The Lowdown
Right, folks, Rusty here. Let’s have a look at what’s on the cards for the Mundaka region over the next couple of weeks.
Honestly, I’ll get the bad news out of the way first. Looking at the whole 16-day window, it’s a grim picture. The conditions are just not cooperating. We’ve got a long stretch of poor surf ahead, with no real standouts to speak of. The first decent-looking surf doesn’t even appear until Wednesday, 29th July, and even then, it’s only just surfable.
Let’s run through it. From Monday, 20th July, right through to Tuesday, 28th July, the story is the same: weak, short-period swell and wind that’s either cross-on or onshore, making for choppy, messy conditions. The combined energy is low, mostly in the 28 to 170 range, which is weak. The water temperature is a notable 76°F on the Monday, which is 7°F warmer than usual for this time of year – very unusual. But you won’t be enjoying that warm water because the waves are a write-off.
There’s a bit of a pulse on the weekend of the 26th and 27th, with swell heights getting up to 6ft to 8ft, but the wind is strong cross-shore, and the energy jumps to 753 (moderate) on the Sunday afternoon. That’s not surfable for a paddle; that’s kite-surfing territory. The setup is a beach-and-reef mix, so with that strong cross-wind and lumpy chop, it’s just not for paddle surfing.
The only glimmer comes on the morning of Wednesday, 29th July. The wind goes glassy from the NW, and we get a 3ft swell from the NW with a period of 9 seconds (groundswell). The energy is still weak at 108. The report says "surfable waves but very ordinary conditions." It’s a 1 out of 10. For a wave like Mundaka, a river mouth, that long-period groundswell can be a bit tricky, prone to breaking straight, but with glassy conditions, it’s the only time you could even paddle out. The crowds will be a problem though, as it’s often packed here.
After that morning, it’s back to poor surf again for the rest of the week and into early August. The swell stays small, between 2ft and 4ft, and the wind is never right. There is simply no good surf on offer in this entire 16-day forecast.
That’s the long and short of it. It’s a frustrating run, but it’s how it goes sometimes. Hang in there.

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.
