The Lowdown
G’day, I’m Rusty, and I’ve been staring at the charts for your local patch. Honestly, it’s a pretty grim run ahead. The swell window is just struggling to light up, and most of the days are a write-off. Let’s break it down.
The first real chance to get a wet suit on comes on Monday, 31 August, at Mutriku (a reef break). The water is sitting at 74°F – that’s 4°F warmer than usual for this time of year, so it’s much warmer than normal. The morning is the pick: a clean 6 ft swell from the NW with a solid 10-second period, and the wind is glassy (calm, 3 mph from the WNW). Combined swell energy is moderate (585). That’s a standout session – clean, punchy, and the reef will shape it up nicely. It’s a sheltered spot, but the swell direction (NW) is perfect for the optimum direction. Crowds are possible here, but with conditions this good, it’ll be worth it.
The next real highlight is Saturday, 5 September. Early morning, Mutriku again. We’ve got a 5 ft NW swell, 13-second period (long period groundswell), with glassy offshore ENE wind at 3 mph. The energy is strong (853). This is promising but it’s a week out, so keep an eye on it. That long period will be best at this reef, as it might break a bit too straight on a beach break. The difficulty is beginner-friendly, so it’s accessible if the sets are manageable.
After that, the rest of the 16-day window is a real struggle. There are days with glassy conditions but tiny swell (1.0 ft to 3 ft), and the energy is weak (mostly under 100). A few mornings like Thursday, 3 September, and Wednesday, 9 September, are glassy but flat as a pancake. The later parts of the second week – from around 10 September onward – are mostly small, weak, and messy. The combined swell energy barely hits double digits, so don’t get your hopes up.
The runs of poor surf conditions are long – there are gaps of several days with no real recommendations. It’s a quiet spell for the area, but sometimes that’s just how it goes. The reef at Mutriku is inconsistent, so these blank runs aren’t unusual.
In short: Monday 31 August morning is your best bet – clean, glassy, and a solid 6 ft from the NW. Saturday 5 September morning is a promising long-range call. Everything else? Leave the board in the car.
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.
