The Lowdown

G'day, Rusty here. Let's have a look at what's coming up for Big Ben.

Right off the bat, the next few days are looking pretty flat and ordinary. We've got a long stretch of small, messy waves that aren't really worth paddling out for. The water's sitting at a warm 82°, which is about what you'd expect for this time of year.

The first real glimmer of hope doesn't show up until Sunday the 30th of August. It's a small window, but Sunday afternoon could be a sneaky one. The swell is a tiny 2 feet from the east with a 11-second period, and the combined energy is weak (140). The real story here is the wind: it's going glassy. That means the surface will be like a mirror. It's not going to be a wave of consequence, but if you're desperate for a clean, small-wave session, this is your only chance.

Monday the 31st of August morning also looks okay. The swell is still only 2 feet from the east, but the wind is a clean cross-offshore from the NNE. The energy is still low (193), but it'll be surfable. Again, it's a small wave day, not a standout.

The real action, and the only true standout in this entire 16-day window, is happening on Wednesday the 9th of September. The morning is looking prime. We've got a 5-foot south swell with a decent 11-second period, and the combined energy is moderate (627). The wind is a light cross-offshore from the north, which will keep the faces clean. For a beach/jetty setup, this is about as good as it gets. The waves will have some punch, but won't be too big for a confident beginner. The afternoon session on the 9th also looks good, with glassy conditions and a 5-foot south swell, but the morning is the pick.

As for the rest of the first week of September, there's a significant swell pulse on the 2nd and 3rd, with waves over 7 feet, but the wind is all over the place, mostly cross or cross-onshore, making it a choppy mess. That's more of a kite-surfing setup than a clean paddle session.

The run from the 5th of September has some small, cleanish windows, but nothing that compares to the 9th. The last few days of the outlook, from the 8th of September and beyond, show a lot of wind and stormy conditions, so the 9th is your clear target.

So, to sum it up: wait for the glass on the 30th of August for a novelty session, or lock in the morning of Wednesday the 9th of September for the best waves of the outlook. There's not much else that's worth getting excited about.

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.
