The Lowdown
Alright folks, Rusty here. Let’s have a proper look at what’s on the cards over the next couple of weeks.
Honestly, it’s a bit of a grim start. We’ve got a big, powerful swell coming in, but the wind is just ruining it. There’s nothing worthwhile right now. You’re going to have to be patient. The first decent window doesn’t show up until Friday, 18th September, and even then it’s just okay.
The main event is Wednesday 16th September. A solid 10ft south swell is pushing through, with strong wave energy (1938), but the wind is a cross-off from the SSW at 22 mph, which makes it tricky. By the afternoon it turns cross and messy. This is only for advanced surfers, and honestly, the configuration with the beach and reef setup here is more interesting for kite surfing than paddle surfing. Best to sit this one out.
The swell drops quickly after that. Thursday 17th September morning has a cleaner look with an 8ft SSE swell and a cross-off breeze from the SSW at 12 mph (1142 energy), but the quality is still marginal. Friday 18th Friday morning is the first real chance. The swell drops to a modest 5ft from the south, period 9 seconds, with a light cross-off from the NW at 6 mph. It’s clean and surfable (430 energy). It won’t blow you away, but it’s the best of a bad bunch so far.
The weekend is small. Saturday 19th and Sunday 20th have waist-high waves with clean, light winds in the mornings, but the energy is weak (156 and 196). You could get a fun little session in but nothing to write home about.
Then we hit a long, blank stretch. From Monday 21st right through to Tuesday 29th September, the wind is all wrong – mostly cross-onshore or cross-shore – and the surf quality is poor. A lot of these days have a score you wouldn’t bother looking at. There’s a small bump on Monday 28th with a 5ft swell from the NE, but it’s messy with a strong cross-onshore wind. Not worth it for a paddle.
The only real standout in the whole 16-day window is the very end. Here’s the one to circle: Wednesday 30th September morning. A clean 4ft swell from the NE, period 6 seconds, with a light cross-off from the WNW at 6 mph. Wave energy is solid (252). This is your best bet – a clean, surfable morning with no crowds likely at Bronte Beach. The water temperature is 63°F, which is about normal for this time of year. Get on it early.
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.
