The Lowdown
Alright folks, Rusty here with a look at the next couple of weeks for Big Ben. Let’s get straight into it.
First up, the water temp’s sitting at about 77°F which is pretty normal for this time of year – nothing weird going on there. Now, Big Ben is a beach/jetty setup, exposed to swell and best with SE direction, but it’s inconsistent and can get crowded sometimes. The first week and a half? Honestly, pretty grim. From Thursday 16 July right through to Saturday 25 July, it’s all poor surf conditions – chop, cross-onshore winds, and small bumpy waves. There’s a bit of energy around (combined energy values between 139 and 517, mostly moderate), but the winds are never clean. Nothing worth paddling out for. You’d be better off waiting.
Then comes Monday 27 July morning – that’s the one. The swell picks up to 4ft from SSE, period 10 seconds, and the wind goes glassy. Combined energy is 517 (moderate) and the wave comment says expect very good surf conditions. That’s a standout. Clean, fun-sized waves, perfect for a beginner-friendly spot like this. The direction is close to optimum too (SE is ideal, SSE is just a tick off). The afternoon goes cross-onshore again, so hit that early window. Crowds are possible, but with it being inconsistent and the forecast poor for so long, you might have it to yourself.
After that, Tuesday 28 July afternoon offers a bigger 5ft from S with moderate cross-shore wind, but it’s only rated marginal – probably lumpy with that breeze. Still, it’s a bit of size and energy (714, strong). If you’re keen, maybe give it a look, but don’t expect perfection. The rest of the week into 31 July is back to poor – cross-shore winds, moderate to fresh breezes, and choppy conditions. Even though a few swells have long periods (13-16 seconds), the wind ruins it. The 30th has a 2ft ESE swell with 16-second period, but wind is fresh cross-shore– lumpy as hell. That’s not surfable for a beginner.
So bottom line: hold out for Monday 27th morning. That’s your best shot. Everything else is either flat, messy, or just not worth the drive. Keep an eye on the forecasts though – it’s been inconsistent, so it could turn around. But based on what I see now, that Monday morning is the only true standout.
Rusty.

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.
