The Lowdown

Alright, Rusty here. Let me break down what's cookin'.

First things first – the next week and a half is pretty much a dead zone. You're lookin' at a solid 8-day stretch where you won't find anything worth paddlin' for, so save your energy. The water's a warm 82°, which is about 2° warmer than average for this time of year – nothin' wild, just a bit above the norm.

The first time you might see a ripple worth a glance is Saturday, August 31st. The morning's got a light offshore breeze and near-glass, but the swell is tiny – just 2ft from the east. The wave energy is weak (141). You could get a few knee-high sliders if you're really itchin', but it's not a day to plan around. The afternoon turns glassy, but it's still only 2ft.

Now, here's the one that's got my attention – but it's a long way out, so keep your fingers crossed. Look at Monday, September 8th. We've got a south swell rollin' in at 4ft with a 13-second period. The wind is blowin' offshore from the NNE, which will keep Big Ben nice and clean. This is a beach and jetty break, and it's inconsistent, so you'll be waitin' for the sets. But when they come, the quality should be there. The combined energy is moderate (595), and the direction lines up well with the break. This is your best chance across the whole 16 days – solid, clean, head-high waves for the experienced crew. Beginners might find it a bit much if it pushes 5ft, but for the rest of us, it's the window to aim for.

Before that, Saturday, September 5th has a pulse of ENE swell at 6ft, but the period is short (9 seconds) and the wind is messy. That one's gonna be choppy and bumpy – more of a kite day than a paddle day. The rest of the second week is just marginal, ordinary stuff with cross-shore breezes and small, weak swell.

Bottom line: the first 8 days are a bust. The standout is that Monday, September 8th at Big Ben. Put it on the radar, but don't hold your breath – long-range forecasts are a gamble.

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.
