The Lowdown
Alright, folks, Rusty here. Let's have a look at what the next couple of weeks are serving up at Mutriku. It's a bit of a slow burner to start, but there are some definite windows of clean potential if you're patient.
The opening days are pretty flat and uninviting, honestly. Friday and Saturday mornings are clean and glassy, but the swell is weak – we're talking 2ft to 2ft of mostly wind swell with combined energies in the weak range (89 and 46). Not worth suiting up for anything more than a splash. We've got a few days of this small stuff before things start to move.
The first real glimmer of hope shows up on the morning of Sunday the 13th. It's still on the smaller side at 4ft, but that's a proper NW groundswell with a long 13-second period, and the combined energy jumps up to 543 (moderate), which is a big step up. With the winds glassy out of the east, Mutriku should be clean and playful. This is a reef setup, so that long-period swell is right at home here. Keep in mind this spot is inconsistent, so you have to grab it when it's good. It's a beginner-friendly break, and this looks like a great session for those looking to get some clean waves. The water temp is about average for this time of year, so you won't need a thick suit, but a good springsuit will do.
Sunday afternoon goes a bit onshore, so make the most of the morning. Monday the 14th looks similar, with early glass and 4ft of groundswell, but it's a bit weaker and the score isn't as high. Still, it's surfable. The rest of that week, from Monday afternoon through to Thursday, gets messier. The wind swings cross-shore and cross-on, the swell gets a bit jumbled with shorter periods, and it's mostly poor to marginal. There's a push of energy on Thursday the 17th, with 5ft, but the wind and chop will likely spoil the party. Not the time to skip work for a session.
After that, things clean up again. Friday the 18th sees the swell dropping back to 3ft with glassy conditions – worth a look for a fun, smaller wave. Then we get to the real standout of this whole period. The morning of Saturday the 19th is looking special. The swell is up to 5ft from the NW with a strong 13-second period, and the energy is right up there at 871 (strong). The wind is dead calm – absolutely glassy. This is the pick of the bunch, folks. Clean, powerful, and on a reef. Get on it early. The afternoon looks like it turns a bit onshore, so the morning session is the one.
Sunday the 20th is another good one for the morning. Slightly bigger at 5ft, still a solid 12-second period from the NW, and light ENE winds leaving it glassy. The combined energy is 747, so it's packing a punch. This is a standout too. Mondays and Tuesdays after that have more clean mornings, with 5ft to 5ft surf, but the energy fades a little. Then we get to the second week, and it's a bit more of a mixed bag.
Mid-week, around the 23rd and 24th, the size is there – 5ft to 6ft – and energy is moderate to strong (up to 1050), but the winds are a little more crossy, so the surface won't be as pristine as the weekend before. There are still some rideable waves, but it's not as clean.
The last day on the cards, Saturday the 26th, sees the swell backing down to 4ft, with light cross-shore winds. It's still workable, but the magic of that 19th and 20th will have passed. So, mark your calendar for the mornings of the 19th and the 20th. That's where the real quality sits. The early call is more reliable, but those longer-range ones are looking promising too.
Remember, it's a reef at Mutriku, so those long-period swells will be lining up nicely. It's inconsistent though, so when the window opens, don't sleep on it.
Stay stoked.

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.
