The Lowdown
Alright, let’s get into it.
The next couple of days are looking pretty flat and miserable around here. We've got a bit of swell on the way Thursday morning, but the wind is going to be messy, so it's not worth getting too excited about. We’re looking at a few days of small, poor conditions before things finally start to turn around.
That first real chance of something clean comes up on the morning of Sunday the 13th. Mutriku is an inconsistent reef break, so you have to pick your moments, but that morning is looking glassy with a 4ft NW groundswell. The energy is moderate at 603, and the period is a solid 13 seconds. That's a proper lined-up swell for the reef. The water's sitting at 74°F, which is 5°F warmer than usual for this time of year—that's pretty notable and means you can get away with a thinner suit.
The window stays open through Monday the 14th morning. Still glassy, still 4ft of NW, but the period drops a touch to 11 seconds and the energy settles to 406. Still worth a paddle if you missed Sunday.
Then it fades out again. Midweek is a write-off with small, choppy junk. We’re back to waiting.
The next proper highlight lands on Saturday the 19th. The morning session looks glassy again, 4ft of NW swell with an 11-second period and moderate energy at 426. It won't be as clean or powerful as Sunday, but it’s a solid, surfable morning.
But the real standout in this whole stretch is Monday the 21st. That morning, the swell jumps to a solid 10ft from the NW, with a 10-second period. The energy readings are huge at 1837—that’s strong to very strong stuff. For a reef break like Mutriku, that’s going to be a serious, powerful wave. The wind is glassy, so it should be holding some shape. Now, at 10ft, this is definitely expert territory. This is not a day for beginners. It’s also over 9 days away, so while it looks very promising, we treat that with some caution. The days after it ease off, with Tuesday the 22nd still seeing a solid 6ft in the morning under glassy conditions, and the rest of the week offering smaller but still clean windows.
So, if you’re picking your days, Sunday the 13th is the smart, clean call. Monday the 21st is the big one—if you’ve got the skills and the nerve, that’s the standout.

Information about the Mutriku Surf forecast
The above surf forecast table for Mutriku provides essential information for determining whether the surfing conditions will be good over the next 16 days. A general guide to surfing at Mutriku can be found by selecting the local surf guide option on the grey menu. Our Mutriku 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 (Mutriku) 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 Mutriku 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.
Mutriku is 16 km (10 miles) from Eibar. If you plan a holiday in Pais Vasco, look for hotels and other accommodation in Eibar. Eibar has rooms for a wide range of budgets as well as car hire and transport links.
