The Lowdown
Alright, Rusty here, giving you the lowdown in feet and knots. I've been staring at the charts for The Box and I've got to be straight with you.
The outlook is grim. We're looking at a solid 16 days of nearly nothing. It’s a long, flat spell. There's no real surf on offer at all. The first chance of anything rideable doesn't show up until the tail end of the second week.
The water feels a touch warmer than it should be for this time of year.
Let's walk through it. From Sunday the 6th all the way through to Wednesday morning the 16th, it's a dead zone. You'll see tiny pulses of energy here and there, but nothing over 3ft and it's all weak, short-period junk. The winds are all over the place, mostly onshore or cross-shore.
We get a little sign of life on Thursday the 17th. The morning shows a NE swell around 3ft but with a short period of 5 seconds, so it'll be weak. The wind is light from the NNW, so it'll be cross-shore. By the afternoon, the swell bumps up to 4ft, but the period is still a weak 6 seconds, and the wind switches onshore from the ENE. It’s not going to be any good.
Then on Friday the 18th, we get the one and only chance. The morning is glassy calm with a NE swell of 3ft at a 6 second period. The combined energy is still weak. It's not big, but with the glassy conditions, it will be clean. The Box is an inconsistent spot and this is the only window where it might look half-decent for a longboard.
After that, it's right back to flatness right through to Monday the 21st.
So the only real standout is Friday the 18th morning. The Box is an advanced, inconsistent break and with the light glassy wind, it might be clean enough for the experts to find a couple of ankle-biters. If you are desperate for a paddle, that’s your only shot. Otherwise, the forecast looks like a kite-surfing setup for most of the period with the onshore winds and tiny swell, rather than anything for a proper paddle surfer.
Hang in there.

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.
