this time of year.
Tuesday is a total dud. Swell is tiny at 2 ft, cross-shore wind, and the combined wave energy is only 67—barely a ripple. Not worth a look.
Wednesday the 16th suddenly fires up, but it’s for experts only. Morning sees 10 ft southerly swell, period 10 seconds, and the combined energy rockets to 2024—that's serious power. Winds are cross-off and clean. That’s the best-looking session for the strong paddlers. It gets even bigger in the afternoon, hitting 12 ft, but that’s even more gnarly for a spot that’s inconsistent.
Thursday the 17th morning drops to 8 ft with clean cross-off wind and energy at 1042. Still too big for beginners, and crowds can show up. Afternoon gets messy with onshore wind.
Friday the 18th morning is the best for everyone else: 5 ft southerly swell, period 9 seconds, combined energy 411—moderate—with light cross-off wind. Clean and doable. But after lunch, the wind turns onshore and kills it.
From there, it’s a long, bleak stretch. Most days see small swell, choppy conditions, or onshore winds. There’s a stretch from the 19th through the 25th that’s mostly poor.
Thursday the 26th morning offers a small pulse: 6 ft from the northeast, short period at 8 seconds, combined energy 574. Wind is light but cross-on, so it’s only marginal. It’s the least bad option in a disappointing second week.
Bottom line: if you’re an expert, hit Wednesday the 16th morning for size and power. If you want a clean, manageable wave, Friday the 18th morning is your best bet. Everything else is either too weak, too windy, or just plain bad. Bronte isn’t playing ball this time. Forecasts change, but right now, it’s a waiting game.

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.
