The Lowdown
Alright folks, Rusty here. Let's talk about what's on the menu at The Box.
Honestly, looking at the next couple of weeks, it’s a bit of a flat spell to start. We’re looking at a solid gap of poor surf conditions from now all the way through to the end of the first week of September. Plenty of small, weak waves and zero energy for most of that time. Don't bother checking the cam until we get into the new month.
For the first real sniff of anything worthwhile, you’ll need to wait until Thursday the 3rd of September. That morning we start to see a push of 5ft swell from the NE, but it’s coming with a short 5-second period and a mess of cross-shore wind. The combined energy kicks up to a moderate 110, but the conditions are still choppy and poor. The afternoon repeats the same story with a touch more size but the same messy cross-shore chop.
Now, Friday the 4th of September is our standout window. Early morning is where it’s at. We’ve got 6ft of NE swell filtering in with a better 8-second period. That’s pushing into solid, moderate wave energy (314) and with the wind going completely glassy – dead calm – it’s going to be clean as a whistle. This is definitely one for the experienced crew, though; 6ft at The Box can get a bit of punch. The afternoon sees a light cross-onshore kick up, so don't expect the same quality.
You’ll see the weekend of the 5th drops off again quickly, back to those tiny, weak conditions.
So in a nutshell: it’s a long wait with nothing doing until the 3rd, and then a single, very promising glassy morning on the 4th of September. Get on it early if you can handle it.
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.
