Mutriku Surf Forecast and Surf Report

Alright folks, Rusty here. Let’s have a look at what’s on offer for the Basque coast, focusing on Mutriku.

Right off the bat, I gotta be honest with you – the first few days are a write-off. Wednesday the 2nd through to Friday the 4th, it’s flat and messy. Tiny little 2ft to 2ft swells with no energy to speak of (combined energy between 28 and 73). The wind is all over the place, and the water’s way warmer than usual for this time of year – a real oddity at 74°.

The first sign of life comes early on Saturday the 5th. That morning, we get a bit of a pulse. The swell jumps to 4ft from the NW with a nice long 13-second period (groundswell). The energy kicks right up into the moderate range (443) and the wind goes glassy. That’s your first real window. Mutriku is a sheltered reef break, and that long-period NW groundswell works a treat on a setup like that. It’s an inconsistent wave, so you might have to wait for the sets, but when they come, they’ll be clean and lined up. Just know this spot does get a crowd sometimes.

Sunday the 6th morning is another solid call. Still 4ft from the NW, period still holding at 12 seconds, and we get a clean offshore breeze out of the south. That’s a beautiful combo for Mutriku. The energy is still solid (497). The afternoon gets a bit lumpy as the wind swings cross-shore, so make the most of the morning.

Monday the 7th morning is glassy again with 4ft at 9 seconds, but it’s a bit ordinary energy (242). It’s surfable, nothing special.

We then hit a bit of a lull. Tuesday the 8th and Wednesday the 9th are plagued by onshore and cross-onshore breezes, bumping up the swell size to 5ft–6ft but with poor conditions.

Things turn again on Thursday the 10th morning. The swell is a clean 5ft from the NW, 11-second period, and a cross-offshore wind from the west. That’s a good sign for a reef break like Mutriku. Energy is solid (497). The afternoon, however, sees the swell jump to 8ft but the period drops right off to 8 seconds, making it a jumbly, choppy mess.

After that, it’s a long, sad stretch. From Friday the 11th right through to the end of the forecast on the 17th, it’s mostly small, weak swells (1ft to 4ft) with either glassy but gutless mornings, or onshore winds kicking up crud. There are a few glassy morning windows (like the 15th and 16th) where you *might* get a grovelly 3ft wave, but the energy is weak and it’s really just for getting wet, not for a good session.

The Best of It: Your standout session is hands-down Saturday morning, September 5th. That 4ft NW groundswell with a 13-second period and glassy conditions is the cleanest, most promising combo in the whole window. Sunday the 6th morning is the close second, with a bit more size and an offshore wind. Lock those in, because after that, it’s a long wait for anything worthwhile.

Rusty.
