The Lowdown
Alright, crew, Rusty here. I’m not gonna sugarcoat it: this next stretch for The Box is a total bust. We’ve got a 16-day window, and there ain’t a single decent wave in it. Nothing. It's a bummer to report, but that's the reality of it.
This is one of those long, flat spells that tests your patience. The spot is known to be inconsistent, but this is looking like a complete shutdown. The swell energy is just weak, with most days showing pitiful numbers in the single digits. For the first few days, there’s basically nothing at all.
We see a tiny blip of energy on Monday the 17th, but it’s attached to a 0.5m, 5-second windswell. That’s barely a ripple. The 19th is similar, with another weak pulse, but the swell is just too small and disorganized. It's not going to break with any kind of power. The ocean is going to be flat and mostly messy.
The one thing that is notable is that the water is very warm. On that first Saturday, it’s sitting at 84°F, which is a massive 6°F above the norm for this time of year. That’s really unusual. It makes for a nice warm swim, but with no waves, that’s all it’s good for.
We do see a bit more energy trying to show up around the 24th and 30th, but the wind is going to be onshore, which will ruin whatever small waves might try to form. This isn't a surf forecast, brothers. It’s a forecast for flat, choppy water. If you’ve got a kite, this might be your window, but for a surfboard? Leave it in the shed. Best to find another hobby for a couple of weeks. Things can change, but right now, it's a long, dry spell.
Rusty, out.

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.
