The Lowdown
Alright, let’s be real with you. Looking at the whole picture, it’s pretty bleak for a while. We’ve got a long stretch of flat, weak, and messy stuff before anything even looks like a wave. Nothing worth paddling out for until Tuesday the 11th, and even that is barely worth mentioning. We’re looking at a solid week of nothing – a real flat spell – before things start to stir again around the middle of next week.
Right now, and for the next bunch of days, it’s all small, short-period windswell with bad shape. The energy is just absent, mostly in the weak 30 to 50 range, with a brief, still weak, bump to just over 100 mid-week. Mornings might look glassy, like Tuesday morning with that light NW air, but there’s nothing underneath to ride.
We finally get a pulse that breaks the total flatness on Tuesday the 11th. The morning brings a glassy start with a small 2ft swell from the NW, period around 8 seconds, and a combined energy reading of 109 – still weak, but it’s something. It’s a wave, but it’s not Mundaka. That short period is no good for this spot.
The real change comes around the weekend of the 15th and 16th. Saturday the 15th morning sees a jump in size – about 4ft from the NW with an 8-second period, and the energy reading jumps to 264, the strongest of the whole window. The wind is light and glassy, so it’ll be clean at first. That’s your standout, but I’d call it promising rather than a lock. It’s still a week out, so don’t build it up too much, but it’s the first sign of life.
Sunday the 16th keeps that similar pulse – a touch bigger at 4ft, but with energy dropping to 165 – and the morning again looks glassy with light wind. It’s similar to Saturday, maybe a bit more size but less push behind it. A second chance at a wave, but nothing special. The period is still short, so Mundaka won’t be doing its best work, but it will be surfable.
This is a river wave, so it really needs that long-period groundswell to get good. These 7-8 second pulses are more like windswell bumps. The best of the bunch is Saturday the 15th, and even that is more about clean conditions and a bit of size than any real quality.
Water temp is about normal for this time of year, nothing odd there.
So, that’s the story. Wait out the first week, keep a loose eye on the weekend of the 15th and 16th. It’s not firing, but it’s better than nothing. Keep the expectations low and the board waxed.

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.
