The Lowdown
G'day, it's Rusty.
I'll be straight with you – the next 16 days at Mundaka are a tough watch. We've got a long stretch of nothing but poor surf conditions, with the odd flicker of something surfable but nothing you'd get excited about. The first real chance of a wave that's not a total write-off doesn't arrive until Sunday the 23rd of August, and even then, it's only just surfable.
Let's walk through it. From Wednesday the 12th right through to the end of Saturday the 22nd, it's a grinding run of poor surf. The swell is tiny, mostly under 3ft, with a combined energy that's generally weak (values between 47 and 204). The winds are a real killer – constantly cross, cross-onshore, or just plain onshore, keeping everything choppy and messy. There's a lot of moderate breeze and even some stronger stuff, so the paddle out wouldn't be fun for no reward.
The first real break in the gloom comes on Sunday the 23rd of August. The morning shows a 3ft swell from the NNW with a 9-second period, giving a combined energy of 109 (moderate). The wind is a light ESE cross-off, which will clean things up. The guidance calls it "surfable waves but very ordinary conditions." It's not a standout, but it's the first window where you wouldn't be totally wasting your time. The water temperature is typical for this time of year.
Then we get another gap. Monday the 24th is a write-off with fresh to near gale force winds, and Tuesday the 25th is just as brutal with strong cross-shore winds. The swell is tiny, and the conditions are messy.
Wednesday the 26th of August offers a little hope. The morning sees a 3ft NW swell with an 8-second period, combined energy of 93 (weak), but the wind is a light SE cross-off, keeping it clean. The afternoon is even better with a glassy 3ft NW swell and a combined energy of 134 (moderate). Again, it's only "surfable waves but very ordinary conditions," but the glassy wind is a major positive.
Finally, Thursday the 27th of August shows some promise. The morning has a 3ft swell from the NW, but this one has a longer 11-second period, giving it a combined energy of 218 (moderate). The wind is a light WSW cross-off, keeping it clean. This is the best-looking window in the whole forecast. The longer period means better shaped waves, though at a beach break like Mundaka, it can sometimes make them a bit straight. Still, it's the pick of a poor bunch.
So, the honest truth is: don't hold your breath for the first ten days. If you're desperate, Sunday the 23rd is a maybe, but Wednesday the 26th and Thursday the 27th are the only real chances for a half-decent session. Conditions can change, but right now, it's a waiting game.
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.
