The Lowdown
Alright, let's be straight with you. I've been looking at The Box for this whole 16-day stretch, and honestly, it's a wasteland out there. We're looking at a solid week-long dry spell at the start with absolutely nothing on offer. Just flat, poor conditions. Don't get too wound up about it, but maybe plan for something else.
The first few days are a total write-off. Tuesday and Wednesday are showing tiny, weak swell with poor conditions. The wind is all over the place, mostly cross-shore, just making it a mess. There's no power, no push. The combined energy is almost nothing, single digits. It's not even worth looking at.
We get a little hiccup of swell on Saturday the 22nd, but it's still junky. The Box is such a picky wave, and with only 2ft of swell and a moderate cross-shore wind, it's not gonna break with any kind of shape. Then Sunday the 23rd gives us a 2ft bump from the NE with lighter winds, but the energy is still weak. It's just not enough to get this place doing its thing.
Monday the 24th morning is glassy, but there's zero swell. Completely flat. Then Tuesday the 25th, the swell picks up a bit to 4ft, but it's from the NE with a cross-onshore wind. That's gonna be choppy and messy. The energy jumps to a moderate 76, but it's not the clean, groomed swell this spot needs.
The only thing that might get you a little excited is Sunday the 30th. We see a 4ft swell from the ESE, which is closer to the optimum ENE direction, and the energy bumps up to 91. But the wind is a fresh cross-onshore at 19 mph. That's going to make it pretty rough and lumpy. Not ideal, but in this dry spell, it might be the only chance you have to get wet.
I can't give you one true standout in this whole run. The conditions just never line up for The Box. It needs a decent, clean swell, and we just aren't getting it. The water temp is about average for this time of year. It's just a waiting game, I guess. Forecasts can change, but as it stands right now, you'd be better off finding a lake or something.

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.
