The Lowdown
Alright folks, Rusty here. Let's have a proper look at what the Basque coast has in store for us, specifically at Mutriku. It's a real mixed bag, so don't get too excited just yet.
We've got a bit of a frustrating start. The opening days are a write-off, with poor conditions and no real surf on offer. The water’s sitting at a notable 74°, which is much warmer than usual for this time of year, but you won't be enjoying it much with the current state of things.
Wednesday the 9th sees a chunky 6ft NW swell arriving, packing a hefty punch of energy (486), but it’s completely let down by a cross-onshore wind that’s making a mess of things. It’s just not worth it. The swell drops through Thursday the 10th, but there’s a brief glimmer on Thursday morning. We get a clean 4ft NW groundswell and glassy conditions. The wave energy is still moderate (348), and the period is a solid 10 seconds, so the shapes should have some push. It’s surfable, but nothing to write home about.
Friday through Saturday are tiny and weak, with energy barely registering. Forget it.
Now, hold onto your board, because Sunday the 13th is the real standout here. We’re looking at a cracking 4ft NW groundswell with a very long 13-second period. The energy jumps right up (600), and with glassy conditions in the morning, this reef break will be absolutely pristine. This is groundswell at its best, and for a reef setup like Mutriku, a long period from the NW is basically the magic formula. The waves will have heaps of shape and power, with nice lulls between sets. It's the best on offer, by a long shot. The wind looks to shift offshore on Sunday afternoon, but the NE breeze will make it a little bumpy; the morning is the clear winner.
The following Monday, the 14th, is also a very solid option. Another 4ft NW groundswell, though the period drops slightly to 12 seconds. The energy is still very strong (427), and with glassy conditions again in the morning, you'll find clean, fun waves. The swell is about 4ft, which is perfectly manageable for intermediate surfers.
After that, the surf tapers off. We see a bit of push on Thursday the 17th with a 4ft WNW swell, but it's short-period (7 seconds) and the conditions are only so-so. It gets messy again after that. The second week looks pretty lean, with small, weak swells and mostly cross/onshore winds. There's a brief window on the 24th with clean offshore winds, but the swell is tiny at 2ft, so you'd be on a longboard or looking elsewhere.
Bottom line: Get out there on Sunday morning the 13th for the best waves of the forecast. Monday the 14th is your solid backup. The rest of the time, you're better off waiting for the next pulse.
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.
