The Lowdown
Alright, I’m Rusty, and let’s talk about what’s coming up in feet and miles per hour.
The first real swell doesn’t show until Thursday the 17th. From the 14th through the 16th, it’s small and choppy – weak energy, cross-onshore wind, just not worth it.
Thursday the 17th morning brings a 6ft NW swell with an 11-second period, energy at 659 (moderate). Wind is light cross-onshore, so it’s a little bumpy. Friday the 18th morning cleans up nicely: 3ft NW swell, 9-second period, light cross-offshore breeze, energy at 205. That’s clean and surfable for the experienced.
The standout is from Saturday the 19th through Monday the 21st. Saturday morning: 7ft NW swell, 13-second period, energy at 1657 – that’s strong. Wind is light cross-onshore, but this is for experts only. Water temp is 73°F, which is much warmer than normal – about 5°F above average.
Sunday the 20th morning: 4ft NW swell, 11-second period, glassy calm wind. Energy is 468, moderate. That’s clean and perfect for intermediate surfers. Mutriku (reef) is inconsistent and sheltered, but when it’s glassy, it’s a treat. Crowds are sometimes around.
Monday the 21st morning: 5ft NW swell, 12-second period, glassy. Energy at 712, moderate to strong. Another clean, powerful day.
After that, it fades fast. Tuesday the 22nd morning is clean with a 4ft swell, but by Wednesday the 23rd, the waves drop to 1-2ft. From then on, it’s tiny and flat through the end of the month, with only a few glassy moments but no real surf.
Best bets: Sunday the 20th and Monday the 21st mornings – clean, glassy, and solid NW swell. Saturday the 19th morning for the big stuff. After that, it’s a long dry spell.
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.
