The Lowdown
Alright folks, Rusty here. Let’s look at what’s cookin’ for The Box over the next couple of weeks.
Straight up, it’s a tough stretch. The Box is an advanced, inconsistent spot and this forecast is a long, flat spell with barely a ripple. The water is a touch warmer than normal for this time of year, sitting at 79°.
We’re staring at over a week of nearly nothing. From Friday, September 4th right through to Tuesday, September 8th, it’s pretty much flat with combined energies mostly at 1 or even zero. The few tiny pulses we see are under 0.3 feet – not worth waxing a board for.
The first real blip of surfable energy shows up on Wednesday, September 9th, but it’s a mess. A strong cross-onshore wind from the NNE at 25 mph kicks up a 3 foot swell from the NE with a short period of 5 seconds. The combined energy is weak at 30, and conditions are described as messy. By the afternoon, the swell bumps to 5 feet from the NE, period at 6 seconds, and energy hits 156 (moderate). But with that fresh NNE wind still blowing 22 mph cross-onshore, it’s lumpy and poor. This is a kite surfer’s setup, not a paddle surfer’s.
Thursday, September 10th is the best of a bad bunch, and it’s still nothing to write home about. The morning brings a clean little 3 foot swell from the NE (period 7 seconds) with a light cross-offshore breeze from the NW. Combined energy is a weak 75. The report says “surfable waves but very ordinary conditions,” so you could get a few grovelly ones if you’re desperate.
After that, it’s back to the doldrums. From Friday, September 11th all the way through to Saturday, September 19th, we see tiny slivers of swell, mostly under 1 feet, with periods all over the shop and combined energies in the single digits. Winds are often clean or glassy, but there’s simply no ocean energy to work with. The Box is a beach and reef setup that needs a proper ENE swell, and we’re just not getting any love.
So, no standouts here. This is a blank run that’s pretty normal for an inconsistent spot like this. Keep the board in the car, and check back later – forecasts can change.
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.
