The Lowdown
Alright, this is Rusty. Let's talk about what's on offer for the Basque Country.
Right off the bat, I gotta be straight with you – the next week and a half is looking pretty grim. We've got a long stretch of poor surf conditions ahead, with no real recommendations until the very end of the period. The first signs of life don't show up until Monday, July 27th, and even then it's a marginal call. So, we're looking at a solid gap of several days with nothing worth paddling out for.
The water at Mundaka is sitting at a balmy 76°, which is a whopping 7° warmer than usual for this time of year. That's very unusual, and you'll feel it.
Now, let's get into the details. For the first week here, from Tuesday, July 21st, right through to Sunday, July 26th, the forecast is a total write-off. The wind is mostly onshore or cross-onshore, and the swell is weak and short-period. On Saturday, July 25th, a strong breeze from the west kicks up a messy 6ft to 8ft swell, but it's all wind-slop and lumpy. The combined energy is moderate to strong (266 to 625), but it's just not surfable. That kind of setup on a beach-and-reef spot like this might be more interesting for the kite surfers than for us paddle guys.
The first real glimmer of hope is on Monday, July 27th. The morning session shows a 5ft NW swell with a period of 10 seconds, and a light cross-onshore breeze. The combined energy is a solid 348. It's a groundswell, which is a good sign, but the conditions are still only described as 'marginal'. The afternoon doesn't look any better.
We then have another dry spell until Wednesday, July 29th. That morning is the one standout in this entire 16-day window. The wind goes glassy, with a light breeze from the northeast. The swell is a small 3ft from the NW, but with a 9-second period, it's a clean groundswell. The combined energy is low (117), but the glassy conditions will make it super clean. This is for the experienced crew only, as the river mouth there can be a tricky beast. It's a consistent spot, but it often gets crowded, so you'll have company.
After that, the forecast trails off into small, weak, and choppy surf right through to Wednesday, August 5th. Nothing else really stands out as worth a special trip. The only time you might get a wave is the glassy morning on Tuesday, August 4th, but that's a tiny 3ft swell from the NNW with a short 7-second period and very low energy (64). It's a desperate call.
So, to sum it up: the best bet in this whole period is the glassy morning of Wednesday, July 29th, at Mundaka. It's small, clean, and offers a long-period groundswell for the experts. Don't get your hopes up for the rest of it.
Rusty.

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