The Lowdown
Alright, Rusty here. Let's have a look at what's cookin' for our local jewel, Mundaka.
We're looking at a slow start, I'm not gonna lie. There's a very long wait ahead of us. The first few days are a complete write-off, with tiny, weak swell and the wind all over the shop. You'll see a bit of a pulse pushing through later in the first week, but the wind just won't play ball, keeping it messy and cross-shore. It's a proper frustrating stretch.
Things finally start to show a glimmer of life on the morning of Saturday the 29th. We get a bit of a bump, around 4ft, from the NW. The real story that morning is the glassy conditions. The water is much warmer than usual for this time of year, coming in at 76°F.
Sunday the 30th looks similar. Another morning of clean, glassy conditions with 4ft NW swell. These are your "get in the water because it's clean" sessions, not epic Mundaka. The energy is moderate (238). The weekday mornings of the 1st and 2nd of September offer more of the same, with light winds and clean conditions, but the swell is still just ordinary.
Now, the real standout is shaping up for Monday the 7th of September. This is the one you circle on the calendar. We’re looking at a solid 7ft NW groundswell, with a very long period of 13 seconds. The energy is very strong (1352). That combination of size and period is a proper freight train. The morning has a light cross-offshore wind from the WSW, which is the dream for keeping that famous left wall clean and lined up. This is for experienced surfers only – 7ft waves at Mundaka with that kind of power is not a beginner's game. The crowd is likely to be thick, as it always is when it starts pumping.
The days leading up to it are worth a mention too. The morning of Thursday the 3rd, with 4ft and 10-second period from the NW and glassy conditions, looks like a good, clean warm-up. The morning of the 4th is similar, with 4ft NW swell and glassy conditions. The morning of the 8th is also clean with 4ft NW swell, but the energy is definitely lower.
The best of the best is that Monday the 7th morning session. It's the one with the biggest, longest-period swell and the cleanest wind. After that, the 9th of September morning is another clean one with a very long period swell, but the size is smaller.
So, to put it simply: you've got a long wait for the good stuff. The first week is a bust. The second weekend has some clean, small waves. But the real deal, the one worth waiting for, is Monday the 7th of September. Mark it down.
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.
