Mutriku Surf Forecast and Surf Report

Alright, let’s talk Mutriku. We’re looking at a sheltered reef break that needs everything to line up, and for the first week and a half, it’s a no-go. The water is warm at 75°, way above normal for this time of year.

The first surfable day shows up around Monday, August 10th, but the swell is tiny at 2ft from the NW with a 9-second period. The wind is glassy in the morning, so it’s clean. The combined wave energy is weak (72), so it’s a log or a learner wave.

We get a few more glassy mornings on the 11th, 12th, and 13th, but the swell stays small—2ft to 1ft—and the energy stays low (65, 64, 39). The wind is perfect, but the ocean is flat.

Friday, August 14th, shows a little more juice. The morning is glassy with 2ft from the WNW at 10 seconds, and the energy is moderate (108). That’s the best of the first week, but it’s not a standout.

The real change hits on Friday, August 21st. That morning we’ve got 6ft of NW swell with an 11-second period. The energy jumps to 851—that’s strong. The wind is light cross-onshore from the ENE, so it’s not perfect, but it’s surfable. This is expert territory on size, and the long period will hold on the reef. Conditions are still a bit marginal.

Saturday, August 22nd, is the gem. The morning is glassy, with 4ft from the NW at 10 seconds and wave energy at 240. That’s clean, solid, head-high. The wind is dead calm, so the faces will be smooth. The swell direction (NW) is exactly what this break wants. This is the day to paddle out. Crowds are possible, so be early.

After that, Sunday the 23rd drops off fast—2ft and messy cross-shore wind.

So, for the whole 16-day window, there’s a long stretch of tiny, clean waves that aren’t worth chasing, then a short, punchy window of real, glassy surf on the 22nd. That’s your one and only standout.

Rusty.
