The Lowdown
Alright folks, it’s Rusty here. Let’s have a look at what’s on the cards for the Basque Country over the next couple of weeks. We’ve got one spot on the radar, and it’s a classic: Mundaka. The setup looks promising, but it’s a bit of a mixed bag with some absolute gems and some total duds in the mix.
We kick off right away, no waiting around. The first call is for the morning of Saturday, the 29th of August. The water is sitting at 75°, which is much warmer than normal for this time of year, a solid 5° above the average. A nice little bonus for your session.
Saturday morning is the main event to start. We’re seeing a clean 5ft swell from the northwest, with a solid 9-second period. The wind is a light offshore from the SSE at 3 mph, so it’s going to be clean. The combined energy is moderate at 397. This is a proper standout for the early part of the outlook. You’ll want to be on it, but remember, this is a crowd favourite, and it’s often busy, so expect company.
The afternoon on Saturday goes south fast. The wind swings onshore from the north, and the quality drops off completely. Forget about it.
Sunday the 30th is a different story. The morning is looking glassy with a 5ft northwest swell, a 10-second period, and absolutely zero wind from the WNW. That’s a glass-off situation. The water is clean, and the energy is still moderate at 373. This is another top-tier window. The afternoon, however, gets messy with a cross-onshore wind, so make the morning session count.
Monday the 31st gives us another morning to chase. The swell holds at 5ft from the northwest, 9-second period, and the wind is light offshore from the west at 3 mph, making it glassy. The energy is up to 449. This is a solid, clean morning. The afternoon is a write-off with onshore winds.
Tuesday the 1st of September and Wednesday the 2nd are poor. The swell drops, and the wind is either onshore or cross-shore. We’ve got a couple of glassy mornings, but the swell is tiny, with energy dropping into the double digits. It’s surfable but very ordinary, not worth a trip.
Thursday the 3rd and Friday the 4th are forgettable. The swell is tiny, and the wind is onshore. A real flat spell.
Now, here’s the long-range promise. Saturday the 5th of September. The morning brings a clean 3ft swell from the NNW, but check out the period: 14 seconds. That’s a long-period groundswell. The wind is glassy from the ENE at 3 mph. The combined energy is a strong 474. This is a standout, but it’s a week out, so keep an eye on it. The long period means it will be great for Mundaka’s point setup, but it might be a bit too straight for a beach break. The afternoon gets chopped.
Sunday the 6th of September has another promising morning: 4ft from the northwest, 11-second period, glassy wind from the east at 3 mph, and moderate energy at 346. Another clean window.
After that, from Monday the 7th through to the end of the forecast on the 13th, the conditions look poor. The wind turns onshore or cross-shore, and the swell stays small and weak. There are a few mornings with light winds, but the swell is just too small to get excited about, with energy figures dropping below 100. It’s a long, flat spell to finish the outlook.
So, to sum it up: the absolute best windows are the mornings of Saturday the 29th, Sunday the 30th, and Monday the 31st of August. The long-range tip is the morning of Saturday the 5th of September. Get on it while it’s good, because the flat spells are long.
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.
