The Lowdown
Alright, Rusty here, and I’ll give it to you straight in feet and degrees.
This stretch is a tough one. The Box is a heavy wave when it’s on, but it’s inconsistent, and this 16-day window is mostly flat or tiny junk. Water temp is sitting around 81°F, which is a touch warmer than usual for the time of year, so at least it’ll be nice just floating.
Sunday the 30th of August, forget it. A tiny 1ft NE windswell with a short period of 5 seconds and weak energy (3). The morning has a cross-off wind, but that swell is useless. The afternoon gets worse with a cross breeze and moderate chop.
Monday the 31st and Tuesday the 1st of September are completely flat – zero swell. Glassy conditions, sure, but you can’t surf glass.
We see tiny bumps of less than 1ft to 1ft from the 2nd through the 6th of September. The period is short, mostly 2 to 7 seconds, and the combined energy never breaks past 7. Winds are all over the place – cross, cross-on, and glassy at times. The afternoon of the 3rd of September has a tiny 1ft ESE swell with an onshore wind – messy. None of this is rideable for a spot like The Box.
The best we get, and I’m stretching here, is on Monday the 7th of September. We see a little 2ft ESE swell with a 5-second period, energy at 29 (weak), and the morning is dead calm. Glassy. That’s about the cleanest it’ll be, but it’s still tiny and inconsistent.
On Wednesday the 9th of September, we see the biggest bump of the whole forecast – a 5ft NNE swell building to 5ft NE in the afternoon, with a 6-second period. The combined energy hits 122 (moderate) in the morning and 182 in the afternoon. That’s the closest we get to real surf. But the wind is cross-on in the morning and cross in the afternoon – not ideal. With The Box being a beach and reef setup, short period swell like this means it’ll be a bit crumbly and tough to get a clean barrel.
From the 10th of September onward, it’s back to tiny stuff. The 11th has glassy conditions but a 1ft NE swell – not worth paddling out for. By the 12th and 13th, we’re back to flat or very weak energy.
Honestly, there are no standouts here. If you’re desperate, the morning of the 9th of September has the most size, but it’s not great. The rest of the 16-day window is a blank run, and for an inconsistent spot like The Box, that’s pretty normal. Forecasts can change, but right now, I’d leave the board in the truck and enjoy the sunshine.

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.
