The Lowdown
Alright, Rusty here. Let’s have a look at what’s on the table for the next couple of weeks.
Alright, mate, I’ll level with you – it’s looking pretty bleak for a proper paddle. For the entire 16-day window, there’s just nothing doing. We’ve got a long dry spell here. The Box (beach and reef) is the only spot in the mix, and it’s a tricky one even on a good day – inconsistent, only for the advanced crew, and it’s showing zero surf worth getting excited about for the whole stretch. The combined swell energy never climbs above weak, barely hitting 47 at the very end, and for most of the run it’s flat as a tack.
Right now, from the 13th of September, it’s dead. We’ve got a long gap with no real surf on offer. The first week and a half is just small dribbles – maybe 0.3ft to 1ft of short-period slop, mostly from the NE or SE, and the wind is never your friend. It’s either cross, cross-on, or straight onshore. For a break that needs a clean ENE swell, we’re not getting it. The water temp is sitting at 79°F with a 3°F anomaly, so it’s a touch warmer than usual for this time of year – feels nice for a swim, but not for a wave.
Come the 20th of September, there’s a fleeting moment of glass on the Sunday morning, but it’s a pathetic 0.3ft of swell. Not worth wetting a suit for. Even the last few days, around the 27th and 28th, we see the combined energy creep up to 47, but the swell is still only 2ft and the wind is howling cross-on or onshore at 12-15 mph. That setup is more interesting for a kite surfer than a paddle surfer – strong wind, messy chop, and tiny waves. The Box is a beach-and-reef spot, so with that combo, forget it.
Bottom line: there’s no standout session here. Not a single window where I’d point you to paddle out. A blank run like this isn’t unheard of for the area – sometimes the ocean just shuts down for a bit. Forecasts can change, but right now, keep the board in the car and wait for the next pulse.

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.
