Mutriku Surf Forecast and Surf Report

Alright, this is Rusty. Let’s have a look at the Basque coast, specifically Mutriku.

To be straight with you, the next week or so is pretty flat and ordinary. The swell is there, but it’s tiny and the wind’s not doing us any favours. From Monday the 17th right through to the morning of Thursday the 20th, we’re looking at ankle-to-knee high dribble with mostly cross-onshore or onshore breezes. The water is sitting at 25°, which is much warmer than usual for this time of year – like having a lukewarm bath. But that’s about the only highlight. Not worth paddling out.

Thursday morning the 20th is where we finally get a pulse of life. A fresh NW groundswell rolls in, 1.1m (4 ft) with a period of 11 seconds, and the energy jumps to a moderate 284. Glassy conditions too. This is *surfable* but still pretty average. The afternoon gets chopped up by an onshore breeze, so aim for the early session.

Friday the 21st sees the swell bump to 1.4m (5 ft), period still at 10 seconds, energy at 426, but it’s cross-onshore with a bit of rain. Marginal. The weekend into early next week is a waiting game – small, messy, not worth your time. We get a few glassy mornings, but the swell is too weak.

Now, here’s the real story. Skip ahead to Saturday the 29th of August. That morning is the absolute standout of this whole outlook. Mutriku reef lights up with a massive 4.5m (15 ft) NW groundswell, period stretching to a very long 14 seconds, and the combined energy is an enormous 7386 – that’s a proper pulse. The wind is glassy, calm, clean. This is heavy, expert-only territory. Over 2.5m (8 ft), so don’t even think about it if you’re not rock-solid. For the experienced crew, it’s going to be epic. The long period means it’ll hold up well on this reef, but be ready for long lulls between sets. The morning is the window; the afternoon picks up a cross-onshore breeze and gets a bit lumpy.

Sunday the 30th backs off to a still solid 2.3m (8 ft) with a 10-second period, clean again in the morning. Good, but not the stand-out. And Monday the 31st keeps it going at 2.3m (8 ft), clean with a cross-offshore breeze in the morning, but the wind builds through the day.

Overall, the first 12 days are pretty bleak. The real deal is that Saturday the 29th morning session. That’s the one to circle on the calendar – promising, but we’re a long way out, so keep your fingers crossed.
