The Lowdown
Alright folks, Rusty here. Let’s have a look at what’s shaking out for Mundaka over the next couple of weeks.
Well, to be honest, the first few days are a bit of a write-off. We’re looking at a slow start with no real surf on offer right through to Wednesday the 9th. The waves are small, with poor conditions and the wind is just not playing ball. You’re better off waiting.
The first real glimmer of hope comes on Thursday morning, the 10th of September. It’s not big, but for the first time, we’ve got some glassy conditions. The swell is sitting around 5 ft from the NW with a moderate combined energy (363), and it’s clean. It’s still relatively small, so it’s not a standout, but it’s a step in the right direction.
Now, what we’re really waiting for is Sunday the 13th of September. The morning session is the pick of the week so far. We’ve got a clean 4 ft NW groundswell with a period of 13 seconds, glassy offshore wind, and a solid combined energy of 554. This is a long-period groundswell, so it’s going to hold up well here at Mundaka’s river mouth. The wave shape will be proper, with good energy behind it. The water temp is about average for this time of year, so no surprises there. Expect crowds though, as this spot is often busy when it’s on.
The good news is Monday the 14th of September morning looks similar: glassy, 5 ft NW swell with a 12-second period and combined energy of 558. Another clean, quality window.
After that, the pattern gets a bit messy again through the middle of the week, but then Thursday the 17th of September morning brings it back. Glassy conditions with a 5 ft NW swell, 10-second period, and combined energy of 520. It’s a bit more size, but still clean. Not quite the same quality as the 13th, but a solid option.
Looking further out, Friday the 18th of September morning also has a glassy window with 5 ft NW swell, 416 combined energy. Not a massive standout, but a decent one to keep an eye on.
And then into the second week, Sunday the 20th of September morning is another glassy day with a 4 ft NW swell and 322 combined energy. It’s a smaller, cleaner option for those who want to avoid the bigger days.
Overall, the clear standout is the morning of Sunday the 13th of September. That’s the one to circle. The Monday the 14th and Thursday the 17th mornings are also very good, but the 13th has the best combo of clean conditions, a solid groundswell, and good energy. Don’t expect much before that.
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.
