The Lowdown
Alright folks, Rusty here. Let’s look at what’s on offer for The Box.
Honestly, it’s a pretty grim stretch ahead. The Box is an advanced, inconsistent break that rarely fires, and this forecast does nothing to change that. We’re looking at a long, flat run with nothing worth paddling out for. The first few days are a write-off: Wednesday morning (9 September) brings a tiny 2ft north windswell with a shocking 4-second period and a stiff 35 km/h cross-onshore. That’s just messy. The 6ft that shows up Wednesday afternoon is wind-affected and lumpy – not the kind of size that makes up for the chop.
Thursday the 10th sees a bit more shape with a 4ft NE swell at 8 seconds, but winds are still cross-onshore. The combined energy is moderate (213), but the quality just isn’t there. From Friday the 11th right through to late September, it’s mostly flat or tiny – swells under 2ft, periods of 4 to 7 seconds, and a lot of glassy or clean conditions with no power behind them. The energy readings are in the single digits or low double digits, barely a ripple.
We do get a bit of a pulse on Wednesday the 23rd of September – a 3ft ENE swell at 6 seconds, combined energy of 75, but it’s cross-shore with a risk of thunderstorms. The afternoon cleans up with a light cross-offshore, but it’s still only 2ft. Not enough to get excited about.
There’s no standout here. The best of a bad bunch might be the clean conditions on Friday 11 September morning with a light cross-offshore, but that 2ft 6-second swell is barely enough for a log. If you’re a beginner, don’t even think about paddling out – the 6ft on Wednesday 9 September is too big for you, but it’s also too ugly to enjoy. The Box on this setup looks more like a kite-surfing zone when the wind picks up, especially during the stronger cross-onshore days.
The water temperature is about average for this time of year, so no surprises there. But honestly, this is a blank run. Save your energy and wait for a proper groundswell.
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.
