The Lowdown
Alright, Rusty here. Let’s be straight up about it.
Looking at the whole 16-day window, honestly, it’s a pretty bleak run for The Box. The waves are tiny, the wind is mostly messy, and there’s nothing really worth paddling out for. Most of the time, you’re looking at junk. There’s a long stretch from now, starting Wednesday, September 16th, all the way through to Monday, September 21st with just flat, or near-flat, garbage. It’s a tough start.
The only day that even gets close to halfway decent is on Wednesday, the 23rd. We finally see a pulse of energy come through in the morning, with a NE swell of 4 ft, and the combined swell energy hits 118 (moderate energy). That’s the standout in this whole forecast, but it’s not worth getting too excited about. The wind is cross-shore from the north at 15 km/h. It’s for advanced surfers only. With that swell direction from the ENE and the break’s optimum being ENE, it’s a rare moment where the angles actually line up. The Box is inconsistent so when it does get this sort of swell, it can be a bit of a waiting game.
After that, it’s back to small, weak surf. The rest of the run from September 24th on is just tiny waves, mostly under 2 ft, with cross-onshore or side-off winds. The water temperature on the 16th is 79°, which is a touch warmer than normal for this time of year, not that you’ll need a wetsuit for the flat spell.
So, best bet: Wednesday morning, September 23rd. It’s not a classic, but it’s the only thing on the menu. For the rest, keep the board in the car and wait.
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.
