The Lowdown

Right, grab a coffee, let's see what the Basque coast has brewin’ for us.

Mutriku is a reef-bottom set-up that’s usually pretty sheltered and can be a bit of a diva to get going. Over the next two weeks, we’ve got a real slow burner of an outlook. The first several days are a non-starter unless you're just happy floating around. The water feels like a bath right now, running much warmer than normal for the time of year – good news for your toes, but it doesn't help the waves.

We start with a long flat spell. From the 25th of August right through the morning of the 27th, you’re looking at tiny little bumps under 2ft, all with a period that’s too short to do anything. It’s a proper dud. That Thursday afternoon on the 27th, the swell bumps up to 3ft, but with a period of just 7 seconds, it’s gonna be weak and crumbly – the combined wave energy is low (91). Not worth the paddle.

We finally get a bit of life kicking in around the morning of Friday the 28th. Swell jumps to 6ft from the WNW with a moderate 8-second period, and we get a clean cross-offshore wind. The energy jumps up to a moderate level (365), and it’s surfable. The afternoon, however, gets messy with a cross-onshore, so the window is tight.

Saturday the 29th morning is glassy and clean with a 4ft NW swell, and that same pattern holds for Sunday morning. These are your first real windows of opportunity – small, clean, and manageable. The wave energy sits in the moderate range (275 on Saturday, 262 on Sunday). The standout in this first week is Monday the 31st of August. Morning glass, with the swell building to 6ft from the NW at 9 seconds, and the energy hits 470. Conditions are forecast to be good. This is the one to circle for the first week. It’ll be a bit too much for a total beginner, but for the rest of us, that’s a fine morning session.

After that, it’s a bit of a mixed bag through the next few days, with the wind turning cross-onshore each afternoon. The morning windows stay clean and offer waist to chest-high waves on the 3rd and 4th of September.

Now, looking further out, there’s a proper surge of energy showing up for the morning of Monday the 7th of September. We’re talking a 7ft NW groundswell with a long 13-second period and glassy conditions. The wave energy is through the roof at 1429. This is a big, powerful swell for a reef setup, and it’s really one for experienced surfers only. It’ll be holding some serious power and the sets will be widely spaced. The wind is perfect, though, so for those who know Mutriku, that morning could be the best on offer for the whole 16 days. Just be warned, a wave that size over a reef ain’t for the faint-hearted. It’s a promising call, but still a week and a half away, so keep an eye on it.

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.
