The Lowdown
Alright, let’s get this straight – the 16-day window for The Box is a tough one. We’re looking at a long stretch of nothing, or next to nothing, with a couple of flickers of hope way down the line. For the first week and a half, it’s a desert. The water temp is sitting at a very unusual 84°, which is much warmer than average for this time of year, but that’s not going to make up for the lack of rideable waves.
From Saturday the 8th of August right through until the morning of Thursday the 21st of August, the surf is either non-existent or so small and weak it’s not worth paddling out for. The combined swell energy is often in the single digits or low teens, with tiny waves and poor conditions. The wind is mostly cross or onshore, which doesn’t help. It’s a bleak run.
The first real sniff of something happens on the morning of Friday the 21st of August. We’ve got a glassy, near-calm morning with a 2ft swell from the NE, with a period of 10 seconds. That’s a moderate energy groundswell (105). The conditions are clean, but the waves are still pretty ordinary. The afternoon picks up a bit more energy with a 4ft swell from the same NE direction, period still 10 seconds, and the combined energy jumps to 314 (moderate). The wind goes cross-shore, so there’s a bit of chop, but it’s the most size we’ve seen all forecast. The Box is an advanced, inconsistent break, so this kind of swell might have a few fun ones for the experts, but it’s not a standout.
Then on Saturday the 22nd, the morning has a 2ft NE swell, period 8 seconds, with clean conditions and a light cross-offshore wind. The energy is weak (54). It’s surfable, but barely.
To be honest, there’s no real standout in this whole forecast. The best call is the Friday afternoon, the 21st of August, with that 4ft NE swell. It’s a bit of a letdown, but that’s the way it goes sometimes. Forecasts can change, so keep an eye on it.

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.
