The Lowdown
Alright folks, Rusty here. Let’s see what’s in the water for the next couple of weeks.
First thing, it’s dead flat. We’ve got a solid week of nothing. The first time you’ll even see a ripple is Friday the 11th of September. The Box is a tricky, inconsistent wave, and a run like this isn’t unusual for the area. It won’t stay poor forever, but for now, it’s a waiting game.
The only real standout is that Friday morning, the 11th. The Box is expecting a tiny 2ft swell from the NE, with a period of 8 seconds. The total energy in the water is weak (62). The big win is the wind — it’s glassy, coming from the W at just 3 mph. That’s going to make it dead clean, which is a rare treat. The water is sitting at 79°, about a degree warmer than usual for this time of year. Just remember, this is an advanced wave that’s inconsistent, and it *can* get a few heads on it sometimes.
After that, it’s back to the flat. Saturday the 12th and Sunday the 13th are a waste of time, just tiny bumps and chop. The rest of the forecast through the 18th is a total wipeout — no swell, no energy. For a beach and reef setup like this, with that tiny surf and some cross-shore winds, you’d honestly have a better time on a kite.
Keep checking back, but don’t hold your breath.
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.
