The Lowdown
Alright folks, Rusty here. Let’s take a look at what’s in store for The Box over the next couple of weeks.
First off, I gotta be straight with you: this is a tough one. The Box is an advanced, inconsistent spot, and over this whole 16-day stretch, the surf just doesn’t show up in any meaningful way. We’re looking at a long, dry spell. There’s a big gap of nothing from now until around the 21st of August, with only tiny, weak, short-period pulses that are barely making a ripple. The combined wave energy is practically zero for most of the first week, with values like 9 and even 1 on some days—that’s whisper-level stuff. The wind is mostly cross or cross-on, with some glassy mornings on the 14th and 15th, but even then, there’s no swell to ride.
The water temperature on the first surfable morning (10th August) is sitting at 84°F, with an anomaly of 5°F, which is much warmer than normal for this time of year. That’s a real standout detail, but it doesn’t make the waves any better.
The only faint glimmer of something happens late in the window. Around Friday the 21st afternoon, we finally see a little bump in energy: a 3ft swell from the north with a 5-second period, giving us a combined energy of 27. It’s small, onshore, and messy, but it’s something. Saturday the 22nd morning sees a cleaner window with a light offshore wind from the SSW and a 2ft NNE swell, energy at 19. For a spot that’s been dead for over a week, this is the best we’ve got. Still, it’s tiny, inconsistent, and only for the advanced crew who know the break.
If you’re a kite surfer, the beach-and-reef setup might look more interesting on those days with a bit of cross-shore wind, but for a paddle surfer, this is a lean period. The Box rarely breaks well, and this forecast is a perfect example of why. Forecasts can change, so don’t write it off completely, but for now, the board stays in the car.
Rusty, signing off.

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.
