The Lowdown
G’day, Rusty here. Let’s be straight with you – if you’re looking for a wave at The Box over the next sixteen days, you’re in for a long wait. This setup just isn’t getting any love from the swell window. We’ve got a dry spell that stretches from Saturday the 29th of August all the way through to Wednesday the 9th of September with barely a ripple worth paddling for. That’s nearly two weeks of flat or junk.
Alright, let’s run through it. Saturday the 29th kicks off with a weak 1.0 ft of swell from the NE, period a snappy 4 seconds, and combined energy a pathetic 4. Wind is cross-off from the NW at 15 km/h, so it’s clean, but there’s no power. Water temp’s sitting at 80°, which is a touch warmer than normal for this time of year – a degree and a bit above average, so it’s a nice bath, but no waves to enjoy it. Sunday the 30th goes glassy in the morning but with 0.3 ft, it’s a lake. Monday the 31st is flat as a tack. Tuesday, Wednesday, all the way into early September – we’re talking tiny wobbles, mostly under 2 ft, with onshore or cross winds messing up what little there is. The Box is inconsistent at the best of times, and this stretch proves it.
Then on Wednesday the 9th of September afternoon, there’s a lift: 4 ft from the ENE, period 6 seconds, combined energy hits 124 – that’s moderate energy, finally something with a bit of grunt. But the wind is straight onshore from the ENE at 20 km/h, and it’s moderate cross-onshore and choppy. Surf quality is still rated poor. It’s not worth a paddle for a beginner or a pro.
Thursday the 10th of September cleans up with a cross-off southerly at 25 km/h, but the swell drops back to 2 ft and 2 ft, energy 45 and 43. Clean but tiny. Friday the 11th of September morning actually gives us offshore wind from the SW at 15 km/h – that’s gentle offshore and clean. Swell is only 1 ft from the NE, period 7 seconds, energy 17. You could get a longboard out for a knee-high slide, but it’s not a standout.
Honestly, there is no standout in this outlook. The best on offer is that Friday the 11th morning: offshore, clean, tiny. If you’re desperate, you could pop out for a mellow session. But for anyone hoping for a proper wave, this is a blank run. The Box rarely delivers in this pattern – it’s more normal for the area to see long flat spells. Forecasts can change, but right now, I’d leave the board in the car.

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.
