The Lowdown
Alright, Rusty here. Let’s break down what’s coming for Mutriku.
It’s dead flat to start. Nothing worth getting wet for in the first few days. The water’s at 76°F – way warmer than usual for this time of year, so you’ll be comfortable just chilling, but the waves are missing.
First real chance comes Friday morning, August 28th. Mutriku (a sheltered reef break) picks up a 6ft swell from WNW with an 8-second period. Offshore wind from the SSW at 9 mph keeps it clean. The combined energy is 330 (moderate). It’s surfable but ordinary – not your best day.
The big standout is Tuesday morning, September 8th. Mutriku gets hammered with an 12ft swell from the NW, 10-second period, and glassy conditions. The combined energy is a massive 2833 (very strong). That’s a heavy groundswell hitting a reef – it’ll be powerful, well-shaped, but at that size it’s for experts only. Beginners, don’t even think about it.
Before that, Saturday the 29th and Sunday the 30th of August offer small clean waves. Saturday morning has 5ft from NW (9-second period) with glassy wind and 349 energy. Sunday morning drops to 4ft (8-second period) with glassy wind, energy at 201. Both are ordinary but clean enough for a fun longboard session.
The second week is hit or miss. Wednesday morning, September 2nd, has 5ft from NW (10-second period) with calm winds and 391 energy – surfable, nothing special. Then Thursday and Friday the 3rd and 4th are messy with cross-onshore winds.
Saturday morning, September 5th, brings an offshore southerly breeze at 3 mph with a tiny 3ft swell from NW (8-second period) – weak but clean.
Monday morning, September 7th, goes glassy again with a 4ft NW swell (10-second period) and 231 energy. Ordinary but clean.
Then Wednesday the 9th drops off with 6ft from NW but cross winds and a short 8-second period. Just average.
If you’re waiting for the one true session, it’s Tuesday morning, September 8th. Big, glassy, and powerful – a top-tier day for the experienced crew at Mutriku.
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.
Mutriku is 16 km (10 miles) from Eibar. If you plan a holiday in Pais Vasco, look for hotels and other accommodation in Eibar. Eibar has rooms for a wide range of budgets as well as car hire and transport links.
