The Lowdown
Alright, Rusty here. Let’s have a look at what’s cookin’ for Mutriku over the next couple of weeks.
First off, it’s a pretty slow start. We’re looking at a few days of flat, messy conditions through Tuesday and Wednesday. The water is sitting at a balmy 73°, which is about 5° warmer than usual for this time of year – that’s notable, feels like a late summer bath.
The first proper sign of life shows up on Thursday the 17th in the morning. There’s a NW swell pushing 5ft with a moderate period of 11 seconds and a decent kick of energy (606). Winds are light cross-onshore though, so it’s not gonna be pretty – definitely just a marginal session for the keen ones.
Friday the 18th’s morning is worth a mention. The swell drops back to 3ft from the NW, but the period holds at 9 seconds and the wind turns cross-offshore, leaving things clean. It’s small, but for a sneaky longboard or a fish, that’s a window. Combined energy is moderate at 220.
Now, Saturday the 19th is the standout. That morning is looking proper: 7ft of NW groundswell with a long 13-second period, and it’s glassy – ENE wind at just 3 mph. Big energy too (1657). This is the pick of the whole run. It’s a reef break that’s sheltered and inconsistent, so take that on board – you might have to wait for the set, but when it comes, it’ll be clean and lined up. That size is into solid intermediate territory, not for beginners.
Sunday the 20th morning is still fun: 5ft, NW, 12 seconds, glassy as a mirror, with decent energy (576). Good, clean, but not as powerful as Saturday.
Monday the 21st repeats the pattern – glassy morning, 5ft at 12 seconds, clean. Solid option.
Tuesday the 22nd stays clean but drops to 4ft. Still glassy, still NW, still a decent wave.
After that, the swell fades for a few days – we’re into small, clean but weak surf through to the 26th.
Then on the 30th of September, we get another promising pulse: Wednesday morning brings 6ft NW at 11 seconds with glassy conditions and strong energy (716). That’s a good one to pencil in for the second week – clean, punchy, and well worth a look, though it’s a ways out so keep an eye on it.
All in all, this spot doesn’t stay flat for long. The real highlight is that Saturday the 19th – get on it if you can.
Rusty.

Information about the Mutriku Surf forecast
The above surf forecast table for Mutriku provides essential information for determining whether the surfing conditions will be good over the next 16 days. A general guide to surfing at Mutriku can be found by selecting the local surf guide option on the grey menu. Our Mutriku surf forecast is unique since it includes wave energy (power) that defines the real feel of the surf rather than just the height or the period. If you surf the same spot (Mutriku) regularly then make a mental note of the wave energy from the surf forecast table each time you go. Very soon you may start to choose your surf days based on the wave energy alone combined with our forecast of favourable offshore wind conditions. Our star ratings will help here and of course you will also find the usual wave height and period predictions on our surf forecasts as well as a full break down of the swell components under our advanced users option (to reveal that, click the little Einstein character under the tide times).
Further information to help with frequently asked questions about our surf forecast for Mutriku may be found under the help tab on the top menu and also by moving your mouse over the question marks on the surf forecast table itself. Please always bear in mind that the forecast is for near-shore open water and local factors at each surf break influence the actual breaking wave height, such as the beach / reef profile, water depths offshore and shelter.
