The Lowdown
Right, let’s have a look at The Box. It’s a beach and reef setup in The-Box, and I’m not gonna sugarcoat it—there’s nothing really happening for the next couple of weeks. The whole 16-day window is a bit of a washout for paddle surfing. We’ve got a big gap starting now with no real surf to speak of until the tail end of the period, and even then, it’s marginal at best.
From Thursday 13 August right through to Monday 24 August, it’s mostly flat or tiny, messy, and weak. The combined swell energy barely gets into double digits most days, often sitting between 0 and 27 (weak), with a few blips up to 29 but still weak. Winds are mixed—sometimes clean, sometimes choppy—but the swell is just too small to care about. A glassy morning on Saturday 15 August sounds nice, but with no swell, it’s just a flat paddle.
Things start to show a pulse on Monday 24 August afternoon, with a little bump to 3 ft from the NNE, period around 5 seconds, and clean cross-off wind. Combined energy hits 58, still only moderate. Not exactly firing, but it’s the first sign of life. The standout, if you can call it that, comes on Wednesday 26 August afternoon, when we see 4 ft from the NE, period 5 seconds, with light cross-onshore breeze. Combined energy reads 93, moderate. For The Box, that’s about as good as it gets in this run. It’s not big, but the wind is light. Thursday 27 August morning has a 2 ft NE swell with a 7-second period and light offshore, clean. That one looks okay for a quiet session.
Water temp earlier in the period was 84°, which is much warmer than normal for the time of year—about 5° above average. That’s a notable warmth.
The Box is an advanced spot and inconsistent, which is a tough combo. When it does show up, you need the right direction and wind. ENE is the optimum swell direction here, and most of the small pulses are from the NE or NNE, so not a perfect match. Swell heights never crack 5 ft, so it’s not too big, but the short periods mean the waves lack punch.
Honestly, if you’re a surfer, you’ll be twiddling your thumbs most of the fortnight. The best you get is Wednesday 26 August afternoon—that 4 ft with light wind is the pick. And maybe Thursday 27 August morning for a clean, small option. Everything else is a bust.

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.
