The Lowdown
Alright folks, Rusty here. Let’s get into it. Looks like we’re in for a quiet stretch at The Box. The overall pattern is one of very small, weak energy across the whole 16-day window. There’s a long gap of poor conditions right from the start, with nothing really worth paddling out for until the very end of the period.
The first real glimmer of anything surfable comes on Sunday, September 6th. That’s over a week away, so we’ve got a solid gap of about 10 days with nothing on offer. The Box is an advanced, inconsistent spot that rarely offers up good waves, and this run is a classic example of that.
On Sunday the 6th, we finally see a pulse of 3ft swell from the ESE, with a period of 7 seconds. The combined energy is still weak at 66, but it’s the best we get. The morning is looking glassy – calm winds, no chop – which is a major positive for a spot that’s a beach and reef setup. The Box is fairly exposed to swell and likes an ENE direction, so this ESE swell is a bit off its optimum, but it’s something. The water temperature is about average for this time of year, nothing unusual there.
Given the size is under 5ft, it’s fine for most surfers, but the inconsistency means you’ll be waiting around. The Box is often crowded, so expect company if you do go. For the rest of the period, we’re looking at tiny, poorly aligned swells, mostly under 2ft, with weak energy readings often in the single digits. The wind is often cross or cross-off, which keeps it clean, but there’s just no power. The setup is more interesting for kite surfing than paddle surfing during those flat spells.
So, the standout – and really the only option – is the morning of Sunday, September 6th. Low expectations, glassy conditions, and a tiny bit of ESE swell. That’s your best bet, but it’s a long way off.
Rusty.

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.
