The Lowdown

Alright folks, Rusty here. Let’s talk about the next couple of weeks for Mundaka. It’s a bit of a slow burn, but there’s a real monster brewing for the experts if you’ve got the patience.

We’re looking at a pretty quiet start. The first few days are a write-off, with tiny swells and poor conditions. The water is sitting at a very warm 75°, which is much warmer than usual for this time of year, so the wetsuit might be a bit thinner than normal.

Monday the 24th and Tuesday the 25th offer nothing. There’s a tiny 1ft to 0.3ft swell, but it’s basically flat. Wednesday the 26th and Thursday the 27th see a slight bump to 2ft and 3ft, with light winds and clean conditions, but the wave energy is weak (80 to 119). You might get a few crumbly closeouts, but it’s not worth the paddle.

Friday the 28th morning is our first real window. The swell jumps to 5ft from the NW, with a period of 8 seconds. The wind is light offshore from the WSW, making it clean. The combined energy is a solid 291. It’s not massive, but it’s a good sign that things are waking up. However, the afternoon gets ruined by a cross-onshore wind.

Saturday the 29th morning is the standout of the first week. We’ve got a glassy, clean 5ft NW swell with a period of 9 seconds and a serious 384 combined energy. That’s a proper wave running down the point. The wind is calm, so it’ll be perfect. Expect a lineup, as Mundaka is a consistent spot and crowds are often. This is the one to aim for.

After that, it drops off again through the end of August and into the first few days of September. The 31st of August afternoon has a big 6ft swell with a 10-second period and 614 energy, but the wind is onshore, making it a mess. There are a few mornings with glassy conditions and small 2ft to 2ft waves, but the energy is too low (64 to 81) to get excited about.

Now, hold onto your boards for the second week. The real deal arrives on Monday the 7th of September. This is a long-range standout, so don’t book the time off just yet, but it looks incredible. Monday morning brings a 7ft NW groundswell with a glassy surface and a period of 20 seconds. The combined energy is a massive 3690. That’s a deep, powerful, very long-period swell. At Mundaka, this is a dream scenario for experts. It’s a river mouth, so that long period will wrap in perfectly. The afternoon gets even better for the brave, with a 10ft NW swell, a 17-second period, and a monstrous 4998 combined energy. The wind is light offshore from the WSW. This is not for beginners. At over 8ft, it’s expert-only territory.

Tuesday the 8th will still have plenty of size, 6ft from the NW, but the wind is cross-shore and the conditions are a bit messy. Still, the energy is huge at 1069.

So, the bottom line: the first week is a slow grind, with Saturday the 29th morning being the best of a pretty average bunch. The second week, specifically the 7th of September, is the one to watch. If that forecast holds, it’s going to be a classic session.

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.
