The Lowdown
Alright, this is a tough one to call. The Box is an advanced spot, a beach and reef setup that’s inconsistent and can get crowded. Over the next 16 days, the surf just doesn’t fire up. The water is sitting at 80°F with a positive anomaly of 3°F, meaning it’s a touch warmer than average for this time of year, but that’s small comfort when there’s next to nothing to ride.
From now through to the 9th of September, it’s basically a flat spell. The combined energy is zero for most of the first week, with tiny dribbles of swell that never get above 2ft. The wind is all over the place, sometimes glassy, but the swell just isn’t there. There’s a long gap of poor surf conditions with no real recommendations.
The first real hint of life shows up on the morning of Thursday, the 10th of September. The Box picks up a small 3ft swell from the NE with an 8-second period, and the combined energy climbs to 126 (moderate). The wind is glassy, which is a major positive for clean conditions. It’s surfable, but the wave comment says “very ordinary conditions.” It’s not a standout, just the best of a bad bunch.
The only other moment worth a look is the afternoon of the 10th, but the wind swings to 25 mph from the S, cross-off, which will clean it up, but the swell drops to 3ft from the ESE with a short 6-second period, and the energy falls to 96 (weak). After that, it’s back to small, choppy, onshore junk for the rest of the forecast period.
For a spot that’s already inconsistent, this is a blank run. The Box stays quiet, and there’s nothing here that’ll get the heart racing. The only real standout, if you can call it that, is the Thursday morning on the 10th of September – glassy, knee-high, but at least you might get a clean little wave if you’re patient.

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.
