The Lowdown
Alright, Rusty here. Let’s have a look at what’s on offer around Mutriku.
Right off the bat, I gotta be straight with you – we’ve got a bit of a slow start. The first few days are flat, or just onshore mush. The combo energy is weak, with values as low as 12, so nothing’s breaking with any real push. The water is sitting at 76°, which is a solid 5° warmer than usual for this time of year – that’s a real treat, feels like summer has overstayed its welcome.
The first real chance to get wet comes Thursday morning, 20 August. The swell bumps up to 4ft from the NW with a period of 11 seconds, giving a moderate energy of 263. It’s glassy, which is a major plus – the surface will be clean, no wind to mess it up. The waves are ordinary, not firing, but it’s a start.
Friday morning, 21 August, is where things get a bit more interesting. We’ve got 5ft of NW swell at 10 seconds, and the energy jumps to 478. The wind is light and cross-offshore from the SW, so it’ll be clean. That’s a solid session for a confident surfer – the swell is over 5ft, so it’s a bit much for beginners, but for the experienced crew, that’s a good morning.
The standout in this whole 16-day window is the afternoon of Tuesday, 1 September. The swell is 6ft from the NW, with a period of 11 seconds, and the energy is a strong 659. The wind is light and cross-offshore from the SW, meaning the waves will be clean and well-shaped. That’s a long-period groundswell, so it’ll have good power and long lines. At Mutriku, being a reef setup, that’s a recipe for proper waves. The water is still warm, and the crowds are sometimes a factor, but with that quality, it’s worth sharing a few.
The morning of Wednesday, 2 September, is also promising – 5ft of NW swell, same 11-second period, 600 energy, and clean offshore wind from the SSW. That’s another strong session, but the afternoon gets messy with cross-shore wind.
Overall, the first week is a slow grind, but the second week – especially the 1st and 2nd of September – delivers the goods. The energy is strong, the direction is right for the break, and the wind is favourable. If you can wait, that’s the time to paddle out.
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.
