The Lowdown
Alright, this is Rusty, and I’ve got a look at the Basque coast for the next couple of weeks. Honestly, it’s a pretty bleak run for the most part.
We’re looking at Mutriku, a sheltered reef setup that really needs a clean window to work, and for the first week and a half, it’s just not happening. The water is sitting at 76°F, which is about 5°F warmer than usual for this time of year – that’s a noticeable anomaly, kind of feels like a summer bath out there.
The real kicker is the lack of any decent swell. For the first eight days, we’re stuck with tiny, weak waves – the height barely gets above 3 ft, and the combined energy is mostly stuck in the double digits, like 51 or 87, just a dribble. The wind is either cross-on or light, but it’s enough to spoil the small stuff. Thursday morning the 13th and Monday morning the 17th have glassy conditions, but those 1 ft and 2 ft waves are barely ripples. It’s a frustrating start.
The first real pulse of any size shows up on Thursday the 20th, with a 6 ft NW swell, period around 12 seconds, and energy jumping to 866. That’s a proper groundswell, but it’s arriving with a cross-on wind, which will make it a mess. Not a day for the log, but it’s a sign of life. The following Friday morning, the 21st, has a 5 ft WNW swell, still with a cross-shore wind, so it’s wonky.
The one true standout, and I mean the only one worth circling on the calendar, is the afternoon of Tuesday the 25th. We’ve got a 8 ft WNW swell rolling in, with an energy reading of 1014 – that’s proper power. The period is a short 9 seconds, so the waves will be a bit steeper, but the wind is light cross-onshore, which is manageable. This is advanced territory; at 8 ft, it’s not for the groms. The reef at Mutriku will hold it, but expect a heavy lineup.
Outside of that, the morning of Wednesday the 26th has a 5 ft NW swell with glassy conditions, but the period is a short 7 seconds, so it’ll be a bit crumbly and weak. It’s a consolation prize.
The rest of the run is basically a write-off. Gaps of three or four days with absolutely nothing rideable. The energy stays low, and the wind stays onshore. If you’re a kite surfer, some of those afternoons with 9 mph cross-on winds and a bit of lump might look interesting, but for a paddle, it’s a grim stretch.
So, to sum it up: the best bet is the afternoon of the 25th for the big stuff, but be ready. Everything else is a scratch. The forecasts can change, but right now, this is a waiting game.
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.
