The Lowdown
Hey, Rusty here. Got the scoop on the local surf over the next two weeks. Honestly, it's a bit of a slow shuffle for a while. There's nothing really jumping out at us in the first week; it's all a bit weak and messy. But if you can be patient, there's light at the end of the tunnel.
Water temp is 62°, which is about 2 degrees cooler than you'd normally expect for this time of year. A little brisk, so don't forget a good wetsuit.
We finally get a proper chance on Monday morning, August 27th. The wind will be light, offshore from the southwest, meaning clean lines at Bronte Beach. We'll have a 4ft swell from the east-northeast with a short 7-second period. The wave energy is moderate (270), but the clean conditions make it a worthwhile paddle for a few small but tidy waves.
Now, the real highlight is saved for Sunday morning, August 30th. This is the day to get excited about. Bronte Beach is looking at a stunning, glassy morning with no wind at all. The swell bumps up to a solid 6ft from the south with a solid 10-second period. Combined wave energy is cranking at 638 – that is strong. This is going to be the best quality surf of the whole forecast. It’s sizeable enough that it’s best left to the more experienced surfers, but if it stays that clean, you'll be in for a treat. Keep in mind it's a beach and reef, and a longer period south swell can sometimes hold its line and throw out a bit of a wall.
Outside of that, you're looking at scraps. The mornings of Tuesday, August 19th and Thursday, August 21st have clean but tiny waves – barely 2ft. Not worth rushing for. Thursday, August 28th and Friday, August 29th have some small shoulder-high swell but the winds aren't in our favor on the afternoons. The start of September looks like a flat spell again.
Here’s the deal: the first week is nearly a total loss. Do yourself a favor and aim for that Sunday, August 30th at Bronte. That’s the one.
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.
