The Lowdown
Alright, Rusty here. Let's break down the long-range look for The Box.
Truth is, it’s a grim outlook. The Box is an advanced, inconsistent break, and for the next 16 days the forecast is basically dead. There’s a long stretch of poor surf that runs from now right through the end of the month. Water temperature is 84°F, which is much warmer than usual for this time of year – feels like a warm bath.
We’re stuck with tiny, short-period windswell for most of the period, with wave energies staying weak (under 100). The first real bump comes on Friday, September 4th, when a moderate pulse of energy hits – combined energy reading 172 – but it’s a 5ft, 6-second windswell from the NE. It’ll be messy, and with light onshore wind, it’s just sloppy. Not worth your time.
The only half-decent moment is Saturday morning, September 5th. The Box gets a 3ft, 7-second swell from the NE, with a light offshore wind from the WSW. That’ll be clean. But the energy is still weak (75), and the period is short, so it’s small, crumbly, and gutless. It’s the best we’ve got, but that’s not saying much.
After that, it’s flat again. If you’re looking to paddle, this is a dead zone. The setup looks more interesting for kite surfers than anyone else.
Rusty.

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.
