The Lowdown
Alright, Rusty here. Let’s have a look at what’s cookin’ at Mundaka.
To be straight with you, the next couple of weeks look pretty grim for a proper session at this famous river-mouth wave. Don’t get your hopes up too early. The water is sitting at a toasty 75°, which is much warmer than usual for this time of year—almost 4° above the norm. That’s notable.
Right now, Monday the 10th, it’s tiny with a 2ft NW swell and an onshore breeze making a mess of things—not worth paddling out. Tuesday the 11th starts glassy in the morning with a 2ft NW swell, but the wave energy is weak (62) and the conditions are labeled "poor." That glassy window is a tease, but there’s just no power. Wednesday and Thursday stay small and crummy with cross-shore winds and barely any push. Friday the 14th through the weekend sees a slight nudge in energy, but the wind is never clean and the swell stays under 3ft, so still a no-go for a wave this particular.
Monday the 17th morning shows a glimmer: glassy conditions with a 3ft NW swell and moderate energy (107). It’s labeled "surfable but very ordinary," so you could get a few grovelly ones if you’re desperate, but this isn’t *the* Mundaka we know.
The real standout doesn’t appear until Tuesday, August 25th. That morning you get a clean, glassy start with a 5ft NW swell that has good punch, with combined energy of 502—that's moderate to strong juice. The period is 10 seconds, a solid groundswell, and it’s coming from the optimum direction for the break. This is the one window that looks genuinely good for experienced surfers. The afternoon gets a bit more size at 6ft but the wind swings cross-on and kills it. So if you can, aim for that Tuesday morning session. Crowds are likely at Mundaka, especially when it gets good, so be ready for company.
Overall, there’s a long stretch of poor conditions until that final Tuesday. For the rest of the run, the swell is either too small, wind-affected, or the energy is just too weak to make the wave work. Hold tight.

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.
