The Lowdown
Alright folks, Rusty here. Let’s have a look at what Bronte Beach has in store for us over the next couple of weeks. Straight up, it’s a bit of a mixed bag with some real potential if you time it right.
The opening of the period is pretty average. Tuesday morning (15th September) we’ve got tiny 2ft surf from the NE, weak as anything with only 64 (weak energy) behind it. The wind is cross-off though, so it’s clean, but it’s not worth getting wet for. Tuesday afternoon gets worse with a cross-shore mess, so give it a miss.
Things get a lot more interesting on Wednesday morning (16th September). A solid 10ft S swell rolls in with a period of 10 seconds, and the energy is massive at 1712 (very strong). This is proper groundswell, and at this size it’s for advanced surfers only. The wind is cross-off from the SSW, so it will be clean. This is a standout if you’ve got the skills. By the afternoon, the wind swings onshore and it gets messy.
Thursday morning (17th September) drops to 8ft from the SSE, still a decent size, with a moderate 1042 energy. Clean cross-off wind again, making it a good option for experienced surfers. The afternoon sees an onshore breeze, but the swell hangs in there around 6ft.
Friday morning (18th September) is a real gem. The swell drops to a more friendly 4ft from the S, but the wind is near calm, a light NNW breeze at 5 km/h giving you glassy, cross-off conditions. The energy is a moderate 350. This will be clean, lined-up, and a joy to surf for all levels. Afternoon gets chopped up by a cross-on wind.
The weekend (19th and 20th September) drops right off. Tiny 3ft on Saturday morning, and by Sunday morning we’re down to 2ft with barely any energy (43). A real lull, and not worth paddling out.
The following week (21st to 25th September) is dominated by poor conditions. The wind is mostly cross-onshore or onshore, and the swell is inconsistent or short-period junk. There’s a 4ft S swell on Monday morning (21st) with a long 12-second period, but it’s ruined by a cross-shore wind. The energy is moderate at 504, but it’s just not clean.
Finally, we get a light at the end of the tunnel. Monday morning (28th September) and Monday afternoon (28th September) both look promising. The swell is 4ft to 3ft from the ESE, with light NNW winds and even offshore WNW winds in the afternoon. The energy is moderate (230-249), and the wind will have it clean. This is your second standout window for a proper session.
Best on offer: Wednesday morning (16th September) for the big, powerful 10ft S swell with clean cross-off wind – that’s the one for the charger. For the more everyday surfer, Friday morning (18th September) with the glassy 4ft swell is the pick of the bunch.
Water temp: It’s about average for this time of year, nothing unusual to report.
Stay safe out there, and don't be a kook.
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.
