The Lowdown
Alright, grab your coffee. I’m Rusty, and I’ve been staring at the charts for The Box. Let’s be honest right off the bat: this forecast is a tough one. The Box is an advanced, inconsistent spot that rarely fires, and over the next 16 days, it’s mostly a waiting game. There’s a long stretch of flat, weak, or messy conditions ahead, but there is a brief light at the end of the tunnel.
The water temperature is sitting at 82°, which is a solid 4° warmer than usual for this time of year. That’s a notable anomaly, so you’ll be surfing in a warm bath.
Looking at the run of days, from Thursday 27 August right through to Monday 7 September, the story is the same: tiny, poor surf. We’re talking swell heights of 0.0ft to 2ft, with periods barely reaching 7 seconds, and combined wave energy is stuck in the weak range, mostly under 100 (often just 0-3). There’s nothing to get excited about. The winds are light and variable, sometimes glassy or cross-off, but there’s no swell to work with. You’ll be sitting on a flat ocean.
Then, on Tuesday 8 September, something finally stirs. The morning brings a 5ft NE swell with a period of 6 seconds. The combined energy jumps to 184 (moderate), and the wind is light and cross-off, keeping the surface clean. But it’s still a short-period swell, so the waves will be a bit lumpy and fat. The forecast says “surfable waves but very ordinary conditions.” It’s the best on offer in the entire window, but it’s not a standout. The Box demands a proper swell, and this is just a pulse.
The afternoon of the 8th sees the swell hold at 5ft NE with a slightly longer 7-second period, and energy climbs to 273 (moderate). But the wind swings light cross-onshore, adding a little texture. Still surfable, but not clean.
After that, things drop back again. Wednesday 9 September through Friday 11 September shows small, weak swell (1ft to 3ft) with poor to poor conditions. The combined energy stays low, except for Friday afternoon when it hits 109 (still moderate) but with a messy cross-onshore breeze and a lumpy sea state.
So, the one and only window to paddle out is Tuesday 8 September. The Box is a wave that needs a clean, strong swell, and this is a weak, short-period event. If you’re an advanced surfer and you’re desperate, you might find a few closeouts. But honestly, this setup looks more interesting for kite surfing than paddle surfing. Keep an eye on the charts, but don’t hold your breath.

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.
The Box is 4 km (2 miles) from Javea. If you plan a holiday in Valencia, look for hotels and other accommodation in Javea. Javea has rooms for a wide range of budgets as well as car hire and transport links.
