The Lowdown

Alright, folks, Rusty here. Let me break it down for you. The next couple of weeks are a real mixed bag. We’ve got a lot of small, sloppy surf on the menu for most of the window, but there are a couple of windows where things could absolutely light up. You’re gonna need to be patient and pick your moments.

The first week is pretty much a write-off for any decent waves. From Tuesday the 11th right through to Tuesday the 18th, we’re looking at small swell, mostly under 3ft, with a lot of cross-onshore and cross-shore breeze messing things up. The water’s running at 75°, which is well above normal for this time of year, so you’ll be comfortable in a spring suit, but the surf just isn’t there. There’s a day or two with some glassy mornings, like Wednesday the 12th and Thursday the 13th, but with only 1-2ft on offer, it’s barely a ripple. You’d be better off finding a longboard and a sheltered nook, or just doing something else entirely.

We get a little bump of energy around Saturday the 15th and Sunday the 16th, with the swell picking up slightly, but it’s still short-period windswell, and the wind keeps it chopped up. It’s not worth getting excited about. Then from Monday the 17th into Tuesday the 18th, it drops right back off again. This is a proper flat spell, a real lull that’s going to test your patience.

Now, hold on, because things change. Around Wednesday the 19th, we start to see a more meaningful push of energy, with the swell building to around 5ft and the energy jumping up. But the wind is still cross-onshore, so it stays messy. Then on Thursday the 20th, the real deal starts to show up. The swell jumps to nearly 8ft, with a long-period groundswell from the NW at 12 seconds. The energy readings are strong. This is the start of the real stuff, even if Thursday afternoon itself is still looking a bit wind-affected.

But the standout, the one you’ve been waiting for, is Monday the 24th. Actually, the whole weekend is building toward it. By Monday morning, we’ve got a clean 7ft of NW swell, and the wind is glassy. This is what we live for. Mundaka (Basque Country) should be absolutely firing. This is a long, mechanical river wave, exactly what you want with this size and direction. It’s an expert wave at this size, no doubt, but if you can handle it, this is the session. The offshore wind is light and variable, promising clean, grinding walls.

And don’t sleep on Tuesday the 25th either. The morning looks just as good, with 7-8ft of NW swell and the glass again. It might be slightly bigger, but conditions look prime. This is another window where Mundaka could be world-class.

After that, we ease off again into Wednesday the 26th with smaller, more disorganized surf. So there you have it. A long, flat stretch to start, but a seriously promising finish. Keep your eyes on the 24th and 25th. Mark my words, if you can get out on that Monday morning, you won’t forget it.

Signing off, 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.
