The Lowdown
G’day, I’m Rusty, and I’ve been staring at the charts for Big Ben, and I gotta be straight with you – it’s a real tough stretch ahead. The forecast is a long, dry spell with hardly anything worth paddling out for.
Alright, let’s get into it. Right now, we’re looking at a whole lot of nothing. The first solid chance at a wave doesn’t even show up until Thursday, 30 July, and even then, it’s barely a whisper. The swell is only 1ft from the E with a period of 9 seconds, and the water’s still a pleasant 80°, which is about normal for this time of year. But the real kicker is the wind – a light cross-offshore from the NNE, which is actually keeping things clean. The combined energy is a measly 62, so it’s weak. I’m telling you, it’s surfable but very ordinary. You’d be scratching for scraps.
Then we wait again. The next bit of interest isn’t until Saturday, 1 August, when the swell starts to build. We get a 6ft ESE groundswell with a long 17-second period, and the combined energy jumps to 1799 – that’s moderate. The wind is a gentle cross-shore from the NE, which is alright, but the conditions are described as marginal. It’s a bit of a tease, really.
The real standout, if you can call it that, is Sunday, 2 August. The swell settles at 8ft from the ESE with a 16-17 second period, which is a serious groundswell. The energy is strong at 3354-3600. The wind is clean, especially on the Sunday morning with a cross-offshore from the NNE. Now, 8ft is getting into expert territory, and with that long period, it’s going to be fat and straight at a beach/jetty setup like Big Ben. It might be better suited for a point break or reef. So, for the experienced crew, it could be a big, powerful, but tricky wave. For everyone else, it’s a session to watch from the sand.
The very end of the run, on Wednesday, 5 August, has a 5ft swell from the E with a 13-second period, but the wind is mostly cross or onshore, and the energy is only 667. It’s not looking great.
Honestly, this 16-day window is a drought. There are long gaps with no recommendations at all. If you’re desperate, the clean wind on Thursday, 30 July, makes it the only real “maybe” for a beginner-friendly paddle, but the swell is tiny. For the more experienced, Sunday, 2 August, is the biggest, most powerful offering, but it’s a real handful and the conditions are marginal. The forecasts can change, but as it stands, this is a quiet period for Big Ben.

Information about the Big Ben Surf forecast
The above surf forecast table for Big Ben provides essential information for determining whether the surfing conditions will be good over the next 16 days. A general guide to surfing at Big Ben can be found by selecting the local surf guide option on the grey menu. Our Big Ben 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 (Big Ben) 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 Big Ben 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.
