The Lowdown
Right, gather 'round. Rusty here. Let’s have a look at what’s on offer for The Box.
Straight up, the next week and a half is a write-off. I’m not seeing any surf worth paddling out for. The energy is just flat, with combined swell energy readings barely cracking single digits (3) on the 12th, and most days sitting at zero. Conditions are messy with cross-shore and onshore winds, and the water is an incredibly warm 83.5° – that’s a massive 4.9° warmer than usual for this time of year, which feels weird, but with no waves, it’s just a bath.
The first real glimmer of hope doesn’t show until Monday the 24th of August. Monday morning sees a jump in the swell energy to a moderate 183 (combined energy), with a 4.6ft swell from the NNE. The wind is a light cross-offshore breeze from the WNW, which will keep the surface clean. The period is a short 7 seconds, so it’ll be a bit weak and won’t have the punch of a proper groundswell, but it’s the only window that looks surfable. The Box is a beach and reef setup, and it’s an advanced spot that’s inconsistent, so it’ll take a bit of luck to line up. With the swell direction being NNE, it’s not the optimum ENE direction, but it’s the best we’ve got.
After that, it drops back to tiny stuff for the rest of the forecast. Honestly, if you’re desperate, that Monday morning is your only chance. The rest of the 16 days is a flat, blank run. That’s just how it goes sometimes.

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.
