The Lowdown
G’day, Rusty here. Let’s cut to it. The next couple of weeks are pretty bleak for The Box. We’re looking at a long stretch of flat, small, and messy conditions, with barely a wave worth paddling for until the very end of the period. You’re gonna have to be patient, and even then, it’s not going to be anything special.
The first week is essentially a write-off. From Sunday the 16th right through to the 22nd, there’s no surf on offer at all. The swell energy is sitting at zero, and when there’s a ripple, it’s either too small or blown out by onshores or cross-shore winds. There’s a clean moment on the 21st with a bit of glass, but there’s nothing to ride. For a spot like The Box, which is pretty inconsistent anyway, this kind of blank run is a real kick in the teeth.
We finally see a glimmer of life on Sunday the 24th. The swell picks up a touch to 3ft from the NNE, with energy starting to build to 31. The morning wind is light and cross-off, keeping it clean. It’s not big, but it’s the first real sign of something. This is a beach and reef set-up, and that NNE direction is okay, but it’s nothing to write home about. The next day, the swell fades back down again.
The standout, for what it’s worth, comes at the very end of the window, on Sunday the 30th of August. The swell jumps to 5.6ft from the NNE, and the combined energy is a solid 323, which is a proper pulse of energy for this spot. The morning has a moderate cross-off breeze, holding it together. It’s not going to be huge, but it’s the best size we’ve seen in a fortnight. The afternoon drops a bit to 4.3ft but the wind goes light, making it cleaner. Keep in mind, The Box can be a bit of a handful – it’s an advanced wave and inconsistent, so you’ve got to be on your game. For the beginners out there, this is over 5ft, so it’s probably too much.
Following that, Monday the 31st sees the swell drop back down to 2.3ft with a 9-second period, and the energy is gone. So, a long, quiet run, one brief pulse at the end, and then it’s flat again. Don’t get your hopes up too high, but that Sunday the 30th is the one to maybe keep an eye on.

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