Mutriku Surf Forecast and Surf Report

Alright, Rusty here, and let's have a look at what the charts are telling us for the next couple of weeks. It's a bit of a mixed bag, but we've got some moments worth paddling out for.

The first bit of the forecast period is pretty quiet. We're looking at a few days of small, weak waves and a lot of "poor surf conditions" flags. There's a bit of a ramp-up towards the end of the first week, but don't expect a blockbuster. The main event for the whole window is shaping up around Saturday the 5th and Sunday the 6th, but even then, it's not a perfect picture.

Let's start with the standout, which is Mutriku. This is an inconsistent reef break, so when it lines up, it's a special thing. The best opportunity is going to be on the afternoon of Saturday the 5th. We've got a solid NW swell coming in around 5 ft, with a very long period of 13 seconds – that's pure groundswell with some serious energy. The combined energy is strong at 758, so it's got some grunt. This long-period stuff really suits a reef like Mutriku. The wind is light and from the east, giving it a cross-on angle, which isn't perfect glass, but it's manageable. The water temperature is sitting at 74°, which is a massive 4° warmer than normal for September – a real anomaly, and it’ll feel like a warm bath. The tide and conditions are "marginal," but this is the biggest, most powerful swell of the whole outlook. For a spot that’s inconsistent, this is the one to circle.

Saturday morning, the 5th, is also worth a look. The swell is smaller at 3 ft, but that long 11-second period (combined energy of 310) from the NW will still offer some nice shape. The wind is glassy from the ESE, so it'll be clean, but the waves are just going to be smaller.

Moving into Sunday the 6th, the swell drops a bit by morning. We've got a 4 ft NW swell with a 12-second period (494 energy) but the wind picks up from the NW, putting it on a cross-shore angle. It's doable but not as clean. By the afternoon, it gets a touch bigger at 6 ft and 11 seconds, pumping out 970 energy, but the cross-shore wind is stronger at 15 km/h (9 mph), so it'll be a bit of a chop battle. That's getting into expert-only territory for the size.

After that, from Monday the 7th onward, the energy really drops off. There's a long lull. Monday morning the 7th is completely flat with a 3 ft swell and glassy conditions, but it's just not very good. The next notable blip is not until over a week later, on Tuesday the 16th of September. We get another NW groundswell, 4 ft at 11 seconds with 358 energy, and it's glassy in the morning. That could give a few rideable waves, but it's nothing like the Saturday before.

Tuesday the 15th has a pulse of 102 energy, but it's small and blown-out, and the 18th of September has a similar story with a glassy 3 ft swell. In short, if you're surfing Mutriku, the absolute call is the afternoon of Saturday the 5th. It's inconsistent, so you have to make the most of it when it shows up. For the rest, it’s mostly small and ordinary.

Stay stoked,
Rusty
