The Lowdown
Alright, Rusty here. Let's have a look at what's cookin' for Mundaka over the next couple of weeks.
Right off the bat, I gotta be straight with ya – it's a rough start. The forecast is looking pretty bleak for the next week or so. We've got a lot of onshore and cross-offshore winds messing things up, and the swell just isn't cooperating. The first few days are a write-off, with strong south-westerly winds up to 19 mph on Saturday the 25th, making for lumpy, poor surf. It's the same story through Sunday and into Monday, with only marginal conditions at best. There's a bit of a tease on Tuesday the 28th morning – the wind goes light cross-off from the east, and the surf cleans up nicely with a 4 ft NW swell at 10 seconds, but it's a very small window before the wind goes bad again. The combined energy is moderate, sitting at 333.
After that, we're in for a real dry spell. From Wednesday the 29th right through to Sunday the 10th of August, it's mostly small, weak, and choppy. You'll see a lot of glassy mornings, particularly on the 30th, 31st, and 1st of August, but with swell barely scraping 2 ft, you're not gonna be getting wet for much. The water temp is at 76°F – about 7°F warmer than usual, so it's very warm for the time of year.
Now, there is one glimmer of hope way out there. On Monday the 4th of August, the models are hinting at a solid pulse of NW groundswell. The Monday morning session is showing a 5 ft swell from the NW with an 11-second period. That's a proper groundswell, and the combined energy is a very strong 720! The wind is a light cross-shore from the east, which could make for clean conditions. This one is for the experts only – Mundaka at that size and with that energy is a serious wave. The afternoon looks a little more onshore and choppier though.
The Tuesday after that, we've got a light cross-offshore wind on the 5th of August, but the swell is back down to 3 ft, so the magic won't last. The rest of the second week looks small and wind-affected again.
So, to sum it up: if you can wait, the standout is unquestionably the Monday morning of the 4th of August. That's your best bet for a proper session at the famous river mouth. It's a long way off, so keep an eye on it. For now, you might be better off finding a spot with a bit more shelter, or just wait it out. The rest of the run is pretty average, but that's the Basque country for ya.
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.
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.
