The Lowdown
Alright, let’s talk about Zarautz. The water’s sitting at 77°, which is a solid 3° warmer than it should be this time of year. That’s a big deal – the sea’s feeling properly tropical out there for the Basque coast.
The short version is this: the next 16 days are a real mixed bag. The first week is mostly small, sleepy, and not worth paddling out for unless you’re desperate to get wet. Things start to wake up around the 21st, but it’s still not great. The real potential shows at the end, with a couple of promising windows that could be worth circling on the calendar.
Starting now, there’s nothing doing. Sunday the 16th has ankle-high dribble, 3ft, with weak energy (78). It’s glassy in the morning which is the only saving grace. This flat, mushy pattern holds through Tuesday the 19th. You’re looking at a few days of nothing but knee-high lumps. It’s a tough stretch.
We get a little pulse on Thursday the 20th. Morning sees 3ft from the NW with an 11-second period, and the energy jumps to a moderate 177. It’s glassy too. Still small, but the longer period means a bit more push. It’s not going to blow your mind, but it’s the first thing that looks like actual surf. The afternoon gets a touch more size (3ft) and energy (196), but the wind goes onshore and kills it.
Friday the 21st sees a bit more size – 5ft in the morning – and the energy hits 440, so there’s some muscle behind it. But the wind is cross-onshore from the NNE, so it’s going to be a bit lumpy and messy. It’s marginal at best.
The weekend of the 22nd and 23rd is pretty poor, with the swell fading back down to under 3ft. Not worth the paddle.
Here’s where things get interesting. Monday the 24th is the first day that could have some real power. The morning swell is already 6ft from the WNW with moderate-strong energy (476). But it’s still cross-onshore. The real story is the afternoon. The swell jumps to 12ft from the WNW, and the energy skyrockets to 1867 – that’s strong, powerful stuff. The wind is cross-shore and the comment says it’s predicted to be too big for Zarautz. If you’re an expert, this could be a beast, but honestly, that size on a beach break is going to be a washing machine. For everyone else, give it a miss. 12ft is way over the 8ft expert-only line.
Tuesday the 25th is the standout of the whole run. Morning sees 7ft from the NW with strong energy (753), but the key here is the wind. It’s a cross-offshore breeze from the SW, and the comment is “expect very good surf conditions.” It’s clean. This is your big one. At 7ft it’s still hefty, so not for beginners, but for anyone who knows what they’re doing, this is the pick of the fortnight. The afternoon disintegrates though – the wind swings WNW and cranks to 30 km/h, with the swell dropping to 6ft. It’s over quickly.
After that, it’s a slow fade. The rest of the week and into the next is all under 3ft, with weak to moderate energy. Thursday the 27th through Saturday the 29th is mostly tiny slop. Sunday the 30th and Monday the 31st see a small pulse to 3ft to 4ft from the NW, but the winds are messy and it’s not worth getting excited about.
So, the plan is simple. Let the small stuff pass. Wait for the 25th. Tuesday morning is your window – 7ft, clean cross-offshore wind, strong swell energy. That’s the one. The big swell on the 24th afternoon is for the brave and the foolish. Everything else is just exercise.

Information about the Zarautz Surf forecast
The above surf forecast table for Zarautz provides essential information for determining whether the surfing conditions will be good over the next 16 days. A general guide to surfing at Zarautz can be found by selecting the local surf guide option on the grey menu. Our Zarautz 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 (Zarautz) 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 Zarautz 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.
