The Lowdown

Alright folks, Rusty here. Let's have a look at what's on the cards for Big Ben over the next couple of weeks.

Right off the bat, I gotta be honest with you – it's a tough stretch ahead. We're looking at a real flat spell to kick things off, with hardly anything worth paddling out for. The first week is grim. There’s a bit of small swell around, but the wind just won't play ball, leaving the conditions messy and choppy. It’s one of those periods where you’re better off waxing your board and waiting.

The only real standout in this whole 16-day window arrives on Thursday, September 10th. We’ve got a solid pulse of swell, but it’s a tricky one. The combined wave energy is strong, hitting up to (1695) on the Thursday morning. That’s a lot of water moving. We're talking 8 ft of swell from the S, which is expert territory – way too much for beginners. The period is 10 seconds, so it's got some juice but it's not the long, drawn-out groundswell you’d hope for. The bigger issue is the wind, which is forecast as a moderate cross-shore. It’s not going to be perfect, but it will be surfable for the experienced crew who know how to handle a bit of chop. It's the biggest energy we see, but it comes with a serious health warning.

Before that, there’s a brief moment on the afternoon of Sunday, August 30th that deserves a mention. The swell is tiny, just 2 ft from the E, but the wind goes glassy. It’s clean as a whistle. The energy is weak (108), so you won't be getting barreled, but for a longboard or a foiler, that’s a beautiful little window. It’s the cleanest the water will be all outlook.

Looking further out, the second week from September 7th onwards is a constant battle with fresh cross-shore winds. The swell tries to pick up, but it’s mostly messy. There’s a bit of a pulse around the 9th, but a near-gale cross-onshore wind and close to 7 ft swell will blow it out completely. Kite surfers might get a kick out of that wind and chop, but for paddle surfing, it’s a write-off.

So, to sum it up: keep your eyes on Thursday, September 10th if you're an expert and don't mind a bit of cross-shore chaos. Or, get the log out for a glassy but tiny session on the afternoon of Sunday, August 30th. Everything else is a whole lot of nothing or a whole lot of wind.

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.
