The Lowdown
Alright folks, Rusty here. Let’s have a look at what’s cooking for the next couple of weeks.
To be straight with you, it’s a bleak run. We’re looking at a solid 16-day stretch with nothing but poor surf conditions on the cards. The Box is an inconsistent, advanced-level beach and reef setup, and for this whole period, the swell just isn’t showing up in any meaningful way. From Saturday the 18th of July right through to Sunday the 2nd of August, every single session is labeled as poor. There’s no standout, no hidden gem, no sneaky window—it’s all flat or close to it.
The first few days are a write-off. Saturday the 18th has a tiny 0.7ft to 1ft swell from the NNE and NE, with periods around 3 to 5 seconds. Combined wave energy is barely a whisper (1 to 4). Winds are cross or cross-on, and the water is a balmy 81°, which is much warmer than usual for this time of year—a real anomaly, over 2 degrees above normal. That’s about the only notable thing.
Sunday the 19th is even worse—1ft max, with a 2-second period at one point. That’s not surf, that’s a lake ripple. Monday the 20th and Tuesday the 21st have zero swell energy showing at all. It’s flat.
We do see a tiny blip of energy on Wednesday the 22nd of July morning, with a combined energy of 7, but it’s still only 1ft from the NNE, period 4 seconds. By Thursday the 23rd morning, the wind goes offshore from the SW, which is promising, but the swell is still only 1ft with a 6-second period. You’d be struggling to get a ride.
The best the whole period gets is Saturday the 25th of July morning. The wind goes glassy, flat calm, from the W, and the swell hits 1ft from the NE with a 7-second period. Combined energy is 17. That’s still tiny, but if you’re desperate and on a longboard, you might find a knee-high wall. The Box is fairly exposed to the ENE swell, so that NE direction is workable, but with no size, it’s barely worth the paddle.
After that, it’s back to near-zero. The end of the month sees a slight uptick on Wednesday the 29th of July, with 2ft from the E, period 6 seconds, and combined energy hitting 31 and 35. But the wind is onshore from the ENE, and there’s risk of thunderstorms. Not exactly inviting.
The long-range stuff into the first few days of August is the same story—flat, weak, or onshore. Sunday the 2nd of August morning goes glassy again from the SSW, but with only 1ft of swell, it’s still a flat day.
Bottom line: there’s no surf worth chasing in this 16-day window. The whole stretch is a gap of poor options. The Box is an inconsistent spot to begin with, and this run of flatness is pretty normal for the area when there’s no swell pushing in. Forecasts can change, but right now, keep the board in the car and don’t hold your breath.
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.
