The Lowdown
Right, folks, Rusty here. Let’s have a look at what’s cookin’ for the next couple of weeks.
The story for Mundaka is a real slow burn. We’ve got a solid, consistent break that thrives on a northwest groundswell, but the start of the window is a struggle. The first real glimmer of hope comes on Sunday morning, the 6th of September. That’s when we’ve got a clean 4ft set from the NNW with a 12-second period, and the wind is a total zero – glassy as. The energy is strong (464), and that’s the standout for the entire first week. It’s a river mouth, so you’re looking for that long, rifling left. The crowd is ‘often’ a factor here, so get there early if you’re an expert. This is the best on offer.
The pattern for the rest of the week is frustrating. The wind shifts onshore or cross-shore for almost every afternoon session, killing the quality. The mornings are the only real chance, but the swell is tiny and weak, like 1ft to 3ft, with energy down in the double digits. There’s a couple of glassy mornings, like Wednesday the 2nd with 3ft and Saturday the 5th with 3ft, but they’re just ordinary. You’ll be sitting on a longboard just bobbing around.
Then we hit the second week, and it’s a waiting game. The mornings are generally better, but the swell is still pretty average. The real promise is for Wednesday morning, the 16th of September. We’ve got another glassy session, wind from the WSW, with a 3ft, 12-second NW swell. The energy is strong (337) and the conditions look good. It’s a long-range call, so it’s a hopeful one, but the signs are there for a very clean, proper Mundaka day. The afternoon chop will likely spoil it again, but that morning session is your target.
Overall, this sixteen-day window is a proper test of patience. The first week is a dry spell with very few rideable moments. The second week has a couple of promising windows, but it’s a pick-and-choose game. The water is a touch warmer than normal for this time of year, so the rubber suit can be a bit thinner.

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.
