The Lowdown
Alright, this is Rusty. Let's get real about what’s coming up at Mundaka.
Honestly, for the next couple of weeks, it’s looking pretty grim for a paddle. I’m seeing a long stretch of tiny, weak surf and messy conditions that just aren't going to deliver the magic this place is known for. We’re talking a solid run of days from now until the 21st of August where the swell is just too small and the wind is all over the shop. The combined wave energy is weak, mostly sitting below the 100 mark (a couple of afternoons hit 105, but the quality is poor). There are a few glassy mornings, like Tuesday the 11th and Wednesday the 12th, and even next Tuesday the 18th and Wednesday the 19th, but the swell is barely 2ft from the NW. With a period of only 8 seconds or less on those days, it’s just not enough to get the river mouth working.
The one window that finally catches my eye is that Saturday morning, the 22nd of August. That’s the only standout in the whole run. We’re looking at a proper jump in energy – a 5ft NW swell with a combined energy reading of 266 and, crucially, glassy winds from the south. For a spot like Mundaka that needs perfection, a clean, offshore-style morning with that much more size is a real glimmer of hope. It’s still over a week away, so this is a long-range call, but if that window cleans up, it could be the only one worth paddling out for. Be aware that 5ft at Mundaka can be a proper expert wave.
For the rest of the outlook, honestly, with the persistent small, weak surf and often wonky wind, the setup looks way more interesting for a kite surfer than for someone on a surfboard. The water is running at a very unusual 75°F on that first Sunday, which is much warmer than normal for this time of year, but even that can’t save the surf.
Signing off,
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.
