The Lowdown
Alright folks, Rusty here. Let’s have a look at what’s cookin’ for the Mundaka region over the next couple of weeks.
Right off the bat, I gotta be honest with you – the next ten days or so are a real struggle. We’re looking at a long, dry spell with nothing but small, weak surf and poor conditions. The first week is basically a write-off. From the 8th right through to the 18th of August, the swell is tiny, mostly around 1.0 ft to 4 ft, and the period is all over the place – short, choppy stuff. The combined swell energy is weak, barely cracking 100 (mostly double-digit values like 18, 93, 106 – just not enough grunt). The winds are all over the shop too, mostly cross or cross-onshore, which is gonna leave it bumpy and messy. There’s a few glassy mornings, like the 11th and 12th, but with only 2 ft to 2 ft of swell and zero energy, you’re better off staying in bed. It’s a tough stretch.
The first real glimmer of hope doesn’t show up until the morning of Wednesday the 19th of August. The wind goes dead calm – glassy conditions – and the swell bumps up to 4 ft from the N. The energy climbs a bit to 148, but it’s still pretty weak. The water temp is a warm 76°F, which is a solid 5° warmer than normal for this time of year, so that’s a treat. Still, the waves are just “surfable but very ordinary” – not the Mundaka magic we’re after. The afternoon of the 19th starts to show a pulse, with a 6 ft swell from the NNW and energy jumping to 439, but the wind goes cross-onshore and ruins the party.
The standout – and I mean the only real window to pay attention to – is the morning of Thursday the 20th of August. We’ve got a 6 ft swell rolling in from the NNW, with moderate energy at 412. The wind is light and cross-shore from the E, which should keep things relatively clean. Now, this is a solid wave height – over 5 ft – so it’s not for the groms or beginners. And with the period sitting at 8 seconds, it’s a short-period wind swell, not a long groundswell. Mundaka is a river mouth, so it can handle a bit of everything, but don’t expect those long, lined-up walls. This is a punchy, short-period wave that will be fast and critical. The water is still warm, but the crowds here are “often” around, so expect a few heads in the lineup. This is your best bet in the whole 16-day window, but it’s a one-morning gig.
After that, the 21st and 22nd drop right back down to nothing, with weak, choppy onshore slop. The 23rd teases a bit of 2 ft NW swell with glassy morning winds, but the energy is pitiful at 101. Honestly, it’s a pretty bleak outlook for Mundaka. If you’re a kite surfer, the afternoons of the 15th and 16th with 4 ft and 3 ft in cross-onshore winds might be more your speed than a paddle surfer’s. For the rest of us, keep your eyes on that Thursday morning the 20th. It’s not perfect, but it’s the only shot.
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.
