The Lowdown
Alright folks, Rusty here. Let’s have a look at what’s on offer.
Honestly, I gotta be straight with you – the next 16 days look like a write-off for The Box. That’s a tough pill to swallow, but I’m looking at the charts and there’s just nothing doing. The whole run is practically flat and the few ripples that show up are blown out or tiny. From Saturday the 5th right through to Sunday the 20th of September, I can’t recommend a single session. That’s more than two weeks of bummers.
We’ve got a stretch of clear skies and some light winds, especially on the 7th of September, Monday morning, when it’s glassy. But with no swell, it’s a lake. The water’s a touch warmer than normal for this time of year, sitting at 80°, but that’s about the only highlight.
The only time we see any pulse at all is around the 10th of September, Thursday morning. The combined swell energy hits 200 (moderate), with a 4 ft swell from the NE, but it’s a short period of 8 seconds and the wind is a cross-onshore at 12 mph. It’s messy and honestly, not worth paddling out for. The Box is inconsistent and advanced only, so it needs a proper window. This ain’t it.
It’s a blank run, plain and simple. Sometimes that’s just how it goes in this spot. Forecasts can change, but right now, I’d leave the boards 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.
