The Lowdown

Alright folks, Rusty here. Let's have a look at what we've got cooking for Mutriku over the next couple of weeks.

First up, I gotta be straight with you—the start of this forecast is a real bummer. The water is sitting at a very unusual 76°, which is much warmer than normal for this time of year, but that’s about the only good news. From Friday the 21st of August all the way through to the morning of Friday the 28th, it’s a total write-off. We’re talking nearly a full week with nothing worthwhile. The swell is tiny, the wind is messy, and there’s just no energy to work with.

Now, the first real glimmer of hope comes on Friday morning the 28th of August. Mutriku (a sheltered reef setup) finally wakes up. We get a solid 8 ft NW swell, and the wind is dead glassy—dead calm. That’s a rare combo. The wave energy is pumping at a strong 1012 (combined energy). This is the standout of the whole outlook. For the experts out there, this is your window. The water should still be warm, and if you can get in before the crowd builds (it can get busy here sometimes), you’ll be laughing. The afternoon turns a bit onshore though, so make sure you’re on it early.

Saturday the 29th and Sunday the 30th still have some size, with 5 ft to 6 ft NW swell on Saturday morning (clean with a cross-offshore breeze) and 4 ft on Sunday morning (glassy again). These are good, solid options but not quite the epic of Friday morning.

After that, it gets quiet again for a few days. A bit of a lull through the end of August and into the start of September.

But hold onto your boards, because on the morning of Thursday the 3rd of September, we get our second standout. A 6 ft NW groundswell rolls in with a very long 12-second period. The combined energy jumps to a massive 1088, and the wind is clean and cross-offshore. This will be a proper, powerful groundswell—the kind that wraps into Mutriku’s reef and offers some seriously good shape. Keep in mind, with such a long period, it might wall up a bit, but for a reef setup like this, that usually means better, more lined-up waves. The only downside is the afternoon gets a strong cross-shore wind, so again, the morning session is key.

Saturday the 5th of September also shows some promise with a 7 ft WNW swell and glassy conditions in the morning, but by then we're in the second week and things are a bit less certain.

So for my money, if you’re chasing the best, circle Friday the 28th of August morning and Thursday the 3rd of September morning. Those are your two real standouts.

Stay stoked.

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.
