The Lowdown
G’day, it’s Rusty here. Let’s be straight with you: the next couple of weeks around Bronte Beach are going to test your patience. We’ve got a long stretch of ordinary, choppy, cross-onshore slop ahead, with a couple of proper windows of clean swell buried in there if you’re willing to hunt for them.
First things first, the water temp is sitting about average for this time of year, nothing weird going on there. And to be honest, for the first few days, the surf is pretty much a write-off. Sunday the 13th and Monday the 14th have some south swell pushing in, but it’s weak and the wind is all over it. Sunday arvo gets a fresh 30 km/h NE cross-onshore making it lumpy, and Monday’s not much better. Small, messy, and not worth paddling out for unless you just want to get wet.
Tuesday the 15th stays poor. There’s a brief bit of clean surf in the morning with a SSW cross-off, but the swell drops right off. The energy is weak (66) and you’re looking at ankle-biters. The arvo is a write-off again with fresh cross-shore wind.
Now, here’s the big one. Wednesday the 16th and Thursday the 17th, the ocean wakes up. We’re talking a solid south groundswell building to 10 ft on Wednesday morning, jumping to 12 ft by the arvo, and holding around 12 ft Thursday morning. The energy readings are huge – 1246, 2574, 2006 – this is strong, powerful stuff. The wind is cross-off and clean, so the faces will be lined up. But let’s not kid ourselves: this is well over 8 ft, so it’s strictly for the experts. Bronte is a beach and reef set-up, and with that much juice, the currents and closeouts will be serious. Beginners and even most intermediates should stay on the sand. The period is around 9-10 seconds, so it’s punchy but not crazy long.
By Friday the 18th, the swell drops back to a more manageable 4 ft in the morning. The wind swings light NW cross-off, and it’s clean. This is your best chance for a decent session in the first week. It’s not huge, but the energy is moderate (310) and the conditions will be good. Friday arvo gets messy again with a NE cross-on, so get out early.
Saturday the 19th is interesting. Morning has a clean WNW offshore wind and a 3 ft ESE swell with an 11-second period. That longer period means it’ll have a bit more push to it. It’s a small day, but clean and glassy. A good one for a longboard or a funboard.
Then we hit a flat spell. Sunday the 20th and Monday the 21st are poor, with tiny swell and messy winds. The energy drops right off (down to 42 and 34), so you’re looking at flat burgers. Tuesday the 22nd brings some size back – 8-8 ft – but it’s coming with SE cross-onshore winds and rain. It’s junky, lumpy, and not worth the hassle. Keep the board in the car.
Wednesday the 23rd and Thursday the 24th stay in the poor-to-ordinary bracket. We’ve got 4 ft south swell but it’s onshore and choppy, with rain around. The energy is moderate (540, 414) but the quality just isn’t there.
Now, Friday the 25th. The morning is clean – dead glassy with a light N breeze. But the swell is tiny. 2 ft at best, with an 11-second period. The energy is weak (79). It’s surfable, but you’ll be fighting for every ripple. Honestly, it’s a “if you’re desperate” kind of paddle.
The real standout of the whole window is Saturday the 26th morning. The forecast shows a fresh 5 ft NE swell with a light NNW cross-off wind, and the energy is pushing moderate (377). The conditions are clean. This is the one to circle on the calendar. The swell direction is a bit off from the optimum, but the clean conditions and rideable size make it the pick of the fortnight. It’s a Saturday, so expect some company, but the quality should make up for it. This one’s a promising, but as it’s over a week away, treat it as a possibility rather than a guarantee.
Sunday the 27th drops back down to mush. And by Monday the 28th, we’ve got another 7 ft south swell on the way with light cross-onshore wind and some clouds. The energy is strong (815), but the wind will likely chop it up. It could be another expert-only session if it cleans up, but the outlook is marginal.
So, bottom line: the first week is mostly a grind. Wednesday and Thursday are big and gnarly – for the charger crew only. The true standout is Saturday the 26th morning – clean and fun-sized. The good news is Bronte is fairly consistent, so even after a blank stretch, it usually turns back on. Just keep an eye on the wind.
Rusty out.

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.
