The Lowdown
Alright folks, Rusty here with a look at what Mundaka's got cooking for us over the next couple of weeks. It's a bit of a slow burner, so let's get into it.
Right off the bat, we’ve got a bit of a wait on our hands. The next few days are pretty grim, with poor conditions and marginal surf. The water is sitting at a balmy 73°F, which is a notable 4°F warmer than usual for this time of year—a real treat if you can get in.
Sunday the 6th starts with a risk of thunderstorms and a light cross breeze, with a 5ft NW swell (12-second period) pushing in. The combined energy is moderate at 614, but the onshore wind messes it up. It’s an expert-only wave here, and with the conditions as they are, it’s not worth the paddle out. That afternoon and Monday are even worse, with smaller, choppier waves.
We don't see anything worth getting excited about until Friday the 11th morning. We get a tiny 3ft NW swell (9-second period) with glassy conditions from an ESE breeze. The energy is weak (112), but for a quick splash on a longboard, it might be alright. Still, it’s very ordinary.
The real standout window looks to be Monday the 14th. Monday morning offers up a clean 4ft NW groundswell with a nice 12-second period. The wind is glassy from the NNE, and the combined energy is a solid 405. This is the one to circle. Mundaka is a river mouth that loves a long-period NW swell, and with light winds, it should be absolutely firing. Just remember, it’s an expert wave and it’s often crowded, so expect company.
The following week looks a bit of a mixed bag. We’ve got another promising window on Sunday the 20th morning with a clean 4ft NW swell (11-second period) and cross-off winds. That’s a good sign. Then Monday the 21st morning looks even better with glassy conditions and a 4ft NW groundswell (11-second period) and 424 combined energy. That could be a real sneaky good one.
For the rest of the time, expect a lot of onshore wind and choppy conditions, especially mid-week when the wind cranks up to 19 mph from the NW on Wednesday the 16th. That’s more of a kitesurfing session than a paddle session.
So to sum it up: the first week is a write-off. Hang tight for Monday the 14th morning and then keep an eye on Sunday the 20th and Monday the 21st for the cleanest conditions. Long-range stuff is always a bit less certain, but the signals are there.
Stay patient, stay stoked.

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.
Mundaka is 2 km (1 miles) from Bermeo. If you plan a holiday in Pais Vasco, look for hotels and other accommodation in Bermeo. Bermeo has rooms for a wide range of budgets as well as car hire and transport links.
