The Lowdown
Righto, let's get amongst it. This is a tough one to write, I'm not gonna lie. Lookin' at the 16-day window for The Box, and honestly, it's a bit of a sad story. The Box is a beach and reef setup, and it's normally an advanced spot, but it's inconsistent and we just don't have any real swell on the cards.
The forecast kicks off on Wednesday morning, August 19th, with a tiny 0.3 ft push from the NE, but the water temp is a weird 84°, which is a massive 6° warmer than normal for this time of year. That's a very unusual anomaly. The wind is offshore SW at 9 mph, but with that swell it's just a flat, clean lake.
We get a long stretch of nothing. From that Wednesday right through to the end of August, we're looking at gaps of days with zero recommendations. The swell barely tickles above 2 ft, the combined energy hangs around the 20s (weak energy), and the wind is all over the shop. Thursday morning the 20th has a tiny 0.7 ft NNE swell, but it's cross-shore and messy. Saturday the 22nd arvo sees a 2 ft NE swell, 21 (weak energy), but it's cross-onshore and choppy.
The first half of the last week of August is just as average. There's a tiny 2 ft NE swell on Wednesday the 26th morning with glassy conditions, but the energy is only 30 (weak). That's as close to a highlight as we get, and it's still a dud.
The only window that even gets a sniff of something is Thursday the 3rd of September. The morning session has a 2 ft NE swell with an 8-second period, combined energy of 55 (still weak), and it's glassy. The report calls it "surfable waves but very ordinary conditions." That's the best we've got, and it's ordinary. The Box is an advanced break, so tiny waves with that period are just not gonna do anything for the crew that usually rides here.
Honestly, with the swell being so small, the wind frequently cross or onshore, and the energy levels so weak, this setup looks more interesting for a kite surfer than a paddle surfer on most of these days. The Box is a tough spot to get firing, and it's just not happening this forecast period.

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.
