The Lowdown
Alright, Rusty here. Let's have a look at what's coming our way.
Right off the bat, it is a lean start. The first few days are a write-off, with nothing but messy, weak windswell worth paddling out for. The sea is just out of sorts. We’ve got to wait until the morning of the 13th for anything to get our hopes up. That’s a solid dead spell to get through.
The standout window is the morning of Sunday, the 13th of September. The water is a much warmer than normal 74°, which is a solid 4° above the usual for this time of year, so it’s a real treat. The swell at Mutriku (reef) is a clean 5ft from the NW with a proper 13-second period, packing a solid punch with a combined energy of 878 (moderate wave energy). It’s glassy, dead calm wind, and the forecast says "expect good surf conditions." That’s the call. This is the best on offer: a clean, powerful groundswell hitting the optimum direction. Keep in mind Mutriku is a reef break and it's inconsistent, so don't expect a constant line-up, but when the sets come through, they'll be worth it. The morning is the time to be there.
The morning of Monday, the 14th, is another good option. It won't be as big as Sunday, at 4ft from the NW with a 12-second period, and the energy is down to 442 (moderate wave energy). But it's glassy again, and the quality is still "expect good surf conditions." It's a solid second choice, but Sunday morning is the one to circle.
After that, we drop back into a long stretch of poor surf, with onshore winds and choppy conditions. The morning of Saturday, the 19th, has a brief moment of "surfable waves but very ordinary conditions" with a 4ft NW swell, but it's nothing to get excited about.
Then, looking way out, the morning of Sunday, the 20th of September, pops up again. It shows 4ft from the NW with a 12-second period and a combined energy of 458 (moderate wave energy). It's glassy, and the forecast says "expect good surf conditions." It's a promising long-range call, but keep in mind it's a week and a half away, so we'll see how it firms up.
For the rest of the run, there's a lot of cross-shore wind and chop, so don't hold your breath for anything else.
Rusty.

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.
