The Lowdown
Alright folks, Rusty here. Let’s take a good hard look at the surf forecast for The Box over the next 16 days. I gotta be straight with you – this outlook is a tough one. We’re looking at a long, blank stretch with barely a ripple on the cards for the most part.
Right from the start, the first week and a half is pretty grim. From Wednesday the 26th of August, through to the end of the month, and well into the first week of September, we’ve got next to nothing. The combined energy levels are pitiful, mostly reading in the single digits (1 to 30). The swell heights are tiny – we’re talking 0.3 ft to 2 ft at best – and with periods mostly under 6 seconds, it’s just wind chop with no shape. Winds are a mixed bag of cross, cross-off, and cross-on, so don’t expect any kind of clean, lined-up wave.
The water at The Box is sitting at 83°F when we start, which is 4°F warmer than average for this time of year – that’s notably warm, so you’ll be in boardshorts for sure, but the lack of surf will keep you out of the water.
There’s a tiny glimmer on Saturday the 29th of August, with a 2 ft to 2 ft swell showing up from the NNE/NE, but with a period of just 3-4 seconds and moderate cross-shore chop, it’s not worth paddling out for. By Sunday the 30th, we get the highest energy reading of this whole dreary period – a combined 30 from a 2 ft NE swell with a 6-second period – but that’s still just poor, crumbly surf. Honestly, if you’re a kite surfer, the moderate cross-shore winds and lack of real swell might make a beach setup more interesting than paddling.
After that, we hit a real dead zone. From Monday the 31st of August all the way through to Wednesday the 9th of September, there are days with literally zero energy (0) and no wave height. There are a couple of glassy mornings, like on Saturday the 5th of September and Sunday the 7th, but with only 0.3 ft to 1.0 ft of swell, it’s flat, smooth, and unrideable. The calm, glassy conditions are a tease – beautiful water, but nothing to surf.
The second week doesn’t offer any hope. A brief spike on Tuesday the 8th of September gives us a 2 ft to 2 ft ESE swell with a 6-second period and a combined energy of 20-29, but it’s plagued by cross-onshore winds in the afternoon. The following morning is glassy again but with no swell at all.
To put it plainly, there are no standout sessions in this 16-day window. The Box is an inconsistent spot that rarely breaks as it is, so this blank run is more normal for the area. Don’t bother dragging your board down. Check back with me in a week or so; forecasts can change, and it tends not to stay this hopeless forever.
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.
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.
