The Lowdown
Alright, grab your board, let's talk about what's happening in the Basque Country over the next couple of weeks.
It's gonna be a tough stretch to start. For a world-class wave like Mundaka, the swell windows are just not lining up with clean conditions. We're looking at a solid week of small, weak surf or choppy, blown-out junk. The water is sitting at a very warm 76°F, which is much warmer than usual for this time of year, so at least you won't need a thick wetsuit, but don't get your hopes up for anything rideable.
From Saturday the 22nd through to the 4th of September, it's a real write-off. The energy in the water is almost non-existent, with combined swell energy readings barely cracking 100 and often sitting in the low double digits. You'll see a few pulses of swell from the NW, like a 4ft on the 22nd at 9 seconds, but easterly winds will have it chopped up. There's a brief moment on Wednesday the 26th with glassy conditions and a tiny bit of period, but the swell is only 1ft and the energy is a mere 58; not enough to push a decent wave down the point.
The only real glimmer of hope is for the experts, and it's a long way off. On Friday the 28th of August, the morning session is the standout. A solid 10ft NW swell with a long 11-second period rolls in, packing a massive 2425 combined energy. This is serious, powerful groundswell. The wind is a clean offshore from the SW, which will keep the wave face smooth. Be warned, at over 8ft, this is strictly for the experts only. The afternoon we get a strong onshore that will ruin it, so it's a very brief window. That Friday morning is the only real shot at glory in the entire forecast, but it's a real big one.
After that, the surf dips back to small and weak for a few more days, with nothing worth paddling for until we get to the following weekend. Saturday the 6th of September shows some promise with a morning offshore breeze and a building 4ft swell on a long 11-second period, hitting a moderate 407 energy. It's the best of the second week by a long shot, but it's still a two-week wait. For now, keep the board in the car and wait for that solid NW swell on the 28th.

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.
