Mutriku Surf Forecast and Surf Report

Alright, Rusty here, giving you the outlook for Mutriku in local terms. The next couple of weeks have a quiet start and a big wait for something decent, so keep your expectations level.

For the first few days of September, it’s basically flat and not worth a paddle. You're looking at weak swells, mostly under 1 ft to maybe 2 ft, and the wind is onshore or cross-shore more often than not. Friday the 4th is calm and glassy in the morning, but there is just no juice in the water.

Saturday morning the 5th you finally see some life, as a moderate NW groundswell with a long 11-second period builds in. The energy is moderate, but by afternoon the wind shifts onshore and messes up the surface. It’s a tease.

Sunday the 6th is your first real chance. The morning starts with a light offshore breeze from the SW and a clean 5 ft NW swell with a 12-second interval. The wave energy is moderate, and during those early hours, the face should be clean and rippable at the reef. The crowd situation? It can be inconsistent here, but on a weekend morning with clean conditions, expect company. You’ll get the best of it before the wind goes cross-shore later.

From Monday the 7th onward, it’s back to mostly tiny surf with poor to average winds. Most mornings are glassy but have less than 3 ft of weak, short-period swell. For a reef break that doesn’t always fire, it’s a stretch to call it surfable.

The clear standout is Sunday, September 13th. That morning you’ve got a solid NW groundswell at about 6 ft with a 13-second period pushing strong energy (1042). It is glassy, with clear skies and a light wind from the NNE. This is an excellent window for intermediate to advanced surfers who know the reef. Good lines, plenty of push, and clean conditions.

After that pulse fades, the following days offer mostly small, clean morning sessions with 2 to 3 ft NW swell, periods holding up around 10 to 11 seconds, but not much power. Worth a morning paddle but nothing special.

So, to break it down: the first week is lean, Sunday the 6th offers the first clean session, and Sunday the 13th is the real highlight. The water is running notably warmer than usual for September, so a thinner suit will work fine.

Stay patient, keep an eye on the wind, and I’ll catch you in the lineup.

Rusty.
