Mutriku Surf Forecast and Surf Report

Alright folks, Rusty here. Let’s have a proper look at what’s on the cards for the coming weeks.

First off, I gotta be straight with you – it’s a tough run ahead. The water is sitting at a balmy 75°, which is a couple of degrees warmer than usual for this time of year, so you’ll be comfortable in a spring suit, but the surf is not playing ball.

Looking at the whole 16-day window, there’s a big gap of nothing worthwhile at the start. From Tuesday, August 4th right through until the morning of Tuesday, August 12th, it’s all poor surf conditions. The swell is tiny, mostly under 3ft, and the period is short, so there’s just no grunt to work with. The combined swell energy is weak, barely cracking 100 (44-116 range) for most of that time, meaning the ocean is flat and unenthusiastic.

Now, the first real glimmer of hope comes on the morning of Wednesday, August 12th. Mutriku is a reef break that’s inconsistent and sheltered, so it needs the right conditions. The morning session shows a 3ft swell from the NW with a 10-second period, and the wind is glassy – dead calm. This is a major positive. The combined energy hits 177 (moderate), which is the best we’ve seen. The waves are described as “surfable but very ordinary,” so it’s not going to blow your mind, but it’s the only game in town. The direction from the NW is a good match for the break’s optimum. If you’re a beginner, this 3ft is fine, but remember it’s inconsistent, so you’ll be waiting for sets.

After that brief moment, we slide back into poor conditions. The swell drops again, the wind turns cross-on, and the combined energy dips back under 100. The rest of the week (August 13th to 15th) is a write-off – tiny swell and messy side-shore breezes.

The next potential highlight is on Saturday, August 16th. The morning of the 16th shows glassy conditions with a 2ft swell from the NW, period of 9 seconds, and combined energy of 128 (moderate). It’s a clean, small wave setup. The NE wind is offshore for Mutriku, which is exactly what we want. It’s again “poor surf conditions” in the data, but with glassy offshore wind and a bit of energy, it’ll be the most user-friendly wave of the whole run. This is your best bet if you want a clean, small wave session.

Later in the second week, on Monday, August 18th, the morning shows another glassy window with a 3ft, short-period (6 seconds) NNW swell. The combined energy is weak at 62, so it’s a dribbler, but it’s clean. For the experienced surfer, the longer period swells (10-11 seconds) on August 9th and 11th actually had more size (3ft) and combined energy (214), but the wind was cross or onshore, ruining the shape. For a reef like Mutriku, a clean, small day is still a good day.

The standout, if you can call it that, is Wednesday morning, August 12th, for the first clean, glassy surf with the best energy. The second standout is Sunday morning, August 16th, for another clean, glassy session with a bit more size. Both are small, but that’s the best we’ve got.

Rusty out.
